I need to know if pressurize the water jacket on a cummins

Customer Question

I need to know if pressurize the water jacket on a cummins isx head, can I check for injector tube leakage without the injectors installed
JA: We'll do all we can to help. Tell me a bit more about what's going on so the Heavy Equipment Mechanic can help you best.
Customer: I am pressure checking a head off the engine and with 25 pounds of air pressure the tubes barely bubble, but the injectors are not installed. Do I have to have the injectors installed and torqued to properly check to see if the tubes could leak into the cylinder?
JA: Is there anything else important you think the Heavy Equipment Mechanic should know?
Customer: Everything else on the head looks good. It had a gasket leak it why it was pulled off and no signs of leakage from the tubes on any kind in any cylinder.
