Flipped, now melted..... why?
Hi all, This April, on the last trip of the season, my brother flipped his sled in a creek bottom. it sat upside down not running for about 1/2 an hour while we dug it out. After starting it and ridding to the trail, the check engine light came on, and a compression test back home revealed that the engine was indeed in need of a rebuild. I can find no other explanation besides the problem being caused by it sitting upside down. Is this possible? And is there a way to start them to stop this happening again?
