the chain probably doesn't rattle, its the guides. its way cheaper to fix now, than later.
what is the cars mileage? at around 200 000km you should change the parts.
So I know this is a sign of the chain going out and needing to be replaced. My question is how long does it have until it goes out usually? What happens if it does snap on me? I heard that the whole engine is shot if that happens. Thanks in advance for help
I would take care of it sooner than later. I did mine a few months ago and its really not as difficult as it sounds. There's a couple great DIYs I followed:
Ahh I don't know man. Never owned a vr6, if I was you I'd take it really easy. I'm sure someone will chime in. However that timing chain atleast from what I've read, is not a quick job. Google timing chain replacement for your vr6 so atleast you have some sorta clue as to what's in store for you.
Just doing the upper guide and tensioner could probably be a one day job. Possibly a weekend depending on ability and the inevitable snags. Doing the whole shebang would take a lot longer as a lot has to be removed including transmission just to get to the bottom half.
You are a ticking time bomb for bending valves. You cannot change the upper tensioner completely without removing the lower timing cover. It would be even more retarded to not replace the lower stuff too......
Welcome to Corrado ownership 101. Cheap out or hold off on important items, it will cost you 3 fold vs doing it right one time.
