Does your car smell like burnt oil or old lamps? You’ve probably smelled that common burning smell before. When oil leaks from the exhaust pipe, the entire car inside and out smells of oil.
You cannot eliminate the smell of burnt oil by simply airing out the car or masking the smell with perfume. You should be able to completely eliminate the smell by knowing the cause of the problem and treating it.
Main Reasons Behind the Smell
Here are some common reasons of burning oil smell through vents.
- Changing Oil
- Oil Plug Damage
- Loose Oil Filter
- Damaged Value Cover Gasket
- A Leaking PCV Value
- Leaks Near the Exhaust manifold or pipes
1) Changing Oil
If your car’s oil Change is not done properly, excess oil can end up in the exhaust system. The mechanic must ensure that excess oil does not enter the exhaust system and cause a familiar smell. Combustion is usually caused by the heat generated as the engine heats up, which burns bad oil and creates a pungent smell throughout the vehicle.
Once the leak or spill is eliminated, the oil should burn completely and the smell coming from your car will eventually disappear.
2) Oil Plug Damage
The smell of burnt oil can also be caused by a damaged oil filler cap. There is a plug in the pan to drain the oil when repairing the car. If this cap is damage, the oil will naturally flow in all direction, so when it comes into connect with the heat of the engine, you may smell the smell of burnt oil.
This also causes puddles of oil to form every time the car is parked. This situation must be remedied after the trip so that the vehicle does not run out of oil, etc.
3) Loose Oil Filter
The oil filter may also be loose, which of course leads to an oil leak. The filter may be in this condition because it is not functioning properly due to rough bumps in the road or because it was not installed correctly to begin with.
As the oil burns, its smell spreads throughout your vehicle. Other signs of a loose filter include puddles of oil under the car. This problem can be solved immediately by having a mechanic check the cause of the leaks and close them.
4) Gasket on the Valuable Cover damaged
If your high mileage car is losing to much oil, it may be due to damaged or faulty engine bearings. Oil leaks can also be caused by poor connections or damaged oil seals. If the situation worsens, your car will constantly smell like burnt oil.
These seals, O-ring and washes (oil and value washers are particularly susceptible to damage) are scattered throughout the engine and need to be replaced.
5) Loss of PVC Value
Your car’s PCV value is used to control emissions as it directs exhaust gases from the oil pan to the intake manifold. This helps the engine burn these gases instead of polluting the atmosphere, but can also cause engine compartment and causes a burning smell.
The smell is the least of the problems in this case as it can significantly shorten the life of the engine.
6) Leaks near The Exhaust manifold or Pipes
Finally, there is another reason for the smell of burnt oil in the cockpit: Leaks in the exhaust pipes and manifold. Leaks near the engine compartment can cause oil to get onto the hot exhaust pipes or manifold.
It evaporates instantly, making it difficult to find its source. Along with a leaking value over gasket, this is most common causes of a burnt oil smell.
