DAY 3:
pulled the tranny and transfer case. tranny needs a rebuild as the clutches burned up and it wont shift into 3rd. will probably sell as a core. transfer case I sold
I started disassembling the seized engine to figure out what caused it to go bad. took the intake and heads off and found nothing wrong there. took the pan off and it became very clean a bearing was the cause as there was metal flakes everywhere. unbolting all the main caps showed extreme wear with deep grooves, to ill present, and bearings in horrible shape. Taking the rod caps off showed the same but the #2 and #6 rod bearings (which are together on the crank) were obviously the cause. the bearings were actually missing and the caps were banged up bad enough that I had to cut them off to disconnect them.
this was a remanufactured crankshaft and came with matching 10/10 bearings, I used a lot of assembly lube, primed the oil pump, and checked clearances. don\\'t know why the bearing originally had a problem. im assuming that the bearing must have spun, seized on the crank but the engine didn\\'t seize the engine. it spun until it flaked apart and the cleacence became soo much that all the oil pressure was going to it instead of the others. the others without oil pressure would then eventually lock up till it seized the engine.
good news is that the engine is still useable. I have the original crank which is in pristine condition (no grooves at all). everything is good to reuse but it will need 2 new connecting rods, new bearings, oil pump, pickup screen, gaskets. also I plan on using it instead of the 302 from my old truck so I have more power.
