    Have you tried the two piece later model main seal???
    Some say it wont work, (too much slop in the machined surfaces) But I did it to a 54 235, and it stopped the leaks

    gotta love how rumors get started. "Those dont work" "Dont waste your money" "what a piece of junk" "that guys a jerk, he'll never sell that..."

    All it takes is one bad review from some one who dont know jack, did it wrong.

    I've got the same problem, keep us posted

    Don't know when they started putting seals on the rear main,but the early
    ones used NONE! Just a slinger ring on the crank and a corresponding
    groove in the block and main cap. The cap had a couple holes in the bottom
    of the groove to allow the oil to drain back into the pan. Putting any kind
    of packing in the early ones will assure a leak.

    i know they sell a "spray foam" type silicone for oil pans at parts stores. ill see if i can find the name for it....i think it was permatex or pyramex or whatever the RTV is called. i have seen it used on forklift motors and they dont even need the gasket.

    good luck. i am lukcy....mine doesnt leak from there,.....yet.
