I will remove the cylinder tomorrow and play around with the conrod, but this looks like there might be evidence for my theory. I haven't seen many heads & crowns, but having that much visible carbon build-up can't be good. Couldn't/wouldn't bits of it heat up and produce detonation?
As for the bore, I can still see the horizontal marks from when the sleeve was machined, though there's a bit of scuffing on the front part of the bore. Doesn't look too bad, does it? I'll see if I can't get measure the clearance tomorrow.
Now looking at the piston crown, I see an irregular circle in the center, which is actually a slightly raised area. I assume that's normal and not a sign of damage?
Anyway, do these pics say anything to you guys?
