Lifter galley paint

One more anecdote. Back in the '70's when gas station attendants frequently pulled dip sticks to check crankcase oil levels, I had one attendant call me over to say no oil on the dipstick. I pointed out to him the oil level was right on the full mark. He was obviously accustomed to seeing oil as a dirty black color, whereas in my internally painted bracket motor, it was easy to keep it clear with frequent oil changes. One just had to be careful when checking the dipstick.
