Hi guys and gals,
I'd really appreciate some help with an annoying sound I have from my G60 motor. I have just completed a conversion in to my Mk1 Golf, this is my build thread if anyone is interested http://vwgolfmk1.org.uk/forum/index....llow-peril-g60
Now the sound was apparent from first start up https://www.youtube.com/watch?v=hlAm3if8bD8
I have traced it to the back of the engine. I have checked the idle screw on the throttle body and also for boost leaks but can't find anything. I've checked the belts for friction noise and the tensioners for dry bearings but everything is new and nothing coming from the belt side of the engine. I have checked the brake servo, no leaks there. I've also had the stethoscope out and nothing coming from the block or head.
The car is running perfectly, idling solid as a rock. I've checked the emissions and they are spot on and AFR is reading fine. As the revs increase the sound diminishes and almost disappears.
