Rebuilding the L134. I am not going to go too in depth into rebuilding the L134 since there are great instructions in the mechanics manual. I will take photos along the way and give some pointers along the way. The Willys L134 (nicknamed Go Devil) is a straight-4 automobile engine that was made famous in the Willys MB and Ford GPW Jeep produced during World War II.It powered nearly all the Jeep vehicles built for the U.S. It was later used in a variety of civilian Jeep vehicles.
