I installed the Elite Engineering catch can on my 2015 Denali 6.2 the first week of August with only 100-200 miles on the engine. Since then I put 5000 miles on the truck in the first 30 days when I drove it all around Michigan and then to Missouri to Colorado to California. Had the oil changed around the 5000 mile mark the first week in September after I arrived in California. From September 1st to November 21st I put another 1100 miles on it. I don't drive a lot out here.



The only performance mods on the truck currently are an AIRAID synthetic dry filter in the stock housing, AIRAID intake tube, and Borla ATAK catback exhaust all put on about the same time as the catch can in the first week of ownership.



Here are some photos of the catch can after about 6000 miles.

I have never heard of a catch can before. I can see it obviously catches oil from somewhere but could you please explain the purpose of it and what it is plumbed into?

Thank you.

People have 200, 000 plus miles on their trucks including my 04 sierra without one or any problems

Your '04 engine didn't have Direct Injection...

Hey, I recently installed the new Elite E2-X catch can. I was looking at your post and the impressive results you were having with it. My question is, when you connected up your hoses to the existing pcv ports on the engine, did you force the the rubber hose over that "barb" that the old pcv factory line latched onto? I just butted mine up to the barb, not over it, and used the supplied spring clamps that Elite sent. Just curious on what other people are doing for that.

Some people just don't get it.

 

Not only are you washing oil down the intake to coke up the valves but direct injection also makes for some dirty oil.

 

A catch can and early oil changes will make for a very happy motor.

Your '04 also has gasoline to wash the oil down the intake and off the valves...

Keep in mind you would have had 3x as much oil in the catch can if it wasn't for the extreme miles and long trips, short trips and cold weather make for tons of oil!

I asked Fondupot the same question, I have a 5.3 with PCV side of manifold , I just pushed end of hose to the barb, if it breaks you will need a new manifold

You ain't necessarily as bright as you think you are.

 

Condensing oil from air in one spot doesn't necessarily mean you are getting more than a negligible reduction from the remaining oily air that is still passing thru your intake valves. All youve paid for is that warm fuzzy feeling that you're making a difference. But none of us really know, because NO ONE has ever done a real experiment to compare two identical trucks driven identically (one with and one without a catch can) to see and measure the difference of intake varnish buildup between the two.

 

Also, changing oil early is a waste of money. I've had oil analysis twice confirming this fact. Followed the oil life monitor and changed after 7500 miles. The oil came back with excellent numbers in everything and still had life left for Blackstone to recommend pushing interval to 9500 miles.

 

Better use of your money (instead of the catch can route) is to seafoam/crc right before you change your oil every time.

 

Evidence of condensed oil quantity is not sufficient proof that your intake is any cleaner than folks that don't do anything at all.

So youre saying that pouring out half a bottle of oil from the catch can proves nothing? youre saying there is no proof, but a half a bottle of oil not going back onto the valves inst enough proof for you. I mean after all you stated the above poster isnt as bright as he thinks he is, yet I am seeing heads with 35k miles on them with valves looking like a neglected bbq grill after a long summer. Im also seeing 4-8 oz of oil being caught before heading back into motor. seems sufficient enough for me that we are at least prolonging the bbq grill look

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.

      Oil Consumption

      By PunchT37 · Posted

      1/2 qt over full ain`t gonna hurt $h!t. Most times, a whole qt won`t either. Most have windage trays now. As long as the crank isn`t slapping itself in the oil, it`s not the end of the world.   We used to overfill 1 qt at the track, at race time. Better to have it over full than having the pan sucked dry at 6500 rpm`s.
