Need some help guy's before i crack up. Just lately there has been this really annoying rattling noise coming from the engine somewhere. At first it sounded like it was coming from under the rocker cover, so wiped that off, and there were a few rockers that were lose, so torqued them back up thinking job done.

Took her for a rip this morning and the rattle is still there. It sounds like something is lose, it's a very fine metal rattle, which made me check the exhaust housing and around, all seems tight, although i have not given it a proper going over yet.

I am worried as i don't know what this noise is, could it be a five min job or a serious problem, and not knowing means that driving it to check could also be bad.

Any suggestions would be great, is there anything else that it could be that anyone can think off, it's driving me crackers.

Cheers guys
