I'm working on rebuilding my B18B1 bottom end. Stock crankshaft, new stock main bearings and thrust washers. Here's my problem: I installed the new bearings/washers per service manual specs. I used engine assembly lube in the proper places, I thought I had too much at first so I went back and re-lubed several times, then re-torqued. The problem is, when the main bolts are torqued to 56 ft/lbs (specified in the manual) the crankshaft will not spin. I torqued it down to 50 ft/lbs and it will spin but only for 3 revolutions or so before the crankshaft seizes and it becomes very difficult to get it to spin again.
I know 6 ft lbs doesn't seem like much, but I've seen what a poorly assembled engine looks like. Keep in mind I have checked the new bearings with a micrometer to see if they were the same thickness/width etc. and everything seems to be perfect. I'm just not sure what is going on.
Any help would be appreciated.
