93 mtx oil smoke on deceleration.

[austindavis1993]

I was just wondering if this could be caused by the pcv system and if so what can be done to correct it, everytime i use compression to stop my car, i see a good amount of oil behind me, but doesnt really do it under hard acceleration. Any help is appreciated!

does it also puff a cloud when you first start it in the morning? because if it does, then valve stem seals the the most likely culprit.

the pcv system does not do a good job of oil separation, so if there is a bunch of oil getting up into the intake, then your symptoms could be from that too. if you re-route the pcv stuff to include a catch-can, then you can eliminate most of that oil, but you do need to remember to empty the catch-can...

Valve stem seals. The vacuum created on decel while in gear will pull oil through the worn seals, causing the smoking.
