Sounds like cavitation is possible with Granny's setup.

It sounds like it. I would be working on a much improved oiling system or an adaptor plate to run the later pump (50mm).

Feeding two sets of bearings from one pump is a challenge by itself. The later pump, or an aftermarket pump outside the engine would be my choice.

You can soup up the original pump quite a bit, but I don't know if it can do as much as this is going to take. If it cannot hold 75 PSI hot at the rear main, I would upgrade the pump.

Picture is pressure section of the Peterson pump. Suction in is on the end plate.

Pressure out is on top.

My first attempt at scavenging the rotary worked real well. For the front I used the front pressure relief gallery. I just cut a notch in the bottom facing aft. I pulled the oil out of the stock fitting on the drivers side of the cover, where pressurized oil used to come out. I plugged the gallery to the oil pressure "O" ring pad.

For the rear, I used a stock pressure relief valve, modified by gutting it. I cut open a section of the side of the body about 1 1/2" long. The open side Goes down and is indexed and held in place by the jamb nut. I pulled the oil out through the stock banjo fitting where oil used to go into the rear iron. The oil gallery up to the filter adapter was blocked off with a paper gasket under the home made aluminum block that gets oil into the rear main bearing gallery.

Then the pan can be dead flat, and the engine still looks kind of stock.

There were no bug screens, and I had no problems because of that, but you could put in some "In Line" filters from Moroso or Peterson.

This bottom view shows the extra oil line to the front main bearing and the suction lines to the front cover.

Hi Lynn,

That is very ingenious. I have to take my hat off to you on that one. Next time I'm allowed into the garage I'll have a look at my engine bits and get a better understanding of how to do that. It may be a good upgrade for me, as those pots are the lowest point of the car after the Prop hoop and with only 4" ground clearance there is a risk I could bash them. That's I ever get the car running again.
