31 Deluxe Roadster too much oil, should I drain some?

using non detergent oil would allow sludge to settle into the oil plug cavity. When you say 1/2 inch you mean the drain plug was full of sludge. I don't see how you could remove the plug with a 1/2 inch of sludge resting on top? I wouldn't pull the pan just replace the oil with detergent oil and change it 200-500 miles and monitor the sludge.

This is the advice I got in 1956 when I got my first Model A. It worked then and will work now.

Ya, the sludge just kind of piled up on the top of the plug.
