Re-ringing after 70 miles?

[deflator]

I had a rocker arm crack in two, and all the valves smashed the pistons badly. I fixed the gouges up best I could on the pistons, then tested for pinched rings using this method: http://www.dsmtuners.com/forums/newbie-forum/450572-how-check-pinched-bad-rings.html

The oil drop was minimal after a few days. After a week, one had dropped noticeably, but only by a few centimeters. But when I just unwrapped it after a month, one cylinder has 3/4 the oil left, one is dry, and two are half empty.

This is alarming to me, since it seemed okay at first, but since it is a new motor with 70 miles on the rebuild it is probably a bad thing that they did not drain evenly.

Since it is almost new, can I get away with a minimal glaze breaking and a new ring? I broke it in hard.

^^ are you saying all this happen before or after the rebuild?
You need alot more than 70 miles on a break in man. Your supposed to put the engine thru 3 heat cycles and be more around 800 miles for a proper broken in motor. It's possible the rings havnt even set all the way with only 70 miles, go drive the dang thing get some miles on it. And make sure to change the oil properly and use the correct weight.

That's why I don't know how to judge the results of the oil-leak test, since I don't know how broken in it is yet. It happened with only 70 miles on the rebuilt motor. I was hard on it from the first mile though, using the motoman method of break-in.

A week for the oil to drop? a month and 2 are dry....

I would say bolt the head on and check things out. Drive it, leak down test, look for blueish smoke. Watch for blow by.
