    My clutch is starting to stick. when I release the clutch, it sticks or gets caught; like there is something interfering with it. Doesn't matter much in 3-5 gear. but it makes it kindof jerky mostly releasing it in first and also in 2nd.
    the feel of it sticking is the same in all gears, it's just at higher speeds the jerkiness isn't as much because of the momentum, I guess.

    is there an easy adjustment, or better still, a solution with WD 40 at the right place?

    no warranty in my case; what causes it? what's involved in fixing it?

    Remove the clutch cable and lubing the @$$% out of it. I had the same problem with my GT4. WD40 did not work and finally (actually, very shortly) the cable broke.

    I replaced the clutch cable on my GT4 last summer. You should be able to do a search here and get the info you need. Its not too bad of a job. If the cable is starting to fray it may be binding up, possibly by the small pivot wheel just after it comes out the tube at the back of the car. Do you have a workshop manual? The procdure for the adjstment is there but is kinda hard to follow. let me know when you get to this point and I will help you if you need it. Good luck!

    Cheers!

    I'll look at the manual and see what's involved. But I'll probably have a local guy do it. I can replace an alternator, did the front brake pads in the car (but couldn't do the rear muyself); couldn't do the steel braided lines myself either) so I'm thinking this too is beyond my skill level. I can take most things apart, for me it's getting them back together right and operational which is the problem. thanks rick

    It could also be the throw out bearing carrier binding and dragging on the sleeve that it rides on.

    I think a significant part of the "clutch effort" was due to the binging and galling that the carrier was undergoing on the collar.

    Put a new clutch in, filed off the galled metal and lubed it with lubriplate and presto a 50% drop in clutch effort.

    How is the initial pedal effort??

    the clutch effor or feel was and is fine, depressing it and releasing. on the release it comes out alittle then gets stuck or binds, after the bind it releases the rest of the way normally.
    I've played around with it today, what I have to do in first and second is to release the clutch and wait till I get past the bind, before I give it any gas.
    normally I would both at the same time, at the clutch engages the transmission, but I can't now because I end up reving the engine with the car not in gear because of it sticking. This technique smooths it out somewhat, but it makes for much slower starts, and I've really got to pay attention.
    The other technique I've developed is that if I keep my heel on the floor and flex my foot back, rather than keeping the heel free, not touching the floor, it allows more control on the release of the clutch, and it's smoother.
    seems like a pain in the ass though, not as much fun to drive frankly. Not sure I'd be willing to put in a whole new clutch because of it, but if it's just the cable, that might be worth doing.

    you guys certain a well placed shot of WD 4 wouldn't solve this?

    by the way, like I didn't have enough mechanical things to worry about, I just picked up an 87 porsche 928 S4. getting it in a few days. I don't drive the ferrari or the other classics in the rain, so I hope to use it as a DD. Any of you guys have or drive one?

    Rick it was done as part of the rebuild.I tried to lube the cable first but that didn't fix the problem.

    drove the car to work this morning, only a mile or so. the clutch play was much better. very slight catching. I had worked the binding spot yesterday afternoon. just with the pedal with the engine off, kindof like massaging out a tension knot in your back. seemed to help quiet a bit. can pretty much do normal **** (let up clutch and give gas at the same time); car had been in the shop for 3 weeks for some carb and other work. maybe it's just the car's way of saying "drive me."
    will test it out later on a longer drive
