My new 2014 Norge developed a leak right after I bought it. I thought the same thing, head gasket. Took off the plastic shroud(three screws), there's a breather plate under there up high on the back of the cylinder, held in place by two screws. That's where mine was leaking from. Ordered a few o-rings for it and replaced it myself. The original had a nick in it where it had been pinched during assembly.Easy job. You might check there first. Good luck.
