    Hi all
    My recently acquired 1995 F355 Spider, 6 speed manual, Rosso Corsa/Crema is due for an engine out this year. I am thinking March time frame so that he car is ready for the driving season...the car Capristo stage II and challenge grille, shields otherwise stock. I bought it knowing that it will need TLC and engine out this year. I already replaced the tires and will do the top likely next year. I listed the major item fixed by previous owners - I am the 7th I think but despite that the car came with a fair amount of receipts and it looks like it was not abused. Please do not crucify me but I omitted the PPI - the PO was very straightforward about everything and we made a deal which made both of us happy.

    I red a fair amount around here and learned some but there is of course a ton more to learn.

    I think some things to check are : shifter gasket, water pump, Shell Spiral S5 for tranny (per Sharik), shock actuators, rubber hoses, oil hoses, powers tearing reservoir cap/reservoir replacement?, rear main seal, valve covers (repaint), check radiator condition, sub-frame condition, etc.

    Car has some leak...

    Not having a PPI is not a big deal, as long as your ok accepting the possibilities of finding something.

    You'll probably find your lower cam belt drive bearings pn: 170787 are likely leaking. Replacing them requires resealing the pan and timing cover which should fix all your leaks anyway.
    While the pan is off, inspect the oil pump chain guide
    I'm sure you will get a lot more good advice here

    Are you taking it to a mechanic or doing the work yourself?

    I just completed my own F355 engine out and the car is at the dealer now for alignment, AC recharge, and to fix the ABS system which I don't have diagnostic tools for. Yelcab on the forum helped advise me as well as did the timing for the cams and helped me find a wire harness issue.

    1. Check your engine
    a. Identify sites of leaks & note them down
    b. Do a leak down test - This will let you know if your valve seals are good. You may find like me that you have 4-8% leakdown and one cylinder with 27%... and then you need to do a valvejob
    c. Blow smoke in the headers and look for leaks
    d. Plan the scope of your work

    Basic Major - everything checks out ok above
    - Order the ricambi kit, do the belt change, set valve timings (you will need custom measuring tools for this). Don't rely on hooking the belt back up to the same teeth on the cam gears... the belt stretches over time and you're putting a fresh / unstretched belt on... it will change your timings.
    - While doing this get your injectors cleaned. I used mrinjector.us Great service, fast, well priced, recommended.
    - Water pump comes with the ricambi kit. You'll be replacing it.

    Option: Valve job
    - Do this only if leak down is > 4% in cylinders
    - Here you're pulling off the heads, sending them to a machinist, and having either the valves cleaned or new valve guides installed. It's a complex job and may take a few weeks (once your machinist starts)

    Option: Clutch
    - Do this if your clutch is worn
    - It's an easy job on this car
    - If your flywheel is warped, now is the time to resurface it

    Option: Headers
    - If you see smoke coming out of your headers during testing, replace your headers with the engine out. It's far easier to do out than when the engine is in

    Option: Suspension
    - If your dampers are worn out, it's time to rebuild them.
    - Just a heads up that it took DeltaVee 5 months from time of suspension arrival to start my job. Got the suspension back 5.5 months after shipping. They're really hard to get a hold of, but the work is top notch. I don't have regrets, but many times thought I was never getting the coilovers back due to lack of communication.

    Other maintenance items you want to address while the engine is out.
    - CV Boots. inspect and replace as needed
    - Hoses (all of them - cooling, oil, AC, PS, Air) inspect and replace as needed. these cars are now 20+ years old. Any OE hoses should be replaced / rebuilt.
    - Spark Plug Wires - inspect and replace as needed
    - Alternator - don't replace / repair unless you've had issues
    - Sensors - replace the water temp sensors (relatively cheap, and easy to do when engine is out), replace others only as needed
    - Engine & Trans mounts - If they are collapsed, replace

    That's all I can think of right now. If you're sending it to a professional, they should know all of the above and will advise you to fix what you need to. If you're doing it yourself... you'll find things. Don't rush. These forums (and search) are your friend.

