Can we argue about Catch Cans again?

The other thing to remember is that a catch can adds a maintenance item with a service interval that varies with conditions. If you forget to empty it, and it doesn't have a float valve of some sort and that gooey liquid gets sucked into your engine...

 

That guy is so obnoxious, if he told me to put gasoline in my truck, I'd use diesel, just to spite him. Can't stand his videos.

 

You would have to show me just ONE example of where carbon deposits on a tacoma FKS engine created a driveability issue (and created a maintenance/warranty issue). There is no reason for a catch can on a DI FKS Tacoma. It will not extend the life of the engine in any capacity. It is just oil vapor going back to be burned.

 

I don’t think they are necessary. Folks will pull out that can and show you how nasty and brown this crap is inside of it but isn’t every fluid “nasty” that comes out of your rig? I personally don’t mind that my motor is doing what it’s designed to do. Burning off that crap has been fine for this long, why re invent the wheel? I’m very particular on my maintenance, oil every 5k and transmission fluid every 30k. I wouldn’t dare put one of thoes POS cans on my new truck. Happy Friday folks

 

holy shit...I mean, you got me, I am falling for the troll. What a ridiculous video by a guy that has been sniffing brake cleaner for far too long. It's a great expose` on the history of cars and engine technology I guess, if you can get over his "stuck a fork in the outlet to prove electricity is a government conspiracy" look and sound. This was probably useful info in the 80s/90s... hard pass for me. At this rate, the gas engine will be obsolete before a 3rd gen owner needs to worry about this. We have enough paranoia of literally everything else going on with the trucks. Lets just go back to arguing if the TRD Pro is a good deal if I buy it on a Tuesday or something equally inane.

Happy Friday everyone, now I am all wound up and going to have to go yell at the squirrels to get off my lawn just to calm down....

 

All of our diffs will explode by then anyways. And our trucks will catch COVID-19 and need new air filters to breathe again. These are the REAL issues we should be worried about!

 

Being really new to 3rd gen Taco's, I had a huge smile on my face to see that Toyota went with both MPI and GDI which my old ride ('13 Sonata GDI) did not have. I will be putting it back on the Taco shortly since under load it runs off of GDI which is also where you'll get the PCV opening up. In the winter time, I would empty mine monthly and it did catch quite a bit of delicious looking water vapor and vaporized oil. Summer-time is not as much concern (mainly because it doesn't have time to condense). Keep in mind, "back in the day" the crankcase used to vent directly to the atmosphere (along with EVAP) until certain regulations came into place.

So do even the cheap ones work? Yes-to some extent.
Is it worth it? Don't know without actually taking a before and after.
Is GDI intake valve caking a concern? Absolutely, but again FKS does it right here with port injection.
Will your engine outlast the frame without it? Probably.

So why am I putting one on mine? Peace of mind mostly and again, coming from a filthy GDI engine even 20% less deposits matters but that also comes with regular maintenance (not 10k oil changes-not trying to pick a fight here) and using a quality synthetic oil.

 

Regular maintenance with any approved oil with be fine and comparing the 2 engines is apples to oranges. You can run Supertech or Amsoil for 200k miles. You’re engine isn’t really going to care.

 

The argument here is that the oil vapor reduces the overall fuel octane potential being injected into the combustion chamber and so it is better that you run one in order to keep your air charge clean.

Just like you I do not run a catch can on my boosted 2nd gen, nor did I run a CC on my overbuilt LSx engine... I just simply never saw a need for it. A properly functioning PCV system should not require servicing outside of the normal maintenance it's designed for. Drive it like you stole it, maintain it when necessary, and it'll last you the service time which you need it to. If catch cans were so important than they would have had them installed in the vehicle from the factory, but the simple fact of the matter is that most vehicles when maintained properly make it to 3-400K without issue. Hell you'll end up replacing head gaskets in that time before you blow it due to a PCV issue.

There is a way to turn the PCV into a NCV for more power, but it's expensive and really should be used for race purposes only.

Just the way I see things.

 

...so you're saying there's a chance

 

That is not the primary purpose of installing a OCC. Unless you are racing cars, 'fuel octane potential' is not applicable either.

 

Not needed with this engine. The "evidence" that they needed is only self verifying. Or put another way, saying you need a catch can because they actually do catch oil is akin to claiming that you need a light bar because it lights up when you turn it on. Doing the task it is designed to do doesn't speak at all to it's necessity.

 

I'm saying that is what some guy who would want to debate with you or sell you one would say.

I don't give a damn about the fuel octane potential. OE designs for crankcase ventilation are suffice for me.

 

Everyone hates Scotty on here. Is it weird I like his videos. lol

 

I want to address the comment about "Engineers" that I see time and time again. You have to remember, we don't really know the goal of the Engineers, which includes me. For example, it's very possible that Engineers decide that the benefit and complexity of a Catch Can, for the normal driver, is not worth including it.

Here is just one example. Generally speaking, do you believe automatic transmissions should have a dipstick and a fluid-replacement schedule? If you do, then why don't Engineers include it anymore? Because for the normal driver, it is not worth it and probably the Marketing department probably has something to say too.

So the comment "Well, if it was so great Engineers would have added it" and "Well, Engineers know better than you" I say that's a false argument. And besides, how many vehicles have had mistakes in the Engineering and choices made? Most models from manufacturers have issues, that's why they have recalls. Ford Pinto? Tacoma Fuel Pump? The list goes on and on.

 

Sorry, but I can't take advice from the Joe Exotic of automotive maintenance.

 

Hey, Joe Exoctic knows a thing or two about tigers is all I'm sayin....


And yeah to everyone else, thanks for you're input. If I was more mechanically oriented, I would be installing one just to reduce any gunk in my engine, even by a little bit. I agree that engineers don't always do what is best for the truck, we do live in a throw-away society after all. I want my 3rd gen to be one of those sick classic trucks you see riding around town one day in the future.

 

Catch cans seem a little too "extra" to me. Unnecessary busy work. Multiple vehicles over 200,000 miles (Over 300,000 on my current Tacoma) & no catch cans in sight. Just change your fluids regularly & you're good to go.

 

I agree with you all; Scotty is a fucking clown.

OA

 

Can I fit 35s without trimming if I install a catch can?
