In this article, we will examine some common causes of diesel power loss during acceleration and explore potential solutions to address it!

A car’s engine generates power by combining air and fuel to initiate combustion. The energy generated by this combustion is then transmitted to the vehicle’s wheels, propelling the car forward.

The engine’s main role is to execute this process consistently with optimal efficiency. Nevertheless, for various reasons, the engine may lose power, leading to decreased performance.

Reasons Why Diesel Cars Lose Power During Acceleration

Faulty Fuel Filter

The fuel filter plays a crucial role in filtering the fuel before it enters the engine. When the fuel filter is clogged, it hinders the fuel flow to the engine, resulting in decreased engine performance. You may notice a lack of power during acceleration and occasional jerking.

To resolve this issue, locate the fuel filter, which is found in the engine compartment or near the fuel tank in your car’s trunk. If you have the necessary skills, replace the clogged fuel filter yourself or take your vehicle to a local mechanic to have it replaced.

Clogged Air Filter

For the proper functioning of the engine, clean air is essential. If dust and other particles infiltrate the combustion chamber, it can damage the engine.

To ensure a continuous flow of clean air to the engine, an air filter is used. However, this filter becomes ineffective after about 15,000 to 30,000 miles, depending on driving conditions.

Neglecting to replace the air filter when needed will lead to a noticeable drop in your car’s performance.

Clogged Exhaust System

The role of the exhaust system is to expel harmful and unnecessary gases from the engine. The faster these gases are expelled, the sooner the engine can initiate combustion, resulting in increased engine power.

Conversely, obstructions such as a restrictive catalytic converter or a clogged exhaust harm engine performance.

Although aftermarket cleaners can resolve clogged catalytic converters, using a quality fuel system additive every 3,000 miles can help reduce the contaminants that lead to clogging in the first place, thus eliminating the need for unclogging.

MAF Sensor Malfunction

The Mass Air Flow (MAF) sensor measures the air intake required for acceleration.

It transmits this measurement to the Engine Control Unit (ECU), which adjusts the throttle accordingly. A faulty MAF that inaccurately measures airflow can lead to significant power loss.

These sensors can deteriorate due to heat and dust buildup. Regularly cleaning them with specialized products can improve their functionality and, consequently, engine efficiency.

Oxygen Sensor Malfunction

While the MAF measures incoming air, the oxygen sensor measures the gases exiting the engine. It is typically located in the exhaust pipe. When MAF readings align with oxygen sensor readings, it indicates your car is running well.

The oxygen sensor also impacts the fuel injection system, making its proper functioning crucial for your car’s performance.

A faulty oxygen sensor can lead to a rich air-fuel mixture, which harms fuel economy. Fortunately, replacing this sensor is relatively inexpensive and simple.

Carbon Buildup on Fuel Injectors

Fuel injectors play an essential role by introducing fuel into the combustion chamber under high pressure, similar to a spray.

Precise fuel delivery is crucial for proper combustion, as even a slight miscalculation can disrupt the combustion cycle, leading to power loss or, in extreme cases, damaged pistons.

Carbon buildup, often caused by poor-quality fuel, can hinder the injectors’ ability to spray fuel into the cylinders, resulting in decreased performance. This issue can be resolved by using a high-quality fuel system cleaner.

Weak Fuel Pump

The main function of the fuel pump is to supply fuel from the tank to the engine, which requires sufficient pressure. Insufficient pressure can prevent the fuel injectors from delivering the correct amount of fuel to the combustion chamber, leading to diesel power loss during acceleration.

Even if a faulty fuel pump doesn’t cause issues at low speeds, it can hinder rapid acceleration. Fortunately, replacing a fuel pump is a straightforward process.

FAQ

1. Are there engine-related issues that can cause diesel power loss during acceleration?

Yes, engine problems such as worn piston rings, damaged valves, or a faulty turbocharger can lead to power loss. It is essential to perform a comprehensive engine inspection to identify such issues.

2. How can I prevent power loss in my diesel engine during acceleration?

Regular maintenance, including changing fuel filters, cleaning or replacing air filters, and adhering to the manufacturer’s recommended service intervals, can help prevent power loss.

Additionally, using high-quality fuel and avoiding overloading the engine can also contribute to better performance.

3. What role does the turbocharger play in diesel engine power loss during acceleration?

The turbocharger increases the intake air pressure, thereby enhancing engine performance. If the turbocharger is faulty or not functioning properly, it can lead to power loss during acceleration.

