    So I have a 1995 dodge 2500 4x4 12 valve cummins I changed the oil 300 miles ago along with head gasket front main and timing cover seal and valve cover gaskets. But today I noticed my oil drop a little so I checked the oil level it's down about 3qts it doesnt burn it. It's got a massive oil leak it's all over the front end when it's running it drips constantly but I can tell where it's coming from?

    Clean it off, then go to searching. Being a Cummins, my first thought would be power steering/vacuum pump.

    Cleaned it off twice but then it doesnt leak at idle when first started. Take it for a short drive just around the block and its everywhere again. Then its sits there leaking drops but you cant put head under it without getting covered in oil. Guess I could use a gopro mounted to the frame pointed up at it?

    Probably too shakey for a clear image.
    You could try the UV dye. Start low and work up.

    There is ultra violet die you can get at most parts stores. You will need to get a uv light and some yellow tinted glasses to see it. The die shows the leak like a neon sign. Just add the die to your oil and take it for a drive. They use the same kind of stuff for finding ac system leaks. The go pro idea isn't a bad one either.

    Did you correct the KDP “killer dowel pin” while you were doing the work?
