    For a moment I thought you had actually posted a real world situation were a Ferrari 355s engine had broke a rod due to a 3 quart over fill. But you didn't, because it has not happend.
    WTF has a vett got to do with a guy over filling a Ferrari 355 with 3 quarts? I understand you have to use a vett because you don't even own a Ferrari. And it seems you are not reading anything I have wrote.
    To reiterate so your slow mind can digest. I have never said that overfilling an engine with oil is a safe thing to do, and yes of course this could damage an engine. But lets get this right, you implyed that it could break a ROD with 3 quarts? That little write up you posted above did not mention "ROD". So why post it? Why try to move the goal posts as though you never said it?
    The guy comes on here saying his mates car was overfilled by 3 quarts. You come on and imply that this could lead to a cylinder bore filling with oil and breaking a "rod". So in a nut shell I called BS. Many 355 owners have overfilled, and you will not find one example of a rod breaking because of it.
    Show me an example of this senecio that has happend to a road going 355 with 3 quarts of oil, and I will gladly leave the forum never to be seen again. Now go search as well as go get your self a Ferrari to get reall world expereance of the marque.

    Well it's clear you do not understand the risk involved. You're just full of bs Mr wiseguy.

    Why don't you show us what happens when you overfill with 3 liters. If you're so convinced that it won't hurt, through in 3 quarts extra and come tell us the results.

    You're asking for examples. Do you honestly think that guys that own a Ferrari, full of themselves (of which you are one of the finest examples, overgrown teenager), that have overfilled and subsequently bent a rod (which is not the same as broken a rod BTW) would post this over a forum just to make them look like a total idiot ? LOL

    Yes dick head, I like many have already accidentally over filled our oil tanks. No bent rods.

    Wait I'm going to tell you how this works, so you know in advance what's going to happen.

    Your car has been sitting for a week or more. The oil has drained slowly to your pan. You measure your oil level when cold with a non running engine. You think : it's 3 quarts low. Untill now you think, I, selfrightous Ferrari-owner know what I'm doing. I'm filling it with 3 quarts.

    What you do not know, how could you with the brains of an ant, is that those 3 quarts are not gone. They are down below in the engine. Again, with your antbrain, you think hey, I did I fine job, I'm good. You start her up.

    What happens is the following : the scavenge stage of your oil pump starts pumping those 3 quarts right back to the reservoir. This is almost full. Now it gets overfilled. The scavenge pump is a positive displacement pump. The fluid in the reservoir gets pressurize.

    What you forgot Mr. Antbrain is that you have a tube going from the reservoir to your intake manifold (emissions equipent they call that Mr. Antbrain). The oil gets pushed all the way through that tube to your intake manifold.

    The pump won't have any difficulty in pushing it to the intake manifold because the cyls are sucking on it, so there is vacuum in the intake manifold. The oil ends up in the intake manifold and the liquid gets sucked in the cyl.

    If there is enough liquid in the cyl that the piston is trying to compress. It will hydrolock. BAMMM rod bent.

    Got it antbrain ?

    PS : if you are lucky Mr Antbrain and not enough ends up in the intake manifold it will foul sparkplugs, foul your sensors, burn oil etc.

    Your getting desperate now, and still no evidence of 355 rods breaking because of 3quarts of oil over.
    I understand fully what can be done to seals, Plugs , intakes ect, but it was you who bought up the subject of bent rods on a 355.
    When valve guides Seals go bad, oil is also drawn into the cylinders and gets burnt out of the exhaust. But everyone knows that. But a bent rod because of 3 quarts......Show me. I bet you have been searching every search engine you can find haven't you ;)

    Hi,
    I'm a newcomer here and I'm pleased to join the community. There is so much information on that forum !
    After reading this thread, I thought I should add my feedback.
    I bought my 355 2 weeks ago now. Drove it back home 1000km without any problem.
    Last week I decided to check the oil level and as I forgot about that dry sump system, I overfilled the tank by 2 liters.
    I immediately realized I did it wrong because the level reading was still below Min. and that didn't make sense to me.
    After starting the engine, the 1-4 light came on during 5min and went off after oil temp. was over 60°c.
    I then made some research on internet, found this thread and it scared me.
    I then called my Ferrari workshop. My mechanic told me to bring the car over and above all to drive it gently.
    He sucked out 2,5 liters out of the engine. He confirmed to me that it's way more serious to run that kind of engine with 3l. over the Max. than with 3 liters below the Min.
    He even told me that he once had a F430 with only 3 liters of oil left in the tank and the engine was not hurt! There was still enough oil pressure according to him.
    He confirmed to me that the risk (even with only 2 liters over the Max.) is to have too much pressure inside the engine block and to pop out a main seal, leading to a major oil leak, pressure drop and engine failure. It's kind of all or nothing.
    Mine held on well and nothing went ugly! The "1-4" light is always off now.
