i have recently converted my DM flywheel to a solid variety. mainly because it is susggested that this is the best ting to do when the DM breaks down. since i have had it back it had been making a jack hammer kind of noise, my mechanic says he is unsure as what it can be. had the usual parts replaced with the solid mass (clutch plate, bearing etc.) the noise is only there when the car is ideling, at lights etc but also when not in gear at slow speeds. it does go away when i apply the clutch though.
has this happened to any of you and what could be the cause??
cheers guys, Dave
