did a compression check on the engine and 1 cylinder was a little low. I don't remember the numbers, but it was slightly lower than the other 7. the engine overheated once, real hot! should I be concerned about this? hopefully I'm just loosing a little power and worse gas mileage. Will this lead to a complete engine failure soon? I don't want to be stuck in NorthDakota winters with a dead engine middle of nowhere. that happened to me once in the fall and it wasn't even that cold and we froze our asses off.
