PCV valves

[Rex]

Dear Group,

I am a new member from NC. My Mark II is a California car, and it has a PCV valve installed where the valley pan air intake vent is just to the side of the oil filler. Is this a good thing or should I consider going back to the original ventilation system.

I would also like to know if anyone has a good pair of used wiper arms for sale? This car has some replacement arms on it, and they are too long, causing the blades to hit the top of the windshield.

Finally does the group keep a list of known serial numbers for these cars?

Best regards,

Maybe your blades are just too long. The Mark II came with really short blades due to the vacuum wiper motor not having as much power as an electric motor. I think the stock blades are only 12" long, or less.

A PVC system is a good thing, It'll keep the bottom of your car far less oily and you'll be doing your part for the air you breathe. Adjust properly, your carb should be able to compensate for less filtered air and more recirculated gasses. Unless you're showing the car in LCOC events for authenticity, it won't matter.

I'm thinking about doing mine in a way that's nicely concealed. I would seal up the valley vent and the draft tube bottom, use a cap on the oil filler that has a hose stub welded to it and vent it to the air cleaner. Can I mount it to the bottom of the air cleaner? Are PCV valves position oriented?

Dear Barry,

Thanks for your reply. On my car, the vent in the valley cover has been replaced with a cap and vacuum port with a vacuum line running from there to the base base of the carburetor with the pvc valve in between. The breather cap and vent pipe are still functional. It's not really obtrusive looking.

My father used to own a California 62 T-Bird and they removed the vent pipe from the back of the intake and placed the PCV there. As the crankcase fumes exit the engine through this tube,from the air rushing past and drawing the fumes out and the fresh air entering the vent cap (with a filter in it) I would use the vent tube. You have to have fresh air entering the crankcase (the vent cap) and since they installed it (the PCV) in this cap, it will now pull the air up through the vent pipe. Alot of North American cars used a filter cap(or a hose to a filter in the air cleaner housing) in one valve cover and a PCV inserted into the other valve cover.

I would like to avoid drilling a hole in that bit of jewelry.
