Is anyone having trouble with a 602 crate sealed engine?

[adamgoff1981]

Oil pressure drops off drastically when at operating temperature, and also have a oil leak in rear seal installed a new seal ran one night and leaked again. Any help is appreciated

If it's a GM crate motor, take it back. They stand behind 'em . . .
