    Blow-By Valve Check for Sea-Doo PWC

    The blow-by valve allows crankcase vapors to return in the intake system where they are burned. Blow-by valve hose check is part of the standard 100 hour service (or 1 year) for most Sea-Doo personal water craft.

    blow-by valve 4-tech gtx

    Can anyone tell me where the blow-by valve is located and/or the part number? I get an error code that it is closed. Also, is there any way to open it or a fix? I have a 2003 GTX 4-TECH... Non-turbo. Thank you
