It starts after I've driven it for a while and the engine has warmed up. It sounds like metal on metal so I am wondering about fluids. The oil is full, don't know about the tranny fluid. Also wondering if the sound is coming from the water pump, fan. or some other moving part that might need lubricating. Any ideas?
Thanks,

Does the noise happen all the time once warm? Driving, stopping, speeding up, slowing down?
Where is the general area the noise is coming from?

I started it up today and as soon as I began to push the clutch pedal in, I heard the the high pitched squeal. I let off, it stopped. I pushed in, it started. ??

If the squeel changes when the TOB is accuated it gotta be the TOB. pull the cover on the bottom and look for a grease zert. It sounds like it's to late for grease though. lug | | | | | Joined: Dec 2004 Posts: 1,897 Shop Shark | | Shop Shark Joined: Dec 2004 Posts: 1,897 | It is possible that the act of disengaging the clutch could be pushing the crank shaft forward.

I would also suspect the front bearing in the transmission, pilot bushing, broken finger on the pressure plate. Don | | | | | Joined: Apr 2006 Posts: 46 New Guy | | New Guy Joined: Apr 2006 Posts: 46 | Thanks for the info and ideas. I want to check out the throw out bearing. Are there any pictures or diagrams online that would help me out?
