hi, im new to the e30 sceen and this website

ive just bought a 325 cabby which is really clean but does tap a little from the top end. i was woundering if anyone on here has had this before? Im guessing that it just the tappits? but what i would like to know is what are they like to adjust to solve this?
any help would be great.

Most probably is tappets, most of them do it!

There are a few thread around about adjusting them from the manufactures specs, unless it is excessively noisy its nothing to worry about.

Might be worth checking them anyway.

If you tighten them too much it wrecks your idle.

Apparantly a lot of tapping you hear in the car comes
at you thru the steering column. You should be able to test
that by putting your hand over the steering wheel centre,
I tried it but I was being deafened by the funk at that time.

I also have a theory that the adjusters get little flats worn on them
which makes them almost impossible to adjust after a while.

Anyone know if dealers just sell the eccentric adjusters?

I think I remember someone saying something about the exhaust manifold gasket aswell, if it's a bit knackered it can add to the noise... I could be completley wrong about hearing it, it might just be from one of my strange dreams :lol:

you're right dude- a broken stud or leak from the manifold can exibit itself as a "ticking" which gets worse as car gets warmer
