The Stovebolt Site Forums The Shop Area The HiPo Shop Opinions on the Jeep 4.0 engine

I had an 86 CJ-7 with the 4.0 and a four speed. The engine was pretty good, but the carb that came sith it was terrible! I think this was the beginnings of pollution control, and the engine had about 100 vacuum hoses and valves, and the carb had a weird stepper motor controlled jet that changed the jet size depending on what all of the vacuum hoses sensed. I rebuilt the engine and threw out that carb ASAP. But it did have great low end power. And lousy gas mileage. And it was a [censored] keeping oil from leaking out of the valve cover.

But it was a great vehicle for where I live, would go through anything, manual tranny and manual lock out hubs.

I also had an IH Traveler (sort of between a travel all and a scout, with a removable fibreglass hard top (if you had four people to remove it). Big V8, auto tran, auto lockouts. A monster to drive and park, but it would go anywhere. Got about 8 miles to the gallon!
And getting parts for it was horrible. It seems that IH would make a change, but continue using the old parts until they ran out. You couldn't order by year, you had to get the number off of the part.
