The problem with the Corvair is that there isnt a way to get a pressure after the oil enters the galley for the bearings. The original setup is to get pressure just after the pump. I would read pressure after the pump, filter, and cooler so I get pressure just as it enters the main galleys. The filter and cooler would be a full-flow system with an internal bypass at the filter only - non at the cooler. It seems to be the simplist way to route the oil system on the Corvair. Maybe not the optimal thing but best I can figure with this design..If someone has figured out another way please let me know...

Bill, OOOpsss, forgot to address one thing. Oil pressure should be read at the lowest point in the block, not the highest point. If you read the highest pressure, than when you get a drop in pressure, damage may have been done elsewhere. If you see the pressure at the lowest pressure in the engine, it will drop first there, and might give you adequate time for shutdown prior to damage. Hence, on a small block Chevy, read the pressure at the last cam bearing, at the top of the block, then at the filter near the oil pump. Pressure loss there ensures that the rest of the block is still getting good oil pressure, and prompt shutdown may only require correction, instead of partial/total rebuild. Thoughts....
