Snowman51 A 51 6400 with a 235 full pressure came to me with one of those noises that you can here the oil pressure shut it up. I installed -.002 rods and mains fixed it !! It now keeps the 30 pound gauge pegged summer and winter,have driven it 9000 miles so be happy like me. Also couldn't see much wear on the shaft,figured it would lock it up ,didn't ...turn by hand on the flywheel,start run ride and drive !!
