    Hi ian, all good advice from previous posts,one thing I would add is to check spigot bush in flywheel as I have found some worn over the years.If replacing bush it would need to be pre lubed either by soaking in engine oil overnight or you can put one finger over one end of bush,fill with oil then press oil down with another finger and you will see oil come out of outer walls of bush as material is porous.only other point I would make is to regularly check clutch cable at bell housing for freeplay as clearance decreases as clutch plate gets thinner to the point when there is no free play which means thrust bearing is acting on pressure plate thus reducing pressure plate load on clutch plate.just a couple of ideas... jim

    Could be you drive without finesse, operator error?
    New Valeo clutch should not present problems, i know this for a fact.

    I used to tow a trailer , two race Ducati bikes , mechanic and girlfriend plus supplies in my R8 to meetings in my R8.

    No clutch trouble.

    Thanks for the suggestions.
    I don't ride the clutch as i appreciate the nature of how it works.
    The clutch cable has freeplay when released.
    From all the comments my money is on gearbox oil leaking.

    I will start gearbox removal next weekend.

    Would be interesting to let us know. I have never had a clutch slip from oil leakage. My guess is any oil leaking in there would just be flung around and never make it to the friction faces. More likely something like Simon said, a poor quality clutch cover diaphragm, or maybe you just worn the plate down to the rivets already. Just to give you some background I have towed a tandem trailer with a R17 on it and forgot to release its brakes with my R12GL wagon and the clutch didn't complain at all. It has lasted for about 6 years with no problems and I don't drive like a lady either.
