    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.

    As long as it was within 10-15 psi, I think it is,you're good....
