    That was just one of those things I let go.

    It wasn't bad enough to worry about.

    I know nothing about the 205 Blbut it sounds like a good idea.

    As long as it doesn't cause sludging it is probably something to look into.

    I'm a gasket guy.

    LOL
    Certainly possible.

    I don't think those plasticize compounds are any super secret or anything.

    I have replaced quite a few front and rear main seals. Never used epoxy of any kind during the repair.

    The front main seal is often times misdiagnosed. I have used speedi-sleeves on deeply worn cranks.
