Would anyone know by my engine number if it should have a 3 or 4 dip oil pan ? thanks # 10750518
from the encyclopedia
On July 18 the crankcase was changed to the "four-dip" type.
your engine number is OCT 24 so 4 dip it is
I forgot July 18 1924
David, your engine was made November 4, 1924 at the Highland Park plant. (Some of the production came from the new River Rouge plant)