4. How can I identify a faulty turbocharger as a cause of power loss?

Symptoms of a faulty turbocharger can include excessive exhaust smoke, unusual noises (such as whining or grinding), and decreased power. A professional mechanic can perform tests and inspections to diagnose turbocharger issues.

5. Can a faulty EGR (Exhaust Gas Recirculation) system affect the power of a diesel engine?

Yes, a faulty EGR system can lead to power loss by recirculating excessive exhaust gases, which can reduce the availability of fresh air for combustion. This can result in reduced engine power.

6. What signs should I look for to determine if the EGR system is causing power loss?

Signs of EGR-related issues can include rough idling, increased exhaust emissions, and a lack of power during acceleration. A diagnostic scan or inspection by a mechanic can confirm EGR system problems.

Watch this video from 8020 Media for more information on the causes and solutions for a vehicle losing power during acceleration in general!

7. Can a dirty or faulty Mass Air Flow (MAF) sensor affect diesel engine power during acceleration?

Yes, a dirty or faulty MAF sensor can provide incorrect data to the Engine Control Unit (ECU), leading to inappropriate air-fuel mixture ratios and reduced power.

8. What should I do if I suspect a faulty MAF sensor is causing power loss?

Cleaning or replacing the MAF sensor can resolve the issue. Consult your vehicle’s maintenance manual for specific instructions on MAF sensor maintenance.

A car’s air conditioning system requires a specific amount of oil to function, just like the engine. You should have a clear idea of how much PAG oil to add to the air conditioning system to protect it from unexpected failure.

Which AC components require an oil refill?

The compressor is the component of the air conditioning unit that needs adequate oil to function properly. The compressor is responsible for compressing the refrigerant and circulating it through the rest of the system. When the refrigerant passes through the compressor, it also carries oil with it, which lubricates the compressor’s moving parts. Normally, it is not necessary to add oil to your vehicle’s existing air conditioning system unless you have changed the compressor or there is a leak, allowing oil to escape from the system.

A compressor requires a sufficient amount of oil for lubrication. It has cylinders to compress the refrigerant gases, which creates heat and friction. The oil present in the system controls this heat and reduces friction by making the parts more slippery.

The other components of the air conditioning system, such as the condenser, evaporator, and expansion valve, do not require lubrication and therefore do not need an oil top-up.

However, it is important to note that if any of these components are replaced due to a malfunction or leak, they must be drained of any remaining refrigerant and oil, and the correct amount of oil must be added to the system when recharging it. This ensures that the system has the appropriate amount of oil for proper lubrication and to avoid damaging the compressor and other components.

If there is a leak in the system, repair it first before adding oil. Otherwise, the system will soon need more oil and could lead to the failure of some parts.

What is PAG oil?

PAG oil, or Polyalkylene Glycol, is specially created for automotive air conditioning compressors. The fully synthetic hygroscopic oil is a compressor lubricant for air conditioning units that use R-134a refrigerant.

In addition to knowing how much PAG oil to add to the air conditioning system, you must also use an oil with the correct viscosity. Each type of PAG oil has a number such as PAG150 or PAG VC-46. This number refers to the viscosity of the PAG, similar to how a number like 10W30 indicates the viscosity of regular engine oil.

PAG oil is highly hygroscopic, meaning it absorbs moisture from the air. Therefore, it is important to keep it sealed in an airtight container until ready for use. It is also important to use the appropriate type of PAG oil for a particular air conditioning system, as different systems may require different viscosities or additive packages.

PAG oil is often used in automotive air conditioning systems due to its high lubricating power and stability at high temperatures. It is also non-toxic and has a low environmental impact, making it a good choice for use in automotive applications.

You should consult the owner’s manual for the correct viscosity of PAG oil for the air conditioning compressor.

Learn how to add PAG oil to the air conditioning system in this video:

How much PAG oil should be added to the air conditioning system 

Like engine oil, PAG oil serves as a lubricant for the compressor and circulates the refrigerant throughout the air conditioning system. However, the exact amount of PAG oil to add to the air conditioning system will depend on several factors: the air conditioner’s design, its capacity, and the type of compressor.

Additionally, the air conditioning system’s compressor will likely have specifications regarding the amount of oil to add. You should consult the owner’s manual before adding more oil.

The air conditioning system of most modern vehicles needs a total of 4 ounces (120 ml) of oil. Therefore, it is wise to consult the manual to be sure of the exact amount and avoid overfilling or underfilling the system. A low oil level can lead to compressor failure, and overfilling will also harm cooling performance.

