[quote="911hillclimber"]Took the engine out this morning in a lazy 2.75 hours, usual snags and tribulations. Seems to come out differently every time, this is the 20th time it's been out...
Reason for the removal was is trace the vibration at 3000 rpm which on the last short run was getting much worse. When i pressed the clutch pedal in the vibration cleared, came back at 3K etc.
Could be the clutch 'system' but decided to pull the lot out in case it might be something else and have a good mooch round.
Well, it is the clutch but not what happened to hot66 but the diaphragm spring rubbing on the release fork body. Never had this before ever and this car has had about 15 clutches.
I guess it could be the way I have adjusted it, but it has the stock 3.2 helper system and that has never been an issue before. New cable etc about 2K miles ago.
Actual clutch is fine so is the release bearing, quiet and very smooth and only just loose on the diaphragm fingers.
Thus, the spring must have been 'just' touching the fork body hence the vibration, but this surely would have been throughout the rev range, but at higher (than 3K) maybe the vibs just became a single noise?
Anyway, I will have to fit a new clutch assy now, can put the old in and keep my spanners crossed all will be well.
If anyone can suggest another reason for the vibs at 3K please please post!

Hmm that's odd the fingers are touching the pivot bosses which are fixed, is there some kind of crankshaft end float issue here?
I was really surprised at how good the sound actually is. And I was worried I might not be able to get anything FM as it came from the States. But it works really well for Radio 5 Live and stuff on FM is really good reception.
