    Took the 348 out this evening for a short run to a local classic car meet. All well and good but when I got there and opened up the engine bay for people to admire I noticed a worrying amount of oil spatter around the gear box. I know it's due for a new clutch very soon and the flywheel needs repacking with grease but this was not looking good. The oil is quite thin and has a green-ish tinge.

    On the way home we stopped off to grab some takeaway food and was only stopped for a few minutes. My wife was driving and left the engine running to avoid the hot start problem we've been having. But in the few minutes the car was sat the temperature shot right up and it dumped a load of water from somewhere under the passenger side footwell (left side - it's a right hand drive car). I understand there is a pressure release valve or something in this area and after a good run it can lose a bit of water, but this was more than that.

    Drove the one mile home very carefully and the temperature dropped once we were moving. Once home I had a quick check and it sounded like only one of the radiator fans was running.

    First question is whether the two problems are related or merely coincidental. The second is whether anyone has any idea what could be the cause of the oil leak - I've attached some picture I took when I got home. I suspect the overheating may be down to a non-functional radiator fan but I will have to check further on this.

    I don't know about your oil/coolant leak(s), but your hot start problem could be due to one or both fuel pressure regulators failing (it's not always a flywheel grease issue).

    Easy to check. Just pull off the tiny black vaccum hose that goes to the back of each FPR (easy to see and reach when you open the engine bonnet).

    If there is fuel in your vaccum line there, then that FPR has failed.

    Also, your radiator fans can easily blow a fuse (especially if the fan connections have gotten wet). Check your fuses first. If not fuses, then temporarily short the relay for each to see if they turn on. If not a relay problem, clean the contacts on your thermo switch on top of your rightside radiator...and if that doesn't fix it then replace said switch (very, very easy to do).

    Thanks No Doubt - gives me somewhere to start at the weekend.

    Hmmm, that's not very helpful. Funny, but unhelpful ;) Perhaps I should have kept those 30 pieces of silver in my 348 contingency fund :D

    Peter,

    I had hot start problems with my 348. The dealer changes the 2 Fuel Regulators and it solved the problem.

    Hmmmm

    The pictures don't show that the cv boots are busted or that the clamp is loose. It looks to me that it's your rear cam cover gaskets, especially the one for the intake cam on the 5/8 bank, or left side of the engine looking in, is the culprit. The gaskets are pretty simple to change and you can change them with the engine in-stu. You are going to need to get new rear cam cover gaskets, and a good tube of gasket sealer. I like Hondabond HT, but some recommend using Permatex sealer. make sure you get the surface good and clean before you apply any sealer. You don't want your problem appearing again. To give you some more room to work with be sure to remove the air box. The whole job shouldn't cost you much, 30-50 quid or so, depending on how much they hit you for the gaskets. Be sure to change both of them.

    wash all the mess of with brake cleaner, then get the car securely lifted off the ground. Preferably get the car level to simulate normal driving, if you just lift the rear you might not see any rear cam gaskets leaks. Then run the engine in 2nd or 3rd gear. Looking into the engine bay, look for new oil/grease spray, if none yet then rev it up some by hand with the throttle linkage to build some wheel speed. I'm sure you'll find it. Now its so messy under there you may have multiple oil issues.

    The viscosity is too low to be CV grease.... :confused:

    LOL ;)!

    Thanks for all the suggestions folks! Must admit I went to bed last night feeling very depressed :(

    My nearest Ferrari specialist (Nick Cartwright) is only 13 miles away, so getting it over there, should it be necessary, won't be too difficult.

    I'll give the engine a good clean down at the weekend and do some very careful checking to see if I can find the source of the oil. I'm hoping its the rocker cover gaskets and nothing more serious - not that I have the facilities nor ability to change them myself, but at least it will mean a smaller bill!

    The burning question is, assuming I get the coolant problem sorted and check the oil levels, is it advisable to drive it? Not talking about a full-on blast around the back roads but more like a leisurely cruise up to see the Ferrari mechanic.

    If you drove it home, you can drive it to the mechanics....SLOW and Careful.

    Just pray my son that you won't need a "miracle" to repair.. are you certain that someone did not use the wrong weight oil in the gear box? Or is it just a bearing seal?

    I suggest checking the gearbox oil level, wiping the dipstick on a white cloth. Compare with the colour of the spilt oil. Do the same with the engine oil. One of the levels must be low if it is leaking so much. How much it is down by may give you some idea if you can safely make it to the garage with a top-up.

    I also had hot start problem.
    It was alternator problem, temporary installed new one and then replaced with rebuild - problem has gone

    Ok - quick update.

    Topped up the coolant - took about 5.5 litres. Removed all the relays and cleaned them with contact cleaner.

    Couldn't get the gearbox dipstick nut open so I couldn't do a direct comparison of the oil spatter. However, the engine oil is a nice golden colour, so it's not that. There is a rigid pipe coming out of the top of the gearbox that bends at 45 degrees to the left and then bends down the side of the cluch housing to point at the floor. There is a rubber cap on the end of this pipe and a lot of oil spatter on the pipe. I took the cap off the end and dabbed the a cloth inside and the oil was the same green-ish colour as the spatter around the engine. To me this indicates it's gearbox oil.

    I then gave the engine a good clean before starting it and getting it up to running temperature. No sign of any oil leakage or spattering from anywhere. Took it for a quick run around the block. Back on the drive both radiator fans working ok. During the warm-up the temperature got up to about 3/4 on the dial but quickly stabilised at the midpoint and stayed there.

    After the run there was still no sign of any spatter or oil leakage from anywhere. So at the moment I'm completely stumped as to what happened. I'm still planning on getting it into see the mechanic soon just for a health check if nothing else. The warranty I got on it when I bought it expires at the end of June so it would be good to get to the bottom of any problems before then.

    Cheers,

    Pete

    The pipe you describe sounds like the bleed pipe for the clutch slave cylinder. Have you checked your brake/clutch fluid level recently?

    Yep - all ok. One of the first things I checked.

    Hi Pete. I think the oil you found in the rubber cap has just found it's way in there from the general spatter.

    The dipstick, filler plug and drain are usually VERY tight for some reason. I certainly didn't overtighten mine but a year later they were tough to get out. A good socket set is needed, and removing the air filter box helps you get at the dipstick nut.
    You could really do with finding out if you have any gearbox oil left - it might not be leaking now only because it is below the level of the driveshaft seals.

    The T had the same hot start problem AFTER long drives. Turned out to be a overheated solenoid on starter. Ferrari installed a 'booster' from key to starter for $80, and never ever had a problem again.

    of course, fuel etc. as mentioned before can be an issue.

    Quick Update!

    Finally managed to get the car over to the mechanic. They're sure it's a drive shaft seal that's weeping and although it's making a bit of a mess, gearbox oil levels are good and it's still driveable. So panic over. :D

    It's going in to get sorted and have a good check-up and service in a couple of weeks.
