Just out of curiosity, what does the oil look like? Normally I try like hell not to take an engine down, but if the numbers you are posting are correct, you aren't going to be able to fix it without dismantling it. IMO. Some of the things posted here make a lot of sense, like bad hone job, screwed up guides, etc. I'm not thinking head gasket, but it could be. Nice if it was, 'cause it's an easy fix. As an after thought, it could even have a cracked head.
