on my car i will be running a line from each of the valve covers to a catch can (possibly 2 line from each)
ill plug the pvc valve.

my car isnt a daily driver, more of a weekend car / street car, si ill probably check/drain the catchcan once a month (when i change the oil)

i didnt mean to sound snotty, i thought you were referring to the actual catch can, not the filtration.

 

I want to run -10 lines from each valvecover to a catchan and plug the PCV valve all together but I am worried about air ciculation in the crankcase?

 

Kelly you weren't snotty. I understood you. It's just nerve wrecking trying to figure something out that works.

TA/KID what would you plug the PCV up w/? I know the vac line can just be capped off but what do you plug the pcv line up w/? Weld the port shut? I myself like some sort of filtration that's why I'm just using that setup.

 

I'm using this.

There are two issues we face that have to be addressed with the PCV system.

1. Ventilation of the crankcase to keep harmfull moisture and blowby from getting trapped in your crankcase and causing premature wear.

2. Removal of pressure build up in the crankcase from blowby and high rpm's that causes leaky seals.

If you are simply running two -10 lines from the valve covers to the filtered catch can then you are not addressing issue #1. That system would work well for relieving pressure build up but will leave harmful contaminants in your crankcase and oil.

I would leave the stock PCV hose/valve in the drivers side intake manifold to get rid of all those contaminants when your in vacuum.

 

So basically you're stating that the best set up is to have an inline oil seperator before the PVC valve and to have a catch can/breather/exhaust vaccum to vent the valve covers?

Yes, that filtered catch can seems like a great idea for the breather tubes. I've tried breathers screwed directly in the valve covers and it makes an oily mess and smells bad. If the catch can was placed above the valve covers most of the oil would drain harmlessly back into the valve cover.

I would however not delete the PCV line. I would just put an air/oil separator in the pcv line that that goes to the manifold so you can reduce the amount of oil that gets sucked into the intake manifold.

 

-B definitely keep the pcv in place and just use what 97WS6Pilot and everyone else on here has suggested w/ the oil/water seperator.

97WS6Pilot do you know how much oil you were blowing out the breathers? Not concerned w/ the oily smell but the oil all over the bay would get old I'd imagine.

 

As you know a little oil goes a long way as far as a mess. It would drip on the valve covers and then run down on the headers and smoke. I even tried putting a breather on top of the oil filler tube and it still dripped. I have a lot of blowby due to larger ring gap on my car so this may not happen to everybody.

 

Now when you mention a filtered catch can to the breather tubes Im assuming you're talking about connecting the both valve covers via some braided line and into a catch can thats vented/filtered to the atmosphere?

Or would the morso kit that uses the exhaust as a vaccum on the valve covers be more efficient?

-B what you described would be great too as long as your Cal smog folks don't mind.

The moroso kit would provide a vacuum source so you would not need the PCV valve/line in that case. You would however need a fresh air intake of some sort.

 

...and the confusion continues.

Ok if you put a straw in your drink and seal everything up when you suck on the straw it is going provide vacuum but no ventilation. If you pop a hole in the top of your drink now you have ventilation.
