    GTX 155hp - water in oil

    I have a 2002 GTX that I just discovered has water in the oil. I changed the oil and ran it on the hose for awhile and the water is back in the oil. The coolant level does not seem to be going down. Anybody have any ideas?

    If it was a headgasket wouldnt the coolant level drop??

    Describe how it looks or post a pic. Is the oil just black?

    You have a IC in your intake? Coolant overflow still look nice and neon green?

    I dont think so.. its the 155hp. So that means no supercharger which would be no IC?

    I did read a lot of threads before I posted.. water in oil is a IC problem normally. I could not find anyone with water in oil on a 155hp ski..

    hmmmm I don't know man unless it's cheap oil breaking down but it wouldn't happen that fast. Pull up the cooling diagram for your ski and look where outside water routes

    Also it does look like someone had the engine apart at one point (I could tell by the intake bolts - the 6-point head on them def has had a wrench on it.) No clue why or when.

    No sure if a gasket was not installed right and started to fail or?

    Where can I find the water routing diagram?

    More than likely you have a pin hole leak in the oil cooler, or the seal at the water pump/thermostat housing is bad
