    New to site, i have a 3116 that i am working on for a friend and am having some problems getting the white smoke to clear up , the engine originally was in a topkick truck and was taken out and put into a D5m dozzer , i have replaced injectors and run the rack and it spools up fairly quickly but smokes like a train at idle it is burning clean any suggestions would be greatly appreciatied

    Brian sounds like timing? I know you must have the tune up kit for these engines? They are fussy to set up.

    Here’s a couple of other problems that effect power.

    I’ve experienced compression getting by the injectors (pressurizes fuel tank) which required the seats to be machined or replaced.

    There is also a diaphragm in the governor that fails effecting the fuel rack. http://schoolbusmechanic.blogspot.com/2009/07/cat-3116-troubleshooting-no-power.html
