Well, I think I'm back to square one.
"Guaranteed rebuildable" block showed up today.
I was concerned just what "guarenteed rebuildable" meant. And they specifically told me nothing was oversized, everything standard, and no machining required. Just new rings, bearings, seals, etc. Also was told this came out of a mx5100 that caught fire
Well, no evidence of fire, block still fully painted. That's where the good news stops.
Factory bore spec is 3.4252-3.4260....with a Max allowable limit of 3.4319. Well #1,2,4 are at the upper end of spec. 3.4260 plus or minus a few tenths. Bore #3 though is knocking on 3.4300. still under Max allowable....but still .004 heavy.
And the bores are scored up pretty good. And #2 and #3 show hot spots.
Pistons look like crap, no way I'd just re-ring them.
#2 and #3 rods look like they were pretty hot around wrist pin.
And crank , all though rod journals look good, is rusted bad. It's clear they showed little care in storing.
I'll let the pics speak for themselves.
Oh....and the cam....this wasn't out of a mx5100. The can is for a non-turbo engine where intake and exhaust lobes are both 1.335". Instead of exhaust lobe being 1.310
