With my RV down for major mods for almost a full year, I began looking for ways to protect the engine. I discovered these auxilliary oil cooler boost pumps for auto racers at summit racing:

I used inexpensive hardware store fittings and hoses to create a loop drawing oil from the second oil drain and force feeding it anywhere on the oil cooler loop, it does not matter what position the vernatherm is in. The gauge on the bottom reads output pressure from the aux pump, and the one on top is connected to the usual oil pressure tap. As you can see, it maintains about 40 PSI for as long as ypu want it to flow. Spinning the engine with plugs removed kicks the pressure up about 10PSI at the oil cooler circuit and abput 8 PSI through the oil channels. You can recirculate oil as long and as often ad you like as frequently as you care to. If I was storing overwinter in a cold climate I’d set this up each year. I”ll let the photos tell the story.- Otis:
