Elite catch can/separator. Both instilled properly.
Any advice please.

There's always gonna be some oil, but the clean side separator gets rid of more of it. I'm thinking if you want to help it some more, you could add an Elite Engineering check valve after the catch can and before the intake manifold.

If it is al LLT or older motor, pull the PCV and drill out the bottom two holes to 5/64".
Drill the TOP hole to 7/64"

I had oil in my clean air side till I did that. GM updated the PCV part in late 2013, with
the bigger orifices. You can other buy the new part, or drill it out yourself.

Thanks for the replies.
PCV done.

I`ll check I`m sure he has the Elite Engineering check valve after the catch can.

vs_pete · 07-26-2020, 02:06 AM

I`ll let him know.

'10CamaroDude · 07-26-2020, 03:22 AM

You really don't need the Check Valve... If you put a breather on that back port,
where that originally ran to, then that oil cap catch won't see any real pressure
anyway.

You may also have a problem because you used rubber hose on the PCV side.
It will collapse eventually, and probably does under load. There is a reason the
factory is all hard-line. Mine, is hard line for the PCV:

Clean side:

$18.00 Catch Can:

Using them on both the PCV and CLEAN side.

vs_pete · 07-26-2020, 12:18 PM

Mate would like to know there did you get the $18 catch can from?

eBay!

They have gone WAY up in price.

Both have the drain valve.

They were very well. The problem is, they're not as long as what they
are a knock-off of. So, with the drain valve, I attached hoses and ran
them to the bottom of the car, so I can open the valved and drain them
into a pan. Or along side of the road, whichever YOU prefer...

I found this:

You're gonna have to ask for OPEN pictures, because what they're showing
is not what the header/title indicates.

I hate this editor, I did NOT put all those spaces in. I continually have to EDIT posts
to remove all the double and triple spacing. NO other forum does that but this one.
I left it this time so show how STUPID it looks. I press ENTER once after each
line, and it gets spaced all stupid like that... THIS paragraph was edited... I have
to delete all those skipped lines... Piece of crap...

Thank you so much.

Adding a breather to the crankcase totally defeats the PCV system.

The PCV system is not a “vent system”, it’s an evacuation system designed to pull clean filtered and metered air in a specific path from the intake elbow through the crankcase to the intake manifold. Adding a vent to atmosphere defeats the system and can leave moist and/or corrosive gases in the engine.
Adding an oil catch can will help separate some oil out of the fumes before the balance gets to the intake manifold. But don’t add vents!!!!

AlanRubin · 06-25-2021, 03:13 AM

I DID ADD A CATCH VENT, no more oil out the clean side either.

The PCV pulls air through the clean side, via the intake tube, BEHIND the
air filter at idle, and lower engine speeds.

I added that breather catch, and it does not matter WHERE the PCV pulls the
clean air from, as long as it's filtered. VENT all you want, as long as there is
a filter on the vent.

Under high RPMs, the air also goes out the clean side. Well, not anymore, it
goes out that breather catch. It only vents under the higher pressure with
RPMs. As long as you keep the PCV side, you can add a vent to the driver
side. I have NO OIL in the fresh air line, NONE!

The car runs fine, no more bullshit oil in the intake tube, and no more
pressure in the engine. Couldn't be better.

The PCV system was ADDED by the EPA, it was ALL breathers at one point.
You do not need a PCV system, it's REQUIRED! Pull all the lines, and
run vents out both valve covers, and enjoy the 1970s era fumes... It's illegal
to use breathers, you're just brainwashed to think they don't work. Well,
that's your problem, not mine, so don't tell me how this shit works. Been at
it for 40 years, and I do what I want.

Gonna sit there and type like I don't know what PCV system is, when I was around
when they didn't even exist. Boomer..

Yikes! I did not insinuate that you do not know what a PCV system is. But your reply confirms that you don’t. Thank you for clarifying.
You can run a vent if you want, it’s your car. But to think that it does not defeat the system as it’s designed is wrong.
I was around long before PCV systems too. That just means we’re dinosaurs. It doesn’t mean PCV systems are bad.

AlanRubin · 06-26-2021, 11:42 PM

Never said they were BAD.
They're not a necessity, they're required by law.

Again, telling me I don't know what a PCV does. Fine, that's your ****in'
problem, not mine.

xstuntman · 06-27-2021, 08:56 PM

A bad PCV system sure can ruin an engine with premature wear and I think it's a crap design when breathers work and work well. Yeah, they are supposedly bad but they say cow farts are too so that gives some context into the idiocracy.
I did the PCV mod and plan on a clean side breather myself. From the folks I've talked to the oil being pulled thru the intake drops off significantly sometimes to zero.
