Mine 850 is also making some smokes from the exhaust...

When I bought it 3 years ago, it was making blue smoke in several situations and out of the dispstick. Well, replaced the PCV and it solved most of it.

car have been stored for a while, and now that I'm using it again, it does a smoke in two different conditions:

1. Blue smoke when I lift the pedal after "full throttle". Only happens if Turbo pressure is in the last 3/4 of the turbo gauge. Can this be the Turbo? Seems to have some oil around it looking for underneath the car (seal for return oil pipe already replaced).

2. white smoke after with some sulfur smell after some minutes on idle or slow pace. Then, if i floor it couple of times, it will stop. Been told that this can be O2 sensor... ?

Blacky only had one silencer and that didnt smoke at all, i recon the turbo shaft is slightly bent or valve stem seals leaking
