In my 1G I had my block honed, measured bore, and hot tanked. Then I had my crank polished, cleaned, and mic'ed. The machinist said they were both within spec, no boring or turning was necessary for just a stock rebuild.
I ordered standard size bearings and measured everything with plastigauge. Below are the pictures of the plastigauge for the rods. I assembled everything with assembly lube and primed the engine until oil was coming out of the ports in the head.
The car started up great. Vitals looked fantastic via pocketlogger. Breaking the motor in motoman style at mile 11 I spun a rod bearing in cylinder #2 and the motor completely seized and rolled to a stop.
Second round, I've gotten a different crank and am about to repeat the process with my own bore gauge, micrometer, and 6 pieces of plastigauge around each bearing. Does anyone have any ideas what might have happened or what I might have done wrong? I'd rather not repeat the failure. On a side note, I put new bearings in my galant 1500 miles ago and haven't had this issue.
Thanks.
