Did a trip this weekend. Left Saturday put on about 185 km and overnighted in Mont Laurier QC. Got up this morning (-17 Celcius) checked the breather vent line and fired the 'ol girl up. She moaned a little, but obedient as ever, she came to life. I allowed sufficient time for it to warm up in the parking lot before heading down the trail for home. Drove for about 2 hours and then she blew the dipstick. I caught it before the engine grenaded. Thankfully, we were close to a small town. Used one of the grizzlies in the group to tow it to a gas station. Had it happened deep in the bush, I know I never would have gotten it out. With the snow on the ground, and the STEEP hills, nothing would have dragged it. So it's off to my dealer tomorrow to see what the diagnosis will be. I want to have it looked at (probably a tear down is in order). A lesson to all the northern owners, when it gets really cold out, be cognizant of that and be careful - watch that dipstick! I'm not exactly sure what froze, but hopefully they can figure it out.
