Any interest in catch can kits?

[telum01]

Hey all, I recently put together a custom-spec catch can kit for my other car and it has been extremely popular. I'm about to do one for my 4Runner and was wondering if anyone else would be interested. If I can get enough people on board, I'll order a batch of them.

Here's the deal:
I'm designing the kit for V6 4th gen 4Runners, based on my '06. If anyone wants one for a V8, I'll need to check and see if the same setup will work but I'm not designing one for the V8 independently.
Everything needed for installation is included - catch can, mounting bracket, nuts, bolts, hoses, zip ties.
100% reversible, it uses existing bolt holes and requires no modification whatsoever to your vehicle.
One hose is removed, and can be bagged and tagged for reuse if you decide to remove the kit.
Extremely high quality components (I have them in my Aston Martin and have put it through thousands of miles and several track days).
Two options for catch can finish: brushed aluminum or wrinkle black.

Cost:
Depends on a few things, but ballpark is $250-300 shipped (48 States), everything included.

Picture below for reference, the catch can is in the bottom of the pic next to the power steering fluid reservoir. It's extra shiny because it's brand new and the rest of the engine bay hasn't been cleaned lately lol.

We've got a few active forum members local to me that are welcome to hit me up and check it out themselves as well.

Could you explain the pros and cons of this please?

Is this a standard catch can that's supposed to collect oil from the PCV system before it gets back into the intake? I'm not sure what benefit it would provide to a 4Runner. FWIW, I installed one of these on my E90 335i; these cars are notorious for carbon build-up on the intake valves due to their use of direct fuel injection. Our trucks don't have DFI so this isn't an issue. Furthermore, after running the catch can in my 335i for a few months it was bone dry.

Copy/Paste explanation I wrote for the Aston kits, edited to remove details specific to that car. BTW, I shipped a few to Canada - it's 30 USD more shipped compared to the US prices.

The purpose of an oil catch can is to prevent oil vapor from contaminating the air/fuel mixture that goes into your engine. The catch can I'm using is internally baffled, which helps force the oil from the vapor to collect in the can rather than continuing through to the engine. The vast majority of the catch cans you'll see for sale are not internally baffled, which is why they cost half as much as the one I'm using.

Oil vapor is one of the ways a car "consumes" or "eats" oil. (The other primary way is oil blow-by getting past piston rings and directly into the combustion chamber.) You can easily insert a recirculation line to reintroduce the collected oil to the oil sump. However, this oil can contain contaminants. It's worthwhile to inspect the oil when you empty the catch can to see if there's anything mixed into it (coolant in particular). As with any vehicle, checking oil levels regularly and topping off when needed is recommended. Most people know that some cars "eat" oil, but they don't know why. The catch can collects oil so you can actually see the oil that would be consumed. I keep extra oil on hand and top off with fresh oil, discarding what I drain from the catch can.

Oil consumption is fairly common with just about every car. Some do it more than others. Before getting started on my original kit, I rigged up a makeshift one from Home Depot supplies on my 4Runner. It quickly started collecting oil and showing its value.

As for whether or not you need one... no, you don't need one. Your car will run without it, just as it has always run. However, the catch can does help. Removing the oil from your air/fuel mixture will give you a cleaner burn, improving your engine efficiency, emissions, and so on. Long-term, the cleaner burn will help prolong the life of your catalytic converters and O2 sensors.

Take all of this with a grain of salt, as those effects may not even be noticeable to you. The way I look at it, this is a fully-reversible kit and it does in fact prevent oil from getting into your intake manifold.

Hope that helps!

And here's a pic of what it collects, which would otherwise end up in your intake manifold:

I've been running a Home Depot Special catch can on my 4Runner for a while and it is definitely collecting oil.

DFI engines are much worse for carbon buildup - especially with Audi. But even 4Runners have oil vapors getting sucked into the engines. The pic of collected oil in my post above was taken from my 4Runner.

Hmm.. Seems pretty simple. So a couple houses and a container? The container will be under pressure I'm assuming.

Catch can (container), bracket, hoses, nuts, bolts, zipties - everything needed for installation. Nothing gets permanently altered on your T4R, just pull a hose and store it for later if you return to stock (although I'd replace it, they're getting old and brittle!).

The catch can and mounting bracket are made to custom spec and are very high quality, made of stainless steel and aluminum. The catch can will not see high pressures unless you've gone forced induction, and even then it will handle them just fine.

Thanks for posting the link!

Btw, I'm right down 28 from you

I was wondering haha. You ever go to Friday night live in old town herndon? Saw an Aston Martin there that looked like yours a couple months back.

 

[telum01]

Did it have a Georgia plate on the back? If so, that's me! I've only been in Herndon on a Friday night a couple times. There's a spot I like there called The Icehouse.

 

[HokieRunner]

Can't really remember to be honest. But I'm at O'Sullivan's and Icehouse all the time. The bartender at the Icehouse makes a killer 'old fashioned'. We'll have to have a mini meet there sometime haha.

on a side note -Sorry for the off topic banter....

 

[curtis325]

Interesting idea. Anyone done it on a V8?

Yeah people have done it on tons of cars, including various 4Runners. I'm just offering a clean, comprehensive, high-end kit since I'm having it made for my 4Runner already.

If enough people want a V8 kit, I'll set something up but you'll have to convince a local V8 to contribute some time to design off his rig.

4Runners aren't DFI. They get a constant stream of detergent-infused gasoline spraying on the back of the intake valves so there's no carbon buildup. Sure, oil vapors are getting burned but by and large people on this forum are driving their trucks for well over 100K miles and I haven't witnessed anyone complaining about a carbon buildup problem affecting the way they run.

I never said 4Runners have DFI??
