Blown turbo seal?
Hey guys i just recently bought an 08 335xi and i did cp-e downpipes and ae exhaust and a jb4 tuner and now i am getting an oil smell and alot of smoke out of my left tailpipe. it only happens when the car is warm and i am sitting at a stand still. smoke and smell goes away once there is any load on the car. I am thinking turbo seals but am not sure.
If it is the seals would i be better off going upgraded turbos or oem replacement? also has any one had any luck rebuilding them? any input will be greatly appreciated!
