I looked at that ad in popular science and it was very interesting. I also looked on ebay for one like it but only found a mechanism made by oildex. I will keep my eyes open for one over the winter, maybe Ill get lucky. Thanks for the great info guys....

Gary M: Fram called it a "Positive Crankcase Ventilator". If you Go to Google Books, you can find an original advertisement in Popular Science, March 1950, page 260.

The PCV system has to be carefully calibrated for the application. Otherwise it will interfere with the intake manifold vacuum, producing performance problems. Too often, it seems easier, and cheaper, to treat the symptoms instead of the cause. If you plan to drive the car extensively, it makes sense to fix it properly.

Well, I haven't seen one since I moved away from the old homestead 46 years ago, but I'll describe it as follows: The motor was small, about the size of a power antenna/power window motor. It was mounted to a small squirrel-cage housing about 4-inches in diameter, with a threaded inlet that mounted a metal screw-in filter cartridge about the size of a small coffee mug. The motor and housing were painted black, and the disposable filter housing was Fram orange with holes punched around the outside. The outlet was about the size of a heater hose, and led to a replacement oil-filler cap that was designed to hold the discharge pressure,forcing the filtered air into the oil-filler/breather pipe. The power was taken off the ignition feed, with an inline fuse so that the little blower ran whenever there was power to the ignition. The motor had a bracket that allowed it to be secured by one of the intake manifold bolts. We used these on all our cars and trucks, 9 wind machines and several other stationary units. In later years, Technically, this is called an "open system". Caterpillar in recent years developed a similar electric blower system that ultimately forced the discharge from the draft tube outlet back into the intake tract on non-turbocharged diesel applications, adapting the forced-draft venting to a more acceptable "closed system".

Well, as far as environmentally friendly, no car out there that was built before 1970 is. However, there arent many still on the road these days. I would like to look a bit further for that Fram power PCV system before I give up.Maybe Ill put a want ad in the v8 times. In the mean time if anyone hears of one up for grabs please let me know. Thanks....

MG, Did you happen to notice the Jamco instruction where it says to: "Make sure the hole in the manifold is cleaned of all sharp edges. Use a file or reamer for this." Ouch! I wonder how many guys would just blindly follow those instructions!

Gary: Like you, I searched for one just so I could show you what they looked like. I didn't come up with anything, and I'm sure no one makes the screw-on dry paper element today anyway. The lack of anything modern that is equivalent is because they were "environmentally incorrect". That is, they did a great job of cleaning up the leftovers inside the engine, and forced them out into the atmosphere. I'm not sure that the modern concept of forcing them back into the engine to be burned is environmentally better, but it is the "correct" approach. If you put one of these on a California car today, you'd probably have your "vintage exemption" cancelled, and have to install air pumps, cat converters and all the rest (just kidding). I only mentioned them, because they were a solution to the often overlooked issue of getting the baddies out of the innards.

Gary M., Click on this link: http://www.jamcosuspension.com/products/productID/1504 I'm sure this will be of interest to you and is probably what you are seeking......MG P.S. Be sure to click on the 'Downloads PCV4953 Install Instructions' at this site. Ooops - never mind. This kit is for an 8BA. But, maybe you could adapt it for your purpose.....
