I did a few hundred miles with mine on and drained it out. As I expected the mixture is about 90% water and then a touch of oil skim/fuel. My intake was clean before install at 15000 miles so this is exactly what I expected.

My dealership said my catch can wasn't needed and wouldn't catch anything. I opened it in there shop after 2,000 miles and let it run on the floor. Lol

So, I added a second output fitting to my Original RX catch can. I had been emailing with the RevExtreme folks about the benefits of a dual output can, and they were gracious enough to send me the par

Correct. The mix is (depending on the outside temps as the colder, the more water and unburnt fuel):

 

Water

Sulfuric Acid

Unburnt fuel

Oil

Ash/soot/carbon

 

And the rest is smaller amounts of different hydrocarbon based compounds.

 

Found out myself the same way with a solo cup! I use empty water bottles myself.

Does anyone else have oil residue forming around the intake port of the catch can? I've noticed this start to happen recently. The can still seems to be functioning properly otherwise. I'm not sure if maybe the black hose is just aging a bit and the oil seeps out a bit....maybe I shouldn't have put a hose clamp around it and just let it attach to the barb without the clamp.

 

I have an original RX if that matters.

Is it just me or should there actually be 3 separators on the 6.2L?

 

I see one from each valve cover to the intake and one more from the valley cover to the intake. Are most just joining the valve cover breathers?

Join the 2 valve covers together and then replace the valve cover oil fill cap with a clean side separator and hook it to the air intake. I have E2-X on my 6.2 and that's how they do it with them..... or the 5.3 as in that regard they are identical. The 5.3's just have their pickup from the factory PCV in a different spot which is towards the rear of the valley cover where the 6.2 it's right on the front.

I used thread sealant on the threaded fittings and hose clamps for all the barbs. I think not a tight seal is all that's the problem on yours.

Same, I had some yellowing/browning of my pipe tape on the exit fitting actually. Had to take it off and redo it as I was getting a slight smell too with long idling. No issues now.

10-4 thanks for the input. Like I said the can still seems to be functioning properly. I do have clamps on the barbs but I think the oil is working itself past it anyway. It's not much....just some residue on the top of the can and you see it on your finger if you run your finger over the top. But it's not like it's dripping everywhere or an excessive amount. I notice a little residue around the port at the crankcase probably from oil in the hose flowing back down the hose and leaking out around the exit nozzle after the engine shuts off. Again there isn't a lot here..just some shiny residue. I have 27,000 miles now and I put the can on around 11,000. Assuming it doesn't work, I'll probably go to about 75,000 miles and then take everything apart, clean the can, and change the hoses.

So I think I put my catch can on backwards I'm not 100% sure. The vacuum port in the front area of the engine should be the outlet and the one on top of the valves should be the inlet right ?

Front of engine goes to input on can (center port). Output on can (outer port) goes to intake port above valves.

Ah I appreciate it. My can is just backwards so I put them in the ports they were closest too.

I did the same thing with mine (not an Elite - it's the Conceptual Polymer unit) - it could go 180° in either direction. Of course, I picked the WRONG direction, and had already cut my hoses to fit. I didn't notice the lightly etched "VAC SIDE" in the thing until I had it all mounted up.

 

This is why, if you look closely, you can see a 4" section of hose that doesn't match the rest, right near the unit. Had to extend the hose to make it work. Wasn't happy, but not a real big deal. Can barely notice it.

Buy a new piece of hose at an auto parts store. Think i paid like 5ish bucks for 6 feet.

Yeah, sounds like it. If you want to send a picture, we can verify the hose connections and direction.

      07 yukon xl 6.2 stalls at hot idle and wont restart

      By Jsdirt · Posted

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      2027 GMC Sierra: Official Discussion

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.

      from another thread   Update...although the truck sometimes seems to idle weird and the transmission shift a little weird, I've driven about 7,000  miles and no issues.   However, the way GM has handled my rental reimbursement, the situation when my truck quit, and the recall in general has led me to this point...I have driven a GM vehicle for the past 46 years and unless I buy a C3 Corvette, this is the last GM vehicle I will ever own.
