Re: 4.2 V8 Timing belt replacement

I'm not agreeing with Pete. When You will keep distances (in belt's teeth) between characteristic points of every gear pulley, there's no possibility to change timing. Notice, that after tensioning a belt, there's no posiibility to change timing (telling differently: change position of crank, and each camshaft) by less, that ONE TOOTH distance. So any "milimetric" errors in timing are not possible at all.

But I agree in 100% with second part of Pete's post: Saving some pences on new bearings and tensioner isn't worth a grief, when You must pay for another engine in place of Yours - internally damaged due to timing crash...

So - JohnW - buy complete set for Your machine, and after that - take a great care with changing timing set yourself. In audi V8's it's really complicated. Turn attention, that You can tension the belt with two bearing: tensioner, and excentrical mounted roll bearing. Study properly, how tensioner works, and guess propelrly what for addidtional tensioner exists!
