With a set of snow tires, 911s make pretty good snow cars. I used to use mine to go skiing. A bit of a problem in really deep snow, as the floor pan can keep the tires from reaching pavement.

But take Red's advice.

I think the cam towers almost never leak. You follow the factory procedures to seal them on reassembly, or use any one of the other sealants folks seem to like and have experience with to back that up, and you don't get leaks there. You can put a dye in the oil which shows up under a black light to really hunt down a leak.
