a machinist shop, unknown history. Cold compression is:
300
110 (add oil: 190)
210 (add oil: 210)
300
285
Chain stretch via notch method: 5 degrees.
I believe this lump has good enough bones to fix up rather than start over.
I started replacing the chain but let it jump, so I can't do any more compression or leak down testing. Head's coming off, we'll be looking at bores soon.

If you have many more questions you are probably better off starting a new thread - but - I thought it was worth mentioning that you can still do a leak down test with chain off => it is indeed quite a good exercise as you can put the piston at different positions with the valves closed and get a much better idea of bore wear (if any).
