Going to get more pics today. I haven't been able to stop by the shop myself so I'm relying on my mechanic for the pics.

What side of the engine do think the major thrust side is ? Firewall or radiator ?

reviving this thread because my valve seats are gone. How was the rehoning?

I think the thrust side is the radiator side since that's the rotation during combustion.

For a vehicle that doesn't see a lot of miles and the owner living close to the ocean, I wonder if ethanol was a good choice, ethanol being so hydrophilic.

The bores look like it's been sitting unused for a length of time and it'as had water in the oil.
It's rust.

Why do the piston tops look like that?
Have you scrubbed them?
