    What you describe is definitely a sign of leaky crank seals. You can confirm a leaky top seal by pouring some TCW oil or fuel mix over it and turning the motor over. Any bubbles showing and you know it’s leaking. If the top one is gone, there’s a good chance the bottom one is to so both of them should be replaced at the same time.

    The parts arrive today and the puller tomorrow. I’ll have an idea by the end of the weekend whether this was the culprit. Hopefully this is the end of the gremlins 🤞🏻Thanks again guys for all the suggestions

    Ok quick update and a question. I got the powerhead off and I’m wondering if this hard o-ring carrier gets grease between it and the bearing or gets a sealing compound around its edge. Does anyone know?

    No sealing compound needed. Just grease the new O-ring that you put inside. Better to use a “Quad-Ring”

    The part # for the O-ring is 302540, and the part # for the carbon seal is 302538. The Quad-rings are available from many industrial suppliers based on size(McMaster-Carr) but offhand I don’t have the size.

    I believe it is this one, but do your own research.

    For some reason I couldn’t get the links to show correctly but if you search 305098 Quad O-ring on the site, you’ll see a discussion with the link for them at McMaster Carr. You want the 2nd link Buc shows…the Quattro Seals.
