There is not but one thing it can be IF you have that much pressure and that is is the pump! 4.3-5.0-5.7 engines. Did you use a test gauge screwed into the sending unit port? Sounds more like blow by if oil is coming out of the dip stick tube, no oil pressure there. The engine cant be breathing, no fresh air, breather, and no pcv action. How much oil is in the engine??? I hope you find the problem.
