I know these self adjust, but they will reach the end of their adjustment one day and while I'm rebuilding my spare engine I thought I'd ask if these are just replaced outright (expensive?) or whether they can just be shimmed?
...or is it?

You cant shim these tappets.

I doubt they would reach their limit in the engine.

If you want you can regrind the valves back into their seats to get rid of any possible slack.

You don't! The clue's in the "self-adjusting" bit.

That was sarcasm Brian... I don't think anyone's that stupid.

Well, except Dazzy. ;)

When I had the head gasket done on my old E36 Compact 316i (I think that was M42?) it made quite loud tappy noise when I first got it back on cold starts. A good long motorway trip to get the presure up was the solution.
