well interesting post as i was the one to purchase this repaired block not knowing it had a hot oil pressure problem,but all is good as it was used and what i was looking for,so after reading i went out and spent some time on the block,,plugged all mains oil passages ,blocked off head feeds,capped off all external places put in a used cam and pressure tested system,as dragula told me has good cam bearings well little soap and water shows i have a problem with rear cam bearing ,removed rear plug and put cam in back side has double the clearance as front bearing, is this the possible issue i would hope as i will rebearing cam and put together a 572 this winter after doing for checking into the block. i hope all works out and am happy to have a long awaited hemi block
