Symptom: Diesel in Crankcase

I have never touched a diesel engine before, but I am reasonably competent behind the right tools. I am hoping someone can help me in figuring out if am approaching my problem correctly.

I just bought a 2003 5.9 HO 6sp that has (Developed?) an issue. When purchased the oil was at the correct level and reasonably clean not fresh. Upon changing the oil yesterday, I came to need more then 3 gallons of containers for my used oil (By about 3 Quarts!). Smelling like diesel I double checked the level letting it run for only 45 seconds and parked it. I browsed you tube and a few post, I ordered a injector leak kit (the cheapest start) From what I can understand, this will only show if fuel is leaking into the top of the head and of course mixing with oil at this point. I would also more then likely purchase some dye and put it into the fuel filter to help identify any other topside leak. I have read about two other possibilities.
2) stuck injector
3) Injection pump leaking at the front of the pump into what must be the front case cover??..

Without guidance I guess I would pull the injection pump inspect it and verify a bad seal or not and regardless replace any seals and reinstall. Open stuck or leaking injectors resulting in fuel dumping into the cylinder has me stumped as how to verify.

I should clarify. I only ran the motor for 45 seconds after the oil and filter change.In addition I did not thinking about it. I am assuming one can not due a leak down test on an individual injector due to the common rail setup.

So I have pulled the valve cover off first just to look for the obvious. Nothing came screaming out at me. I then noted that when the ignition is on in the run position there is a ticking noise coming from the valve-train. After grabbing my high-tech listen device, (2" PVC) it is the #1 cylinder injector. Since I can not here what injectors sound like when they are firing, I will have to assume that is what it is doing? Can I verify that this is an injector issue and rule out that something it telling it to fire with a digital meter?

Appreciating any guidance
