Question Pcv Valve On Fe - - Help - -

HEY GUYS,

I WANT TO INSTALL A PCV VALVE ON MY 427 S/O.

I HAVE ONE "S" VENT ON THE BACK OF THE INTAKE MANIFOLD AND A VENT/OIL FILL TUBE ON THE FRONT OF THE INTAKE MANIFOLD.

OIL VAPOR IS ESCAPING FROM THE FRONT VENT/FILL TUBE AND BEING DRAWN INTO THE ALTERNATOR. THE BEARINGS DON'T SEEM TO MIND BUT THE BRUSHES GET REALLY UPSET. I WANT TO RUN A PCV FROM THE FRONT FILL TUBE TO THE CARBS OR INTAKE MANIFOLD OR ANYPLACE THAT IT WILL WORK.

I HAVE TWO HOLLEY FOUR B'S - DOUBLE PUMPERS; NO SPACERS; AND I CAN'T FIND ANYPLACE ON THE CARBS TO CONNECT A PCV HOSE. THERE ARE "PLUGGED" PORTS ON THE PASSENGER SIDE OF THE INTAKE MANIFOLD THAT (I BELIEVE) GO INTO THE FUEL MIXTURE RUNNERS ON THE MANIFOLD, ON THE DRIVERS SIDE THERE IS ONE PLUGGED PORT IN THE CENTER OF THE MANIFOLD.

I HAVE BEEN TOLD THAT IT'S NOT A GOOD IDEA TO PLUMB THE PCV LINE INTO THE INTAKE MANIFOLD BECAUSE IT CHANGES THE FUEL-AIR RATIO BALANCE BETWEEN THE CYLINDERS.

ANY THOUGHTS, SUGGESTIONS, HELPFUL HINTS, ETC. WOULD BE GREATLY APPRECIATED BY THE UNDERSIGNED - AND HIS NEW ALTERNATOR.

THANKS VERY MUCH - - AND - - Y'ALL HAVE A REALLY GREAT DAY.

BLACKJACK
