I Have a 2002 MC. 125000 km on it. I am getting a whining noise when in idle and when i try to accelerate. Now when i accelerate the engine will rev up but i am lacking the pick up and go that it usually has. It does this on all gears and sometimes will for no reason just over rev as if the gear slipped. It's a manual car.

In idle i hear kind of a chunking sound too, and like something is rattling.

Any ideas?

 

sounds like super charger gears have failed or coupler. Is it overheating ?Has the super charger oil ever been changed ? good luck

 

its your clutch...need a clutch...good luck

 

No super charger. Talked with a heavy duty mechanic friend and yeah he agrres with tom that it would most likley be the clutch and/or the rear seal since upon inspection we found alot of oil coming out.

 

Clutch is slipping/bad....the oil would do it, or just miles and age....if it has made some heat slipping, the flywheel is now toast too (the OEM dual mass flywheel is not resurface- able I think, not sure if it is on the basic cooper)!! Good luck!

 

Yeah thank you for the good wishes.

I am thinking since they got it apart eventually the flywheel is gonna go too. So might as well replace both. Thinking about getting some performance parts put in there.
