Thanks All!
I understand about the Listeriods. Not like this model. Thanks.
Great suggestions. Red ATF is my first choice of penetrant, often thinned with a bit of diesel. (in some cultures red is good luck. Not a bad thing if you have a seized engine).
I've had the good luck (with red ATF) to free up a few engines, outboards and small diesels, and get them running, after a solvent rinse to get the chunks out. None seized quite as solid as this one.
Water is an interesting suggestion. I'll try it if it get the heads off. Don't want to put water in the bore and leave it for a week.
The Lister looks and feels like a good engine. Not a lightweight, high speed machine. It's been with the boat since new in 1976, across the Atlantic, through Panama, out to Hawaii, around Vancouver Island, and up and down the West Coast. It would be nice if it can be resurrected.
The top end looks pretty good under the valve covers. I can depress the valves that are not in play, and the push rods look good.
Patience plus penetrant, heat, and careful brute force? The boat is on the hard, with electricity available, so I'll try a heat gun, just to warm it up and thin the ATF.
I think next step is to pull the starter, which looks like it needs attention anyway, and try the pry bar on the ring gear. If I find no joy there, I'll pull the heads and see what I can see. With the heads off, I can try various combinations of solvents and heat. I'll stay away from acetone for now, for both short and long term health reasons. Maybe some 99% alcohol in the ATF?
It's nice to know that a thump with a hammer on a wood block on the piston is OK if I take the heads off.
If I need to buy a piston or a cylinder, how much do they cost?
Many Thanks! I have some things to try. The boat is 100 km from home, so it will probably be a week or so.
