If it ain't one thing, it's another. Got my plug wire issue solved and went for a cruise only to have the rear main eat itself again - this time way worse than before. I thought I had this thing licked with no leaks after a few hundred miles and a bunch of dyno pulls. It had it idling in the garage most of the afternoon as I dinked with timing and such and it was dry as a bone.

It blew cruising at a low RPM and was fairly sudden when it happened. Limped it home in a giant cloud of smoke leaving a trail of expensive Driven oil behind me. Fortunately I was only a mile or so from home.

Not sure what I could be doing wrong. I can definitely see pieces of seal collected around the rear of the crank and I think I'm even seeing chunks of seal in the oil that's dripping down from the pan. I might leave this next pass to a professional.
