Right now I've got the head off my 2002. It's been off for over a week.
I had left it with #1 and #4 at TDC. The #2 and #3 cylinder walls felt silky smooth to the touch, but a slight gumminess on the driver's side.
I had cleaned everything out a little with brake cleaner and wiped it down, but there might have been some grit sitting around the rim of the pistons. I didn't intend on moving it at all until the next time the engine started, and planned on cleaning it better before that start-up.
Well, I couldn't resist putting my good BBS wheels and new tires on it once they arrived. But, sometime in the process of jacking the car to change them, the engine turned a little, not sure how many times.
I've now got it so that I can feel the #1 and #4 cylinder walls too. The #4 feels silky smooth, but the #1 cylinder has a rougher texture in places. I also feel some of the same in #2, and I'm not sure if it was there before.
It's not massive scoring, but its not that silky smooth. But it is an old car, with possibly 130K+ miles.
I'm not sure if I created this damage, or if it had been there. I've never felt a cylinder wall this rough before, but I've only had a few newer engines apart before.
My current plan is to blast some more brake cleaner around the pistons rims, scrape out the gunk with a feeler guage, or hopefully borrow a friend's air compressor, then go ahead and bolt it back together. If it runs OK a while, then I may just leave it. Hopefully the walls will smooth back down once the engine gets running.
If it goes pretty rough and can't pass a comp. test, then I gotta consider re-building the short block or replacing it... :(
