    On a full case 1/2VW, the oil cooler is removed and in my case, the interface plate over the ports on the case is 1/2" alum that has a channel routed between the two case ports. In this configuration, the relief valve is almost non functioning since the oil gets to the main gallery in either case. So my question is why leave the diverter oil relief valve (prop end) in the case?
    With the prop end relief orifice to the oil sump plugged, and the spring and piston removed, the flywheel end relief valve still functions regulating pressure, and the full flow of the pump goes to the main oil gallery.
    All comments welcome
