- 1985 CJ-7, T-18, twin stick Dana 300, AMC 20 series diff
I bought a 1985 CJ seven from a guy who acquired it from someone who passed away. That builder did a lot of custom work. The current owner really had no idea what he was dealing with, and I bought it knowing it had fuel injection, on board air, lockers, 411 gears, and a bunch of other nice mods, including Clifford, intake and headers. It’s now several years later, and I developed some engine problems. Decided to swap the motor with a rebuilt that I picked up. I bolted everything today on the old motor, maybe something I should’ve done sooner and the head is most definitely different than the standard AMC 258 i6 / 4.2l L head that’s on the motor I purchased. The motor I bought was just board 60 over with new pistons and bearings. The old motor is missing some metal around the rear, main seal and leaks oil like a sieve and developed a weird knock recently. This is not my daily driver so I have options, but I’m not sure what I’ve gotten into.
The blue valve cover is the engine I bought, the one with the valve cover off is the head that is currently in my CJ. I also included the header gaskets for each of these engines for comparison.
Advice would be appreciated.
