hey guys,

I heard this is a common problem with these engines.
My engine is still ticking after overhauling the complete cylinderhead. there were 2 faulty valves in there, we changed them and provided the head of new seals.

Before I bought it, another garage tried to solve the problem 2 months ago by changing the following parts:
- waterpump
- all in- and outlet valves (yeah, and still 2 got bent in one month time)
- cam followers
- distribution belt
- tensionroller

I'm out of solutions, maybe some one else had the similar problem ? I'm sure it's got nothing to do with the pistons or crankshaft or something like that..

it's about a GTi from 97', 62k on the clock.

As Mike said

If it has been a tapper, been rebuilt and still taps, either valves were bent when putting engine back together, or the valve guides are damaged.

You have to be very careful when refitting the head and timing the cams as the valves can hit each other resulting in bent valves.

I would imagine that either the guides and/or seats weren't checked properly or a couple of valves were bent slightly when timing the cams.

Well if he's so good and so experienced then why can't he figure it out?

If you're so sure it's nothing to do with the head then start looking elsewhere. The vacuum pump has been known to cause a tapping noise on occasions.

Or it could be the beginnings of a bottom end failure?
