    I believe just pop them in your freezer, like 0 degrees F, put the block in the sun........ Then drop in, don't twist them!
    The 308 liners are not as tight as the 400i liners.
    (That's why we have "O" rings.)

    Note: The "O" rings don't come in aftermarket kits!
    Get the Real Ferrari gasket kit from Scott, you will get the "O" rings.

    (PS... I love your F car.)
    Good luck,
    Edwardo

    Hi Edwardo sounds like you have done a few liners.... once new seals are fitted do you bother to get the block pressure tested or once the liners are in theres no way they will leak ............. ps i love my F car to cheers

    Cheers back at you.

    Yes, my shop is going to pressure test the liners. But only to 1.0 Bar

    (And, yes, ha ha, I was in Liner Hell, like you now...... BTW,Ferrari Owners are freakin nutz....!
    Who else loves their cars this much?)

    Everybody keeps telling me to drop in a Northstar V8 and be done. NOT!


    Ciao Bella,
    Edwardo

    Mark,

    Cheers,
    edwardo

    unchartered waters for me .... i 'm having sleepless nights... if the liners are good and they don't leak why am i pulling them just to put new seals in there... what happens when i fit the new seals and they leak maybe i just rebore it and then press test it what do you reckon edwardo ....... cheers mate

    You have the motor apart. Youve pulled the heads off, and possibly disturbed a liner seal. Getting the liners out takes minutes, shouldnt take more than 20 minutes for the whole deal. If you dont clean down there and put in new seals, your risking a leak, and only a total tear down will fix it. So do you take the risk, after going through all this work, or spend 20 minutes and do the job correctly?

    Also, there tends to be corrosion built up on & around the liners, reducing coolant circulation. With the cylinders out, it can be readily removed. IIRC, Paul Colberg posted some classic pix of the amazing amount of corrosion he found in an engine, one cylinder had almost no water circulation on one side!

    It wasnt me, both my engines came apart easily, even my heads lifted off without fuss.
