Now with the pump disassembled you can see it's a pile of crap. The valve and bore have a good amount of scuffing, some severe. this causing the valve to stick. The face of the gears and pump cover as pictured yesterday do not have excessive wear, however, the thrust side against the aluminum pump body is another story, there is significant wear and scuffing on both the gears and especially the pump housing. The rotors have a good amount of wear as well. The wear in the pump is obvious but would not cause a loss of pressure, yet, but the stuck valve is definately the culprit. I do change my oil and filter regularily so I am thinking this is typical as mileage increases.
