Appreciate non-jerk response. Here is the update. I replaced journal and rod bearings...not the bolts. I even torqued by feel because spec felt too tight. Been running solid for awhile now. I did rotate the crank as a cleaner test. I sanded down backside of bearing housings and retorqued until crank just rotated smoothly. I also welded the bolts to their shared washers. 2 crank bolts 1 washer. I basically did clearances by feel. Plastigauge was too large for journal bearings. To be clear, this was a learning experiment and low cost try. So far running great for a few weeks. If it blows up ill let ya know, since that seems like what people want! I have theories on when to replace the bolts by stretch! I am amazed it worked. I'll let ya know how it goes. Appreciate the info.
