if oil is coming from your turbo it's almost a given you'll see smoke coming from your muffler.pete1 said:If the hose internals are somewhat coated, unfortunately that's normal. In order to reduce emissions, everything that can burn gets re-routed into the intake system (kinda like a garbage disposal). In this case it's the oil vapor from the crankcase breather system (PCV, as mentioned above).
If you have oil actually dripping from the intake hoses (when you unclamp them), you've potentially got a problem. just to be sure, check your oil level. On the 1.8T, a little low is better than a little high.
I haven't seen many oil-in-the-intake posts that actually turned out to be oil from the turbo. In fact, i can't remember any posts like that at all.
