I over filled my oil and I think that why my car is blowing blue smoke, I do notice some leakage around the area where the rear main is and the oil pan underneath, but not enough to spill onto the driveway, could these be the reason of overfilling that caused it to leak and blow out blue smoke?

 

im wondeing the same thing

 

if u have too much oil it will not allow it to drain back. If it cant the bears burn the oil or it pushes into the turbine section and burns.... So yes it can be a problem!

 

I had just gotten my oil changed before one of the track events and about 5 minutes after each run I would get oil smoke coming from what looked like the transmission tunnel. The oil level stayed full the whole event and there was no oil leaking on the ground of anywhere I could see. The next event I went to the oil was not at the full line. I never saw the smoke that time. I'm not sure what this says about anything so draw your own conclusions.

 

Yeah, it sure will cause it. I overfilled about a full quart! and i got leaks on my driveway and smoke on startup (both from exhaust and engine bay). Drained it to correct level and all problems went away.
