I live in Tn pull to Phoenix 2 times a year. I would like this for tunning.

I agree that loose rotor screws are bad, but why would the rotor want to consistently advance. My guess is it would bounce around and tend to retard the timing.

Dan caught alot of slack from the video he had with thr gopro mounted in the bilge, showing smoke coming out of the breathers. At the time of the video, he also had a moisture issue with his oil, and had a significant amount of milkshake going on. I believe what was coming out of the valve covers in that video, was actually steam, and not oil smoke.

Irregardless, those engines consumed a bunch of oil, and were due for rebuilds.

Im no expert on failure analysis, his rotor screws had came loose from failed lock washers on one engine. The rotor screws were so loose, it allowed the rotor locating tab, to even become disengaged from the distributor.

My initial thoughts, were the timing became excessively retarded while he was running wfo for a long stretch during his last boating outing, piston got extremely hot, and began scuffing the bore, and tuliping an exhaust valve.

The other engine, which had the same tune, had no damage, still showed good on the compression test and fair on the leakdown. Engine with rotor coming loose, had damaged piston, and tuliped exhaust valve.

Thats just my theory, and it could be way off.

She was definately getting hot. Was there any other loose hardware on that motor?

Nah. Weird thing was the concave lock washers, literally rusted and disintegrated. Other engines washers look brand new. Both replaced at same time .

That would be my diagnosis also.

Don't forget the Loctite on the rotor screws!! Lol! We thought the motor tossed a rod when this happened. When the rotor let loose it hit the cap so hard it spun the distributer!
