Engine: Wagner Adjustable PCV Valve

[ColoradoHawk]

There’s been discussions earlier about this PCV valve, and I just wanted to report to you all after buying one and installing it on my ‘63 GT Hawk.
I bought the valve along with the DF17INL inline adapter, so all together it cost $149. It fits perfectly where the original PCV valve went.

Even before I adjusted it it was working better than the one that I was using that was made for an AMC Jeep Wagoneer with no smoke whatsoever coming out of my breather caps at idle. Once I adjusted it, no smoke out of the breathers when revved either!!!!
It is a beautiful piece of engineering made from machined aluminum and I HIGHLY recommend it to all of you. It is worth every penny and you won’t be disappointed.

Thank you for your report. It's always interesting to get such a confirmation.
Nice day to all.

How do you meter the adjustment? Did you have a certain mark to hit? Did you have a vacuum, inches of mercury or water you wanted to reach or was this just a visual, no smoke, adjustment? At different engine rpm and torque load with vacuum differing how has this unit affected performance. How has this unit affected air fuel ratio, sparkplug condition, etc...

Just wondering if it is better than a stock unit.

At 15 times the cost of a standard valve I hope its better.

There are 2 adjustment screws, one for idle and one for cruise. The idle screw is adjusted by turning all the way in till it bottoms. Then you turn it out as many turns as called for on a chart based on engine size and amount of vacuum your engine makes at idle.
Cruise is set with a vacuum gauge connected to a port on the PCV unit. Initially, there is 0 vacuum at the port. You then slowly turn the adjustment screw in till 1-3” of vacuum shows on the gauge. Then you turn the adjustment screw back the opposite way until it shows 0 vacuum again and add 3/4 of a turn.
All the other questions I can’t answer yet since its only been on the car 1 day so far.
It’s worth every penny since stock PCV valves are no longer available, and even when I had one I still had smoke coming out of my breather caps. Now I have no smoke whatsoever. Plus, it will last basically forever since it can be taken apart and cleaned if and or when necessary.

Contacted these people today and asked them about a pcv system for a supercharged setup.
They asked for some engine info and some spec's, which were supplied.
Curious to see what answer they come up with.

Interested, my R2 has the original PCV valve which consists of a machined threaded brass body with a swaged-in check that appears to be a carburetor neoprene tipped float valve. I clean it periodically but not sure how to really test it to see if it's doing its job. I think it is designed to close when manifold pressure becomes positive under boost. I've never seen any blow-by or buildup in the breathers so I am ASSuming it's all good.

Jeff, let us know what the manufacturer comes up with for the boosted application. I'm interested in one also. Bill

Sounds like it could be worth looking into.

Thanks

It’s been a couple of years, how’s the PCV? Neal

I think the Original 01/18//2018 issue with Breather/Cap Smoke at Idle and at Speed was just a worn Engine or Valve Guides/Seals that the Special PCV Valve disguised by burning it and blowing it out the tailpipe.

Made an interesting discovery with it not too long ago. For awhile, I was just driving it a very short distance to work (2 miles) so the engine never got even close to full operating temperature. After a few weeks of this, it started idling and performing poorly. Took it off and it was completely gummed up with a beige-ish goo. Cleaned it and reinstalled and once again was running properly. Other than that, no problems.
