I did an oil change today on my 09 arctic cat 500 4x4 manual today. After filling with 3.5 quarts of oil I see no oil in the sight glass checked for leaks none..when I crank it is see oil and water spinning around in the sight glass. I drained the oil witch had no water in it and replaced it with new oil didn't change anything. Before i messed with changing the oil earlier i stood the atv up on its rear tires to access the little oil pan with the drain plug because I stripped the drain plug threads by going the wrong way with wrench (******* I know )...So i changed that out droped it and filled with oil.Could that have anything to do with it and what should I do. Atv runs great just dont llike that milky look in the sight glass.
