About to install my oil catch can. Question

I've used catch cans a lot in the past, they help greatly. I personally hate any oil being sent back to the intake to "collect" because that's what it does. It burns some but I've popped off enough intake manifolds to know oil builds up.

My main question is Has anyone here done theirs regardless of their 4R's age or mileage and if so does Toyota has any issues with it? (Warranty issues or anything else)

Not real concerned but curious. They are easy to remove for trips to the dealer and then re-installed. Just looking for anyone who's been down this road already.


Thanks

Here's a pic or 2 for example

Not sure if you can see the oil build up.... I did a knock sensor job on this Yukon. Anyway a catch can would have prevent almost all the build up. There's one on that Yukon now

I've got one.. works great. Captures quite a bit of oil. I have to remember to drain it fairly often.

The motor moves a lot of oil mist via the PCV just like every other modern motor.

The only downside is remembering to drain it. Should not cause a problem with warranty.. but mine is out anyway.. so never think about it.

I run them on pretty much all of my motors. Just can't stand the thought of all that carbon buildup... Plus I feel it extends the life of the catalytic converters...
 
My 6.7 Cummins has the erg that fell off. Engines should not poop where they eat.

My Runner will have a catch can installed, it's pretty common and can't hurt a thing only help.

I'm same way. My 4R has 3000 miles. I've been slackn'. I'll get it on this week. Thanks man!

I totally agree. Maybe I'll do a write up. I think all cars should come with them and it just be part of the maintenance. It's simple.
 
Oil Catch Can

Looks like a good idea. What do you do with the oil you drain out? Is it clean enough to dump back into the engine? Currently my 2015 T4R TE does not burn oil, AFAIK. It does not loose oil between changes. So I have to wonder how much oil it would collect in an oil catch can? Anyone have any idea?

The oil tends to be combined with water... So I dump it out into my oil recycle. You could put it back into the crankcase and I have seen a few setups that do (some aviation motors do this).

Your truck does burn oil.. it's just a matter of how much. I've never seen the level on my dipstick move between oil changes either.

The catch can itself holds very little. You would have to dump it full many times to ever see a noticeable difference on the dipstick.

The oil it catches would have no way to make it back into the motor. It just normally goes into the intake and burns in the combustion process. So adding the catch has nothing to do with oil consumption.... unless you drained it back in and in that case it would reduce it.

Thanks @wfo9,
That doesn't sound like anything I'd want to dump back in the oil.

That is is my 4runner with the same 1grfe we all have. They all sound exactly like that.. It's exaggerated in the recording... It just looks and sounds a little different with the plastic engine cover pulled off.
 
Oil catch cans do nothing but help to keep the engine clean as long as you remember to dump them periodically. I installed one in my sister's 2013 SR5 and it ends up with 1/10 qt of oil between oil changes.

I had a BMW for a short time that would indeed recycle the blowby back into the crankcase.
 
Not sure you'll see too much benefit in regards to "cleaner" intake. The amount of oil people are finding is very small compared to most engines and I imagine much of the build-up is less oil and more carboning from leaving the valves open and some overlap built into the vehicle.

Just something to consider.

It's not like say a BMW or Prius engine where you can dump oil out of the intake manifold when you take it off.

It's not that much... Like someone else mentioned about 1-2/10ths of a quart per oil change...

To me.. (and it's just personal opinion) every bit of oil contamination you can keep out of your intake runners is worth it. What happens is that the oil accumulates.. then when you stomp on it and get some air moving the oil starts to flow and kills the effective octane and the motor can detonate. With DI motors, you can get a pretty nasty buildup that will actually block airflow... Another issue is the catalytic converter lifespan is negatively effected by the oil burning in the combustion process. These catch cans with simple media won't eliminate all of the issues, but they do help IMHO. The motors that I have put them on have been pretty much flawless. However, I did have one or two with bad cats... that I never put one on.... The oil is not just aerated by blowby. It also get circulated by simple crank windage.

Don't get me wrong, I don't think these are necessary for long engine life... I do however think they are worth the small effort it takes to install and maintain (If you are in to self maintenance...). It lands along the lines of the type of oil and how often you change it.... You will never really know for sure if it was worth the effort in a daily driver... When I was doing high boost race setups... the PCV setup was critical to long engine life. With a simple NA motor... who knows for sure. For a one time $100 investment for the life of the vehicle.... seems very worth it to me. Not for everyone though.

I'm not disagreeing with the idea. I just don't see a lot of these 1GR-FE's really having much of any liquid in the intakes. The oil mist at such low levels would hardly be an issue and you're still going to get more carbon build-up from partially burned fuel/air mixture (one of the reasons why DI's carbon up so badly is because of the insane amount of valve-overlap and EGR use).

I'm not saying to not to do it. I mean as long as you hook it up correctly I don't see it doing much harm. I just don't know if it will really do much for these engines in particular vs. say a Prius or BMW motor that literally has standing oil in the intakes.
 
Thread revival....
I'm putting in a CAI and I got to thinking about the PCV system. I searched for more info and ended up here among 15 other different tabs. While I'm glad to see the line that runs to the intake tube ahead of the throttle plate is the breather part of the PCV system, the recirculation line still introduces oil (and assorted crud) into the intake manifold from the driver's side.

I recall from my 60kmi visit to the dealer they suggested an intake manifold cleaning every 15kmi. Now this is a city dealer, where I had previously been visiting more rural dealers before and never heard of such stuff. After the cleaning I experienced a noticeable increase in performance and throttle response. If I can notice that on a simple before/after service on the same day, then it's something that should probably be done once in a while.

I'm was left thinking a catch can would help eliminate a lot of that. A few of those intake cleanings would cover the cost of the catch can. But before I drop $200-$400 on one, I've got a couple questions:

Anyone who has a catch can have trouble with it freezing in the winter?
Where are you geographically? What were the conditions?
What size can and how often do you have to drain it?
Do you remember if the can has baffles (seems important for performance and likely off-road)?
[MENTION=106176]wfo9[/MENTION] I assume you added one before the Magnuson, if not what did you do with the PCV recirc line?
