I work on cat engines. 3116 engines are known as 1.1 engines, meaning they are 1.1 liters per cylinder. Do you know how to set the rack on this engine, along with the injector height? You will need to have the tools to do this procedure. The tools used to do this are not cheap. Cat's are not a cheap to repair. Just a piece of advice. If your going to stick a diesel in your pickup, why not a 6.9 or 7.3 idi?? Or a 4bt or 6bt cummins? I deal with caterpillar engines on a daily basis, that is all I work on, and they expensive to repair. 3116 engines don't have a great track record in trucks, they did ok in heavy equipment. Injector cups like to leak, same with they oil cooler, water pump...
