vwgti 0 Posted October 10, 2010 Just Rebuilt my VR with new chain guides and tensoners,cam followers, ported the head and oil pump, it starts up fine but when the oil temp hits 74+ C degrees the engine becomes rattly, if I rev it to about 3000RPM or so the rattly sound disappears! When i drops to idle the rattly noise appears again! Sound like the cam followers but they are new! Any help on this appreciated as i am really sad after spending all the dosh and time on it!

Kevin Bacon 5 Posted October 10, 2010 New followers can take a while to completely drain of air. I think there is a procedure for bedding them in somewhere, but they will eventually quieten down. Quote Share this post Link to post Share on other sites
vwgti 0 Posted October 11, 2010 I really hope so, as I have been running a AAA engine ever since I got my corrado and only late last year I manage to find this ABV engine! Decided to renew all gasket,Port head etc. But why its quiet on start up :scratch: then becomes rattly when the oil warm up!!! Will put back my bumper lights etc and take it for a drive I guess...

jamiehamy 0 Posted October 11, 2010 I've posted with this kind of issue before, i find my car gets 'chattery' when warm. Sounds just fine cold. It's not a loud noise, just a kind of cyclical chattering that is similar to tappets, but about 1/4 as loud and not as destructive sounding. Will try a thicker oil next service ( due soon).
