Oil pressure problem, Help Please.

Put the Cranes back in,had these. A damn nice lifter... I love Howard's cams,Crane's drop in lifters,flat out the best.
it's got the crane lifters and crower cam in now, with the pressure down. it had good pressure before with the howards cam and howard lifters. but the lifters kept elongating the cup in the top of them thus the crane lifters, and the cam was changed because it has wear in it from the lifter wheels so i had to replace it.
