Have you used one, and if so do you figure it is worth the $?

I bought 2 from their website. One for my turbo 4.6 DOHC jet boat, I'll find out when it gets warmer how that works. And one for my 496 stroker that hopefully this summer will be on the road, then find out on that one. I don't think there are any retailers for them. The price on their website is the price.

They have a website. It's a tunable pcv valve that can be tailored to an engine's requirements.
Edit: originally typed egr valve for some reason.

Probably would not stop rough idle unless it was caused by the PVC system.
The main advantage is you can tune the amount of PVC operation at idle and at cruise.

I looked on their website. Claims to stop oil leaks, keeps the engine cleaner. Might increase vacuum at idle and part throttle. Also, forum and club members may be eligible for a discount.
I ought to buy one.

Not sure what "Pushrod" was disagreeing with, but here's the gist. The PCV, positive crankcase ventilation, was designed to do a couple things. 1st, to keep the crankcase vapors out of the environment to some degree and the oil slick down the center of the highway, and recirculate it back to the intake to be burned. A byproduct of that is that while the engine is running at idle and cruising speeds, 90% + of the time, it pulls a vacuum on the crankcase. So air comes in a breather and the engine vacuum pulls it out through the PCV. This vacuum helps keep from having positive pressure in the crankcase. A positive pressure "can", not "always", cause oil leaks. Supposedly each PCV valve is tailored to its specific engine. So theoretically they will not perform optimally on a modified engine. The Wagner is tunable. There have been magazine articles on this product, all with good reviews. There are many opinions, "if it's built right. If it's tuned right, it wont have any leaks and doesn't need a PCV valve, just 2 breathers". That is their opinion and I won't try to change that. For my engines, I like the idea and am hoping I have good results with it. As for the turbo jet boat, I'm also installing a vacuum pump for when the engine is under boost to help with the same issues, leaks and ring seal/blowby.

PVC is a good thing on a street engine for many reasons that are all well documented.
There must be a reason every car manufacturer has exclusively used the PVC system for around the last 50 years. If manufactures could do away with it and save money they surely would.
I have a Wagner valve on my 340 engine and it works fine.
I find engines without PVC the oil gets dirty quick and they are smelly.

Great product from a great family. Father is the machinist, son the engineer , I think it is the mother answers the phone. Gene ,the father answers any and all questions and is a pleasure to do business with. I am a distributor but I had to promise gene that I wouldn’t sell cheaper than him.

Yes, a good thing but the reason the makers use them?
They are required by law!

I always like to run a PCV system on my street engines and I run one on my 493 in my 63. I actually had many PCV valves around as I have ben an auto tech since 1974 until I retired on disability on 2012. But I found one that works fine on my 493 as it pulls enough vacuum through the valve at idle and the car idles great and no oil leaks. The PCV valve will flow the most at about half throttle when the vacuum starts to drop some as then the spring pushes the valve open a bit more and it will pull more from the crankcase. At idle the high vacuum pulls the valve farther into the opening closing alot of it off. Then at WOT when the vacuum drops to about zero the spring will close the PCV valve. It will also close on a backfire so no fumes are pulled into the intake if the eng backfires. But I have found my PCV that I am using works very well on my eng and I honestly dont see me paying $130 dollars for any PCV valve when I can make one that I have work. I do agree its a good PCV valve since its adjustable for engines with lower vacuum but I myself wont be buying one. Ron

I'm thinking about it after reading @andyf comments on lg cams and efi
Andy would this work instead of filling one with epoxy and drilling it out?
Thanks
