    Where the hell is all this water coming from?!

    During Moto 1 on Saturday during the Jet Jam race with about 2 laps to go I took a right hand turn and I lost all RPMs. Got it back to shore and after some investigating I found that I am getting water in my PTO cylinder. I have the Riva girdled heads so I tore them apart and it looked like the O-ring between the head and the dome was slightly damaged. I did no have another one so I put some RTV in there and let it set over night and hoped that it would be good enough for one more day of racing on Sunday. Well, I don't think that was it cause I was still getting water in there.

    I have since replaced that O-ring, put a new exhaust manifold gasket on the cylinder and pressure tested the cylinder. When I took the PTO pipe off it was FILLED with water. I have an air leak somewhere. I am out of ideas. Where could I be losing this air? I assume that is where I am getting this water from. I have sprayed soapy water and windex all over the outside of the cylinder and I do not see any air bubbles. It is normal for the cylinder to slowly let air out?

    I did find a hole in the pipe but that was on the outside. I did not put a hose clamp back on right and it rubbed through. I should get the pipe soon from the welder. I will retest then.

    I am starting to think that stock my not be all that bad....

    Sounds like the base gasket is on upside down.

    Now that is a possibility. I just replaced them. I will check it out this week. I am in Phoenix all week so I will have to wait until I get home Friday.

    Thanks guys.

    I had to get the pipe welded due to a small hole on the outside (a bad installation job on my part). I am going to re-pressure test it when I get it back.
