The jeep was used in a Teak plantion here in Belize Centrel America ,I bought it with a low end knock , found a crank in a sister engine and put it in along with new bearings , I never checked the codes as it was running smooth. I the sent to the USA for the chiltions manaual has not arrived yet . I use the CJ s and Wranglers to do Jeep Jungle adventure trips in the Cockscomb basin wildlife sanctuary, I found some 87 chorkees with factory installed Izzu diesels if I can transplant one of them it might solve the problem.
