I heard the same which is why I purchased one, very inexpensive mod, first time I saw oil in it I said “it works” so that’s all that matters lol, my car is okay, but I need more power! Boost is coming soon!

Hell Dodge calls a quart every few months, NORMAL. Enjoy your catch cans, but they are not necessary in any way shape or form.

Not exactly. The benefit of a catch can on 6th gen V8 engines is primarily due to the impact of DI on the back of the intake valve. Over time, carbon will build up on the back of the valve to a greater extent than a port injected engine due to lack of cleansing by gasoline injected into the intake port. So, it is not about oil consumption by a DI engine, it is about limiting carbon deposits in your valve train. If you are going to dismiss catch cans as a "necessity" at least understand what purpose they serve.

They work until chevy uses it as excuse to deny warranty claim.. and then they dont work. Stragenly enough, Ford performance has OE like solution for GT350.


Mann makes a really nice one that can even autodrain! Plumb right back into the pan.

Obviously they catch oil. Agree the real question is are the necessary, beneficial, or harmful (other than warranty voids). Are there reasons the vaporized oil would be important to the top half of the engine (accounting for some top end lubrications, etc.), where eliminating it would be detrimental? I get that it will clearly cuts down on carbon build up - that makes logical sense. But are there any hidden costs of removing the oil that all us smart folks (but none of us GM engineers) are overlooking? That’s where my concern lies. I’d be all for it given the long term carbon reduction. That part is s no brained.

For those of you who’ve seen my posts, I’ve always got some left field concern. Feel free to mock at will 😋

Well, especially for forced induction engines, once you start pressurizing the crankcase the oil pushes past areas it shouldn’t then obviously ends up in the intake tract. This screws with the A/F mixture. Not good. Same with when you are pushing hard on a N/A engine. The catch can catches the oil before getting burned. Do your research. I’m a true believer there are benefits.
Why don’t the manufacturers use them. COST!!!
It’s more crap to put in the engine bay too. Another job for a person on the assembly line. Another company to have to hire to build them. They’re employed to manufacture them.
Do your research.

Ask yourselves this:
When engineers are creating the tunes for these cars, do you think they take into account the amount of engine oil that will be burned during the combustion process?
If so it’s a constant number and isn’t right. Why?
Because you can build 2 identical engines, identical clearances and parts and tolerances, and even those engines can likely burn a different amount of oil no matter how minimal. It’s still different even if one is burning a ounce more than the other over a 1000 miles
Now, think about mass produced engines and their tolerances. Catch my drift?
Catch cans are beneficial.
You have to empty them. You don’t, you’ll be into much larger problems and yeah at that point why would warranty cover you if you neglected the system that you installed and therefore caused the incurring damage.
The manufacturer wouldn’t be liable.

We use some of their filters on our equipment. That there is an interesting piece.

No, oil is not beneficial to be recycled back into the intake track. It is recycled back into the intake track like every other vehicle because the government told them they had to. That's it...
