Just found out about catch cans

[bk2drvr]

How many of you guys run them? I’ve got an 18’ Sierra with the 5.3. Should I get one?

I have one on my wife's Camaro and cant believe how much oil it collects.

I would leave your new truck alone.

What would a catch can be. Asking for a non mechanical friend lol !

I run duals on my mini cooper (one boost side and one vacuum side) and one on every thing else I have. Anything direct port they're a necessity as no fuel flying past the valves leads to buildup thats only removed via walnut blasting the backs of the valves by a professional. They remove a *LOT* of moisture, dirt, and oil. I suggest them to anyone that actually wants their direct port to last more than 100k.

I have one on my ecoboost, it’s amazing what it catches, fuel, oil and water. For direct port injection it’s a must as your valves will thank you! It fills up in about 3-5k miles

Thinking about one. Is that a McNally unit by chance ?

 

[Bpracing1127]

No it’s the upr mega catch can with clean side separator.

 

[LakeBeard]

How much?

 

[Bpracing1127]

Mine was 400 bucks

We run the Jaz set up with the little breather filter on our Spec racer Fords. Are you guys running one side vacuum and one side sucking in blow by? I don't see a vent on your examples?

 

[Dana757]

I have one on my Subaru and my boat. Also make parts for these guys. https://www.mightymousesolutions.com/catch-cans

Did you just go with the universal kit?

They go back up to the pcv to vent

I ran a separator made for an air compressor on my blown expedition. It caught a ton of oil/water.

These catch cans seem pricey for what they are, but prolly gonna get one for my ‘15 Silverado.

I went with the single outlet can without the clean side separator.

Select GM Truck 2014+... from the drop down menu.

Two questions:
Are they CARB legal ?
Do they adversely affect your warranty ?

 

[Sleek-Jet]

We call then air/oil separators on airplanes.

Not something I'm worried about on my car.

If they run a vent it voids nullifies any benefit from drawing a vacuum via the PCV and the car will suck in unmetered air and will mess up your fueling.

Carb legal, no. A smog guy may freak out if he saw it. If set up properly and in line they do nothing to emissions, and won’t cause any check engine lights.

I run an open system on the LS1 in my race car. No PCV system at all, a -10 line from each valve cover, and a -6 line from the valley cover to a baffled, vented can.



I went from pumping this much oil into the can in a 30 minute run with the stock PCV system. God knows how much the engine sucked in and burned up.

To this much in 2+ hours with the vented setup, with no chance of the engine sucking it back through the intake tract.

You can see the vented catch can with the filter on it in the upper right, bolted to the shock tower. This was before I added the 3rd -6 line to the valley cover.

I run a Moroso can on the wife's 6.2. I think it was like $150.00. Does the job but doesn't look as fancy as the ones you guys have.

I have that one on my CTS-V. Simple, discreet, in line and easy to hide.

 

[Bpracing1127]

You wouldn’t believe what I catch in mine. With direct injection there is no gas to clean the back of the valve so that stuff coats and sticks to the back of the valve and stem.

The forced induction in your truck overwhelms the PCV system, and the oil drainback to the pan from the heads is probably too slow.

The problem with LS engines is the drainback is too slow and it hits the spinning crank, creating oil vapor and mist and high RPM.

Is it necessary for direct injection or port injection? They are 2 different locations for the injectors. I do not know of any manufacturers using both port and direct injection systems on the same engine.

Lol I meant direct injection haha

 

[bk2drvr]

I keep my trucks a loooooong time so this probably makes sense for me.

Is there any performance benefit to these? No one mentioned this. Seems like there should be?

 

[Bpracing1127]

No performance benefit, just a cleaner running engine

 

[Chili Palmer]

Are diesels good candidates for catch cans?

Lexus and Toyota have run port and direct (google D-4S injection) together on many engines for over a decade [emoji106]

I know for sure Lexus no longer does DI-only on any engine.

Ford started offering it within the last few years also.

Might have to look into adding one to my supercharged Tundra.

Ford introduced both direct and port in 17' for the Ecoboosts and for 18' the 5.0 is included.

Great addition on my duramax for the last 250k miles. Saves the exhaust y bridge and turbo vanes nice and clean and not getting filled up with goo epoxy coat oil soot looking crap that turns rock hard.

Don't need a can on a diesel, but removing the tube is a great idea.

 

[sintax]

I used to run one on my LS engine in my GTO. Its amazing how much oil those things retain, that was destined to roll right into the intake tract. You'll likely fail the CA SMOG visual portion if the guy knows whats going on, but typically these things take 15-20 min to install so its not too bad to remove it every couple of years.

As far as diesels go, you are also right. I never did the PCV reroute on mine, I wish I did years ago when I blocked the EGR at 3,000 mi.

Since 100,000 (I've got 212,000 on my truck now), I disconnected the 3 electronic connections from the EGR, so hopefully that has helped some. Where does the PCV reroute drain to, a catch can?

I'm sure it depends on the truck, mines an LBZ duramax. They plumb it out onto the ground, but you could certainly use a catch can to be more eco friendly =)

My 78 harley is the same way, crank case breather runs out a hose, and dumps under the bike.

Mine's an 11 LML. Looks like I'll have to do some PCV reroute research.

got mine last week for my 6.2L i already did the valve cover swap and will be installing the can asap

I ran my hoses down to the frame rails. A little residue would be on the ends. Never had stains on my driveway.

Tuning alone will disable EGR. Blocker plate ensures it stays closed, but it is not completely necessary.
