ME Wagner adjustable PCV valve

[tortuga]

I have one on my ford racing 427/535 stroker along with a morosso catch can. I drain a bit of oil from the catch can every drive. I removed my carb at 10,000 miles and the inside of the manifold and the intake valves (by horoscope) all look better than new...great system.

The valve has merit, and in combination with a Moroso or Stef's air/oil separator would be a good system.
I run a Moroso on one of mine, no oil in any hoses.

I have the ME Wagner PCV valve, and the Moroso "small" separator. As we all know, or should know, if your carb suffers from the "hot idle" blues, the cure is not to open the primaries up deep in to the transition slot, but rather to open the secondaries up a little at idle. On Holley carbs with the little screw under the base plate, that's a PITA. The Wagner valve is nicely adjustable so as to allow you do something similar to opening your secondaries, thus allowing additional fresh air (as fresh as crankcase air is, I guess) without opening up your primaries and botching the fuel/air adjustment. I do both (cracking the secondaries and utilizing the Wagner valve) and it works very well. Here's a pic of the installation. Plumbing it in with a Turkey Pan requires a little bit of effort, but not much.

Patrickt,

That is a very clean install. How often do you empty the separator? I'm assuming it has to be removed to be emptied.

My valve cover is nicely baffled underneath the PCV outlet, so not a lot of oil gets sucked up in to the separator to begin with. The separator unscrews in to two parts, with a rubber O-ring between them, since it has to be air-tight. I think most of us would get by with a once-a-driving-season dump. Now, be advised that you'll see a vacuum drop at idle. I went from about 12" down to 9" (both with and without the oil separator) when I went from an off-the-shelf PCV valve to the Wagner. This valve, along with cracking my secondaries open just a bit so that I can have my primary butterfly down at the bottom of the transfer slot, really makes my idle nice and reliable even with the hottest of under-hood temps. Before doing all of that, I would occasionally have to "heel and toe" the throttle at stoplights, on really hot summer days, after having run her hard. I no longer have to do that at all.

Thank you for the info.
