No it was a LUK flywheel.
Does your flywheel always sound like that? Since having my parts fitted (clutch, flywheel, slave, clutch line) this is what happens:
Difference in idle sound when clutch is not pressed down when engine is cold. A ‘whirling’ sound can be heard which goes away when you press the clutch.
Sound gets progressively gets louder as the car is warmed up to the point where it develops into a sort of rattle. The sound will subside as the car cools.
Whenever you turn the engine off, the rattle occurs, quite loud. If you press the clutch the turn the car off, whatever it is, no longer rattles.
