Engine smoke

[blackgn231]

Just noticed that when,I slow down only some times that ,I get smoke out the exhaust pipe smells like oil but just not sure whats going on. It runs good wondered if it may be the turbo oil seal? Like I said it only does it sometimes . so thought maybe someone might have a idea more then me if it was the valve seals or a ring it would be doing it all the time right?

Sounds more like the PCV to me.

without doing diagnostics there's no way to know for sure.

I had similar symptoms recently. Turned out to be a bad turbo. Read this http://www.turbobuick.com/forums/threads/smoking-problem.402612/

Check the DP for oil.

I agree with Earl. Need to diagnose. Unplug the pcv and cap the line.

What Earl said, check the PCV.

how excessive does your oil level change on your dipstick ?1 quart every 500 miles? 1 quart in between oil changes knowing how much your losing or burning mite help narrow it down.I'm with earl,mark , pcv
