There is a good chance that the timing could be out (say i tooth on a cam). the car can run rough - with no valve damage resulting.
I know this as a fact, as I once changed the belt on my previous 164 and did not tension it correctly - the result was that I had rough running develop while I was driving it (had to live/drive with it for over 1 week). When I finally got the chance to check it out, I discovered that the timing was out/jumped by 1 tooth on a cam - re-adjusted it and tensioned it correctly, and it was a sweet as a nut.
So, the tollerance is not that strict for a minor amount
; but it will punish you for anything over
Also, the rear of each cam (gearbox end) has allignment marks (allign with the cam carrier/housing) - so you can allign without cam locking tool (takes a bit more time because you have to check constantly for any movement, but is possible)
Finally, plugs 'NGK PFR6B 3500 Platinum'
, I swear by then and never use anything else
..... and if anyone want to contradict me, I'll set my mum on them
