oil pressure disappeared.
I previously had 2 cork gaskets and a metal windage tray. Now I have a windage tray rubber gasket combo. Probably a 1/8-3/16" shorter. Since I use studs and the gasket is rubber and no RTV is used, I am tightening the pan up and it could press up against the pickup and either plug it or crack it. No way to feel that happening. I should have remeasured the drop of the pickup but I did not. The pan and pickup were used for many miles. The pickup is a 440 source pickup designed for stroker motors. It is narrow at the threaded end so that is does not hit the crank..
Many pickups are welded by the threads and the flange hits the crank. I cannot see the bottom end of this pickup to see if there are stops, say 1/16-1/8 inch to prevent it from sealing against the bottom of the pan. If I measured before to get it close, I could have had it 1/16" away.
