So this is my first post so I hope I don't break any rules. I just picked up a ford 4000 diesel 4 cylinder today. The seller told me what he knew as follows: He purchased the tractor about five years ago from his boss who in turn purchased it just after it had been rebuilt(the seller thinks the motor was rebuilt but not the transmission though he really didn't know for sure). the first four years the seller had the tractor it ran fine and was mainly used late summer to cut shooting lanes and bushhog around his deer camp. The majority of the year it sat in his (very nice I might add) shop. This last summer when he cranked it to load it up it was missing badly and smoking blue smoke like crazy. He said there was diesel in the oil so he had the injector pump rebuilt by a local certified Roosamaster repairman. Despite the rebuild it still smoked and missed(despite the smoking and missing he went ahead and bush hogged for several hours with some reduced power but it didn't get worse the longer he used it). The pump guy bench checked the injectors said they were good and also checked compression in all four cylinders(seller didn't remember the numbers but remembers the pump guy saying compression was fine). seller told me he's checked the pump timing twice and it looked right to him. So any suggestions on what to check first/what order to check things? Sorry for such a long post and such a general question.
