VSE Catch Can Overview and Installation on 3.0 Duramax Diesel LZ0 LM2 

Now that i actually have my oil catch can from VSE the issue has been finding time to get it installed. I have a friend who is a diesel mechanic for a Chevrolet dealership and he usually takes care of my Duramax needs at his house. After watching this video I'm thinking about doing this install myself. I just wish VSE had released their catch can before my friend installed the PPE charge air cooler I now have installed on my motor. I'm sure that there is some oil residue inside of now and it would be nice if there wasn't any at all.

This is what I’ve been waiting on for a while-thanks for the vid drop! Please post more with updates.

Phew, I gotta hustle and create a RU-vid channel soon. Placed an order for my equipment on March 14, still waiting patiently. Your channel is awesome, dude. It played a big part in my decision to purchase a baby Diesel - just love it. Interested in getting some merchandise, can you share the link?

keep us updated. i have very frequent regens. about 180-200 miles average. i do a lot of short to medium trips daily. 2024 LZO max trailer package. 5k miles.

Nice. Just need mine to get here now. As far as additives I use amsoil all in one every now and then. I can definitely feel the difference when I add it vs when I don’t. It runs smoother and quieter and has more get up and go.

Can't wait to get mine. I ordered the black one on the 8th and still waiting on it.

Got here on Friday and got everything ready today, Saturday, May 4. Whew, it took me more than thirty minutes. Well, it does look quite good. I sort of desire the black model you have rather than this silver, chrome one. I would love to get the same sticker that you've added to your catch can 😊❤

NICE setup, really like the quality of that unit and constant tension hose clamps - NICE truck!

Thank you for another great install video! I take all of your advice very seriously and I went ahead and ordered a pair of those pliers in anticipation of receiving my catch can. I’m excited to get mine and install it! I looked through my Idash, and unless it’s labeled differently I didn’t see a setting for monitoring the crank case pressure line that you were looking at on the laptop.

Great video! Waiting for mine that I ordered back in March with original 3-4 week lead time. Emailed them yesterday and was told I'm 168th in their order queue and may be an additional 4-6 weeks if I'm lucky. Bummer!

Interesting product and very informative. I know very little about diesel engines and puzzled by one thing. What drives the design requirements/philosophy differences of diesel vs. gas engines where the small gas turbos (in Ford or Toyota trucks and SUV’s) do not consume any noticeable oil even under normal towing situations and one never needs to add oil in between changes (at least as far as I am aware in an engine with no mechanical issues) but its pretty much a given with these Duramax 3.0 and other diesel engines? Hopefully you can shed some light on this for me as to why a gas turbo doesn’t consume so much or any oil vs a diesel. I just cant wrap my head around engines in this day and age using so much oil as “normal” yet very interested in this engine for my future purchase. As always, great content.

Just installed mine. Ended up going and buying the hose clamp pliers. Worth the price after trying with the wrong ones for an hour or so. The lm2 has wires coming off the battery that kinda get in the way but we shall see

Ready for mine! I noticed an increase of oil consumption at around 20,000 miles for whatever reason.

May 16, 2024 Update: After install started truck and drove out of garage and parked pickup, no issues. First drive was a 700 mile trip with my Rmax2 in my dump trailer from Idaho to Sacramento over the Sierra Nevada. Somewhere along the trip got a CEL. Banks iDash won't read or clear the code but in stored codes it shows P04DB. Checked hoses and I don't see any obvious leaks etc. and truck runs fine. Now that I made it to my destination I will have a couple days to check it out more and drive around without the trailer in tow before trip back over same route on the 22nd. May 13, 2024 Installed yesterday on my 2020 Sierra LM2. I was able to do it with new adjustable HF pliers no problem. The LM2 is a bit different as there is a power wire with silver heat reflective material inline with the hoses as they connect to the can. I cut the ziptie holding the wire to add flexibility and ran the wire between the hoses. At the back of the can there is a sensor in the heater hose that is close to the can when installed. I plan to remove the passenger side wheel and fender liner for better access and see if I can tie the hose away from the can a little to prevent chafing. Interesting observation, when I disconnected the stock hose from the turbo there was no sign of any oil. This is different than Greg's experience and my truck has 55,000 miles on it!

Been waiting for this!

