Where the OP has the valve installed (on the block directly behind the valley pan opening) is incorrect. There is neither a splash shield under the valve or any type of separator above the valve. The valve install will continue to draw excessive fumes/vapors into the intake tract and foul earlier than preventative maintenance will catch.
