I’m assembling an early 1916 Chevrolet 490 engine and cannot find any good pictures of the oil pump feed to the sump. Unfortunately it was all missing. The picture is of my engine upside down with an oil pickup in the sump and another input feed for the big end gallery. The oil pump is a 2 piston design but only has one inlet/outlet. The other is plugged?
Any photos or diagrams would be great. Many thanks, Richard Skinner.
