Corrosion!

Got much of the carbon off the top with solvent and a toothbrush. There’s a ridge on the cylinders, but it’s smooth like the ridge was there before the overhaul and the honing smoothed it out. That’s okay.

Problem, there’s corrosion in the cylinders. It’s not that bad if you’re looking for a cheap way to get the car running. But worse than what I really want.

Cyl 1, chunk on side but it’s smooth. Should be okay.
Cyl 2&3, small speckle spots. Slight corrosion in the honing lines when you look at it right. Not a problem.
Cyl 4&5, none that I could see
Cyl 6, this one concerns me, there’s a big portion when the piston is bottom dead center. It’s rough to the fingers. It goes below the top of the piston so I’d need to pull the pistons at a minimum to steel wool smooth out the corrosion.

This engine has moved to backup status in the event existing engine can't be used (unlikely). I could pull the crank, but with the labor, I might as well buy a reconditioned crank from rockauto and get a set of bearings with it.

Cylinder6 - the worst one


Cylinder1 - odd spot
