I am three years into a project on my '91 Fed Elan - and I thought I was about 99% done Thanks to this incredible forum I have been able to pull the engine and put in a new clutch with all the associate things you renew - pumps, belts, hoses etc. I put in a new driven plate, pressure plate and thrust bearing, had the flywheel resurfaced and put the new bolts in. Finally everything is back in and it ran up fabulously. On the test drive I got about 300 yards before a tremendous rattle started up. The rattle/knocking sounds like something big and loose turning around. It varies with the speed of the engine and depressing the clutch decreases it momentarily and then it start up again. It is worse on the overrun after throttling up the engine. The only thing we can think of is the sleeve/bush in the crankshaft that the input shaft sits in. It wasn't touched in the rebuild project. After all this time I am not keen to chase something down that I don't have to, but it would seem as if I should take the transmission off (on its own this time) and explore. Any ideas or clues would be much appreciated. And thanks again for all that contribute to this invaluable source of knowledge.
