lost all oil pressure but not flow

DING DING DING we have a winner! pulled the valve covers and yep theres a hell of an s curve on the intake pushrod of #4 ill pull the rockers and check my other pushrods to see if they are bent as well if not i may just call it bad luck as the cup of the pushrod is loose from the pushrod itself and it looks like theres a ridge inside which probably took up what clearence there was and something had to give...

anyone else have any suggestions while i have the intake off and am checking pushrods?
what kind of rockers are you running? If stock, stamped-rockers, I'd check rocker geometry and lifter preload. If adjustable rockers, I'd check shaft oiling/clocking, first. Then, I'd check rocker geometry and lifter preload, second.
