Oil catch can?

[JimmyVal]

 

It says 1 QT on their website which is 32 ounces but I think that's total can capacity or interior volume so you have to account for the filtration portion at the top. I'm not sure what the actual capacity of the safe reservoir area is but I've been draining mine every 750 miles or so in the winter to ensure it doesn't get overfilled. I really wish RX made their cans like some of the competition where you can see how full it is or at least unscrew the bottom to get an idea of how much storage capacity you actually have to gamble with.

Wow, they claim 32 ounces....

 

Man, I can't imagine it holding a quart. The container I used to drain the can was nearly the same size as the can itself and it was nearly full. In fact I thought it was going to completely fill the container and I shut the valve off on the can when it approached full.

I'd say at 10.5 ounces you were close to playing with fire there. I'd drain it more often based on what you got out. I wouldn't want mine to have more than 5-6 ounces or so in it just sitting there at any given time.

There's a cross section of an RX can from 2011. I assume it's the same size as our cans. You can see there's no way you get the full 32 ounces of storage capacity. You get 1/3-1/2 of that amount at best.

So is the RX can pretty much the one to get, I think you have all officially scared me into getting one lol?

et, I think you have all officially scared me into getting one lol?

 

I have the Elite Engineering catch can. The entire can unscrews from the top so you can see inside. Its less expensive than the RX but possibly hold less, the bottom part is about the size of a pop can. It works great and looks and feels very well built.

Yea... I've learned my lesson. I'll be taking your advice and draining it every 500 miles.

 

Thanks for the cross section picture. I often wondered what it looked like in there!

I'm sure your can will be effective. Living where you do I would keep an eye on it. For me it didn't take long to fill!

Yeah I'm getting about 5-6 ounces out every 750 miles here in Virginia. Mostly water. I'd expect that volume to drop significantly in the summer time when it's more likely to just be oil in the can.

How many miles ryan?

I have to check but it was about a month so maybe around 700-800

Drained mine for the first time after 1,235 miles. 37,935 total on the truck.

 

 

 

I don't have any way to measure the ounces so that's a .223 round for comparison. I saw my wife's Pyrex measuring cup sitting on the kitchen counter but I really didn't feel like being castrated today.

 

That stuff is nasty. Got some on my hand and it smells like kerosene.

After 7 days and 346 miles my can was about full. Measured about 5oz when I emptied it. The top was the oily residue but underneath was mostly the watery mix.

[patriot]

Don't let it get that full. You do NOT want to suck a bunch of that in your engine all at once. It would be bad.

Oh I agree with you there. But I've had the can Less than 2 weeks and didn't think it'd fill that fast. The out port was still an inch or so higher so I doubt I sucked in any. I can see why GM wouldn't install something like my version for the masses especially when people go 5000 miles or more between oil changes. The design would have to be a much larger reservoir.

I am new newer this forum. Been reading several of these catch can topics. I just had a few questions. Looking at mjj's picture up above in post #604, I had a question. Not knowing how the intake is plumbed, I noticed that both valve covers have a hose that run to the air intake "wing" apparatus? Is that air that is being pulled out of motor to be reburned, or pushed into the motor?

 

I was going to attach an edited picture, but have yet to figure that out.

Any update on the Saikou dual cans? IE pricing, availability, etc?

I put mine on Tuesday. Drained about an ounce out of it today after 100 miles. Also cleaned the throttle body. Happy that this stuff is not getting back into the engine. I went with the rx can. Have a trip to Florida next week. I'm interested to see how much I drain out of it then.
