no water was in the cylinder, just some condensation. didn't plug all the holes in the head, was sitting in a shed...

Not neccessarily........if the cyl. sat with water in it, then it could have rusted the rings and they will stick in the piston ring grooves. If that has happened, then it will have blow-by and not only have low compression, but blow the oil out of the valve cover.

yes. just get rid of the rust and sand around the barrel instead of up and down it. The rings will seat on the new section in about 100km.

wondering if anyone has tried this or what you think... have a block that sat for about half a year, 30,000 kms on it, a bit of surface rust developed on one cylinder wall, not enough to create any pitting. used some 2000 grit sandpaper to very carefully remove the rust, you can just barely still see the honing marks on the area i sanded, the honing marks are still fairly visible on all other areas of cylinder walls. put some oil on top of the cylinders and slowly turned it over. everything turns very smoothly. now, question is, is this going to work, will the rings still seal?? i'd appreciate any feedback, adrian
