Finally got around to working on it. I removed the oil pump and removed the valve. I inspected the oil pump and put a couole of psi pressure to see if it was leaking at the seal, nothing. I reinstalled it with new line and no cutoff valve. I bled it and ran the pump using a drill to ensure it was pumping, worked as advertised. I installed a shutoff valve in the rotary valve line. should know today if it is leaking
