Default Clean exhaust evac

Has anyone tried going from the valve cover to a catch can and then Evac through the exhaust? The air pulled into the exhaust should be fairly oil free, right? Maybe combine that with a straight breather on the other side.

This is what I was thinking. I can do this, I wonder how good it would work Let me get this straight before I go off buying things. Basic catch , run the hoses from each valve cover into a T then run it to the catch can. Drill a hole big enuff on the top of the catch can and put a breather. Is that what you are saying ? I know I will have to plug off the intake,but thats not a big deal.

That sounds logical, What about this...

Metco breather on Oil cap
Manifold PCV plugged
PCV on back of driver and passenger side vented into the downpipe with check valves

That way... The oil cap just serves for the fresh air source, while the valve covers can vent all the excess oil and crap while the check valves keep the exhaust gas from coming back into the covers...

If this is a stupid idea I hope someone corrects me.

I am in the middle of my install. And if I can get a good solution I will do this. Just a matter of getting the right info.

Sorry, I am not a store, just someone who buys from stores.

The problem I had before when I tried to rig stuff up was that I did not have (a) fittings that the valve covers and (b) hose that fit both the catchcans and the covers.

I'm not sure about the evac pump, but john directed me towards the half covered breathers. It looks like they used Mr. Gasket Breathers and made a custom piece to fit the valve cover.

Well I have the Steffs oil beather tank and I think I will run two 1/2" lines to it. I think this is the very best way to do it. I would like to run a small line of the bottom of the catch can to the (pan).

Anyone know how I can run the oil in the catch can back to the motor?

This is a temporary setup I'm running on my built blown mustang engine. This is a very cheap but good alternative to a catch can. It is a air/oil seperator that you can buy at Home Depot. This one is a pretty big one called a Husky. It has a in and out line and works very nicely. Currently you can see that I connected it next to my power sterring resivoir. Cost about 20 bucks. I use them on both sides and have eliminated my pcv system completly. I had to have my tune messaged for no pcvs. I have mine just venting to the atmosphere, but You could easily send this line to the Mr. Gasket exhaust crank vent. Actually I'll probably do the Mr. Gasket setup by this spring.

well I had just used a 1" long piece of rubber tube (stock size I.D) pushed it onto the port on the valve cover then pushed the huge rubber tube over it. Very tight fit. Could ziptie it if you wanted.

Bought them at Pep-Boys. It just takes some trial and error, but you will get it figured out.

Well the two tubes to a catch can works so far! I am planing a smaller drain tube back to the front of the oil pan!