    Thanks a bunch - very helpful.
    Unfortunately I don't have the skills/space/tools or time to do the job myself. Maybe once I retire...

    That is incorrect from my understanding. Healthy racing engine cylinder leak down is 3-5%. I do believe heads are needed if closer to 20% from what I have read over the years on NA engines. I see that in car craft and a bizillion other magazines about building as well as my old 911 rebuild manuals. Example.

    I start saving my money at 10% leak down and do a valve job at 15% leak down. On the 355, once the problem begins, it goes down hill fast.

    Always love the belt stretch rant. 1) Belts don't stretch much. I have verified this be measuring old, high mileage (for a Ferrari, very old and very high mileage) belts. The difference between old and new belts accounted for about 1 degree of timing. Indistinguishable from timing changes due to belt tolerances. 2) Assuming the timing drift is due to belt stretch, replacing the belts will tends to restore timing to pre stretched values. 3) The need to retime the cams is more of an issue of confidence in whether the timing was correct at the previous belt change.

    LOL, as others have posted, this is nonsense. In any event, start with a compression test. If compression is good you're done. If not follow up with a leak down to determine where the problem is: valves, rings/liners, or head gasket.

    But mostly, if the car ran fine before you dropped the engine it will run fine after you change the belts.

    Very dependent on who does the work and what type valve guides you use to replace the old one. In my case the head work ran about $1000 to replace the guides and install and seat the valves. Parts associated with the job, guides, new valves, all the required gaskets and seals that were not otherwise necessary, ran about another $4000. Then there is labor to R&R the heads, throttle bodies, injectors, fuel rails, ...... Fortunately for me, the problem on my car came up while the major, which was part of the sale agreement, was being done and what it cost and what it cost me were every different. Let's just say the seller didn't want to lose the sale.

    Machinist work was $4k for valve guides. Including parts. Depends where you go and how fast you want it done.

    And ok, I'll admit, the 4% figure was very ambitious. Go with YelCab's recommendation.

    A cheap prevention would be replacing the fans. The original fans are not sealed and in time build up deposits that increase loading which blows fuses. If you don't notice this while driving, you might blow a radiator (or worse)

    I didn’t see anyone else mention this yet but they may have... while you are at it I recommend replacing the fuel pump or at least inspecting and if the pressure is good get something like the rebuild kit from Scuderia Rampante which will take all of an hour to apply to the pump and is well worth it. Easy enough to do with or without the engine in as it drops out of the bottom of the tank (be gentle with the torque on the nuts) but as it sits so low a weak pump failing to get adequate fuel up to the fuel intake manifold can masquerade as a number of things. If you go this route check the part number as even with the pre-5.2 cars Ferrari were inconsistent with their pump pn’s in the NAS cars.

    Yeah but you don't need the engine out to replace the fans. That's easy to do engine in, and you can buy them from Amazon.

    it looks from the receipts that the valve guides were similar to the above mentioned ~4K

    Completely unrelated to fans.
    It's part of the exhaust system. Specifically, the catalytic converter temperature warning system.

    I have a few other questions and figured it may be better to post them here than starting a new thread as my car description is here.

    So, I am adding a 348 steering wheel as stated in another thread and thinking about adding a Hill engineering dead pedal on both driver and passenger sides.
    Given that those need drilling and will somewhat change the factory look/OEM status (that is long gone with the exhaust though) do you guys think it is in any way negatively impacting the cars value?

    I think with those minor changes (especially the steering wheel which is easily swapped back) the car will look nicer and the food-well will look more "organized".
    Thanks in advance!
    Oh and If still have some energy left let me know what would be the best place to get flloor mats (possibly with the prancing horse)? Tried a few ones from older threads but with no luck.

    Fuel pumps can also be checked after the engine out. Since you do not know if they were done drop them and check for the rubber ooz. Cheap to fix before a contaminated system.
    Mine were original and were ok for 15 years

    During my last engine out, I noticed the air intake trunking deteriorating on both sides. On a spider, it's basically impossible to replace these with the engine still in. Also, the radiators have to be dropped.
