I had a PCV valve on my Belvedere. Had oil leaks after a pass down the quarter. I went with the electric vacuum pump, with a catch can before the pump. Eliminated my leaks!

Ok Cab. This is the pan i bought from you. Thought you said to use 1/2 qt over pan capacity to avoid sucking pan dry thru 1/4? Thought it was a 8qt, nope its a 7qt. So you say to use 6qts? May be main problem with oil pushing out with high rpm. That looks like the same Moroso pan I use and I run just 7 qts in it. My dipstick reads full with 7 qts in the pan. I use a standard PCV valve in my pass valve cover and a breather on the drivers side. The hose on the breather nipple is open and draws the air into the crankcase as the hose just goes down under the brake booster and I loop it once and let it point to the firewall. I did that in case the breather would spit any oil when racing as I did not want it to spit oil on my valve cover but it does not get any oil even in that hose. My valve covers have a nice working baffle in them since no oil seems to ever spit out of the breather I use. It works great on the street as my eng pulls enough vacuum that the PCV system works fine driving on the street and I have no problems or oil leaks when I race. But I don't race alot as its only been about once a year lately. Ron This is a better pic of the breather as its just a standard breather used on some production cars but it works fine for my setup.

Overfilled oil: Accidentally did that on my '79 Chevy 4x4, thought for some reason it was a 6-quart capacity instead of 5-quart. It doesn't see RPM, mostly just runs into town on occasion & shoves a plow around in winter, but there was oil coming out of it everywhere, even a puddle of accumulated mist on top of the air cleaner & finned M/T valve covers I added for humor. It runs factory breather & PCV. This in addition to the traditional SBC habit of weeping oil at every seam, mind you. With 5 quarts, that extra rustproofing stopped. It's a Targetmaster crate deal, not too many miles, previous owner did that some years back.

M/E Wagner...Great PCV valve. Got one for my 440 6 bbl that was blowing oil out the breather. The PCV valve I got when I changed from stock valve covers was just one that "fit" my new aluminum fabricated VCs. Just because it fits doesn't mean it's right. M/E Wagner PCV valve is so good I'm getting a 2nd one for another car.
