    pcv routing.

    I was fixing some leaks on my 69 mustang 302 and had a question on the PCV system.  I set mine up with the rear passenger side valve cover hose attached to valve cover to the air cleaner inlet underneath the cleaner.   On the front drivers side I have PCV in valve cover attached to the front vacume inlet on the carburetor.  I've had it this way for about 7 years but haven't put a lot of miles on it.   Is this the correct routing?   Should I have the PCV on the rear passenger side valve cover?  I do get the engine fumes in the car while driving and smell like fumes after driving the car.  Which makes me think its not correct.

    Thanks

    Sounds right to me, as long as the connection on carb is on the large port on the manifold.

    It's easier to add horsepower than it is to lose weight.

    You smell like fumes? That's not good. You sure it's not a overly rich condition and/ or exhaust leak issue?

    Re: pcv routing.

    Well now...I have mine from the pass side to the base of the carb flange(under the carb) The other vc has a vented filler cap. I feel the blow-by/fumes are sucked thru the engine(from the driver side vented cap) into the base of the carb by way of the PCV. There ARE a couple of ways to run it....this is just mine.
    IF you have a mod-ded up engine then possibly a PCV valve from a Hi-Po 289 would be better. Or even one from a big blk engine. They are NOT all the same.

    Not a lot of fumes.  Just smell like a carb after driving it.  I checked the plugs and they look good.

    So it sounds like it doesn't matter if I have the PCV on the Drivers side or Passenger side as long as I have it enclosed on both ends.

    Re: pcv routing.

    Ford always put the PCV valve on the passenger side and the air inlet on the driver side.  I do not know if it makes any difference, but may have been simply to shorten the distance the vacuum hose had to run since all the OEM vacuum ports were rear of the carb.  If your carb has the port on front, then it makes more sense to run the PCV on the driver front.  But, WHERE do you pour in the oil?  Normally that is done where the filtered air intake is located on the valve cover.

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.

    I just pull the PCV out and use a funnel and pour the oil in the valve cover.  
    Thanks for the info!
