So nobody with a catch can wants to post pictures of their valves but are 100% positive that theirs are in better condition than non catch can engines. Got my laugh in for the day

Looks aren't everything. That is why the world is full of ugly people still.

Interesting video. I've seen others of his and they're very informative. Next I would like him to explain how you look like you are 25 but have grey streaks in your hair [emoji3]

 

Looks to me it’s proof that it’s beneficial to use a Catch Can. It’s totally up to the owner of the vehicle, may be easy for most to mess with it but some just want to drive it, later trade it for next model but I personally am using Lucas Fuel Treatment literally in every full tank and since I’ve been using it I’ve noticed zero issues. Do I think there will be zero issues down the road? Who knows, but till I notice any issues I’ll be using it along with Amsoil Signature Series 100% Synthetic and changing every 5K miles.

 

My wife’s 16, 5.3 SLT Yukon XL had rough idle caused by carbon build up under 20k miles and dealership wanted to charge me $300 just to pour in their special fuel additive so I declined and started using Lucas Fuel Treatment, never had any issues after that. I don’t know whether I’ve got carbon build up but the one thing which is for certain: Truck has 20k miles on it with ZERO issues which personally I contribute to using Lucas Fuel Treatment since I’ve bought the truck brand new. Btw, due to kids now older, getting their own cars, flying is the new necessity, the Yukon XL has been replaced by a couple new BMW’s lol

soooooooo anyone with a can please post a pic for comparative reasons.  This is not a challenge truly curious to see.  

Yes it is :D and a good one. 

 

I want to see the one that looks better than the one submitted without as well. :thumbs:

 

And then the explanation of what benefit there is between two.

Many members here do not have a catch can and are well over 100K on their non K2 trucks without issues.

No disrespect to those of you that run a catch can and i encourage anyone to follow with what makes them the most content, but the

question remains. If this carbon buildup is such a problem long term why do automakers not include an Oem engineered Catch Can setup from the factory?

Is it an extra cost issue or that engineers feel a catch can is not a crucial component to the longevity of an engine?

 

Or GM doesn't want your engine to last 300k+ because then they wouldn't sell enough parts and trucks to turn a handsome profit?

I've got 52k miles, only run E85, don't drive like my gramps. No misfires or anything. Never run fuel cleaner or catch can. If I was keeping the truck long term I'd probably get a catch can and clean the valves (if needed) but I've decided to sell the truck in a few months.

E85 is a very clean burning fuel, as a matter of fact I bet your valves are in excellent condition but for those of us that don’t have E85 capabilities, we’re stuck with all sorts of ideas lol

It’s because it’s a maintenance item. It will fill up and need to be drained and the bulk of the people out there wouldn’t do that. Hell they probably wouldn’t even know their automobile had a catch can at all since most people don’t read their owners manuals.

I got the truck with 30,050 miles so I'm not sure what the previous owner used. 22k with me and only E85. I am curious how it looks but just not worth my time now that it'll be gone soon.

You’re going to sell your truck and share one vehicle between the two?

That's right. I work nights and work 3 nights one week and 4 the next. She works part time on weekday mornings after I get home from work. If we end up needing a 2nd car I'll get a beater, or make her walk to work since it's only 1.5 miles away :D

all these videos of "do catch cans work?" and they all show what its caught it a weeks time.  Im not saying that doesn't convince me because i am already going to do it on my next truck regardless.  But what really needs to be seen is intake valves on similar mileage vehicles with and without catch cans.

That’s bs 

Imo not bs, if it freezes and blocks the pcv it could blow the rear main seal.

 

How could you sell a truck with something like that, in which a solid 20% of the country sees temps low enough to freeze the 90% water mixture and clog up the line.

      A/C failure cause???

      By Somethingclever_2014GM · Posted

      Glad it worked for you. I tried that 1st, about 2 years ago. Didn't help. I also tried doing a hard reset (disconnecting battery for minimum of 30 minutes). Worked a couple times, but after one summer of doing it over and over, that no longer worked.  I was fairly confident it was either the compressor or a failed actuator, but I just couldn't identify which one. Had to research which actuators do what and which last numbers are associated with each.

      Took me FIFTEEN MINUTES to find this. Isn't that a problem? On the mainstream media I can INSTANTLY find 100 articles bashing President Trump ... but when it comes to TRUTH in American corporate news & search engines, it's carefully filtered to support ONE SIDE. A Republic cannot survive like this! Incredible! Even all the AI searchers out there failed as well! ChatGPT said it needed more details on the video that I provided a DIRECT LINK to! I thought AI was the be-all, end-all?? I had to dig it up myself. This should be FRONT PAGE NEWS!!! 🤬   Here's the statement directly from our President:     Glenn Beck's reporting on the operation:   https://glennbeck.com/watch/videos/trump-just-revealed-a-massive-military-secret-that-lowered-gas-prices   In case that link doesn't work, here's the YouTube link:     And another 15 minutes to find this clip out of Glenn Beck's video - the first few seconds is all the corporate media will allow the public to see, since the low IQ people will think Trump said " I love inflation ", and that was the end of it. Taken WAY out of context! Here's that part, plus the 2nd part about the oil smuggling operation:

      Another 6.2L engine failure!

      By KARNUT · Posted

      More is cylinder deactivation. Kia-Hyundai Ive had 4. The warranty is the same 10 years 100K miles. My grandson drives the first one 05 Elantra GT. My wife drives the second one 2011 Genesis. The Genesis still performs as new and looks great. The Elantra looks rough. He’s not kind to it. The third was a Genesis coup. The fourth was a Santa Fe. Those were my daily drivers. I don’t keep them long. Kia is the same as Hyundai with the same warranty. I looked at the K-4 today. Too small, otherwise pretty good buy. Most of Hyundai and Kia’s have a performance upgrade.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.
