I have the taller covers with baffle out to clear rockers. I put wristbands around my breathers to soak up oil but then I had oil getting pulled through the TB and down the Intake tube. I just got tired of cleaning up oil and realized for a NA setup its just not necessary IMO.

I put the baffles on my tall valve covers and they cleared my large scorpion RR. Helped out a lot.

I had an oil seperator, but it was still drawing oil. WHen I built the engine i knew I would put a pump on it, so I hooked the vacuum cleaner to the motor and listened for leaks, got them all sealed up. THen I turned off the vacuum, and let it sit for 30 minutes and it held the vacuum for that time. I think after awhile the sealants and some bolts holding gaskets just loosened up and let it have some leaks. The leaks let the pump draw air in and allowed more oil to be drawn into the pump. Most of the drag engines that run pumps typically don't stay together for several years and 30K+ miles.
THere are a lot of places where air gets sucked in, typically at the junction point of the heads/intake/block, around the harmonic balancer bolt, around the flywheel bolts, if the bolt holes on the crank go all the way through, through the dipstick tube where the dipstick sits in it, and the oil fill cap. THe fill cap on fox mustangs are two piece and it can suck air through that as well.

Ah, ok. More to running a vacuum pump than I thought.
I built this breather system a few years ago for my GT. The push on style breathers would always leak oil over the valve covers and eventually onto the exhaust. Not if I just pootered around but only if I'd give it a good blast through the gears. Works totally awesome.

I set mine up this way again yesterday. After test running it last night I have no issues at all, nor did I when it was set up this way before.
Here's my version.

I bit and pieced it together. I had -12 bungs welded onto the valve covers and the Moroso catch can. Then bought the fittings and hose to finish it off. They now sell catch cans with the fittings already on them but they were not available when I built mine. I modified the a/c accumulator bracket to fit the catch can. Made it look like it was supposed to be there.

hey guys i know this is a fairly old thread but the above pic is the same way i was advised to setup my 5.0 with a paxton and systemax efi intake .. i was told to block the rear pcv hole in the rear of the intake and just run large hoses (5/8 or bigger) hoses from the valve covers to a catchcan with a breather ..
how do you fill oil into the engine? i guess 12an is big enough to stick a funnel in and fill up.
im using factory ford cobra valve covers that have a metal baffle plate under the filler neck.. im trying NOT to modify the covers with any welding etc.. In my case, do you think using a valve cover grommet in the filler necks (with 3/4" ID) and push in a 90 deg heater hose size connector (3/4" OD) to plumb hoses to the catch can rather than using AN screw in fittings and welding etc.. ? or will this blow out?
like this
this way i can pull out and fill with oil in the filler neck.
I cant find a standard breather valve cover cap with a 5/8 or larger outlet otherwise id just get that.. they all seem to be smaller 3/8 and it was recommended for me to get something large (like in the pic posted above to the catchcans)
does that sound about right .. this means theres no pcv valve .. and based on some comments above how does fresh air go in? .. oh and i think i read with this system you plug up the pipe on the TB?
EDIT: just as i typed this and after a week of searching i found this:
http://mr-gasket.com/engine-componen...v-fitting.html
although it has a PCV fitting.. which i wonder if i could remove it and just use it as a standard breather and vent out via the 5/8 tube to the catch can .. this would fit well into my filler neck ..
