Top 5 Causes Of Internal Oil Leak
If you notice that your car is burning oil, it could be due to several reasons. Here are the top 5 causes of an internal oil leak:
Worn or Faulty Piston Rings:Piston rings help seal the combustion chamber, allowing the engine to compress air and fuel properly. If these rings wear out or become faulty, it results in an internal oil leak. |
Cracked or Warped Cylinder Head:The cylinder head is an integral part of the combustion chamber. If it develops a crack or becomes warped, it can result in an internal oil leak. |
Worn Engine Bearings:Bearings are crucial for the proper functioning of the engine. If they suffer from wear and tear, they can cause an oil leak. |
Damage to Valve Seals:Valve seals prevent oil from entering the combustion chamber. If they get damaged or become worn out, they can cause oil to leak into the chamber. |
Faulty Engine Gaskets:Gaskets play an important role in sealing vital components of the engine such as the cylinder head, oil pan, and valve cover. If any of these gaskets fail, it can cause oil to leak internally. |
If you suspect that your car is burning oil, it is essential to have it checked by an experienced mechanic to identify the root cause of the internal oil leak. Ignoring the issue can lead to more severe and expensive problems in the future.
