148 cyl sleeve

But the 148 IS a wet liner, right? I just don't want to be beating the tar out of it if the liner is pressed in.

I can't get anything much but a solid 3/4 bar up inside the piston because the crank & rod are in the way. She stuck when the crank was at dead center on the bottom so I can't rotate the crank to the side. I did remove the bearing shell so that gave me a little room to try to move the piston down. But I thought if I could push the piston up with the liner, I could take it to a shop & have the piston pressed down & out.

I hadn't thought about that but it should slightly expand the liner & with luck make the piston pop loose.
I'm going to hone out all the crud I can reach first so if it does start to move it won't go far before it should go easier. From the other pistons I see that the water didn't get past the rings, not like some real bad ones where the whole piston is corroded.
