    When I started up this motor for the first time today, I found out
    the water jacket “cylinder cover” had a freeze crack in it.
    I have the cover off the motor now, but didn’t finish
    cleaning off the old gasket yet, or “thinking” about
    it’s design, before I called it a day.

    I presume the reason that the cover had a freeze crack
    was because the little bottom hole in the gasket was
    plugged up, but now, in looking at the photos,
    I’m confused of the whole design.
    It appears that water is on both sides of this cover gasket,
    and in order for the water to exit the motor, it has to travel
    through the holes in the gasket, then exit the hole in the top
    of the gasket. Is this how it works? If so, it seems a little
    goofy to me!

    first use a washer with rubber gasket on the bolt to repair the cover.
    I would think the water fills up the cyl’s first then enters the from the big hole on top to fill the cover. ???????????????
    you have 3 holes in the bottom of the gasket,

    Dave, your idea may work. After I get things cleaned up better I’ll come up
    with a plan.
