Hi , guys is it normal for the pcv valve to leak oil in to the TBody, ? help thanks!! when i change the thermostat housing found quite amount of oil inside the intake manifold, also have the codes p0400 and p1000 pending , , thanks alot..

 

The engine sucks air through the sump via the TB and picks up oil vapour/droplets which can

condense in the pipework and then enter the engine.

If you drive very sedately this oil builds up and does not get into the engine until you
accelerate quickly.

Some oil is normal,I suggest you find a section of straight road and kick it down hard to clear the pipework.

Watch for smoke in your rear view mirror.
