I'm working on a second engine, which came with my TR4A. It's a TR4 engine. I'm at the point of removing the cylinders, but they are really tight. Pounding away on a wood block hasn't worked, nor has using an aluminum block instead of the wood. I am reluctant to be more aggressive, as I don't want to risk cracking the block.
The problem is complicated by the fact that two pistons are seized in their cylinders. For that reason, tricks like making a puller won't work, at least not on those two cylinders. I'm thinking of pouring something into the coolant area, maybe phosphoric acid or a weak solution of muriatic acid, and letting it sit for a day. Or, something like that.
Any other, maybe less scary ideas? I don't care about the cylinders or pistons; obviously, they will have to be replaced.
