I noticed that oil smoke is comming out at idle, all the time, even after hours of driving. When driving, I cannot notice if there is smoke, but you cannot notice it at WOT, so I don't think its the turbos. Besides, turbos are kicking in when they should and not lagging or anything. The smoke is not normal warm up smoke, and my previous FD did not do that at idle after warming up.

What could be the problem? Thanks
