    Hey Joe,

    1985 QV liners installation procedure.
    1- clean liner o ring seat inside block.
    2- Lube o ring seat inside block with a thin film of engine oil.
    3- Carefully install new o ring onto liner. Note; don’t lube the o ring or the liner.
    4- push liner into block, don’t twist.
    5- Flip block upside- down. Note: On the head studs, use washers and pipe spacers to hold liners in place.
    6- Pour a glass of Enzo approved Diego-Red Wine. Good luck.

    Thank you - Perfect level of detail. One other question...I had my liners re-plated and they were marked for each cylinder and marked top and bottom so they could be re-installed in the same bore with the same orientation...Needless to say, even though i asked for Millennium to preserve the markings, they were sent back without them - So I will install them wherever and I can't tell if there is a top or bottom (they look symmetrical) - Is this a problem? Am I missing anything? Again, thanks for your help on this - it appears from the threads I've read that you may have done this several times - Joe

    Hey Joe ,?

    I would use my bore gauge to place the liners in order of loosest to tightest. then, I would use my calipers on each piston to do the same.
    Essentially,, matching all specifications for piston/liner clearance.

    good luck.

    Question for the group.
    If you purchased new cylinder liners, what would you use? Steel or try and resurface the old liners?
    Would you re-bored the liners with a torque plate to insure proper fit? I worry that worn liners may 'egg' shape even if replated.
    Thoughts?

    Not sure if this helps (and I wouldn't pretend to know the situation for every used liner) but mine were checked for concentricity and lack of taper by the company that did the re-plating - all checked out perfect. In addition, when you have them re-plated, they can build the plating up to create a perfect piston to wall clearance
