So it looks like it’s the crank seals. Idk the best way to check the bottom one but the top is definitely toast

do the top one and retry.. maybe the bottom one is ok ??

looks like it is a simple O ring on the bottom but the head must come off .

Do I see metal shavings/chips in your picture?? If so, you better figure out what made that mess before doing anything else…

If you’re referring to the yellow flecks by where the mag plate bolts down it’s just random debris from the dirty rag I was using to clean out the grease in there. Not from the motor 👍🏻

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”
