We are having fun now - third party image

I did find the rear main seal issue - spring that holds it tight around the crank was broken - third party image

I am happy with what I've found, generally - the bearings look like new - - I'm thinking about things, but I'm inclined to reuse them - they are standard bearings - I am up against lack of tools now, I don't have a set of micrometers that can check the crank and rod journals - I'll have to either borrow or haul the crank somewhere - third party image

I don't see any sign of the block cracking at the lower end of the web - rod bearings look just as good as the mains, I haven't examined the pistons/wrist pins closely yet, but it seem likely that I can buy a set of rings and get back in business -
Someone mentioned pulling the sleeves and resealing - the sleeves are sealed to the block with o-rings? o-rings of the sort that are available at a hardware store? I'm not opposed to doing that, but I'm not looking for trouble either....

I've got to decide about the head - there's a broken spring, so do I replace that, have the head ground flat and move on, or go all the way with guides, springs, valves, etc? -
dunno - usually at this point I go all the way with things, clean-up and paint, etc, but it's difficult in freezing temperatures - I can't get the pressure washer out and it's going to be too cold even for the carwash for the foreseeable future -
dunno - what do you all think?

To check rod and crank bearing clearences just some Plasitgauge at a local auto parts store. It's cheap Maybe $3 for a strip of palstigauge. EXTREMELY simple to use. -PV8

PS. Last ime i tried to buy some Plastigauge at a local Napa there was only one kid in there that knew what i was talking about. The grey haired brush cuts didn't have a clue. The kid ran to back of store where it was on a shelf and brought it out to me.

So if ask for Plastigauge at a autoparts store u mite have to explain to them what it's for or try to find maybe ONE person working in the sstore that has a clue.
