Has anyone installed a oil catch can in a 2019 Tacoma.

Has nothing to do with oil consumption, if your engine is consuming too much oil its needs to be rebuilt. They are not as necessary on older engines. On DI engines they can help. Our taco has a dual system so its less clear. We have all debated if they are needed and the general consensus is your taco will still run without one, but will it run better with one? It's one of those things you have to decide for yourself. There is a ton of information out there. A lot of manufactures use them including Toyota, but that does not mean one is required on our vehicle.

You have to decide for yourself if you want one, there is no proof either way on our engines if it is beneficial or not.

 

Its not the moisture, its the oil in the vapour.

 

Just thinking about this and I would have to say I don't know. If anything it would have to be a science experiment. If you put one on and the smoking stops then you know it works. As the separator draws from the drivers side top of the valve cover you would have to be on pretty extreme angles to get an over flow of oil up there. Not sure on that one.

 

Then you're trying too hard with this increasingly monotonous thread..

 

How about this.

There's no proof that this is beneficial for our engines thus far. If you show me two identical tacomas with identical mileage, driven under identical situations and one with and one without a catch can over a period of 300k miles then we can have a discussion. Other that, let people spend their money on catchcans but also stop trying to preach to others about benefits when there's zero proof that they help with longevity on our motors.

 

It's because people demand absolute written proof for our engine and there is none, and there will never be any because that would mean Toyota was wrong. These things sure can help in the early Lexus where carbon build up was a problem and Toyota probably knew that, but instead of adding a separator, Lexus extended the warranty, cleaned your engine, did not fix the faulty design and when it happens after the warranty period you get a big bill, that was the answer.

What we know is they are used by other manufacturers, race cars use them and they filter out oil from entering the combustion chamber. I hope we can all agree that oil in the combustion chamber is not good, it dilutes the air fuel mixture and can cause build up.

Our engine is relatively new speaking and I think its an excellent design. I am grateful Toyota employed the duel injection system.

The purpose of this whole thread is not that our if trucks need one, that is not it. Our trucks will not explode if you don't put one on.

Will a oil separate help with longevity??? I think so. The purpose is can it help improve an already good design? I think so as oil in the intake is no good. That's the whole purpose. If you are happy with the status quo don't get one.

Just because it appears Toyota didn't put one on this engine does not mean adding one can't help. I take all the facts I know and draw an inference and make a decision. Everyone else is free to do so as well. This is one of those technologies you have to decide for yourself.

 

I have not preached to anyone? This forum was about a discussion about a mod. That's all. People are free to do what they want. You are not a believer so don't get one.

Edit - Also asking to compare two trucks driven identically for 300K miles is impossible. So what you are asking is not reasonable.

 

I will say if I get my hands on a supercharger for this truck I would deem it necessary to run an oil catch can.

 

Yes, on boosted engines it is good at keeping the cooler bricks clean amongst other things.

 

Ya but we can only dream of such a day at this point

 

Sure, that's why I said people shouldn't give a damn whether people have one or not. But there's zero proof that this works on our engines yet.

 

Some people like to try to prevent things from happening and don't like to wait. I hate to use this example but there was a time when smoking was cool and no one believed it caused cancer. It took a while but society came around. That is extreme and I don't want to offend anyone. All I am saying is some people will never come around unless your engine explodes. Which it won't.

What would be very interesting is if someone has a gas analyzer and can hook it up to the truck and analyze the particulates coming out (that you can't see) and do the test back to back with oil separator on and oil separator off. I would love to see that. If I had a gas analyzer I would do that.

edit - spelling

 

You would also need a dyno. You definitely would never see it by just revving as there would be no blow by. You would need it under load and even then by the time it reaches the end of the exhaust you shouldn’t see anything

 

You could be right. Putting it under load is a good idea.

 

I did find this on a Honda forum, but don't know if it would apply to our tacos.

I keep reading this thread and asking myself, WHY? The stuff that this catch can is catching is only a small fraction of the oil and moisture that every engine burns on a given day. Ring blow-by works both ways. Combustion byproducts down and oil up. The samples I have seen in this thread of stuff caught are nothing! Now if you were catching litres of stuff then maybe this would be worth the time and effort. Race cars use these to catch excessive oil blow by to keep it off the track and from low tension rings and even then they only do it if they have too... weight is more important. As for emissions, the EPA sets those standards not the manufacture. These engines are designed to recover that tiny amount of byproduct and burn it to meet EPA standards. This is something that is not necessary on our engines. If you want to waste your time on this have at it.

 

Hello, I am brand new to this forum as well as this thread but wouldn't this void your warranty? And also wouldn't this not be allowed in emission states such as California? Just a thought.

 

The moisture is what gives it that ugly chocolate milk color when folks show their catch cans. Either way, it's all just fine to get burned away in the combustion chamber.

 

If I understand correctly, you aren't supposed to modify your emissions systems (which this would be)..... In reality, you are just catching this stuff as a solid and dumping it out before it gets burned away, which probably is an improvement as far as what you are sticking in the air.

 

I understand you, but wouldn't this also void your warranty unless you removed it when you took your vehicle in for service? I asked because I have 10yr/100K mile extended warranty on my taco
