I recently bought a 1992 Peterbilt with a Cat 3406C 3ZJ full mecchanical engine. Engine is locked up, pulled pan and several piece of metal in the pan and at least 2 of the main appear black from overheating. Looking for suggestions on what to do next. Truck is not main source of income more of a project. I am guessing that sending the block and crank to a machine shop would be crazy expensive. I have a lead on a 5EK that is using antifreeze so that would need to be addressed and I have been told that I would need all the wiring harness and computer from a donor truck to make it work which is not availale. Looking for some advise on what you guys would do. Thanks in advance for all of your expertise.
That all depends on the condition of the rest of the truck. A decent used take out is 9 to 10K a rebuilt complete 28k plus depending on brand of parts used. And most likely any out there as rebuilders need a bunch of machine work, 32 years have passed since that engine was produced. Best to find a rebuildable core, expect minimum of 22K even doing the work yourself.
thank you for the options, I have a 12.7 Detroit in a 97 Pete, I was told that motor was using antifreeze. I was hoping to stick with Cat but maybe I should look into fixing the Detroit and using that.
Liner low in deck, liner protrusion with Series 60 is critical for the fact those didn't have much protrusion when new or issue with head.
