    How much can the block be decked?

    I traced my coolant loss to a small nick in the block inbetween the coolant passage and the cylinder wall. I had a machinist measure it and it is less then half a thou or .00005 " Has anyone milled the top of their cylinders (block) and what would be a safe amount to avoid valve/piston interference.... say .002 if the block wasnt warped?

    .0005 IMO is not your problem
    tell us your mods... sounds like a blown head gasket from DETO
