    No tips but just gotta say that the person who invents a solution which will safely dissolve the white corrosion buildup between aluminum and steel parts will become a rich, rich man!

    Mumbles, is it too late to become a chemist?
    I have an ignition module for a 1990 Ford pickup
    that I can’t install, because the aluminum base
    distributer in the intake manifold is froze solid.
    Need some magic for that as well!
    I hired out snowplowing last winter because the
    old truck will only start if it’s 30 deg F. or warmer!
    Not of much use for much of the winter in MN!

    Prepare to be boarded!

    No, it’s never too late to study chemistry, especially for finding a solution to this problem.

    Around my area, where many motors have seen salt water use, sometimes the only way to free up stubborn parts is by bringing out the big gun, the trusty Mexican socket set!  It has to be used diligently though as it can cause more harm than good.

    Maybe I better button it up and at least hear it run once before I get the torch out!
    The stuck head just laughed at the little propane bottle torch.

    So, if you haven’t got the head off yet I’d suggest you do as George suggests and take the whole cylinder off with the head on it. With it off you can turn it over and use a 2 x 4 rounded up to fit the 2 3/8ths bore. Use the 2 x 4 as a punch to push the head off from the inside. A couple hits on one side then the other to try to bring the head off evenly. A couple of suggestions are not to try pulling on sparkplug threads. They will pull out. Take the sparkplugs off as the suction they make while installed makes it harder to remove the cylinder.

    I gave up on taking the head off for now. I finished putting the motor back together,
    and did about a 30 second test run on the stand. I didn’t hear any objectionable
    noises, but the real test will be when and if I get it on the boat!
