I didn't get the piping yet to redo my return line, but I am preeeeetty sure it is the problem.

What I've found so far...

1. Underhood smoke is coming from oil and degreaser soaked header wrap from the PCV valve popping off.

2. The car starts fine, idles and drives normal

3. Idling, the exhaust is normal. Under load, it smokes. (Which could mean that when it's under boost, it smokes )

I should have time to get a new return line installed tomorrow. I just might seperate the downpipe from the turbo to see if there is any oil in it, like if a seal in the turbo blew.
