Since I don't like to assume, do you have splash plates in the valve covers under the breather holes?
I run two K&N breathers...one on each valve cover, plus a line from the back of the manifold to the standard
oil separator on the firewall...just some mesh in the plate. There's a line running from the top part of the old lawn mower gas tank down to the frame to exhaust the vapor, and a line at the bottom to let any
oil drain back to the pan....standard Cobra BB fare back in the day.
No pcv valve...never could figure out why folks like to splash
oil (even wet vapor) on their plugs.
That's on a big damn 482ci Shelby running a big damn cam with my big damn foot in it most of the damn time. Works damn poifectly.
Now, you can go ahead and reinvent the wheel...but the original round ones still roll the best.
