Perhaps too simple an answer for a more complex problem.
WHY was there such pressure in the cap? Doesn't the oil from filter drain back into Crankcase (which is NOT under pressure? Cap NOT Designed for that type of pressure, or else it was CUT across center. Part of Filter element that is visible looks New & intact. See previous Thread on this issue:

ANYONE know HOW oil Pressure is regulated in the filter? Where is any pressure valve located? Got a reference to "FUB" of oil supply?
