I had the same problem that with the oil seeping under the cylinders (passenger side). From what I see on other posts, it's the PCV system. I have a 2002 passat V6 2.8L (apparently the later version). Some people recommend changing the hoses (which I will) and the "Y" suction pump. Problem is that I don't see that pump in my car. What I can see is the PCV valve or crank ventilation valve (as described by ECStuning.com). This valve cost $125 dollars, should I replace it with the hose? Again, I did not find the Y suction pump :banghead: Also, how many hoses should I replace?Thank you for your help:thumbup:
