I have a 500 Sportsman with a plow on it. I was plowing snow and did not know that the ice had bent the oil line from the pump to the engine. Now the engine starts very hard and has a loud knock to it.Did I spin a crank bearing or mess up the cam some how? Has eanyone had this problem? Help!!! man with problems.

 

I would say if you had restricted the oil flow then you did the same thing as not having any oil in it. I would figure on atleast a crank. (and gaskets) Make sure you check bearings and oil pump gallies for grooves.
