Welcome to the forum!Hello Guys!
I have a 2002 Audi A3 ASZ PDTDI with a GTB2260VK turbo, FMIC, AL injectors and an open exhaust.
It currently has 267k km-s, and produces 220whp on 2.2 bar of boost. This is a safe remap done by a professional for me, bc I didn't have the money to risk running more boost and having the engine go boom boom.
I love it to bits, we have done 17k km-s together, and it hasn't skipped a beat since. I love how it sounds, drives and feels. And I also love that here on the forum You guys have answers for every question.
My question is, yesterday I took off the intercooler piping at the top of the engine, and there was some oil buildup. By some, I mean I was able to clean it up with a rag. Note that it's at the very top of the engine, above the turbo and everything. I know for a fact that the turbo's oil return line leaks some oil, and the car needs about 0.7 litres of refilling of oil per 8000 km. I'm looking forward to getting it remapped to 2.4 bar, but before that, I need the car to be in good condition. Should I be worried about the turbo, or not? I haven't looked at the intercooler itself yet.
It leaks oil somewhere, I don't exactly know where, maybe from the valve cover gasket.
Should I get the turbo fixed before I remap, or am I safe to do so?
Thank you for your replies in advance,
I don’t know anything about your engine but if it’s anything like out North American TDI’s of that time frame then I think a light coating of oil inside the intake piping is pretty normal, as the turbo oil seals can’t seal 100%. But you may want to start a separate thread with your question, to get opinions from the guys that actually know what they are talking about.
After all, I only hang out here to learn, I don’t know much yet.
