It took nearly a week for all the oil to drain out of the cylinders.

My friend got the head off and I got it back from the machine shop today. It needed 4 exhaust valves and 8 valve guides. And um, a bunch of money. One valve was visibly burned; I don't know yet why the other three were rejected. Maybe my mechanic friend will see what's wrong with them.

I cleaned a good 1/16" inch or more of baked-on carbon from two piston tops. The other two pistons will have to wait for the weekend. No cleaners I tried did much good but a Dremel rotating bristle brush thing was good. Keep a vacuum hose end right there to grab all flying dust, and suck it out of the gap between piston and cylinder wall often too.

There's a crack in the exhaust manifold that my friend plans to weld up. I pay him for his time on weekends or evenings.
