Re: Rear main oil drain pipe size
I am not sure of Lincolns, the early oil return pipes do not extend into the pan very much. There is a possibility of then touching the oil pump. The early V8, 21 stud engine oil return is about 4" long, the 38-42 is only about 2" long see below. They both vary in diameter. Suggest you look in a chassis parts book and come up with the part number. The basic Ford part number is 6326. Below is a photo of the short 38-42 Ford V8 return pipe. Care has to be used installing these pipes, in the rear main, since they can possibly block oil flow, in the rear main cap. The 4 Cyl returns were spot welded in place.
