24v cosworth top end rattle.. HELP
A friend of mine has a granada cosworth but it has a top end rattle, like its clattering when at high revs, drive around normally and its fine. Its been in storage for 7 years had oil and filter change. Like i said if you go over 4000 revs it starts to clatter, the higher revs the louder the clatter.. Anyone got any ideas as to what is causing it.. Just so you know, timing chain is fine, oil pump and oil light working as it should so were stumped.. Your help would be greatly appreciated, thanks mat
