Still Not Sold On A Catch Can? Check Here...

JRaschke11 · November 22, 2015

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.

Nice catch ...I have the same results in about 4-5k as well

Nope. Not convinced. I'm convinced you could run the truck for 200,000 miles without a catch can without a lick of difference

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
