Our Ralliart Colt has developed a noise coming from the gearbox/flywheel area. Kinda sounds like a big end bearing (if you've ever heard one before) or like a rattling kind of sound coming from the gearbox/clutch/flywheel area.

It only happens when the car is cold, and it goes away when you put your foot on the clutch.

The gearbox has some rollover noise, which is normal, but this a very noticeable rattling sound.

Any ideas?

Cheers.
