Well, I have the infamous oil leak from the rear head on my '13 XC. Twice now, I have wiped up oil from the top of the transmission case and from the fins under the exhaust port on the rear head. Closer inspection and it looks to be either a head gasket or the porous head issue. Snow is flying now, so spring I'll find out what the dealer says. Kind of leaves a sour taste in my mouth...haven't even put 1,000 of my own miles on the damn thing and I am seeing leaking. I guess the silver lining is that it happened before my warranty is up in June.
