    Water on the Rave Valves

    Hi All,

    I'm not sure if water on the rear cylinder rave valve is a normal thing or not.

    The ski runs great with no problems, Compression is good and even in both pots.

    I had the ski connected to the hose whilst flushing it and straight after I decided to check the raves to see how clean they were and noticed water droplets on the rear pots rave.

    I did run the ski for 10 seconds after I turned off the hose.

    It was only on the rear rave valve. And it was covered in thick milky oil from the water.

    is this normal? or do I have a major issue with a leak somewhere.

    here is a few pics of what I mean,

    You have a leak unfortunately,either a head gasket or an exhaust manifold gasket
    The oil should be black (from combustion) and no trace of water at all
    I would pull the head first and carefully pry it off with a flat blade screwdriver under the lifting tab areas and see if you can see any traces of water marks past the gasket
    If it was mine I would pull the manifold as well and change it over with OEM 03/04 XP DI gaskets as they are harder and dont leak as often
    On 2 / 951s skis I have had the cylinder liner leak at the head surface from rust forming between the aluminum and the steel liner and this did the same thing but usually its the head gasket
    Report back and tell us what you find
