I guess I need to elaborate a lttle.
You stated you have to go through the pass. That will put additional stresses on the engine. Which, when it blows will cause you to lose engine power. Which will then over-heat. Which will then spew coolant/oil all over the place. (Environmental issue) Now, you have a disabled vehicle on said mountain pass. (Dangerous to everyone around you)
Rick, before they go through the block they are very noisy. Most do result in block destruction in the end. More useless destruction. This is the stupid part. Rent a trailer or take Gloyale up on his offer. But, DO NOT DRIVE IT ANY WHERE!
