when i lift the clutch to engage to pull away either in first or reverse it judders just as its biting ive had a new valeo volvo clutch fitted but im running the standard clutch arm not soft pedal conversion on my f7p fitted in my 5 im just wondering if its cause its a stiffer clutch and the bite is either on or off when i had the volvo clutch fitted to my 5 with soft pedal it wasnt like that. what could be causing it :( thought it might be an engine mount maybe
I was convinced my valeo "volvo" clutch was slipping although it only juddered when pulling away. It turned out to be loose engine mounts
Tightened them up and no probs since. Definately worth checking them first.

thats what im thinking the rear one looks a bit suspect when i fitted itbut hard to tell when playing with it by hand was it your rear engine mount

give it complete death and get it warm. It might bed itself in.:D
had this on the wifes old 106 gti, it was the clutch fork, one of the legs had got bent so it was putting uneven pressure on one side of the release bearing. The fork is a different design to the R5 one so probably wont be that!
That wasn't much help was it?

Happens a lot on porches though mate, especially 924's!:D
Subaru's suffer from this. It's worse when cold. The cure's are - skimmed flywheel, 5k rpm launch.
Mine isn't too bad at the moment :agree:
Check you haven't got any fluids somehow leaking onto the flywheel or clutch face.

i did use some cooling system flush the other day some might have spilt out and gone in where the tdc sensor goes i wonder :crap:
Take the car for a run out, good bit of slippage now & then, and that should clean it all up.

make sure the rear engine mount is the right way round if you've removed it.
I know a clown that put it on the wrong way and it vibrated against the steering rack, the whole car juddered............... i am the clown !

Hey im no expert on these nor do i profess to known anything about them. Its all from memory from info i was told ages ago and it may even be the 948's? Any way my mates dad was well into them years ago, had a gold coloured thing. He was a club member and used to mumble on about clutch issues. It wasnt the the main arm part of the lever, but the forks that locate the release bearing. One would be a couple of mm out from the other. Other club members had the same issues. In the end if i remember correctly they had a batch of stainless arms made and the problem went away. I think (again i may be talking bollocks) the clutch was revised by porche (late 70's possibly?) and the cars never had that issue.

well i changed the rear engine mount yesterday and its alot better now hardly any judder think it just needs a good drive to bed in. the old mount was squashed by at least 1cm at an angle and it looked as though it was pulling away from the metal you can only fit these one way by the looks of it:eek:
