Ok will try and keep this short as possible... MK 3 VR6 1993 The cars been running fine and had a head rebuild after the headgasket went-no problems. which was about 12 months ago. Recently the car had part of the top cam chain tension break off and (about an inch) which fluttered around with the cam chains. Cutting a long story short the car was put into a garage and had both new cam chains, all new tensioners,adjusters and new oil pump changed all at the same time.(all new from vw) Obviously the garage was incompetent as the car now has a dreadful sound which i can only call a cross between
