    Well this may sound odd but if my flywheel was loose what would it sound like. Cause I got this weird clankin sound coming from the bellhousing area. Im pretty sure thats were its coming from and occasionally it will make other farm animal noise's......

    Is it a constant clanking sound, even at idle? If so, climb underneath when it's idling and check it out. You could also remove the dust cover and see for yourself if it's loose. If it is loose enough to be making clanging noises, I wouldn't drive it another mile.

    The noise you are hearing is most likely something else. Maybe a rock or a bolt/nut got stuck up in there?

    Do you have any shifting problems? Could your tranni be going out?

    Thomas.

    Are you sure it's from the bellhousing area not the bottom end of the engine?
    Also is it just noise or do you feel anything wrong, like slipping or rocking, is it only when you're driving it or also at Idle?

    Is it a manual flywheel or a flexplate (automatic)? I've had a couple automatic flexplates crack and make some pretty loud rattling/clanking noises before.

    BAH! I bet its the flexplate bolts that connect the torque convertor to the flexplate. I'll put $ on it... my 400 used to loosen these bolts all the time. Take em out one at a time, and reinstall them with a little red locktite on them. /forums/images/graemlins/thumb.gif

    Just my .02

    Oops, stupid me. I even checked your profile and didnt even see the SM465 in the signature. Could be a problem in the pressure plate/throwout bearing maybe.

    SMART @SS! /forums/images/graemlins/thumb.gif k... well... forget what I said then! Does the noise go away if you depress the clutch?

    I did /forums/images/graemlins/grin.gif
    The first thing I thought of was the flexplate crack but I looked at his sig and found the 465.
