    Finally got around to split the clutch today. Car has been slipping above 4000 rpm which is a bit odd since the clutch was replaced some 3000 miles ago....
    Anyway, found a lot of goo in the groves of the clutch disc itself and while the pressureplate seems pretty ok, the flywheel also had a lot of greasy goo in various crevices.

    Already know what causes the problem even if I haven't taken everything apart yet, but thought it might be fun to see if the community has any ideas...

    So come on, make a guess.

    Leaking throw out bearing or rear main seal?

    Hopefully both of those things were replaced 3k miles ago with the clutch

    Not a F1 but a manual.

    Could be either. But the op says F1.

    The only thing that can cause goo on a clutch is oil. So another vote for rear main or release bearing. Or a long shot, too much grease on the plate splines getting thrown out.

    Or another long shot, I once had a major coolant leak (unrelated car) that found it's way into the bellhousing. The clutch did not like anti freeze.

    Yup, leaking throw out bearing it is!

    Have the receipt from the major done some 3000 miles ago (performed by Ferrari AD!), and ackording to the recipt they did change the trow out bearing and various other seals.

    I'm not too impressed!!!


    Anyway; Will go for HE upgraded parts this time.

    This might be a dumb question, but don't those oem parts that failed come with any sort of warranty? Did the work itself come with any pars and labor guarantee? Personally, I would be suspicious that they replaced them.

    3k miles in Ferrari world may be 7 years... curious what the time frame was if warranty could apply. Sounds like you're already aware of the improved Hill Engineering parts, good luck!

    The major (incl clutch), was performed in 2009, so I have very little hope to get anything from the AD.
    Maybe if it would have been 2-3 years ago, but 8..? Seems like a stretch...

    Anyway; New parts have been ordered... I'll keep ya'll updated.

    I had to change my clutch for the exact same reason as well, so that is why I guess what I did, haha.

    The way I see clutches now is either you drive a lot and use them up, or you dont drive a lot and the seals will make sure they fail with time and ruin the clutch, either way you lose the same $$$ so might as well drive them :)

    Just another reason to not let our cars be garage Queens. :)

    A possibility the wrong seals were used when the throw-out bearing was changed. One type for brake fluid and the other for synthetic hydraulic/ATF fluid.

    Hmm, you're right. That could be a possibility.
    However; Since the job was performed at a Ferrari AD one would expect a higher level of expertise, right?

    it could be bad seals on throw out bearing or install wrong, also you have to check the throw out shaft hub behind the throw out bearing there should be 3 small little o'ring behind the throw out bearing shaft housing sometime there not always replace they could be leaking.

    Still waiting for the rest to show up, so decided to take the rest of the clutch parts of the car.

    One can clearly see the benefit of using the right tool in this case...

    Also, there's a little goo where the shaft meets the throw out bearing...
    This turned out to be quite a mess taking apart as it was full of oil (red hydraulic fluid)...

    The measurements for the springs...
    I just don't understand what the WSM says. If I measure at those points recommended, my springs are waaay off. Not even close... Something is not right here... The springs were changed when the clutch was (3000 miles ago).

    Finally had the time to get around this again.
    Got quite a few new parts sent to me. Always exciting to get new parts - not so exciting paying for them though...
    Have gotten some questions regarding the thickness of a new clutch disc and I can verify 8,3mm as stated in the WSM.
