So I see people talk about BT oil catch cans, or just people talking about oil catch cans and I'm wondering what exactly do they do? kind of a dumb question I'm sure but I am just wondering their exact use?

I just bought one myself. I have no idea how well they work but we will see.

Anyways, to sum it up a little: There is oil that goes through the PCV valve and back into your intake. The catch can is put in series with this line so the oil is caught in the can and not directed back into the engine. Think of it as a accumulator in a compressor in the garage. It is designed to catch the water so it doesn't go into the motor. Fluid goes in & only air comes out.

Different type oils have varying vapor thresholds.

What this means is that depending on the point the oil goes from liquid to vapor determines how much oil...and water is going to end up in the catch can. Think of it as boiling point of the oils.

The best way to think of it is like water. At one temperature it is a solid. At typical temperatures above 32 degrees F it is liquid. It remains a liquid until it hits vapor threshold and at 212 degees F it goes to vapor.

It then gives off it's "latent heat" and turns back into a liquid and runs down your windows in your house etc.

So likewise, oil "volatility" reacts to the refining heat that comes from your engine and goes from a liquid to a vapor and while going up the tube gives off the latent heat and turns back into a liquid and condenses into your catch can....leaving the fuel vapors and combustion byproducts to go back into your intake, burned and out the exhaust.

The best benefit is it stops oil from collecting in your intake manifold and causing knock retard.

I always thought those were common in just Corvettes.

 

[Fudge]

So are these thing needed, or recommended?
I've thought about getting one myself, but have mixed feelings about it!!

 

[AdWo2187]

I think heavily recommended for Hemi's. I emailed diablosport for a custom tune and they wouldn't even do it if I wouldn't have had a catch can.

X2. But if you get one, PLEASE remember to check it frequently. I check mine every 2-4 weeks.

While I was getting an appraisal at the Dodge dealership the manager took my car for a test dive and after that opened the hood. He asked what is that, (pointing to the catch can), so I told him what it does. Then to my surprise he said “why don’t all the cars come with them? “ After my acknowledgement he then said “Oh, that would make the car last longer.” So, yes it Is an added benefit to have one. Less gunk in the manifold. :banana:

I have wondered the same thing. My car just hit 95,000 miles. Would it be pointless this far into the cars life?

If you think that your car goes to 100K and then dies then yes it's pointless at this time. LOL

It's a great mod regardless the mileage.

I just installed mine and I can't wait to see what happens. It has only been a couple days and I haven't seen anything in it yet but I didn't expect too. I did however smell smell the residual. We will see what happens.

I too was a little weary of getting one. Does it really work, are they worth the money etc. So I made myself one. I bought a 1/2 air/water separator plumbed it all up, and put it inside a Monster Energy can. Looked sweet and my car ran on Monster! Well after having it on for a few weeks, I decided to check it. To my surprise it was full. It has a very small capacity so should of been checked sooner. I have since then bought a BT one. I haven't been able to test the BT one as the car is now in storage, but I am sure it will do the same. Before having a catch can I took my Air Hammer off to look inside the intake and there was a nice big puddle of oil. Now I see why they recommend plug changes every 30,000k. For me it was a no brainier, get the can and use it.

I think it was moreso a "has the damage already been done".

Does it really cause damage? or is it more to the lines of you just get alot of gunk in the intake???

Well I guess catch can joins the list of things to do!:banana:

That is my understanding now.

They keeps the oil from going into the combustion chamber. Oil burns at varying temperatures, and basically causes havoc with the combustion process. The Hemis are prone to getting knock from this... in this way it is considered a performance modification, as the computer isn't pulling timing to reduce the knock. More power!

OK how much more power are we talking about? is it like the CAI? Very little measurable power, or we talking like 5 HP difference?

All I really care about is extending engine life, but just out of curiosity, was wondering what the difference is?

These work on the 2012's too? 6.4l to be specific.
