I posted this on Rennlist, inerested in any comments you might have....
All,
Had my clutch and flywheel changed last week at 63k miles, was still on the original Freudenberg and Clutch!
Stayed with DMF f/wheel, LUK item sourced OEM channel with official OPC clutch made by AP.
Car feels a lot more positive although I notice if I rev the engine under no load up to 3-4k revs I get a SLIGHT resonant vibration through the car which wasn't there before.
As far as I can see there are two possibilities, either the clutch/flywheel assembly is out of balance/true or something else has changed.
Wrench is going to check the clutch/flywheel next week with a dial gauge, he will also check the runout on the crank pulley. My question to you all is this - given that he didn't drop the engine, he did the job removing the gearbox only could it be possible that he has somehow strained the rear engine mounts when dropping the engine slightly to get to the top bolts? I am thinking that when everything is bolted back together this could then explain why more vibration is being transmitted through the car. we have tried all the obvious stuff like part of the engine touching the body etc..
Any ideas gratefully received, I stress that the vibration is SLIGHT, like a resonant "thrum" but it wasn't there before,
Thanks
Kevin.
