1956 Willys CJ3B Rebuild and Restoration
Mike House posted a topic in Vintage Jeep® Vehicles 1941-71
It has taken me nearly 35 years from the moment I fell in love with the willys jeep to finally buy a project Willys and build one for myself! Recently while browsing craigslist I found an add for a 1950s cj3b for $1,500. The pics made it look like a minor rebuild project but of course the guy I got it from did not know much of the history of the jeep. He told me it was half 3b and half M38..... I bought the jeep and trailered it home. After several weeks of soaking the cylinders I was still unable to get the F head 4 cylinder freed up. For the next few weeks I did research on an engine upgrade and settled on a late 90's GM v6 with TBI. While trying to find the right deal on an engine I stumbled across a guy selling jeep parts and turned out he had a Dauntless V6 still sitting in a 1967 CJ5. I bought the engine, flywheel and bellhousing for $400. This engine was also seized up as it had been sitting in a field for several years. I got the engine home and tore it down to the block. The cylinder walls were scored and worn but the block, crank and heads seemed salvable so the block, crank and head went to the machine shop. The body is in very rough shape. If I had the tools and shop space I would probably rebuild/repair the body. Still undecided on the path forward with the body. Other than I pulled it off and striped the frame down. Pulled the T90 and Dana 18 apart and found the transfer case to be in good shape but the transmission was a basket case. I have since rebuilt the transmission and bolted it back up to the transfer case awaiting the motor from the machine shop. I plan to couple the Dauntless V6 to the T90. This will not be a hwy vehicle or a performance vehicle so for now I will stick with this drive train. I found the frame broken just behind left front spring shackle so I repaired the break and fish plated the outside of the frame. And that is where I am at to this point. -
Have just disassembled ’69 225 which has 42,000 original which I believe to be accurate due to condition of rest of CJ5. This sat, obviously for years at a time. Lot of sludge, blocked oil passages in head etc. Engine components all look very good. The only thing I really question is the cylinder walls have wear marks which remain after cursory honing. Pistons appear good as do the rings. I’m leaning into boring and going over sized. My question is are 2nd pistons and rings available and where. Thanks

Hello fellow jeepers, I'm new to the forum and wanted to share my current project. I have an old flat fender that's been in the family for around 30 years that was in dire need of restoration. It's turned into a ground up, the frame was twisted and severed in the middle and the tub was all rusted out. I completely rebuilt the frame, straightened it all out and reinforced the weak areas. I didn't box the frame as I want to retain some flex. I did some extensive panel replacing and patching on the tub and built new floor pans for the front and rear. The axles are stock D44 rear and a custom built super 44 up front. I still have the Dana 18 tore apart, but ready for assembly. I had to find a shop that could replace and fit a new bushing for the output shaft. Other than that it's getting a full rebuild kit. The Jeep has a T19 from an IH, it is still in great shape and will only get a small parts kit. The engine that was in it was a tired 225 with a cracked block. I got a couple other oddfires when I bought the Jeep and decided to rebuild another 225. After going through the cleaning machine, my machinist found some deep pitting in some of the cylinders. The block was already .030 and with advice from TA Performance we took it to .070 and they ordered me some .020 Buick 350 pistons from Egge. Apparently they have seen a 225 bored .090 over without structural or cooling issues. Once I had those my shop sent everything in for a full balance. They refreshed the heads with new springs, exhaust valves+hardened seats, valve job,and new seals. I did some minor porting and cleaned up the runners to smooth the air flow. It's not a race engine but even the small improvements go a long ways. I still need to port match the heads in addition to the offy intake and the headers. I had Delta cam in Tacoma build a strong low-end torque cam. I was searching for some info last night, do you know what the combustion chamber size is on the 225 heads? Egge couldn't tell me what to expect for static c.r. That's probably enough for now. I'll post pictures in the days to come. -
Anyone know if it is critical what direction the oil hole in the lifter faces on my 225 odd fire. I popped them out to look at the cam, I kept them in order, but did not pay attention to this. Any thoughts? Thank you, Bryan
