1952-59 Ford Newb PCV question

If all goes well, I'll be turning over the engine in my '55 this weekend. One thing left to do is figure out how to hook up the PCV with the "Powered By Ford" valve covers I plan to use. Both covers have breathers and one of the breathers has a ****** on it. Should I be using that ****** to connect the PCV in line with the port on the front of carburetor? There is a picture in my album showing the side of the carb and you can just barely see the breather in the bottom left corner of the picture.

Sorry if this is a silly question. I looked around on the main board but didn't find anything that was similar.

Thanks for the help and I'll be posting a video if we get it turned over.

Good question. I put a PVC valve in my new valve cover on the right side of my rebuilt 302 and hooked it to the front of my edelbrock carb. But I am not sure if this is correct? I ***ume the carb ****s blow by gases out of the crank case this way. Is that how they work?

 

PCV ( positive crankcase ventilation ) is a simple concept. You are evacuating the crankcase of vapors, blowby, etc by the intake ( vacuum ) of the engine at the intake, through a PCV valve, AND replacing them with clean, fresh air, usually through an oil fill cap with a filter element on older engines, or from the clean side air ( after filter ) on the air cleaner ***embly. Where you connect to the intake is usually at the carb spacer ( at the rear on most Ford engines), perhaps on the carb, but BELOW the throttle plates. Connecting to a vacuum port on one of the intake runners is not good, because the crankcase vapors will not be equally dispersed to all the cylinders. The PCV valve should be one from an engine similar in size to your engine or the OEM one for your engine as they all flow different amounts and also flow differently at various engine vacuums. The fresh, incoming air should come in from the opposite valve cover if the PCV valve is valve cover mounted, or the front, if the valve is installed at the rear of the engine. This will cause the entire crankcase to be ventilated.

 

This is what Ford used with those valve covers http://www.ebay.com/itm/Chrome-Brea...Parts_Accessories&hash=item23162eb780&vxp=mtr

 

There you go. Smaller fitting is PCV valve to intake or carb spacer, larger fitting usually went to fitting on side of stock air cleaner. Aftermarket air cleaners may or may not have a fitting for it. If not, you'll have to fab.
