tailpipe white smoke??

So a couple weeks ago I let my car idle to warm and I come out and there's white smoke out the tail pipe.. I shut it off took the turbo out and had it replaced. There was oil in my turbo, intercooler, and all the lines in between. Put it back together and she drove great for a full week until yesterday the white smoke started coming out of the tailpipe again and the check engine light came on! It could be a head gasket but I haven't seen any signs of over heating? What do you guys think!?

I concur.

Are you monitoring your numbers at all? What are your fuel trims at? Without monitoring you don't know what is going on.

If your PCV is stuck you will push oil into the engine. If it is stuck your fuel trims will be off big time.

When I had my speed I had an ultragauge to monitor and an OCC. I would pump the lines when draining. Pushed a lot of crap out and it worked the PCV.

Actually had fuel trims one time just about 3.9. would never zero out at idle. Drained OCC and pumped the lines. After 0 at idle was solid. My only guess was the PCV was starting to stick.

She ran solid till I traded.
