2002 Passat 1.8T, bought at 96K, now has 136K, and still runs strong.
Sooooooo, I had some idling issues last week, chugging, and missing, dieing at stoplights. Replaced the PCV Valve from O'reilly. The old one was pretty dirty, but not sure if it worked or not, but even after the new one went on, the problem persisted. Then I thought I'd check the plugs, as I have never replaced them.
Found the first hole had a bit of oil in it, second more, plus orange-ish oil on sides, third one poured out oil from the coil pack. Now, I am assuming that this problem is all connected. After finding that this is actually more common than I expected across all brands, I decided to prepare for the VC gasket, new coil packs, plugs, etc.
Here's the question: Should I replace the PCV system? I have seen kits form ECS I believe that are a kit to replace the "entire" PCV system. I ASSUME that the issue with the sucking/blowing sound while revving is because there is an issue with the PCV system, and thus the "overpressuer" has caused the gaskets to fail. Quite frankly, when I bought it, the dealer that I had to a once over noticed a small seal at the back of the engine was leaking. I just don't know if the PCV system replace would be necessary.
This is a daily driver, 7 minutes to work and home, and we use it from time to time. As I said, I bought it in 2010 with 96K, and it's taken us 8.5 years to put 40K on it. I would like to keep it for a kid, which was the original purpose, or trade it in. Ideas on the PCV, etc?
BTW, I am scheduling a timing belt (etc) replacement as well. I will more than likely do the VCG.
