silverline 0 Posted April 22, 2005 Report Share Posted April 22, 2005 my vr6 has covered 84k miles but it has noisey valve gear is it likely that the chain and sprockets are worn or would it be more likely to be worn tensioners? going by the mileage and the fact that the car has full vw service history i find it hard to believe chains etc would be worn!? not impossible tho. would just like other peoples opinion on the mattercheers.

mightyvr6 0 Posted April 22, 2005 Report Share Posted April 22, 2005 It's the tensioner blades that wear and the upper guide rail. The chains stretch too. The sprockets should be OK. Link to post Share on other sites
badboyV6 4 Posted April 22, 2005 Report Share Posted April 22, 2005 At that mileage id be very surprised if the chains were streched. If you mean that the top end is slightly rattly. More like a tappety noise, then the hydraulic cam followers are more than likely the fault- (its hard to say for sure without listening to it) Mine is a little bit tappety, especially from cold. Over time they dont charge up properly and then you get a larger tolerance between the camshaft and the top of the bucket tappet. It wont do any damage but i wanted to get mine changed to get it purring again.Genuine ones from VW are £17 each + VAT!! 12 needed....You can get a set though from Euro Car Parts/ GSF for around 80 quid. The other problem that can cause the top end to be noisy is worn valve guides but i find that very, very unlikely on an VR with 84k with FSH.....I have a set of genuine VW ones though which i might be parting with soon if my new VR doesnt need them.....

silverline 0 Posted April 23, 2005 Author Report Share Posted April 23, 2005 thanks for the feed back. its quite quiet when cold but when warmed up rather rattly. the guy at the garage said it was noisey at top end. best i get it investigated a bit more. it would be nice to have it running nice and quiet, is doing the tappets a long job?

badboyV6 4 Posted April 23, 2005 Report Share Posted April 23, 2005 not really a long job, i got quoted 200 quid for the job (parts and labour) Around 2 1/2 hours labour. If your fairly competent and can afford to have the car off the road for a little while its quite possible to do it yourself- i was going to do mine in the summer. YOu need a couple of VW tools to do the job though- such as the camshaft aligning tool.... Link to post Share on other sites
