Whoever rebuilt that motor didn't know what he was doing. I would not put more money into it.
How about finding a deal on a low mileage stock motor?
I picked up a used complete 4.0L the other day out of a 93 Jeep Cherokee for $400 with all the engine accessories including MPFI . I need too do a little tear down and look it over, as it may just bee a core for a long block depending on what I find. I may just keep running the TBI injection I got or if I can source a complete engine wiring harness it might change over to MPFI.
