was8v 0 Posted November 30, 2005 Has gone with change of oil, now just slightly clattery like all VWs.... My VR6 sounds like a Diesel with a "clattering" noise from the offside of the rocker cover. Its not coming from the chains side so I don't think its the tensioners. The noise increases in rythm with engine revs. I recently replaced the belt tensioner due to a whining bearing. Car is on 102k with full VAG service history (last at 100k, I changed the oil 1 month ago since the car has been stood for a few months). Its a clattering noise not unlike the noise worn or misadjusted tappets make. I checked the oil level, was just over the minimum, so I filled it to the max (is running 15 40 semi synth, topped up with 1 litre ish 10 40 semi synth). This quietened it slightly - does the VR prefer a slight overfill to properly lube the tappets?! I'm no engine genius so will prob be wrong. I'd just like to quieten it down!

Kevin Bacon 5 Posted November 30, 2005 Could just be worn tappets....... The breather box on the left side of the rocker cover tends to amplify the tappet noise slightly too, so it often sounds worse than it actually is... Quote Share this post Link to post Share on other sites
chrishill 0 Posted November 30, 2005 yeah tappets on mine rattle a fair bit until the engine revs over about 1500 - 2k then it quitens down, annoying but not fatal. Quote Share this post Link to post Share on other sites
was8v 0 Posted November 30, 2005 The noise is coming from that breather box! Ok so we think tappets then! It's not too bad now i've topped the oil level up, guess I'll have to keep a strict eye on the oil level. The car did smoke a little when accelerating after in gear coasting when running 10 40 oil (valve guides?) hence why i'm running 15 40 (cured the prob), so maybe a head rebuild is in order if anything gets any worse.

Kevin Bacon 5 Posted November 30, 2005 Sounds like it needs a head build, it's getting tired. Try 10W/50 oil in the meantime, older VRs seem to work really well with it. My oil consumption halved when making the switch to it. Quote Share this post Link to post Share on other sites
Stan 24v 0 Posted December 1, 2005 Ive got a similar problem mate, but mine is coming from the bottom end. Its going in this weekend for Andy Walker to have a look. Where in the NW are you? I can highly recommend Andy http://www.the-corrado.net/.archive/forum/viewto ... psi+tuning Quote Share this post Link to post Share on other sites
