About to install my oil catch can. Question

Surprised catch are being put on these vehicles...based off my experience they did nothing whatsoever to reduce carbon build up. Coming from a GTI which are notorious for early carbon build up, it was proven the catch can did little to nothing to reduce build up. Same results for both mine 2013 TFSI and my buddies 09 TFSI. What would be so different on the 4runner especially with no forced induction?

Carbon build-up can just be part of fueling and have nothing to do with the oil from the PCV. The main purpose of the oil catch can is to improve effective octane and keep the intake clean. It can't possibly catch it all...

From my experience.. the combustion chamber is never a big problem (on port injected motors) from the PCV. The fuel washes it right out and keeps it nice and clean. The problem is the intake and runners. They gum up. Also, once you get on the gas after lots of build up. The oil pushes down and there goes your effective octane and it detonates. Knock sensors pickup it up and keep the motor together, but power goes to crap.

These cans can't prevent all the oil. But every bit helps IMHO.

On direct injection motors. they do have problems with buildup from the PCV and it can be very expensive to clean up.

Here are some pictures of my 5th gen intake runners when I took my manifold off at about 70k (before I cleaned it). The truck had 45k on it when I got it and I put the catch can on at about 55k. It was pretty nasty and it appeared that most of the buildup was very old.

The ports after the injector were not bad and the chambers and pistons were nice and clean. But the intake runners were nasty. It cleaned up easy, but the consistency was like a partially dried glue.

Install complete. Mounted the can on the driver side fender using one of the unused factory threaded holes. 3/8 vacuum hose from NAPA since the included hose was a joke and not vacuum hose. Put some loom on the hose to give it a factory look and will put clamps on the hose at the canister tomorrow. Forgot my clamp kit at home but really don't even need them, hoses fit snug.

Finally getting around to installing mine. What size bolt/thread did you need to use for the factory holes?
 
Well I got mine mostly installed... what a PITA. Don't buy that McNally kit!
The Idiot Thread - Oil Catch Can Install

Took me about 30 minutes and was one of the easiest mods on the planet. Would take half that next time because I don't have to figure out where I want to mount the can. Looks like you made it more difficult that it needed to be lol. Why mount it on the passenger side when the connections are made on the driver side?

Because like a typical idiot I completely didn't consider mounting the bracket horizontally instead of vertically. Hence I thought I'd have to fabricate my own bracket to install there. I didn't have the materials to do that. I also want to use the space on driver's side for electrical busses. I didn't realize the can was so big before purchasing, I'd get a smaller and less expensive can next time. I was actually extremely disappointed with this kit for the cost.

Did my normal 5000 mile oil change today and took a look inside the catch can. Not really sure how many miles are on it after install, maybe 2000 or so. Certainly doing it's job that's for sure. Majority of what was in there was water, likely condensation. Slight bit of oil, smelled like oil, glad to have kept this out of my engine.

Which catch can did you go with?
 
Good post.

For those wanting to save a couple dollars, don't go with a can with the clear hose on the side. They're all over eBay and Amazon. They alright for a couple years, but the plastic gets very brittle and will cause the occasional CEL.

I don't see the benefit in spending hundreds of dollars for an aluminum reservoir, when there are cheaper alternatives out there.

To bad we don’t have plug and play ones available like the mustangs do.

Factory uses a piece of 3/8 hose between the valve cover and intake manifold. This uses 3/8 vacuum line in a loop through the can. How much more plug and play can you get? There's even already a threaded hole on the fender to bolt the can to!

Thank you for posting this!
Just curious how the top cover of that can looks like from inside... is there like a mesh (or something similar) that actually "catches" the oil?

The inlet side has a screen that helps dissipate the mist coming in. The screen is about the side of bottle cap and can be unscrewed. Some guys put a little steel wool or something like that in there to help slow down the air but I personally don't like that idea. If the steel wool was to come apart, it COULD get sucked back into the intake and that's not something you want.

Guess I should of popped the hood a looked. On my mustangs ford uses a quick disconnect fitting.

It's a Ford, enough said lol. There are aftermarkets with quick connects also, read the multiple catch can threads, they suck and people hate them. Sometimes less is more!
 
I looked into a homemade can. Not worth the time and effort. Not to mention they usually cost more than just buying one like the $25 ebay can.
 
DO what you want.. But I've personally tested these cans including the old school inline air compressor filter approach (they don't work well at all).

Buy a decent can or don't bother. The mesh media designs with a diverter makes a huge difference. Years of testing have been done to verify the differences.... it clearly catches more oil and is based on a design used in aircraft engines for 40+ years.
