It's fixed! I brought it back to my mechanic this week to have him look at the lifters and he noticed that the Upper Timing Chain Tensioner was only about half extended and had a nasty bend in the shaft! Amazes me that it failed after only about 3 years since I had a BRAND NEW OEM one put it when the timing chains were replaced, but regardless the car is running fine now.

So the oil didn't do the trick. I changed the oil and put in Mobil 1 10w 40 high mileage full synthetic. I did at least get to see if there was any metal shavings in the pan at that point and I only had a couple of small "crumb sized" plastic pieces which I'm guessing are from the timing chain guides. I replaced them at 94,000 miles so I don't think that's the issue. This sounds nothing like the way the chains did on my MK3 VR6 either. But anyway, it's sounding more like the lifters are the issue and I'm going to bring it into a VW mechanic this week. After doing the long screwdriver list

Thanks for the responses guys. I'm going to change the oil and drop the pan tomorrow for piece of mind to see if there is any metal accumulated in it. It doesn't sound like it's ready to blow any time soon and I will really kick myself if all I needed was a different oil. It might be wishful thinking to think that this is the whole problem, but it's worth a shot. I will really kick myself if it is as simple as that though. One quick question, do I really need to let the car sit overnight to let the oil pan sealant cure completely (I'm using the VW OEM stuff)? I Is that just overkill or can

Hi everyone,I'm idling really loud/knocking right now, and I'm getting worried about this. Probably taking it to a good VW mechanic ASAP but I just wanted to get some feedback here. It's a 02 12v VR6 with 141,800 miles on it.
