    Default Need help diagnosing injectors

    I am getting fuel in my crankcase. I am looking for a duramax expert in my area with a TechII or efi live to diagnose my problem before I buy injectors. I also need work done on Allison. I live in North Central Ohio between Toledo and Sandusky. Any help would be appreciated.

    A scan tool will not diagnose your injectors other than give balance rates which is a very vague and generalized reading. If you have fuel in the crankcase it is almost undoubtedly injector related. In rare cases the CP3 can do it, but almost always injectors.

    We are stocking the LB7 injectors with an improved nozzle design that promises to rid us of the blue/white smoke issues that have become so common.
