I think this is your best bet. If it has good compression evenly, I'd use it as is.
If you get weak compression, then apply oil through the spark plug hole and retest, if you get better compression, then you have worn rings, or something like that.
Ahhh!. I am torn between new rings that may help my machine and old rings that may save me some money.
So, is there any major issue with re-ring? Any standard procedures? I guess mark it all w/ punch, clean the pistons, hone the cylinders, pull the oil plugs, pressure wash the block.
I did it on a toyota 42r something once and it was blowin oil out of the valve cover hole in 3 weeks. I did it on a 305 chevry once and it ran great till I wrapped it to 7 k every day for a month, then the crank broke in twain for some reason.
