Dual-Flow PCV valve for modified engines..
Anyone here used this PCV valve on your engine? You can tune this valve with a vacuum gauge, it has adjustable idle and cruise circuits. It is also rebuildable. Anyone used one yet? Check the enclosed link, thanks...

Wow! Nice find. Never heard of it, but had thoughts about something better than the traditional PCV valve. Wonder if it will work good enough to keep some rowdy street engines from having to run a vacuum pump? I have been fighting with pulling oil through my valve cover mounted PCV. Had to ditch the All Pontiac aluminum valley fan for a stock valley pan to fix it.

Will be watching to see if it has any merit down the road.
Will also pass-along the link to our PCV Tech Specialist and maybe he can test one or two of them against production valves. Tom V.

I saw an ad for those and was curious about them.

You mean your dial calipers? Did you help design these?

More interested in this study vs the dual PCV design work:" PCV Valve Baffle vs. Oil Consumption Test Study" http://mewagner.com/?page_id=1221
Decent Camshaft (for the size of the 302 Ford engine): Comp Cams hydraulic roller – .565″/.574″ lift, .232/.240 duration @ .050″ Poor Design Baffle = 1 quart of oil every 600 miles of driving. Improved Design Baffle = 1 quart of oil every 30,000 miles of driving. The Improved Design Baffle reminds me a lot of the factory Pontiac baffles over the Rocker Arms (that everyone removed) when they "got rid of the factory crap" under the valve covers. Pontiac Engineers did stuff for a reason! Tom V.

Went back on and now it's changed. No, not involved otherwise they'd be "Shaker PCV's" Cool product & would like to see what Tom's engineer has to say.

Tom -Edelbrock's 409 dual quad originally placed a PC in the back of it with their baffle-siilar to the one in their first picture . Sucked oil -they now changed it and use it to hook to the air cleaner for the fresh air for the PCV system.

Skip, With the majority of the time in PCV (Vacuum mode) can see the Edelbrock thought process but a crappy design for separating oil will still have an issue under "PUSH" conditions, (High crankcase pressures) back to the Air Filter (before being sucked into the engine to be burned). Duty Cycle is just a lot less in "push mode" vs "pull mode".

That's why we have the Tomahawk valley pan so we can run street cars with proper baffling that doesn't suck oil and not have to use a 50 year old valley pan full of crud. Wonder if this new PCV valve will fit into a Pontiac factory valley pan grommet.

They also have an inline adaptor that uses a 3/8 rubber hose on each end of the valve and you can mount it anyplace. If you save your back issues of HPP they show the valve on page 69 of the June 2013 issue...

I was going to order the Tomahawk valley pan, but pulled the one from my 52,000 mile '71 350 and it was very clean, so I used it. The older pans need no clearancing for rollers. On the subject of pcv in valve cover, they better have a very good baffle system and likely still will not work as good as stock valley cover. I tried many different set ups on the valve cover with no luck. Sure the poor drain back characteristics of the e heads don't help any! After a drive with the stock valley pan, I pulled the pcv and it was bone dry. Have not run the car hard yet though.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