Nice video. Only thing I would recommend is showing some closeups especially where that preformed hose connection is if that’s even possible. It looks like a really well thought out design. I wonder if the 1 psi bypass would eventually get gummed up with residue? Does VSE say anything about maintenance besides drain intervals?

Great video! Will this void my 30k warranty?

Here is what I need to know every body with diesels are always adding new parts to them?Im 60 years old and I want to retire with the next truck I bye.Ive been driving trucks for 38 years and I want a small hi-bread camper made 7000 pounds to camp with my grand kids Can the LZ0 in stock form not cost me a arm and a leg to get the job done ??

Love your video. Will get your catch can soon. I don’t know why lm2 oil temp (230f) is always hotter than cooling temp. Is that normal? Could you please tell me where is the oil cooler located? I couldn’t find the info anywhere. Thanks in advance

Thank you! Looks really a quality product! Just ordered one. Please talk about the p1006 code with the coolant flow valve issue. Just in my dealership had 11 on back order over 3 months. GM Doesn`t care. Under engine warranty waiting for the part over 2 months. I LOVE ---LOVED---- the truck . Was thinking to upgrade. Unfortunately won`t happen. Can`t even trade it in. the fan is in full blast. Found many on Ebay, but they won`t even install it! Its CRAZY! Please make a video about this issue! PLEASE! What should I do?

Thanks!

Take the advice in the instructions. Get the hose clamp tool. Frustration is a PG way to describe how you'll feel if you don't 😂 waited over 3 months just to be pissed off on my weekend

Quick question- my LM0 burns zero oil at 75k miles...do I still need something like this?

Still waiting on mine😂

Keep up the good work and thanks for your help demonwork

I get around 240 miles before a regen. Noticed on the I dash around 30% it shoots up to 50% right after. What do u guys get for distance?

How frequently do you have to drain the catch can?

Why would the manufacturer not build the motor with one of these and include the catch can as stock to the truck?

Is there any companys making a PVC rerought to atmosphere as that would be far more ideal

Awsome design

Can you just add extension to drain tube, leave drain valve open, and drain to ground all the time?

Is the oil accumulation a problem in emissions intact vehicles only or deleted vehicles as well?

now that you've looked at both vse and ppe catch can which do you like better? which do you believe would be easier for maintenance and ease of use? i plan on getting an 3.0 silverado with in the upcoming year and i defiantly want to add a catch can. your channel is defiantly going to be putting a dent in my wallet with all the stuff i plan o n ordering once i get my truck but they're defiantly necessary upgrades.

Is the bypass provided so that owners who live somewhere that the temp goes below the freezing level , dont have a bigger problem.?

im surprised there's a bypass in this setup.

Did the GM engineers design the engine to burn oil?

I want to add a catch can, but I was shocked at the price, it is at least 3x what I was expecting (which was twice what a generic version of the same thing would cost). FWIW The crazy blurs are really distracting...

Thanks for the video! Thoughts between this and the PPE?

Any idea as to when they are offered to the masses?

Super!

Does this mess with the factory warranty?

So does this help the oil burning and “blow by” I see when I remove my oil cap when running ?

Looking forward to your review after using the can for a while. A little off topic: you said you don’t use any additives in your fuel. Any particular reason? I noticed the GM manual recommends additives. This is my first diesel so I’m just trying not to mess up too bad.

Does it mount correctly on a 2023 lm2 suburban?

Hey, by chance, do you know if this is CARB compliant? Their website doesn't mention anything about the legality of it across the lower 48. California has some very stupid laws.

Anyone got anything about blowby? 2021 LM2

How do you drain it?

I recently received my catch can and I have a problem. There are no instructions for the LM2 only the LZO. The hose configuration is totally different than the LZO. Has anyone else found the installation instructions for the LM2??

Vse , what a scam!! Order 5 weeks ago contact them 2 weeks after ordering they say it will be 2 to 3 weeks before shipping, and now they say multiple weeks out with no date to ship, called for a refund no response. STAY AWAY!!

P04DB code with this!!!

Why don't car manufactures include this in a $ 40,000 vehicle ??

Are the LZO engines using oil? Burning oil? I am thinking about buying one,just don’t want to buy one that does that. My dually with a HO Cummins doesn’t burn oil.
