PCV Oil Seperator (Correct style of "Breather") DO NOT DELETE | AnthonyJ350

We install an oil separator for or 2005 Chevy Silverado with a 4.8L V8. There are a lot of videos out there that tell people to delete their provisions and run a breather. That is not recommended because you may send false readings to the MAF sensor as you're letting unmetered air into the engine because you're bypassing the MAF. Watch the video where we show you can keep the PCV system closed and still be able to remove oil from the system to keep your intake manifold clean.

Nice!

[@ericg1149]

Clean setup, I was just thinking about running a 2nd catch can for the passenger side as I am trying to solve the issue of oil being sucked into my intake to the throttle body

[@AnthonyJ350]

Thank you! You can definitely do that if you would like and have the room. The throttle body side only gets used under W.O.T.

[@isaiahodum7071]

Drill extra oil drain holes on the inside of your valve covers. Be sure to shop vac and blow all the metal shavings out before reinstalling. Crazed Performance channel has a decent video on it.

[@robertpaul3675]

So then I wouldn't need to cap off valve cover port just run oil cap seperator and valve body port to a T barb but then putting a inline filter before T barb on valve body side then both would go to the T then into the TB breather port or would this cause problems?

[@AnthonyJ350]

This video might help kzbin.info/www/bejne/n4TdhmCZq9F_hZo

[@robpaul7900]

Is it more beneficial to delete my valve cover outlet and cap off my valve cover port? Is this more effecient? I have a 2001 5.3 vortec. Does this change anything in the working of the engine?

[@AnthonyJ350]

No because you can eliviate the pressure, the engine won't be as efficient and the piston rings can't seal as well. The PCV system is actually really good except for it puts oil vapour back into the intake.

[@robpaul7900]

@@AnthonyJ350 ok I have same setup as you did in this video. I worded it wrong I just meant to ask does it hurt anything by how you cap off valve cover and use the oil cap instead? It seems to be running very clean so far and runs good.

Would it be better to run a T barb and run valve body port and elite seperator to it then put a one way check valve or inline filter then leafing to breather TB port?

I would run an oil catch can on the dirty side of the PCV system and this breather cap on the clean side.

You can, this was just easier to install.

[@JCM111]

@@AnthonyJ350 yea I’ve been over thinking it. I don’t want to barb the intake pipe. I’d rather catch all the gunk and route to the intake

[@aarons.5523]

Serious question- Is it possible to use 2 oil separators (1 for each valve cover) and plumb it so that when the crank is in a vaccum it uses the air from the tbss manifold connection on top for metered fresh air into the valve covers BUT when at wot and crank pressure is building it reverses air flow and uses both oil separators before forcing air into the tbss manifold connection??? The separators would obviously need to be able to flow both ways and am wondering if anyone has ever tried this or something similar to upgrade theier pcv system??? Any input on upgrading the pcv system over stock would be great 👍 thx In my mind this is still metered air from the intake that could go into valve covers through the that could be used for high vacccduring higbut also allow for reverse air flow into the intake when

[@AnthonyJ350]

I've seen dual separator setups, but most are separate circuits like I have on my truck because the flow stays exactly how it was engineered.

[@sammydelph7459]

Can you make a video on how to install the barb fitting into intake tube

[@AnthonyJ350]

I'll try to if I ever do an install for someone.

Can you use this for a ls carburetor swap🤔

[@AnthonyJ350]

That I'm not sure if this is still effective.

[@lylegoodluck]

Will it be ok to connect the fresh air hose to a vacuum line? Or does it have to be in front of the throttle body???

[@AnthonyJ350]

I just replicate how the manufacturer does it.

[@seangowan7441]

[@AnthonyJ350]

Do you have a link?

[@gregmf9427]

Why would you send back into the intake? That defeats the purpose of sending oil back through intake?

[@AnthonyJ350]

This side of the PCV system only really does anything under wide open throttle. The separator keeps the oil under the valve cover, but allows pressure from the crankcase to go somewhere.

[@jewllake]

I have that set up in my 2018 Sierra. Be careful with the double 0 rings. The metal lid fits too tight on the plastic and the 0-rings get cooked and brittle and they break off and could fall inside the valve cover. I sanded the hole in the plastic larger and only use one 0-ring instead of two. The cap sits tight and still seals well. You can buy a packet of 20 high temp 0 rings at home depot to keep as spares once the original 0 rings get old and crusty.

[@AnthonyJ350]

Ok so just keep an eye on the o-ring that seals to the oil neck connection?

[@AnthonyJ350]

Mine only had 1 o-ring like the factory oil cap. Yours had two?

[@jewllake]

@@AnthonyJ350 yes, when you pull the metal breather off the adapter plate that threads on to the filler neck. They are two 7/8 x 11/16 x 3/32 #13 0-rings. Danco makes them under part number 35730. I bought a package of 10 at Home Depo for a few bucks.

[@AnthonyJ350]

@@jewllake Ahhh ok, what's the best way to separate the assembly?

[@jewllake]

@@AnthonyJ350 Just pull straight up on the metal cap with the barbed hose fitting. The plastic adapter that took the place of the oil cap stays in place. That's how it's supposed to work. On mine the tolerance between the two was too tight so i sanded the opening on the plastic adapter larger. Otherwise the rubber 0-rings were being stretched and twisted and would break apart. Fortunately none fell inside. Probably not a bad Idea to replace them every other oil change.

[@sydney_nicole]

Oh and emissions testing for me either

[@AnthonyJ350]

Do you have a catch can system on your vehicle?

[@sydney_nicole]

AnthonyJ350 no I don’t it might have had it before the motor was swapped from a 04 Chevy Tahoe

[@tomjw7]

So the oil cap thing is the breather and ur sucking in unmetered air , is that what I'm seeing here ?

[@AnthonyJ350]

It's after the MAF so it's metered.

[@tomjw7]

@@AnthonyJ350 it's not metered tho. Ur sucking in air after the maf that doesn't go past the maf at all, therefore it's unmetered. U have a vacuum leak. Unless that port has a check valve in it that stays closed under vac, but then it would be pointless and ur not actually pulling in fresh air for the system to work properly.

[@AnthonyJ350]

@@tomjw7 OK watch this video. Everything on this Nissan 350Z is setup like factory. There is a factory vacuum hose under the intake that goes to the valve cover (no check valves) and it's after the MAF sensor and its for the PCV system. kzbin.info/www/bejne/fHyck4Okm7p8i9Usi=HNnNXhXqjV__BfIA

The cap isn't a "breather" it's sealed.

[@AnthonyJ350]

You did see the thumbnail where I say it's a "closed" system.

[@jayjwin1178]

this is a wrong way. oil vapor will make shortcut and go into the air intake. if you want to solve oil vapor getting into air intake side (before TB) during WOT, just put another one way valve in between.
