    When your F-car has sat for over a month is it best to crank the engine over until oil pressure is registered on the gauge then disarm the system and start engine? The sound of metal on metal for the few seconds at start-up makes me cringe!

    If you wait for oil pressure to register on the gauge you've done more harm than good. Just use your normal start procedure as if the car sat for a day.

    What do you do when your daily driver sits for awhile, do you use any special start-up technique......I think not!!

    When I take an engine apart (non-Ferrari) or do any kind of major service I always disable the ignition and let it crank until the oil pressure gauge starts to register before letting the engine fire up.

    With that said, if your car is just parked there should still be enough oil film on all interval parts to offer protection.

    But I would probably let it crank before start if your car were parked for like 6 month or more.

    I remove the sparking plugs, pull the coils, or fuel relays, THEN crank, then start it...

    Sooo you are turning the car over at a few hundred RPM's via the starter which takes for ever to build oil pressure vs starting it normal which takes just a few seconds for everything to prime up?


    Not 100% positive on Fcar's but seeing as they have always been technologically advanced compared to everything else I would assume they are like other modern engine designs meaning they are priority main oiling. Meaning the oil goes from the sump to the filter to the rod and main bearings first then to the valve train and then drains back down into the sump. So the most important bits (the rod and main bearings) get the oil pressure almost instantly, then the lifters/cups pump up which at least some models would be rollers basically what I'm getting at is there should be no damage to anything if you start it normally.

    Then again the best way to keep this from happening is to crank it up every few days to keep everything lubed.
