Get a catch can before any mods.

[HiHoeSilver]

Just finished installing mine. The can from catchcan.com is not worth the money! I was highly disappointed when i opened it up and saw how close the dirty and clean ports were from each other. The filter media was also a joke...

Anyways, i modified it a bit with a 1/2 copper pipe and jb weld. BEWARE that copper and steel are incompatible! One or the other will start to rust. This is temporary until i can source some steel pipe. Probably from home depot.

I ended up with extra fuel line. Come smog time ill attach the piece of pcv pipe i cut off back

That's a nice mod. Good idea.

Why would you have to revert back at smog check time? It's a closed system, doesn't vent to atmosphere.

Because California. Nothing can be modified unless it's carb approved.

I added one stainless scrub pad to mine as-is and never gave it a second thought. I like this idea. I consistently catch 3 ounces per 5K miles, so I'll leave space for that amount in the reservoir and fill the rest with more filter media (scrub pads).

Here is an article about a Moroso catch can

22mpg?! How the hell did you manage that?

hybird could do 40MPG pure highway... amusing flat land like Florida

I gotten as high as 39.9mpg here in the city it's as flat as florida around town 36MPG is typical in the city. assuming it's more then a few mile drive ( going to the store cost more because of having to warm the engine and that waste a lot of gas fast) so if i'm going to the next city over i can get 36 to 39MPG) not too bad for a hippo suv(as i can keep it in V4 mode for extended periods using the High octane fuel)

Ok I just took the plunge on one of these from Amazon. See how it goes...

I am curious to see how well that can works... it should be easy to tell with the clear hose... keep us posted, with pics.

Anyone else find humor in the fact they thought it was necessary to put “OIL CATCH CAN” on the cap?

It's red too, so it will definitely add extra horsepower!

Yep plus 10 hp.

Sorry for letting my engineering mind kick in and likely over analyzing the situation.

Is there any guidance folks can give for maximum length of hose between valve cover and catch can? Should a person worry about the hoses being long enough that the suspended vapors slow down and settle in the hose before reaching the catch can? If so, I would think you would want to avoid a saddle point where that settles out liquid can accumulate and cause a blockage over time, causing someone to 1) minimize the length of hose and 2) route the hose so everything either drains back to the valve cover or into the catch can. Am I overthinking this?

 

[HiHoeSilver]

Am I overthinking this?

Yup.

 

[wjburken]

Yup

Thanks for the sanity check.

Lol. As long as it's in the engine bay and you're not coiling/ kinking/ crushing the hose, you'll be good.

Any pics of the insides? Or link to it on Amazon if there are pics there?
