Adjustable PCV valve

Has anyone tried the adjustable PCV valve from M/E Wagner? If so, what benefits did you see. If someone has tried one on an engine with an aggressive cam, I would be interested in the results. Thanks, Chuck

I have it. It's a nice piece. I acutally see less oil seepage at various points around the engine. I wouldn't call my cam aggressive though.

I believe forum member "Bobby" runs an adjustable pcv with a cammed up engine. Maybe he'll chime in.

I had this and didn't see any benefits. Still the vacuum was sucking oil off the valve cover. I can let mine go for half the price if someone wants it. I have the valve and the original box with instructions and springs. Edit: I may keep it just in case so ignore this message.

I don't have one, but researched it a bit. You can use this in lieu of drilling the butterflies or opening the secondaries to bring in more air in a long duration/low idle vacuum situation. Perhaps an alternative to the Barry Grant Idle Eze kit?

Do you remember where you read up on that at?

c9zx,
408C, closed chamber heads. 10.4 cr. Edelbrock torker single plane and Quick fuel Brawler w 4 corner idle mix adjust.
Hydraulic roller .576/.588 224/[email protected] 110 Lsa.
15"hg @800 rpms and hot idle @ 13.5 afr.
Base timing @14btdc.
Will run a little more base timing when I can get a bushing made for my msd distributor or find a little better fuel.
Me Wagner does recommends using a pcv catch can with their valve, I did so and have accumulated about 1/2 teaspoon in my last 100 miles.
I like the valve and have made no mods. to the Brawler idle or transition circuits.
Edit 770 cfm/ vacuum secondary.

Thanks to all for the input, hoping for more. Boilermaster, click the link for custom bushings. https://4secondsflat.com/MSD Distributor Tuning.html Chuck

Thanks Chuck,
Glad that I took the time today to gather these specifications for you.
Nice to know one good turn will still warrant another.
hope to get these bushings soon

I'm glad I could help. Chuck

Yes. I posted a thread about my new engine with a rear main seal leak. Cleveland Crush recommended that adjustable PCV valve. I installed it along with a Moroso air oil separator. The leak stopped at idle and it leaks a little while driving. More adjustments needed. I needed to move the horn to the other side of the washer reservoir and fab some 1/4 inch bushings cut at an angle to offset the slope of the shock tower to level the oil air separator.

The reading was over several different posts when I was researching different causes for an off-idle stumble with holley carb. The Speed-Talk forum had some relevant info, as did racingfuelsystems. I opted not to get the tunable PCV. I tested different PCV valves using info found online along with the number stamped into the weight inside of the PCV to judge airflow. I decided it was more economical for me to drill the butterflies and buy an undrilled set if that approach didn't work out. So far, I'm happy with the drilled butterflies.

I have the Wagner valve and after getting the adjustment right I think it has helped my motor as well. I have decent size cam and not a lot of vacuum so the adjustment came in handy. I think they are a few old threads on here as well

Tnfastbk, In what way did it help? Idle quality, idle speed, light throttle acceleration? Thanks, Chuck

It seemed to eliminate the leak I had at the rear main seal after installation. Seems with the 408 kit that's a common problem leak. I think it reduced the internal crank case pressure. I used to have an oil smell during/after driving which went away as well. It could all be in my head but its been on so long now that I had forgotten about it until this came up. LOL
