I own a 1984 Jeep Cherokee. I replaced the 2.5L engine with a low mileage 2.5L engine 3 years ago and now I am having problems starting it (carb is 2-years on rebuilt) and it is idling ruff (probably from low compression).

The body is immaculate (pan restoration) and new paint.

Do I keep replacing the four-banger? Or do I try to do a swap for a 2.8-3.4 or 4L? I realize that the swap is involved as it requires harness and fuel pump, and probably other stuff. I just don't think the 2.5L was designed strong enough for the Cherokee.

Any suggestions would be appreciated.

Cheers,

 

I found an 86 Wagoneer with 3.4L V6 that my friend and I are going to inject into my Jeep.

I a definitely looking forward to this upgrade.

unless you have some big emotional investment in the truck i'd just buy a later modael with a 4.0 already in it .. that's just me, im lazy

 

Yup, I restored my Jeep from the underfloor up, new underlay, got rid of carpet and replaced with rubber/vinyl all metal finish, new paint.

Now I put a 3.4L with 5-speed, replaced dash, all wiring from door up (including ft-light harness), replaced both ft and rear diffs hub-to-hub (are you sick yet) ...

Just waiting on a zero-balanced flywheel today as a matter of fact,

Here's my story for your enjoyment,

You guys are lucky to have this thread as I promised the gentleman who sent me the new flywheel. He'll get the finished version.

Cheers,

 

that's a real good reason to keep it .. there's a guy on comancheclub.com who did the 3.4l swap from a camaro i believe .. some good info on there
