Noise coming from cam belt cover

Postby Twincam.22 » Sun Mar 08, 2015 2:08 pm

On reving my 92 gt4 CS I can hear an unusual rattle when the revs are coming down. It's def coming from the cam belt cover area and it only happens when the revs are coming down, not when going up. It sounds like a tensioner or something rattling and quite worried about it. .

Didn't get a chance to whip off the cam belt cover yet but I suspect a tensioner bearing or something starting to go. .?

Any thoughts? Thanks

My guess? Your timing belt is starting to fall apart.

Pull the cover off and go from there. Anything outside of that is speculation.
