Removed my S&B cold air intake!

Yep. There's numerous parts I too would definitely disagree with you about that on (shock absorbers, just to name one).

 

Dust is just a term for tiny shit. I know that when I was a kid an my house burnt down the firefighters said dust doesn’t burn. But really everything burns. Especially when it is dust sized. It may leave some sort of carbon, or charcoal residue. Which either burns more or dries to a nice shellac.

 

to say that the o2 sensor was clogged by dust that passed through an oiled filter is pretty far fetched. you've got a better chance of screwing up a MAF or something than that happening. but its ok we can see you're on a high horse and can't be told you're wrong....

btw 300k miles + with airraid, k & n and air hog and zero filter related issues on any of my vehicles. Actually zero issues of any sort on any of my vehicles. but I'm sure my porsche will just straight blow up sitting at a stop light because i've got oiled filters in it.

 

No, but the factory paper filter works fine with that setup.

 

What I found in the O2s was grayish and gritty, it wasn't carbon or charcoal. I could maybe see the dust melting though (like how rock turns to molten lava)... After all, dust (the silicon kind kicked up from the ground) is just microscopic tiny rocks.

Ok, you're right... All the dust that went through the engine (molten or not) simply vanished before reaching the O2 sensor. All the hard gritty material I found clogging up the sensor was just a figment of my imagination.
You take your Porsche offroad a lot?

 

Right, lets blind people on the road for 29.99 using after market junk that has less regulations to meet

 

so what do you guys think about this option. Some say it’s better than the catch can.

so yeah it is just your imagination. learn how things work.
yes, my porsche does see off road action.
quit living in an imaginary world forcing your incorrect view of how things work on people, its misinformation and its nonsense.

 

Dang, that's stealing almost an exact idea of mine (ok, I hadn't ever shared it, so complete coincidence lol). Mine was to put the fitting on the oil filler neck, but wasn't sure if it would simply switch the issue from ingesting oil on uphill climbs to ingesting it on downhill climbs (their page says: "There are also oil drains located near the front of the cylinder head, allowing for sufficient oil drainage." so maybe the idea will work).

That setup (by itself) wouldn't provide the other benefit that is said of catch cans, which is to extract the oil mist that flows through the PCV that dirties up the intake & valves with oil deposits. My idea was to also have a can on the line as well (the benefit being so I wouldn't have to remember to empty the can after each offroad trip, instead I could do it at each oil change).
That said, I've never experienced any running issues from plain oil mist in the PCV on any of my vehicles, just the dust that had affected the MAF and O2 sensors and caking up in the intake when I had the K&N. So for me, the peace of mind is mostly in knowing my engine is safe while on a steep climb.

 

I know 2x 3rd gens with high milage and i am sure you do too. One is the guy who has video with 400k 2018 model and other is a guy who travels the world without after market oily air intake filters and PCV upgrades and all that. He instead has fridge and kitchen in the bed. Front ARB aluminum bumper to keep truck safe. That's what I call good and reasonable use of after market parts.

So, yes, the OEM is better than that. If it wasn't , those 2 gentlemen who use the 3rd gen taco the WAY IT SHOULD BE used have done that. Pretty sure most people who live in rural areas and use trucks for truck things don't waste money on stuff like that. Its not Ford or GM or a race car.

Now this is obv just my opinion, its a free world and its your money so do as u like. But as far as me being asked about it, OEM will always be better than after market unless its like upgrades i mentioned which do not come as OEM.

Besides, that looks like aluminum / steel and putting that on plastic is pretty bad idea. What if it gets stuck and you break it off, then what? also i dont think V6 tacos burn oil if they are maintained

 

But what I’m thinking about is, wouldn’t this introduce containment into your oil? Where is a catch can would catch at least 95% of it according to some? The stuff I saw inside the intake assembly. I definitely would not want in my oil. Or am I overthinking this? I do like the idea of using both.

 

So here is a video On it. I don’t know if capping off the PCV valve is a good idea…tell me what you think

Hmm... yeah, easy enough to just swap in the oem paper filter in place of the oiled k&n then, if it fits in the cai airbox.

 

The stuff you saw inside your intake assembly (I assume the filth allowed in by your S&B) is an entire separate thing from what a catch can addresses. There are no "contaminants" that harm the hard parts of your engine traveling through the PCV system (this aside from the oil-ingestion issue while on an incline). All it is is oil mist and some condensate that over time is said to lead to buildup of deposits within the intake and on the valves.
The stuff you see collected in the can is often pretty groady-looking, but it's just an oil & water emulsion. I'd bet if you heated it up enough to evaporate the water, it would return to looking like normal clean (but used) engine oil).

As for "capping off" the PCV... I haven't been inside a 2GR-FKS myself, but I wouldn't think there is a walled-off section inside the valve cover between where the factory PCV fitting is, and the oil filler neck. All that is being done is relocating where the crankcase vapors exit from. As long as the head has sufficient oil drainage at the front of the head for when you're pointed downhill (as their web page says it does), then I don't see that this can't solve the issue (I'm surprised I haven't seen this kit mentioned on here before, yay or nay... This has always been a concern of mine too when I'm out on the trails).

 

The paper filter fits. If you wanted you could order just the top piece of the air box with the TRD logo and the intake flow accelerator. The trd intake doesn't really do much for performance, but it does increase sound.

 

I just swapped in the oem paper air filter into the trd cold air intake, fits like a glove. never knew the oiled k&n wasn't as efficient at removing the smaller particles.

 

OK so then how does the crank case ventilate if it’s capped off like this video shows? I understand it solves the oil going into the intake on inclines but what about the purpose of the PVC valve?

 

Ah, I see what you're saying now, it looks like the actual valve itself is still left in the valve cover.
I thought that whatever was spliced into the middle of the hose in the video might've been the valve (or a replacement valve), so now I'm wondering what that was on the hose (I don't recall the video mentioned anything about it)... If it was a replacement valve, then there should be no issue. I'd suggest give RM a call and ask them about it.

Otherwise, if you can devise a way to remount the existing valve on the oil cap (or figure a way to splice it inline with the hose), then plug the hole on the valve cover, I think would alleviate any concern here as well.


This is something that needs more investigation for sure.

 

My 2023 came with the fancy red TRD oiled filter. I drove the truck home, then the next day on the way home from work I stopped at the dealer and bought a paper one. Made me happier.
