Re: 164 Super 3.0 24V - With or Without Clutch Damper ?
It is SUPPOSED to work on the "upstroke", to limit the speed with which the clutch can be released. That being the case, it SHOULDN'T make the clutch heavier but on all my three 12 valve V6s it has, so I've binned it. I have suffered no ill effects in hundreds of thousands of miles driving.
I agree that Alfa won't have fitted it for "decoration" but on the other hand, I do think it was an afterthought - otherwise the pipes would have been shorter. As it is, you can throw it away and the hose from the end of the rigid pipe to the slave cylinder still reaches comfortably. My guess is that in final testing, they had a SLIGHT problem on SOME cars with clutch judder so they fitted it. As I've never driven a new 164 with new engine mounts and a genuine clutch, I don't know what difference it would have made but with an old 164 on "tired" engine mounts fitted with an aftermarket clutch AND having a slight oil leak from the rear crank oil seal, it makes absolutely no discernible difference whatsoever!
