How do I know if I have an L flat head engine 4 cyl or the later F head over head valve 4 CYL engine in my vintage jeep?
The quickest way to determine what engine you have will be to look at the following items. L flat head engine will have the plugs and plug wires pointing straight up on top of the head. F head over head valve engine will have a metal valve cover and the plugs and wires will be pointing out at an angle on the driver's side of the head. It is very important to know what engine you have before placing an order for parts. Your jeep might have had an engine replaced over the years that might not match your year's specifications.
