I have a problem: after engine brake with high revs (over 4000 RPM), if I give gas, then thick blue smoke comes from the exhaust. In any other case (after low RPM engine brake, normal or hard acceleration, cold start, etc) there isn't any smoke.
The car is a 1996 GTV 2.0 TS.
Because of this, I thought, it would be a good idea to change the PCV valve (71713715
), but my engine has an aluminium intake manifold (not plastic), and the breather hose goes in the throttle body.
Here is a metal connection piece, is this the PCV valve?
If so, what is the part number of this one?
I had to change the breather hose because a fire, caused by I broken spark plug
I think the oil consumption (Selenia 20k) isn't too high (~1-2 dl / 500 km), but I need to check this later.
By the way can this symptom caused by overfilling the engine oil?
I will also change the intake gasket, and seal the variator solenoid
