When VCG goes, you can start to get boost pressure into the crankcase due to the upper small round intake runners going through valve cover. You would get oil coming out of seals at either front of rear of engine. Hopefully, you don't need to overhaul the engine. Good luck.
Thank you for the reply cuda, I have seen my boost hose from the turbo to the intake is leaking oil, I have a ATM kit for it I need to install, so maybe the ccv has caused this? Now it is coming out the rear? Trust me I don't want to rebuild it yet :/, it is throwing a code for the sensor before the Cat not getting signal, however I will see if that's why it is doing it. I would really hope just one of the injectors is going bad. However, I don't see any oil coming from the VCG, so it may not be that unless it will just leak boost and not spray any oil out the gasket but that would be crazy. Anyway I will have to diagnose it some more and get back to y'all with my findings. Thank you
The vcg has an inner gasket for where the intake runners pass through. You wouldn't be able to see that one leaking.