So, how much PAG oil to add when recharging the AC? Here is the amount of PAG oil that different AC components need for their proper functioning:

• Compressor = 1.4 ounces
• Evaporator = 1.5 ounces
• Condenser = 1 ounce
• Accumulator = 1 ounce
• Hoses = 1 ounce

To ensure that the appropriate amount of PAG oil is added to the air conditioning system, you should refer to the vehicle’s manual and seek assistance from a trusted automotive mechanic.

It is recommended to flush the entire system before adding oil or refrigerant. When replacing a part, such as a compressor or accumulator, you should always add the oil that was lost during the replacement.

However, the total amount of oil added should never exceed the system’s oil capacity. So, when calculating how much PAG oil to add to the air conditioning system, remember to keep the total amount below 4 ounces or whatever your car’s air conditioning system capacity is.

If you drive a manual transmission car, many questions will come to mind, such as “How does a manual transmission work?”, “What moves inside the manual transmission when you shift the gear lever?”.

In this article, we will answer all questions related to the manual transmission and give you a basic knowledge of every essential component of your car’s transmission. Let’s go!

What is a Manual Transmission? (Gear Shift Lever)

Before discovering the answer to the question “How does a manual transmission work?“, you need to understand what a manual transmission is.

The manual transmission, a gear lever or manual gearbox or standard transmission, is a type of transmission where the driver uses a lever to change gears literally.

In the past, manual cars were often equipped with a gear lever or a steering column mounted on the dashboard, but nowadays, in modern vehicles, the gear lever is mounted vertically in the center console and connected to the transmission via linkage.

Shifting gears requires disengaging the clutch disc (which is located between the transmission and the engine) via a third pedal located to the left of the brake. Then release the clutch, select the desired gear, and engage the clutch again.

When stopped, the disc will wear out prematurely if the driver engages the clutch too slowly. And if the driver engages the clutch too quickly, the engine will stall.

Learning how to drive a manual car takes more time than learning how to drive an automatic car, but it’s more fun and easier than it seems.

When you drive a manual transmission car, you will feel that there is a connection between you and your car that is too difficult to replicate with an automatic transmission car.

And another interesting thing is that if you can use a manual transmission, you will be able to drive any type of vehicle. Normally, a basic vehicle is equipped with a 5-speed manual transmission. In more expensive vehicles, a 6-speed transmission is equipped instead.

Various Parts of the Manual Transmission

These brief descriptions of the parts of a manual transmission will help you understand its complex operation.

1. Clutch and Clutch Pedal

Composed of various small components, the clutch transmits engine torque to the transmission. The clutch pedal is a hydraulically operated gear that disengages the clutch when you press it.

2. Flywheel

The circular mass sends engine torque to the clutch disc which interacts with a smooth surface of the wheel.

3. Selector Fork and Collar

This is an arm-shaped gear that helps move the collars along the output shaft. On the other hand, you can select different gears with the collar by locking it onto a particular gear, resulting in the transmission of torque to the output shaft from the countershaft.

4. Synchronizers

These help the gear and the collar to engage with each other and match their speed if there is a difference.

5. Countershaft and Output Shaft

The gears on the countershaft mesh with the gears on the output shaft when the former receives power from the engine.

6. Gears

You will find gears of different sizes in a manual gearbox. The larger ones have more teeth and provide more torque to reduce the car’s speed, while the smaller ones produce less torque so your vehicle can travel at high speed.

How Does a Manual Transmission Work?

So, with all your new knowledge, let’s find out what happens when you shift gears in your manual car and see how the manual transmission works.

• You must press the clutch pedal to disengage before turning the vehicle key to start. This will cut the power between the transmission and the engine’s input shaft. As a result, the engine will be alive without powering the entire vehicle.
• Move the gear lever to first gear, which is located on the output shaft, so that the shift fork moves forward towards the latter. The first gear is connected to a countershaft gear. The countershaft, meanwhile, is connected to the engine’s input shaft via another gear.
• There is a synchronizer collar attached to the shift fork. This helps the driving gear carry power to the output shaft and synchronize their speeds if there is a difference. You engage the vehicle when this collar locks with the first gear, which is securely fixed to the output shaft.
• Now, apply light pressure to the accelerator pedal and remove your foot from the clutch. It will reconnect the engine to the gearbox. Then the vehicle will start moving forward.
• Shift to second gear after pressing the clutch to go faster. This will disconnect the power between the engine and the gearbox. You just need to repeat this process to change gears in order to slow down or speed up the car.

Due to a cracked head gasket, an engine may consume more oil or coolant. Therefore, it is extremely vital to troubleshoot the symptoms of a cracked head gasket.

What is a Head Gasket?

