Black oil quick

[G.M.]

33 years ago I installed a brand new WWII engine in my 39 convertible. I used
Castrol 20/50 from day 1. The engine ran the typical hot, up near 200 and the
oil got black in a few hours. It also used a quart between changes. About 9 years
latter I installed Skips pumps and cooled the engine down to 180 with
Bob Shewman's 180 degree stats that allow a non restricted full flow of coolant
through the engine. The engine ran at 178 to 182 on days in the high 90's. It
stopped using any notable amount of oil between changes and the oil don't get
black but is a dark yellow. At 85,000 when changing the oil I stuck my finger up
in the drain hole and the pick up screen moved, I did it again and the pump
moved so I pulled the pan and the pump was loose where it was welded to the
flange. I brazed it and put it back together. Also the Castrol kept the engine
looking almost new and had no sludge at all in the pan. It now has over 130,000
miles, runs perfect, is quiet and burns no oil. Attached is a picture of when I had
the pan off. G.M.
