Foreign debris & excessive crush, or oil starvation? Same story on all 8 cyl's, but the journals look fine. Bought from a guy w motor knock who bought at auction, and the title reveals it switched hands quite a few times in a short period, leading me to believe someone may have tried to replace the bearings, wasn't clean, and over torqued the caps, but all bearings have 98 on them, this is a 99' jeep, oil pan gasket was very stuck, none of the bolt heads were stripped, and rod cap bolts seemed to be consistently torqued. Going through the rest of the vehicle, doesn't seen like much was done in terms of maintenance. Oil pickup wasn't clogged or anything. Run low on oil, clogged passageway, incorrect installation, out of round crank? Thoughts?
