It is my understanding that the internal pressure relief valve is there to
provide oil flow in the event of an extremely dirty filter. When this valve
opens, oil bypasses the filter, and flows directly to the engine. It is
better to have dirty oil flow than no flow at all. For us LBCers, who
maintain our cars well, this should never happen, therefore, a pressure
relief valve is not required! Am I wrong?
