Keep your valves clean / UPR Catch can install on my 2021 Sierra AT4 6.2L

[@CSltz]

I’m sure that I am way late to this conversation. But you will enjoy the steps that mount over the tires to help you get to the engine. So much safer than buckets. Steps have a tendency to slide also. If you get a the wrong angle.

[@Sober4277]

Its confusing when going to buy it cause it ask if u want the Billet Pro Series check valve? Or if u want the Billet one way crankase breather? Did u get all that?

[@KC-632H]

Got one for my truck works great so easy to install with the connectors👍👍

[@KnightsGarage]

UPR is really the best. They will last longer, catch more or and perform better for your PCV system than those other cheap ass cans. Glad you liked the video and the UPR can!

[@kevin-di9qw]

Get yourself a tire step, makes working under the hood much easier. Been looking at these, im gonna get this UPR one now...thanks.

[@KnightsGarage]

Thanks man. I’m going to look into that tire step!

[@simplespeed84]

What about the other hose from the other valve cover that also goes to the intake?

[@KnightsGarage]

That side sucks fresh air from the intake tube into the engine the direction of airflow dictates there shouldn’t be any oil caught there. Only thing you would get on that side is splash back maybe from the valve train but it’s pulling air from the intake into the crank case so I don’t believe it’s needed.

[@guyconnell2250]

Did you ever tow with it? I had one on my 2019 and it worked great until I towed a heavy trailer. I got 150 miles down the road and had oil dripping off the hitch, trailer, and all under the truck chassis. Had lost 2-3 quarts in that 150 miles. Disconnected it and hooked up the factory hoses again and issue solved. Prior to that, just driving around town and some highway all with no trailer, this catch can worked quite well. UPR was no help when I contacted them so I'm stuck with a very expensive system now sitting in a cardboard box.

[@KnightsGarage]

I have not but that makes no sense. I can think of no reason of why that could have happened other than maybe the check valve being bad keeping it from being able to properly vent the gas is from the crank case. Otherwise there’s no reason that a catch can of any manufacture would cause that. Towing with it really changes nothing it’s either seeing vacuum or it’s not Towing a heavy load does not change that.

[@berhardt17]

Great vid! I just got one for my 22 6.2 Silverado!

[@scott.h7352]

Same here, should be in the mail tomorrow.

[@johnaragon3314]

Trying to order this catch can. Did you get the larger check valve, the magnetic drain plug, and the 1 way crankcase breathet? Thanks for the help!

[@KnightsGarage]

Yes. I actually have this can I can sell you if you are interested. Message me on my Knights garage Facebook page if so.

[@johnaragon3314]

Am interested, don’t do Facebook. Is it a new kit? Same as the one you have on your 6.2? How much are you asking? Thanks!

[@KnightsGarage]

It is the exact can in this video. Pro series with check valve and magnetic drain plug.

[@michaelhack9716]

any hissing coming from the lines like the jlt is having?

[@KnightsGarage]

I didn’t notice anything I’ve never had a problem with a UPR Can. That’s not to say that a problem couldn’t happen because some parts are mass-produced but I’ve never had one and I hear very little negative.

[@KILLATENT89]

Just subscribed! I just got the same truck a few weeks ago and I had a catch can on my last truck. I was just curious as what options you got this can with so I can order the same. Thanks!

[@KnightsGarage]

The single valve can in black with the billet check valve. I have a link to the can I got in the description of the video. Thanks for the sub man!!

[@KILLATENT89]

@@KnightsGarage so nothing added besides the check valve?

[@KnightsGarage]

@@KILLATENT89 just that and the black powder coated can. I don’t do the drain line kit, extra o rings or clean side stuff.

[@KILLATENT89]

@@KnightsGarage thanks man I really appreciate it! And enjoy the AT4, I know I already am!

[@KnightsGarage]

I just looked and I don’t think I got the magnetic drain plug but I should have if I didn’t. But just because I’m really curious to see if there’s any metal flakes in there.

[@wesgouty7810]

Curious why you removed the UPR catch can? I was thinking about ordering one. Did you have an issue?

[@KnightsGarage]

Sold the truck.

[@s2k442]

@@KnightsGarage why did you sell the truck? Is there any reason to go with their pro setup?

[@KnightsGarage]

@@s2k442 I sold it because it was in the service department more than my garage. DRL turning purple multiple times, two trips for the HUD not working (had a part on back order when I sold it), radio randomly shutting off while driving, and i was afraid i would drop a lifter everytime i drove it. Pair that with the older looking interior and the fact I was able to my about 13k when i sold it and she was gone.

[@s2k442]

@@KnightsGarage I completely understand. I am thinking about a 2020 denali with 10,000miles that already has the factory cat back exhaust option from the dealer. Yes the lifter issue maybe a problem but not every truck has that problem. I guess its luck of the draw. Definitely want the catch can to help prevent GDI valve fouling issue. Pulsar AFM delete also would be on the list. Stopping lifters from even engaging can only help I would think. Then my head waffles back and forth with a ram limited with 5.7 non GDI but I just like the denali better. Sorry you had so many problems. What do you have now?

[@KnightsGarage]

The AFM being disabled through programming will not help. There are a boatload of people that I’ve had a lifter failures happen that had the AFM disabled since day pretty much, or at least had a disabled when the lifters collapsed. It’s a internal physical problem with the lifters themselves, and only taking those lifters out and replacing them will solve the issue. You are correct, not every truck is effected but an overwhelming majority of the 2020 and 2021 and even some 2022s are effected. Dealers couldn’t even keep up with repairs. I have a 2022 Explorer ST now.

[@johnaragon3314]

Is this the 6.2?

[@KnightsGarage]

Brotha, it literally says 6.2 L in the title of this video. Lol.

[@IG_Gh0st3]

@@KnightsGarage LMFAOOOOO

[@slagdemon]

Watched your video to see what lines to take off, but didn't want to pay so much for an overpriced oil container, so I went cheaper and got one off amazon for $25.00. There's no reason this can should run $200. It's ridiculous. I picked up a 2021 GMC 1500 AT4 also and now have 550 miles on it so figured I should get this on sooner rather than later.

[@scott.h7352]

$256 if you get the magnet, and the check valve.

[@slagdemon]

@@scott.h7352 I added a check valve and put a magnet in the bottom of my canister. 8200 miles now on it and it runs like it should.

[@scott.h7352]

@@slagdemon good to hear that!! I have 3000 miles on my 2022. I get to put it on Saturday.

[@kandaceknight4316]

It is a big truck. Glad you got it though!

[@KnightsGarage]

Me too!

[@Jason-pq5vg]

Nice job, does this void the factory warranty at all? I have a 2019 6.2L SLT with 17k miles i'd love to put one of these on mine. Thanks

[@KnightsGarage]

That just depends on your dealership and if they are cool or they’re jackasses that don’t know their ass from a hole in the ground. On another note nothing can “void” your factory warranty. They can only deny certain warranty claims because of modifications to the vehicle. But the Ketchikan does nothing to harm the vehicle they can deny a warranty claim because you put different tires on it and then what came on it is that gonna keep you from buying tires?

[@johnaragon3314]

What options did you get on it? Also, any vacuum noise? Thanks!

[@KnightsGarage]

Black can, and check ball on mine. No noises at all
