L-head from a 3A Mukwonago, WI **SOLD**


UPDATE: **SOLD** Was $250.


” Willys L-head four cylinder engine was removed from a Willys Jeep CJ3A. This will also fit in the CJ2A, M38, WWII MB and GPW, and some early Willys Wagons and Trucks. This one has been in dry storage for about a decade. It used to turn over years ago while it was in the shed, but I can’t seem to get it to turn over at the moment, and I don’t want to force it. R

emoving the head, I see what looks to be normal wear to the cylinder bores with a slight ridge on the top, and the pistons are currently at 0.040 over, meaning that it can still be machined out to 0.060 when rebuilt. It has a Jasper Factory remanufactured engine tag on the side of it, so it had received a rebuild at some time in the past. No signs of cracks or damage on the block, but I do see that the exhaust manifold does have a large crack. The intake looks to be in good condition. Will include everything shown, plus I may also have a working starter and an untested generator to include with it as well. Please let me know if you have any questions.”

1947 CJ-2A Spring, TX **SOLD**


UPDATE: **SOLD** Was $500.

Engine spins.

“1947 Jeep Willys CJ2A Go Devil L-Head 4 cylinder engine. I don’t have any of the details on the motor because we just purchased it and we are going a different route with the drive train. Everything seems to be in place. It is not locked up and does turn over. We were told it ran a few years ago when we bought it but we never planned to keep it. Also, the tub is available if anyone needs parts to repair another tub. It has the normal rust spots and I didn’t want to deal with fixing them.”

Willys L-134 Superior, MT **Status Unknown**


UPDATE: **Status Unknown** Was $800.

I wonder if this was an industrial engine.


“Flathead 4 cylinder Willy’s Jeep Engine, WW2 vintage. This engine starts on its own with just being choked (no other starting aids needed). Oil pressure is good, and there are no knocks, or crankshaft “Chuggle”.
The compression of this engine is 75-90 psi, and it can still carry a load (it was the powerplant for a functioning welder). There are traces of olive drab paints on parts of the engine, and the timing cover has the rivet in it that wartime Willy’s had. The serial number of the engine is MB546645. The additional numbers on the engine block are 1-11, 638632W2 A, and NI-CR N2 ( designators for a nickel-chromium iron block alloy; for those of you who don’t know, this hardened block material is one of the reasons that these engine run forever).
I believe that this engine could be dropped in and ran as-is for quite some time, or it would be an easy one to freshen-up with piston rings and a valve job. I prefer cash as method of payment. The engine is currently palletized, and is available for local pick up, or shipping arranged by the purchaser. These engines are not getting any easier to find, so even if you have a good engine in your Jeep, it might not be a bad idea to have a spare.”

Allstate L-161 Orenco Station, OR **SOLD**


UPDATE: **SOLD** Was $100.

Good price. It would make a great “Allstate” Jeep project.

“Pulled this Allstate L161 out of a CJ2A Willy’s Jeep. Definitely not original to the CJ2A. My best guess is this from a Willy’s Jeep Station Wagon or Henry J from the early 1950s.
The casting on the top: ALLSTATE, 6L161
Block Casting: 741878-2
It has run in the past; just been a project car for years and decided to go with a newer engine.”

1945? CJ-2A Engine Clarkesville, GA **Status Unknown**


UPDATE: **Status Unknown** Was $1795.

Given the serial number, it seems more likely to me this is an early ’46 based on this chart.
