Exhaust manifold heat shield? Could be any number of things? If it does it at standstill when revving the engine then the obvious thing to do is lift the lid and listen around while giving it some throttle.

Yer i have tried doing that and it seems to be purely a driving along thing. I will have it on the ramps on saturday anyhow for an oil leak so i will ask the mech to check for anything

I had this problem - turned out to be the bolt that secured the water pump was lose! If you rev you engine and watch the bolt/pump you can tell whether it's rattleing or not.

I know your pain man, the noise almost drove me insane as it only started at 2/3rpm. Oh and mine is a 16 Valve, I hope this helps  :smiley:

What exhaust have you got? Ive got a mate who has a stainless one on (cant remember make) and the baffles have started to go in it and make a rattle sort of noise at a certain revs.

had the same problem, it turned out to be the exhaust  heat shield which runs over the exhaust to the rear. The metal is very soft and can easily be bent out of shape and come in contact with the underside of the car, it was a bit fiddley to fix

You might want to check its not pinking as that could shorten the life of your engine a fair bit if left alone. What fuel are you running?
