    After getting on my soap box about trying to be a responsible owner in another post...I started to go back over "my list" of things that will be done when I do my upcoming engine major, which will be soon. I was wondering what things I might have forgotten to put on the list. I was wondering if there's a comprehensive checklist besides the standard 30K service stuff to include all the upgrades that can be done to imporve the original design a little and maybe prevent meltdowns.

    Here's what on my list so far and have begun the parts procuring process:
    1) Hill tensioner/bearings
    2) Timing Belt...not sure if brand matters? I've had good luck with Dayco belts (and degree wheel...thanks guys)
    3) Valve cover gasket set
    4) Front cover gasket
    5) Oil tensioner kit (ouch...the price is robbery but take a short cut and you'll be back in there and maybe with damage)
    6) Alternator tensioner bearing
    7) Alternator and AC belt
    8) Thermostat
    9) Cooling hose kit
    10) Cam seal kit
    11) Alternator rebuild (bearings, regulator and brushes)
    12) Water pump and bearing
    13) Center pulley bearings
    14) Spot weld belt guide
    15) Retourqe heads
    16) check valve clearances (no ticks what-so ever at the moment)

    Although my car leaks nothing (and I do mean nothing that I have found yet) I'll be replacing all the above so I have a good starting baseline. It's a 1991 348 TS with just 40K showing. Has some cometic blems from use but still a very nice car that I hope to make even better. I don't see the need to replace head gaskets as there are no signs of trouble ie smoke ect. If I see any signs (oil or water getting where it's not supposed to be) I'll add head gaskets to the list but I don't think it's common practice to change them yet....?

    Mark,

    I'm a big fan of Dave Helms' connector kit and this would be an easy step to include during the major. Details here:
    http://www.ferrarichat.com/forum/showthread.php?t=236795

    I would also check with Dave for his upgraded fuel and coolant hoses.

    Ricambi, a forum sponsor, has a comprehensive major service kit that includes the Hill tensioner bearings.
    http://www.ricambiamerica.com/product_info.php?cPath=40&products_id=162

    Do a search on gearbox threads from fatbillybob, ernie and marco - while the motor is out it is a perfect time to make sure the main and layshaft bearings are good and that the lock nuts are tight/staked properly. If they loosen up the gearbox can grenade and that can get expensive.

    Last but not least, no major is complete without the "Gothspeed Key" :D

    Ahh yes the key ;-) I'll add it on the bill...the number is growing exponentially fast, what's a little more LOL....right?

    How hard is it to check the tranny bearings and lock nut? Tranny dissassembly is not something I feel real comfortable with...I did some muncies back in my GM muscle car days but tranny work is not my "strong suit". There's too much going on in the Ferrari gearbox for me to be monkeying around in there. If no major disassembly is required I'm good with it but if it's deep, I'd feel better someone that knows what they doing in there deal with it. I've read some posts on the input shaft and am aware of the gernading problem. The proceedure I saw looked to be fairly involved...I don't want to have my head in the sand either if it should be addressed. It's had a new clutch put in it recently and no flywheel issues at the moment. I was hoping to maybe do this when the clutch replacment is due. It can all be done without dropping the engine, but agreed, it's MUCH easier to do when it's out. Maybe it's better if it goes on the list now and have a look at the clutch too while I'm in there.

    Your other links were very helpfull BTW. I want to do this job right and hopefully not be in there there again for awhile.

    As I haven't had to do it yet myself, maybe one of our resident gearbox experts can chime in. You don't have to get into the guts of the gearbox, just remove the left and right side covers for access to the main and layshaft bearings and remove the clutch pack and the cover below the thrust bearing.

    Since you will be draining the gearbox oil before removing the side covers it is also a good idea to run the oil through a strainer and make sure there aren't any large metal particles. A few metal slivers on the magnetic drain plug seems to be normal, but anything larger can be an indication of an internal problem.

    I just did Redline in my tranny. Old fluid didn't look bad ABSOLUTELY NO chunks of metal on the magnent only very small particles as you'd except to see from a healthy tranny. Doesn't look like impending doom but I'm sure the other with problems didn't see it coming either. Looking the other way can be a false out of sight out of mind sense of security. Not saying he unfortunate looked the other way as sometimes there IS no warning sign but I'd like to at learn from the experiences of others and avoid an expensive show stopper if there is an inherant "problem" with the tranny. The input shaft lockdown ring is a known weak link. What were they thinking...selling tranny parts is my guess LOL. I'm going to look over the posts again...Thanks for reminding me. It's better to do it all at once. MarkG

    I'm not a fan of opening the box for preventative gearbox maintenance aka tightening the lockrings. OTOH I know what to listen for. Usually there are warning signs long before destruction. But if you don't know I guess it is an easy enough thing to do.

    You may consider doing an alternator conversion kit to the higher amperage Nippondenso alternator (if your car has not already received the update). In any case, make sure the alternator is properly grounded. The alternator bearing shouldn't need replacement just for the sake of it... they rarely go bad. You can check it when the engine is out. The timing belt bearings from Hill I would definitely do.

    I don't know why you would want to re-torque the heads. If they've never been off the car, fiddling with them couldn't really help you any. Of course, if you were take the heads off, you'd need head gaskets, which I'm sure you know.

    Something very useful is, I think, a 4-gas analyzer test. For this you won't need parts. But, before the major, you should test the exhaust gases before the oxygen sensors while the oxygen sensors are disconnected and look at the numbers. There are ports for this on the exhaust manifolds. Then repeat the procedure again after the major to verify that the engine is running properly on its own (without the oxygen sensors).

    Check valve clearances is good. The valves on the 348/Mondial t require adjustment during the major.

    Also, there is an update to the way the cam seals seal up against the cams. This is a very important modification that addresses a common oil leakage problem. I am not able to explain it technically. But make sure your mechanic knows about it and how to do it. I saw it with my own eyes during my Mondial t major and also on the factory service bulletin sheet (which I am not currently able to locate).

    Hmm... what else. If you are running the original factory catalytic converters, I would definitely dispose of them in favor of a pair of aftermarket catalysts. Daniel at Ricambi America has Hyper-Flow catalysts very competitively priced. The factory catalysts on the 348 are garbage that will blow up eventually -- it's a question of when, not if. I apologize in advance if I'm telling you things you already know or have already addressed.

    I feel the same way...I would think you'd notice something (maybe not) but I would think new noises would present themselves and possibably the shifting would feel "different". I do believe in don't fix it if it 'aint broke and there's a fine line between prevenative and getting into something where you could cause problems for yourself.

    Some had mentioned checking the torque, I didn't know if it should be messed with or not. The CAT advice is well taken...didn't know they were subject to blowing. I've seen some folks mention busting out the factory CAT guts and making test pipes out of them ;-) I missed out on a real sweet deal a month ago on a set of new free flow cats for $250. The guy just wanted to get rid of them. I took too long to think about it (stupid me) and they were gone once I decided to go for them. My car shows 40K miles...my guess is CATS are due, not sure what the recomended service interval is.

    Good point on having the exhaust gas anayized...I was wondering what those bolts were for .-) I assumed it had to be something along those lines...Many thanks for the info. I'm getting lots of great info that I didn't consider. Collective thinking is great...this has been a great help to ensure I cover all the bases.

    Mark, I'm not an expert but when I was checking out the car you purchased, I didn't hear even a hint of whine from the tranny, and there was absolutely no movement of the shift lever when alternating between accelerating and decelerating. From other threads I learned these are two signs of impending failure and neither was present in your car.

    Still gotta get you the vids I took of my test drive. Maybe this weekend.
