Notice with the tray in place that the farthest stud back on the driver-side is exposed (arrow). The hole is an extra-large hole so oil can drain straight down to the pump. When all the nuts are in place, they are torqued to 35 ft-lb. The upper nut will work as a jamb nut to keep the tray securely fastened. When everything is torqued and tightened, it should all look like this. This motor will now have zero problems keeping constant oil pressure, no matter how hard it goes around a corner.
