Hello fellow zilvians. I've got quite a interesting issue with an sr I've rebuilt and would like you guys to chime in and see what you guys would do.
A lil history on the motor- s13 sr20det red top, ran and drove fine. It's actually my brothers motor. He pulled it thinking there was a issue, tore it down and found nothing major besides a lil bit of detonation markings on the head, block and Pistons were fine. Got a new head and added bc springs retainers and jun cams in it and we decided to throw new berings in it while it was apart. Had the machine shop check everything and all came back good...according to them
Now fast forward a few months, I've got the motor pretty much fully assembled using new bering(oem Nissan) plastigauged em and they came out pretty good. Sorry I can't Rember the specs. It's been at least a few months. Used Lucas Molly lube and put it all back together using the torque angle method per fsm. Now what happens is after the motor has sat for a few months the rotating assembly will not spin easily on the first rotation. Almost seems as if it's siezed. But once you break it loose so to say it will spin easily with a breaker bar. That concerns me but I'm thinking it could possibly be the lube drying up and causing it to be hard to spin. But not shure. I've never had a issue like this with any other motor I've assembled. Any input or ideas? It would be greatly appreciated!
