Does My BMW Keep Losing Oil? There Is No Leak Whatsoever
Why
This may seem like a mysterious phenomenon, but in reality, it's not.
It is simply a sign of internal oil leaks.
That’s what we will discuss here.
If these rings get damaged then your car engine will lose oil internally.
PCV valve prevents the emission of unburned hydrocarbons into the atmosphere.
To do so, it channels blow-by gases present in the crankcase to the intake manifold.
If it goes bad, the pressure within the system will skyrocket.
And, the oil will leak into the combustion chamber as a result.
that can result in internal oil leaks in a car is a blown head gasket.
A vehicle will perform poorly if its head gasket is blown.
Cracked cylinder walls can also result in internal oil leaks in a car.
So, these are some of the reasons why a car may lose oil without an external leak.
Appropriate action should be taken to prevent any serious engine problems.
