Tweet

look like trash to me dirt from many things but was the block clean all oil galleys. brush then wash good blown out . crank cleaned well ? brush run thru all oil holes . i deburr all oiling holes and inside has they can have metal hanging off oiling holes when drilled then polish the crank . did you check housing bores on rods for size . this will tell if the rod was round and to size as well if a cap was mix up . did you check for oil clearance on rod bearings . did you mic the crank for size . that bearing in photo looks like it is not past the babit ,but crank may need to be polished. can you catch your nail on the crank journals? if so it will at lest need a polish. you said you dry crank it. was any assembly lube on any thing ? dry cranking is a big NO.. NO with no lube. take off the oil pump cover and look at the pump well. gears. and cover will tell how much junk went thru the oil pump if the pickup and pan where clean off the get go did you find your knock ?
