    I have blown the gasket between the solenoid and the base. I cannot get the electrical side torque screws out no matter what i tried. Used heat penetrating fluids of several brands with heat. Hammer, heat and oils. They just will not budge
    500$ for a new one is pretty steep. Anyone try an aftermarket one?? Or using parts from each to make an “oem” style??
    Oem #25710-31022 or can it be blocked off without triggering codes
    So more research shows it is an air injection check valve

    The torque screws will not come out so i cannot replace the gasket. I was thinking buying a cheap aftermarket valve for 100$ drilling the tops of the oem screws off then mounting the oem electrical parts to the aftermarket body. If they will work together
