Hey guys

Originally posted this in the Tuscan section but then thought its more of an engine/gearbox question.

My tuscan has developed a noise that comes from the transmission tunnel, the noise happens when the car is out of gear and my foot is not on the clutch pedal. I sounds like a scraping sound, however as soon as I put pressure on the pedel the noise stops but it gets worse if I hold the pedel just off the floor (around its biting point.

Could this be release bearing related or is it something more serious?

Cheers

Dave

From the sounds of it the clutch damper is worn out.

This is probably going to be more of an annoyance than anything.

When you put a clutch in, bear in mind the enemy of the clutch is grease. Having seen thousands of the things (used to be Man Trans & Clutch Engineer for a big OEM) I would grease the splines thoroughly and then wipe off all the grease so none is visible & the splines are tacky to the touch. Any more than that is way too much & it will wipe out the clutch damper in no time.

Sounds to me like the input shaft bearing (if the noise goes away when you depress the clutch, like you say). You should get a new gearbox and sell the old one to me (or donate it to the very good cause that is my car build).
