    can anyone tell me the purpose of the 1/2" diameter hole on the left rear of the intake manifold between the last two bolt holes ? i have not been able to figure it out.

    It sounds like the return pipe from the air cleaner not in the photo above but there is a 1/2 pipe rthat runs from the air cleaner to the intake on my V-12 air cleaner. Lee Waldren Ft. Myers, Fl.

    You should probably try to find a way to utilize the vent. Had a similar situation with a dual carb sit up and was able to use a vent (hose) to one of the air cleaners. You might be able to install a PCV system between the vent hole and the base of the center carb? A "working" vent will eliminate blowby, help remove sludge and keep the fumes out of the cab.
