Those are easy engines to work on and run pretty smooth when tuned right. The rest of the postings are right, Carl Walck's in P.A. is the best place to order from. He'll need the serial # and other info to find what you're looking for. Some of these engines were over/under sized from the factory, depending on the castings and such. This can be found on top of the pistons and on the crank journals and such. I'd tear it down before ordering parts.

For a few years they used the same engine that�s in a Ford 2N,9N,8N tractor. If you post a pix it would tell the story. I have sold many a engine kit for�em and it�s the same as the ford tractor. Do a search for 9N, 2N, 8N engine of email me for a pix.

If it is actually a jeep motor it will have Willys or possibly even Ford on it somewhere on the head casting. The jeeps were 134 Cu in flatheads, with the carb and exhaust on the drivers side of the motor. For parts.. try Ron Fitzpatrick in Oregon.. (G503.com then check on the parts link.) Also Walck"s 4WD, Willys Acres in Canada, Willys Overland, and there are a few others. All have websites. If you google "WWII jeep parts"you will probably find most of them. Napa can provide some of the parts but at a premium price compared to the jeep specialty houses.

No, it will not have sleeves if nobody has installed them to correct a serious cylinder problem. If it is set up you probably can get away with boring oversize. They are a fairly simple engine. Portrayal Press reprints all the manuals from the original Army issue ones.

The engine blocks were cast by Campbell Wyatt & Cannon Foundry in Muskegon, MI and then machined and assembled by Continental Motors on the other side of town. I rode my bike to school right past the foundry at Sanford and Broadway and looked in the open doors which were right at the sidewalk edge. We could see into the foundry and it was hard to detect anything but dim incandescent lights and eyeballs in the casting operation mayhem. The whole area was filled with blue smoke from the oil in the casting sand and smelled pretty rotten. Since Muskegon has a lot of beach sand readily available it was a popular casting center. Casting sand uses sand, clay, oil and water to make it both permeable and ridgid enough to use for molds to pour cast iron. I also worked as a Thermofax copier repairman and was assigned to repair the machines in the Continental Motors plant and walked past the line where they were assembling the 4 cylinder engines and wonderd where they were using all these funny little 4 cylinder engines. I was told that most were Jeep engines but some were used in Ford tractors.

That sounds like the one I have a model PE-95-G I was lucky enough to find one in MINT cond. with only 75 hours on it. Now it has 175 hrs.

I don't think they have sleeves. I have seen Jeep Engine parts for sale on the web,but would think maybe NAPA might be able to get them. I was at a military show that had books on them but they were pretty pricey. The engine should be same as an old Jeep which old Motors or Chilton manuals cover.
