August 30, 20197 yr comment_719810 My 4AGE makes a noise that I think it's valvetrain related but I'm not sure. I recorded a video of it, after I give a little throttle, we can hear a "rrrrrrrrrrrrrr" sound. What do you think? Report
August 31, 20197 yr comment_719820 Rattles in the tappets, but otherwise it sounds fine... has it changed from what it was? Report
August 31, 20197 yr comment_719821 Tappets?......... You could check the cam bearing caps are fitted in sequence and torqued to spec. Have you shimmed the cams correctly? Do you know the history of the engine? The cam caps are supposedly specific to each individual head. Not swapped from another head? A mate had a similar noise which drove him insane...... Report
September 1, 20197 yr Author comment_719829 The noise has been increasing slowly on the last few months but this engine has not been touched for the last 3 or 4 years and I'm not sure that the cams were taken out. Edited September 1, 20197 yr by Viterbo Report
September 1, 20197 yr comment_719832 That doesn't sound too healthy..... how many k's on the engine? might be time for a head off and a trip to the machinist for a refresh. I'm sure its possible to adjust the cam shaft bucket shims in the car, but it mustn't be very much fun.... Report
September 1, 20197 yr Author comment_719834 It's the original engine of my GTi AE92 that shows around 180k kms on the cluster. That's what I'm suspecting, valve clearances are out which indicates shims or cam wear Report
