I had one of those yrs back on my sb, but decided i didn't have that bad of a problem and just went back to open breathers. Mine pulled 3 or 5" of vac cant remember. It was just more wires and another switch. I understand that ford has one thats better than the GM pump. I'm going simple with this deal, open breather on one side and PCV valve on the other. Think i'll get some stuff ordered today.

Yes, windage try in use.

Your right, that would be alot of oil to suck up in 9 or 10 seconds, but when the oil is hot and thin I'm sure alot of it ends up at the back of the pan on the launch and with some trapped up top could add up. I'm using the Edelbrock victor heads and they do seem to trap some oil on outer cover rail. Combine that with a Milodon high volume pump and that could be a problem. I will be sure to watch that gauge on first couple passes. Wont have time or money to get the 4.30 gear and spool out in exchange for a 3.73 and track loc diff, so 1/8 is what i will be running for this yr. Running out of oil in 1/8 should not be a problem thou.

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!

I have some breathers with tubes on the way. Will see how they do.

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. Ron

Ok thanks Ron. I have some of those laying around. I ordered k&n open breather with black rubber top. Thought it looked better and maybe breath better as well. Oil level is lower with the install of the oil cooler as well. Doesnt blow nearly the oil now. Think i had a combo problem.

can you plumb a pcv into a 2 in. carb spacer or should it be lower, in the maifold.

As long as its below the carb its fine.

Mine's in mt Dommy adapter in ft. and my pcv and breather are both in the ft. one on each each valve cover..........

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.

A remote breather tank works pretty good on a street/strip type of engine. I wouldn't use on a daily driver since a daily driver should have a PCV, but the breather tank solves a bunch of issues on a hot street/strip car.

I use a Moroso remote tank with two inputs and drain. They are tall and skinny so you can stick them next to the radiator or on the inner fender.
