Mates C20NE has a diesel like tapping noise on tick over goes away at higher rev's (or at least gets frequent enough that you don't hear it!) after a long drive its not there either.

Any ideas def sounds like top end?

So far:

- We have changed the oil after a dose of engine flush
- Removed the power steering and alternator belts and started up, noise still there.
- Taken rover cover off and had a look at the cam, all seems ok

light goes off at a stupidly low pressure doesn't mean anything. two ways to do the lifter service, one is remove the head the other is to buy a tool from draper. about £11 and remove just the lifters one at a time

squash them in a vice to remove the old oil once you have refitted them they will only once fill up with oil and become very hard the dont drian out of oil everytime you start up and switch off they just fill up once to get the correct gap and thats it they are good untill the next time the head needs taking off or you get a tap.

the haynes manual tell you how to strip the them down to clean, but basically once lifter is out, remove the snap ring at the top, seperate and at the botton of the inner remove the wee cup. watch the ball bearing and spring, soak eveything in petrol /paraffin and then rebuild by reversing the above

No, that's incorrect. They have a sort of oil 'flow' through them, otherwise if they worked like you suggest they wouldn't get noisy even the oil pump started to fail, when we all know the tappets are the first to suffer.

However, a fair amount of oil does get trapped inside and it's not a bad idea to flush it out.

there is only one oil way per tappet the oil goes into that hole for the first time ever when they are new and the oil never comes back out of that hole
