As of yesterday I noticed white/grey smoke coming out of my exhaust as you rev the engine the smoke comes out as the revs go back down in lower rpms. During normal driving you dont see any smoke

I did a compression and leakdown, #s are perfect. So my next guess would be turbo seals. I did check the turbo for shaft play it has a little but nothing extreme.

Any advice whats causing the smoke?

Maybe the problem is in the head. . .

Can you elaborate on why you think so?Thanks

 

usually white smoke indicates carbon deposits being dumped out. I would try doing a Run Rite or something similar to get some of the carbon deposits out and see if it improves from there on.

Sometimes it is the silly **** that is the culprit. Oh, I heard some positive things about GM headcleaner too. I got a can myself but haven't used it yet cuz you're supposed to do an oil change right after. I still have a few more K miles to go on my synthetic.

 

Seafoam is good for getting carbon out as well

Yeah but it fouls your plugs and 02 sensor sometimes. Not to metion it has to run through the turbo . My guess is if you "feel" shaft play like more then a 1mm that it could be your turbo going out. it could also be your head studs like someone said or a head gasket blowing. Do you feel andy performance since you've seen the white smoke is coming out?
