I know you've heard this a thousand times before lol. But please read on...
Anywhoo.. Had the car for just over 2.5 years (brought it off Carl) and after 30k exactly the water pump decided it'd had enough and started chucking water out. So In my infinite wisdom I made my first mistake and thought how hard can it be to change right? lol. so anyway I went to pug and brought a new water pump and cam belt kit (they sent me with a 137 belt and tensioner etc). I took the old pump and belt off which looked like ECP parts and put the new stuff on. Timed it up using the 3 dowels and loosened the 6 bolts, tensioned the belt. Tightened the 6 bolts up. Turned it over by hand like 20 times with the spark plugs out to check for interference, put the dowels back in to double check and they went in ok put it back together and started it up. DOH! It now has a tapping. I pondered whether it could've been there before and I was just paranoid as it did have a very slight tap up close but no its definitely louder than any noise before, sounds like its coming from the inlet side of the cam covers from cylinder 2.
Now I'm not that naive so I am reasonably sure I've probably tapped and bent a valve but I'm just wondering how? I've got a RichW solid pulley so I know its not the infamous pulley slip. The holes seemed to line up OK so can the timing really go far enough out just with the cam adjustment? or have I just done something catastrophically wrong? and how come its only 1 valve? surely the tolerances between the valve and the pistons are near as dammit the same on all cylinders?
I've got no one else to blame but myself on this unfortunately, lmao...
Any help Greatly appreciated!
Cheers
