eerrrr tapetty tap tap

[rralston]

Out for a blast earlier today, recently had the 12K service completed, and it was running very well, and it's got altogether a bit tapetty.

SP6 4.0 Litre Tuscan.

Sounds like one tappet, certainly high up in the engine.

Any ideas on what it is, or what I should do? I don't really fancy driving it too far in case I cause too much damage?

Cheers!

I should think people will start telling you it's the cam or a finger follower but I'd just get the shims checked again first if I were you.

I thought that - I've had it before, a shim disintegrated, and it was tapping louder than Fred Astair.

I'll give the garage a bell today!

Possibly also loose cam chain tensioner and chain tapping teh cam cover.

What's the correct way of checking and adjusting the chain tension? Would be useful to know as I now do most of my own servicing now.