First, if you are still wondering what a head gasket is, we have an answer for you now!

The head gasket is an essential component of a vehicle’s engine system, nestled between the engine block and the cylinder head.

The main function of a head gasket is to seal the internal combustion process so that the two highly flammable fluids—coolant and oil—do not mix.

Now that we understand what a head gasket is, it is necessary to know the symptoms of a cracked head gasket to avoid higher costs due to additional engine damage caused by driving with a cracked head gasket.

In fact, this issue even occurs frequently in Subaru and has become a stain on the company’s impressive record of manufacturing first-class vehicles. To understand the symptoms, it may be helpful to understand why a head gasket can fail.

Symptoms of a Cracked Head Gasket

The symptoms of a bad head gasket are sometimes difficult to diagnose and cost a great deal of money in repair or replacement. The problem with a head gasket starts with a simple leak in the cooling system.

However, it will become a more serious problem if it goes unnoticed due to irregular maintenance. Let’s now look at the symptoms of a cracked head gasket with Car From Japan!

Engine Overheating

The reason may be a lack of coolant or the combustion process. Of course, this can lead to many other problems. For example, metal components may expand, which will cause cracks or deformations.

Engine overheating is one of the most common signs, but not the only one, of a cracked head gasket. So, a simple overheating engine does not mean the head gasket needs to be repaired.

Drop in Coolant Levels

If the coolant level drops more quickly than normal, your car likely has a problem with the head gasket. A cracked head gasket can cause a leak, which will be tested by pressurizing your cooling system and monitoring the pressure loss.

Engine Misfires

When coolant leaks into an engine cylinder, it misfires. Thus, a misfiring engine can be a possible symptom of a faulty head gasket.

Excessive Smoke from the Exhaust

When a large amount of coolant leaks into the cylinders, the smoke from the combustion process comes out of the exhaust system. This usually happens when the initial leak is not addressed in time.

Milky Engine Oil

Another symptom of a cracked head leak is milky white oil. Because coolant leaks into your combustion chamber, it will seep past your piston rings and end up in your oil.

Over time, the oil will mix with this fluid to take on a milky white color. On your dipstick and around the engine oil cap are where you can easily notice this symptom.

How to Avoid a Cracked Head Gasket?

We all know that prevention is better than cure. So you should perform regular car maintenance to avoid all symptoms of a cracked head gasket.

Otherwise, the repair work will drain your wallet very quickly. There are three methods you can use to reduce the risk of head gasket cracking.

• Your combustion chamber should be kept under as low pressure as possible
• Avoid overly advanced timing or carbon buildup in the engine
• Do not downshift to slow your car and restart at any time if your car is equipped with a manual transmission.

Cracked Head Gasket Repair

A cracked head gasket is easy to repair if you can detect the leak early on. There are many sealing products available in auto repair shops. You just need to add the sealant to the radiator, and the leak will be sealed while you drive.

The type of sealant will depend on the number of engine cylinders and the extent of the leak. Normally, sealants will work for small leaks.

However, your car will need a head gasket replacement if the problem is not detected early. You may need to repair the engine block and cylinder head or completely replace the engine only.

A gasket replacement requires the removal of a number of engine components. Reassembling all these parts requires specific torque settings to ensure proper installation.

FAQ on Cracked Head Gasket

1. How long does a blown head gasket last?

When a gasket blows, it can cause significant damage to your vehicle, so it is essential to understand the warning signs and what you need to do to fix it.

A car with a blown head gasket normally does not last more than a month, depending on the severity of the leak or hole.

2. Is it hard to fix a blown head gasket?

It is not easy to replace the head gasket. It requires a superior understanding of the engine and how its components work together.

Due to the depth of today’s engines, the exhaust manifold, cylinder head, and intake valves must be removed to access the head gasket.

3. How much to replace a head gasket?

The head gasket replacement itself is not expensive, but the labor involved in the job requires a large sum of money. In fact, repairing a head gasket is one of the most expensive engine repair jobs.

The typical cost of repairing a head gasket is about $1,000 to $2,000, but this is not due to high material costs but to labor, as we mentioned.

4. What temperature damages the head gasket?

If the engine temperature exceeds 115°C, the head gasket and cooling system can be pushed beyond their usual limits.

The impact is virtually certain if the engine temperature exceeds 126°C. Poor-quality gasoline, which is often responsible for excessive pressure on the cylinder head, is another reason that can contribute to gasket failure.

5. Does a blown head gasket make noises?

Since the combustion chamber is not sufficiently sealed, the combustion of fuel and air will be limited. You may notice that your car’s performance has decreased, and you may even hear an exhaust leak or dull idle noises, which is a clear indicator of a blown head gasket.

