    Catch can overflow

    I have a 07 rxt. Catch can is filling and overflowing after 10 minutes of riding under 5,000 rpms. I have no engine codes and ski runs fine. Anyone have any suggestions.

    its brownish in color. its a mix of oil and fuel. It pours to slow to be all fuel. Mods are x charger, rear air, intake grate, rrfpr, flashed ecu, stainless steel valves, supertech springs and retainers, 80 lb injectors. Fuel pressure is at 46 right now. Ski will only top out at 8400 rpms because i need a different prop.

    I checked the oil when it was cold before i went out and it was low on the stick (before the humps) i added about 12 ounces to get it in between the two humps. I rode to an island about 10 mins away from where i launch. i had my son with me so didnt get over 5,000 rpms. catch can was overfilled and oil inside hull. i checked oil on dipstick multiple times and it was at the second hump. i have no codes and ski runs good (actually think it could use more fuel). thanks for your help guys!!!

    Leak down was tested when I did his valvetrain upgrade, it was perfect. im thinking too much oil or its running rich.

    I trust and have seen chris's work on my own ski... like stated check the oil .. what injectors you running? an means of controlling fueling? or flashed ecu?
