    The rear pumpkin, at the bottom, there is a small 1x3 or so plate with holes in it. After a drive and then parting it for a few hours about a quarter size leak develops of light blue fluid. Today, I kind of caught it in the act, and its coming right through one of the holes in this plate? How can I address this. Thanks.

    Other then this, a very very minor oil leak further to the front, likely a cam seal that I can address at the next major, but only a few specs even ifs been setting a week.

    This is a 90 348TS BTW.

    Either your throwout bearing/slave body is leaking or the triple shaft seals are leaking. :) Easy job to fix.

    Hey Pap, thanks. PO had some tranny work done just a few months ago. I haven't messed with the tranny before other then linkage, any details on how I can fix this myself? Also, how can I tell where the fluid is low, and will I need to add more after the fix? Would you fix this ASAP? I'm concerned about the fluid level over time, this its only a few drops after each good run.

    No worries Tex ;)

    I have a RHD so my clutch reservoir is under the front bonnet on the right hand side, Im assuming yours is a LHD so your should be on the left hand side of the car under your trunk, you can access it my removing the snap on square inspection panel and removing the plastic cap. I myself would fix this as soon as you can, its been a while since I looked in my 348 bible but i'm sure that your brake fluid is fed from the same reservior so make sure you go out check the fluid level straight away either way as you don't want air to be drawn into any of those circuits as it absorbs more moisture and is compressable unlike brake fluid, trust me a spongy clutch and brake pedal at speed is not a good thing ;)

    Hello Pap, you say its an easy fix, can you send me instructions and how to determine if its the salve body or seal now that I know what these look like, but most importantly, easiest way to get to them and replace them as necessary. How many hours do you think this job takes?

    I'm going to attempt it myself I think. Still looking into doing the major myself next year also unless I find a good shop in the southwest that doesn’t over charge for service like most dealers, but I think the experience itself is the main reason for going at it myself. Saw a cool way FBB did an engine out without a lift! One other nice thing, it looks like a clutch change is easier on this car then most, so not everything is harder or more labor hours just because its Ferrari.

    Here are some links that can help you. Once you get the pumpkin off, it should be easy to diagnose the leak mate. It took me around 30mins to take to the bottom muffler off and remove the pumpkin. Then go from there. Trust me, not hard. ;)

    PAP, what model year is your car?
    I've got a 1990 ts, just wondering if I have to remove the rear bumber to get the clutch out.??
    Or just the muffle. Probably don't need to but I'm going to check the flywheel, just because I hear it rattle from time to time.
    thanks,

    One of my friends here in town has either a 90 or 91 ts and we did not have to remove the bumper. Removing the pumpkin was a relatively easy one-person job, reinstalling was much easier using a helper!

    How much are the seals and slave body? I'd like to order what is needed first, then take it apart and hope it all goes back together again :D I don't need any special tools? Is it hard to get the old seals off? I'm guessing just to fix the leak, the clutch doesn't need to be pulled from the housing/cover? Sorry, I'm a newb working on rear engine manual trannys. Tranny was just put to ether a few months ago by the PO so I’d like to make sure all is tight with no leaks, even though it is minor.

    I don't have cats and have a tubi exhaust, looks like enough room without even removing that!

    You do not have to remove the rear bar. As Greg just mentioned. Im not sure how much the triple shaft seals cost, but the slave body can be found at www.ricambiamerica.com. Tell Daniel we sent ya. ;) He has the stock OEM and the Hill Engineering version slave body. Stock is around US$450. The Hill Engineering slave body is better Im sure. Costs more too. You dont need any special tools for the job. You dont even need to jack the car up off the ground. The triple seals pick out easy and to put them back on, soak them hot water in a cup to soften them up a little to help re-install. Not overly hard to do. You do not have to remove the clutch assembly from the pumpkin. That stays in there. Easy steps---

    1. Remove bottom muffler.

    2. Remove all 6 pumpkin nuts(2 starter motor bolts) and clutch/slave body pipe on LH side of pumpkin.

    3. With all the nuts/bolts are removed, get a 2nd person to press the clutch pedal down once or twice to 'pop' off the pumpkin from the gearbox studs. You keep an eye on whats going on with the pumpkin while the pedal is depressed. You may still need to pry the pumpkin off carefully using 2 screwdrivers either side.Thats what I had to do with mine to remove.

    4. With the pumpkin removed, inspect where the leak is coming from and go from there.

    I honestly think you should wait till you get it all apart before you order anything mate. Its only a 30-40min job to get apart. When its apart and you know what you need, then order the parts, wait a few days, then re-assemble and bleed. You cant mess it up. If I was there, id happily do the job with you and give you a helping hand through it. Im the only guy in town with a Ferrari. I wish there were more, so that I can help work on them. I love it. :)

    Hey Pap, your a great help! Thanks man. Wish you did live nearby! This forum is the main reason I bought this car, and why I would even consider an older F-car being as far from a service place as I am in the first place. I don’t know why, but out of the last few V8 models, maybe except the current 430, I just find this style and driving feel so much more striking!

    I just figured I might want to change both while I'm there, but if it’s just the seals, I'll tackle that and save a few bucks. I’ve ordered from Ricambi before, so I’ll talk to him again and get a small set of other items I need anyhow that I have been putting off a few weeks due to work. and other commitments.

    I know what you mean about being the only Ferrari in the area. I’m building up some confidence with this car and by this time next year, may even do the major service, though not 100% sure on going that far yet as I’ll have a lot of parts to pack if all doesn’t go right, lol. Trying to build up on the performance also and pickup where the PO left off in that regard, but cleaning it up A LOT MORE in the process as well. Surprised there hasn’t been more done in the aftermarket.

    So it will be really obvious when its open as where to its leaking? Also when its all done, do I need a bleeding kit or something? Please explain any details after its all buttoned back up. Also, you recommend doing it right away, so I will, but what are the negative side effects of a small leak like this?

    Hopefully you will see the leak straight up and you will know what to replace. When you re-assemble, when its all back together. Make sure the brake/clutch fluid resivior is full, then get a 2nd person to start the car, depress the clutch pedal and you crack the bleeder nipple for the clutch on the LH side of the pumpkin. 2 man job. Or you can buy the 1 man mighty-pump or whatever its called to do the job yourself. Whatever you want to do mate. I had a mate there to pump the pedal for me. Took around 2 mins, 5 'pump&cracks' and all the air was out. The downside for leaving this leak, is that one day the seals may blow out and you will have no clutch. Also the fluid leaking can be thrown around the pumpkin and all over the clutch plates and which will eventually destroy them. Dont leave it too late. :)

    thanks again pap, going to attempt the fix next weekend. Will look you up if I run into any trouble. In the meantime, have a few other things I'm fixing on it, and hope to get a little drive time in today :D
