Rusty, you can create a 5 psi bypass of the pump. In suction the pressure
relieve valve

will be shut. If the pump stops, the engine will pressurize the pump intake
side and the spring loaded valve will open and let the engine push the oil
through at only 5 psi. How about that? Buly
Hi Buly,
If I understand you correctly, when the pump stops, you'd have 5 psi on the
turbo seals? If they would take that, I don't think I'd need the pump at
all :-) Maybe I didn't understand you correctly?
Rusty, you better check with a turbo specialist. The valve could be a just a regular check valve that will open at 1/2 psi.
Buly
