Sure glad to have some more Willys fanatics that have work to do!!! Regarding oil leaks, I heard of a trick...when the engine is out and on the engine stand, create a vacuum by sucking the air out of the block at the dip stick, then go around all gaskets and seams with silicone engine gasket...perhaps it would work if you can create the suction....(no jokes here) I do have an extra 4 cylinder from a '51 available, sounded like a sewing machine when I took it out. It has been sitting in a crate for 10 years however...I bet $300 would buy it...plus extra parts. I like pictures so take them often and post!....Enjoy! :cheers:
