TBH honest mate, abit of white metal was stuck on the journals. I removed it but abit of careful polishing and the journals were fine no scoring at all. The engine was run for long at all. It was oil pump failure. New shells, new oil pump. 100 psi when cold going to 70 psi when hot. just have to run it in abit and hope the oil pressure doesn't drop too much or else i suspect the mains are damaged.
