I have an A engine that I use for touring that I built a couple of years ago. I inserted the bearings and a few other things including pressure feeding the middle main bearing. I made and fitted a pressure relief valve to maintain 25 psi to it. The engine has proved to be EXCELLENT and very reliable. I am now starting to project to build another like it but I find that the Stipe oil pumps like I used in the first engine are not available. I know the instructions with the inserts say that the original oiling system is adequate but I cruise at about 50 mph with a camper trailer behind. The engine is working hard and I MUST have reliability so I want to pressure that main bearing.
Does anybody know where I can get one of those pumps and as an alternative, what other pump can be grafted in. Will a brand new A pump do the job? What modifications would be required to it? I wonder whether it can be made to work by restricting the flow into the top of the motor to up the pressure but I wouldn't want to restrict it too much - how much is good?
I've heard that an oil pump from a V8 engine can be made to work but they are as scarce as rocking horse crap here. What modifications are needed? Does somebody do it and able to sell a completed unit? What are the chances of buying a V8 oil pump?
Any other suggestions??