6. Is it safe to drive with a cracked head gasket?

Most problems with your vehicle’s head gasket start with a minor crack before being fully blown.

If these cracks are not properly addressed, they will enlarge over time, leading to additional damage and more expensive repairs. That is why you should never drive with a damaged head gasket!

7. Will a car start with a blown head gasket?

When your engine does not start due to a faulty head gasket, you will notice the following symptoms: The engine cranks but does not turn over. The battery drains more quickly with each engine rotation. Even if the starter is engaged, the engine does not start.

If you notice any red or pink liquid leaking from the car, it is necessary to immediately understand what is wrong with your vehicle. A pink or red fluid leak from the car primarily indicates a problem with the transmission.

A fluid leak from a car is generally not a good sign and in most cases, it can cause a lot of panic for the owner.

The fluid used in the transmission is a distinctive red or green color. Therefore, it is easy to determine if the leaking fluid is from the transmission or from elsewhere.

Any expert mechanic will advise immediate solutions if there is a problem in the transmission. But can you drive the car with a leak in the fuel line or in some other transmission components?

Why does transmission fluid leak?

The most common reason is a broken, loose, or worn transmission seal. A transmission has various types of seals, including the input shaft seal, output shaft seal, axle seal, and many more in its mechanism. Damage or a hole in any of these will result in a red fluid leak from the car.

A gap in the transmission could be another potential issue. Fluid could escape if there is a breach or crack in the torque converter, pan gasket, transmission pan, or other areas. It is indeed rare to have a leaking seal or a cracked housing, but not entirely impossible.

A leak in the fluid lines could also be the cause of this problem. This type of damage could result from road debris hitting the fluid lines. Heat could be another culprit for this issue. Remember that a hole in the lines drains the fluid quite quickly.

Is it safe to drive when red fluid is leaking from a car?

Safety depends on the severity of the leak. You can drive for years if it’s just a small drip. There is no need to worry as long as the transmission fluid remains at the proper level. However, it is recommended to fix the leak as soon as possible. It could affect the vehicle’s performance and lead to complete transmission damage.

A low transmission fluid level will warn you through various signs such as slipping, increased RPM, gear hunting, car speed being out of sync with gear shifting and acceleration.

In this case, you should no longer drive the car and call a service center to have it towed to the repair shop.

Ignoring the symptoms will only worsen the problem over time. Eventually, it will end in transmission failure.

Remember that repairing a small leak will not cost much, but it will cost thousands of dollars if the hole enlarges or the transmission stops working.

How to stop the red fluid leak from the car?

There is nothing else to do but take care of the car and bring it to a repair shop for regular maintenance. All transmission seals are made of rubber and wear out with regular driving.

Just like other components such as brake pads and tires, seals also wear out over time. Furthermore, it is not uncommon to have cracks, holes, or damage in various transmission components.

So, when you see a red fluid leak on a car, check the fluid level and take the necessary measures.

Other possible causes behind a red fluid leak from the car

Besides transmission fluid leaks, engine coolant leaks and power steering leaks are two potential culprits responsible for pink or red fluid leaks from the car. Below, we will give you more information about them.

1. Engine Coolant Leak

Engine coolant functions to keep the car engine’s temperature stable by circulating around different parts of the engine, and its color is pink or red.

If you notice that the red or pinkish fluid leaking from the car has a sweet smell and resembles water, it is very likely engine coolant. The place where you are likely to see an engine coolant leak is usually under the engine or the radiator.

To confirm the issue, you need to check the reservoir (it’s a semi-transparent bottle with “low” and “high” markings under the hood) and if you see that the coolant is insufficient, inspect the radiator (it’s located right behind the grille at the front of the car) – that’s what you need to do.

Remember not to open the radiator cap right after turning off the car, as you could get burned by the hot steam.

After removing the radiator cap, you can easily see the coolant level in the radiator, and if it’s impossible to see, it seems there is a leak in your cooling system and you should need a mechanic’s help.

2. Power Steering Leak

Power steering fluid is designed to help the driver turn the steering wheel more easily. So, if this fluid is leaking, you will notice it during low-speed turns and encounter more resistance from the power steering than usual.

If your car’s power steering fluid is leaking, you will typically detect a pink car fluid leak or red fluid leaking from the front of the car (near the front bumper). This fluid has a slight smell of burnt oil and resembles water.

The power steering system should be sealed and protected, so if there is a leak in your car’s system, you should have your car inspected by a specialist.
