Re: Trick Flow Oil Can
you run an open grommet, no baffle on any type on the non pcv side? Right now I am getting no oil in my PCV valve or hose going to carb..but I am getting some smoke out the pipes. Never had this issue until I switch to these valve covers and the mroso grommets.
yes, I now run the stock Moroso baffle (no modification, stock 1/16" slit) on the PCV side (3/4" hole for the PCV). I run an open baffle (1" hole) with a breather on the other side. I get no smoke or oil out of the breather side, nor the PCV side. If I get the Chevelle hot, let it idle with my big cam, then, plug the PCV hole, after a while with a flashlight, I can see some oil vapor out of the breather on the other side. Once, I hook up the Wagner PCV again, there is zero oil vapor coming out of the breather side. This is an easy way to validate that your new Wagner PCV is set correctly and air is being sucked in on the breather side.
Note: with my old PCV, I was getting some oil seep around the grommets in both valve covers after flogging the Chevelle. That is all gone now, everything is dry. Now, I also realize that this leaking was telling me that my PCV was not the right one.
Regarding adding hardware baffles, I have the expensive black Chevrolet (lettered) aluminum tall valve covers, made in California. I took one off and inspected them for a metal baffle installation. I even bought a few metal baffles. Bottom-line, there are no bosses, so, there is no safe way to put a baffle in these valve covers unless you do a drill through. I refuse to ruin these valve covers with a drill through strategy...
