Been a few months since I posted on this thread. I originally had white smoke in the engine bay and driver's side exhaust. Appeared my front turbo was burning oil but has cleared up since I installed the OCC. I'm still blaming the turbo seal but the OCC has really helped and I don't recall seeing smoke since the OCC install. I'll find out for sure when my new turbo's go on and I remove the OCC.
