Last week while ice fishing I was coming back to land about two miles from the truck , was going about 10 mph and the oil tank side blew off, sounded like a shotgun going off. Ended up ruining foot well when it went off. Shut down machine as soon as I could. Then turned machine to on position without turning it over to operate winch to connect to sled that would end up towing me to shore. However when I turned it to on position flashed HOT HOT HOT. was more upset about breaking down at moment, got atv into truck which was a chore. Go to take atv off truck and notice coolant in bed of truck on snow, pulled off truck and place in garage for night. Today took all plastic panels off did a compression test couldn't get past 56 psi !!! spark plug looked good and drained remaining oil in motor, which was nothing really. coolant tank before I went out was a min level on tank and now theres nothing in it!!! Not sure where to go from here besides getting a new oil tank !! Thinking leaking head gasket? any ideas ? Also drained front diff and tons of water in unit gonna rebuild it soon. Thanks in advanced for your help .
