Sportsman 700 coolant in oil

[anthony zimmerman]

Found coolant in my engine oil, I pressure tested the cooling system with oil drained and drain plug still removed, I found if bolt on mag side cover  that goes through the middle of the gasket on coolant port is removed antifreeze leaks out. Has anybody had this issues, is mag cover gasket leaking coolant into the engine oil?

That is the same side as the water pump correct ? If so then yes you would see coolant leaking into the engine if bolts are removed from that cover or if there is a gasket failure.

how do you check for coolant in oil?

[Frank Angerano]

@JacobSlabach if the coolant is pure and clean you will clearly see the green or whatever color coolant blobs in the oil.   If it’s mostly water then you will see the standard grayish color with some of the coolant streaks in it.  

There is also a pressure tester cap that has a pump connection on it to pump air into the system to pressure test it.
