Recently I had an issue with over oiling my turbo due to no restrictor, causing the oil to burn off on the compressor side of the CHRA . This was solved about a 3 weeks ago, and gave very good results as far as solving the smoking turbo CHRA/compressor.... UNTIL recently.

After a few canyon runs and a couple dozen of hairpin turns (maybe an occasional parking lot donut) I realized that it seems something is producing smoke from the same area of the turbo. This smoke is produced when in the middle of acceleration on a right turn/sweep/slide. Basically whenever the momentum of the car and gravity are pushing the liquids up against the drivers side of the car enough, is when I see smoke.

Any guesses / suggestions?

Check your oil drain line and make sure its not backing up.

Where do I need to plumb it into?

Somewhere it won't drip on the exhaust manifold in right hand turns. A catch can would work. At higher RPMs and with the addition of boost it will probably carry a lot of oil still. Check out the "Definitive How Do I Catch Can" thread (or something like that). It is currently active so it should appear under new posts.

I really appreciate your help, both on this issue and my few others.

If I wanted to post some data logs and have some peeps give me input as to what to try/what's going on with my tune, where would I do so?

I had the same issue, breather=oil spraying on turbo manifold.

solved it by installing a dual port VTA catch can and plumbed both sides of valve cover ports into can and capped off intake manifold nipple.
