Re: Cat 3116 engine fuel injectors ??
The 3116 can be turned up, it has to be done under the valve cover with some expensive tools and dials.
Injectors for a 3116 are less the $100 a piece. Labor to put them in is a different story. Kind of a complicated process to get it timed just right as each injector has to be set individually.
Better have someone work on them that really knows this engine!
