    I will, I'll do a follow up video. I was probably the first person to have a catch can on the 3rd gen. If you search 1st catch can on 3rd gen or something like that (I can't remember exactly) I posted a thread a few years back. I installed the catch can, but not the best install. I wanted to make it like factory so I re-did it and did a video of it. I can say I empty it regularly and there is stuff in it. Also my exhaust pipe was silver inside for the longest time (when you look inside)

    That's awesome, thanks soo much!!!!! If you have a channel and you want me to subscribe put a comment in any video and I'll click on your name and subscribe to you as well. Thanks again!!!!

    the Amount of blow by in a NA engine is so minimal especially when it’s not a high revving motor. The fact that Toyota even put port injection on this motor is just a testament to their commitment to make reliable engines meant to last hundreds of thousands of miles

    It's such a tiny amount it won't hurt anything. PCV systems have been on cars for decades and this hasn't been an issue. The stuff that comes out of the crankcase is vapors and passes right back into the engine (in tiny amounts) as vapors. Your catch can is cooling them back off and turning them into liquids (mostly water).

    A can's not going to hurt anything but it doesn't really do anything either. Not only do we have PI but new oils and engine control strategies have eliminated this issue on even DI only engines. If this were an issue on these engines you'd have seen examples of it. But people spend a lot more on other mods so have at it if it makes you feel better.

    Yes, I was going to say....Every time im sitting in a drive through or whatever...I can physically hear the engine change as it goes into its cleaning cycle. As soon as you hit the throttle, the sound goes away. With it doing this every time it idles, I think its fine. They pay engineers loads of money to figure this stuff out. lol.

    If catch cans were such an important part to longevity, such a cheap item would have been installed from the factory.

    You are right on many fronts. A little bit about me as I feel I have to qualify myself. I am a licenced mechanic (not for a Toyota dealer) so I have pulled many engines apart over the years and have seen the worst hack jobs to some of the best mods. That being said...…. I worked on a GM intake a few months ago (for a friend) and there was oil everywhere in the upper plastic intake, his intake was leaking coolant and its a rubber seal so we figured quick fix? The oil had degraded the part so that the intake manifold material underneath that holds the gasket was soft (getting disintegrated by the oil) so he needed to get a new plastic intake. Now I don't want to fear monger anyone and I don't want to sound like I'm preaching but if there was no oil in his intake track this would not have happened. So its not just the carbon build up, its the oil that gets everywhere in there and causes other problems. I wish that I would have filmed this one, I truly regret that!!!!!!

    Now I know someone will say its a GM hahaha, I get it. You might be right that if this was an issues we should have seen something, but these engines have only been out since 2016, so not long and most are on warranty. All manufacturers are going to do their best to ensure their engines make it through the warranty period. I love my taco and want it to last many more years.

    BMW and Audi engineers that know best thought the same (that no oil separation was necessary), or maybe they were directed otherwise when their DI engines came out and just google "walnut blasting audi". Keep in mind this extreme happens after the warranty period in most cases after a number of years.

    They are on almost all motorcycles, at least the high performance ones. Chevrolet also has one installed on the Camaro. Dodge build them into the valve covers of the hellcat. VW/Audi now builds a type of one into their TSFI engines. I did film that one I took apart due to misfiring and carbon build up (not posted yet). There may be others. Also most race cars have them. I know out Taco is not a race car, but if you tow you are loading the engine.

    Stuff that my wife thinks I don't need.
    I've never really formed an opinion of catch cans. I will, however share my experience with them. Just because.... Oh, and if you listen to anything that Scotty Kilmer says....

    Anyhoot. I had a 2011 GTI. It's a turbocharged 4 cylinder. My wife has a 2008 Passat. It has a similar motor. These two motors are notorious for two things: PCV systems failing, and making a mess of valves because of the direct injection. I cleaned the valves on both of these cars. One was heavily modified as far as a bigger turbo, tuning, etc (GTI), and the other was not. The GTI was done at 75,000 and had been running a catch can for most of that. The valves were almost as dirty as the Passat's were at around 111,000 miles. I traded in the GTI shortly after this. The Passat is still going at 190k miles. Oh. The reason I cleaned the valves on the Passat was because it wasn't running so good. It was drivable and all, there was just a loss of power.

    One thing you have to be careful of with a catch can is that the lines don't freeze. Ask me how I know this.

    I had the opportunity to compare this to a NA car (Mustang), but someone totaled it about a year and a half after I got it.

    Just some experiences to add to the ol' databank.

    It was a 3800 in a Chevy Impala. The ones with the black plastic intake on top. They also leak coolant from the o-ring fittings in the intake.

    Hmm. I know the old vortec 5.7s had a similar issue, but it was due to EGR.

    I don't have an opinion either way, but this is right from the 3rd Gen Tacoma engine manual.

    In low to medium engine load ranges, both direct type and port type fuel injections are used together or
    one of them is used to create homogeneous mixed air, thus contributing to stable combustions. With this,
    the system achieves low fuel consumption and low emissions. In addition, in high engine load ranges, only
    the direct type fuel injection is used to cool down the intake air with the chilling effect of vapors in the
    fuel which is injected into the cylinder, improving charging efficiency and anti-knock properties.

    Immediately after the engine is started in cold state, the fuel injector assembly on the port side is selected
    for the injection aiming at homogenizing the mixture in the combustion chamber. Next, the fuel injector
    assembly on the cylinder injection side performs fuel injection during the compression process in order
    to stratify the mixture layers around the spark plug. This formation not only enables a substantial
    retardation of ignition timing but also raises the exhaust gas temperature, which facilitates the warm-up
    of the catalyst following a cold start.



    Looks like port injection is actually used a lot of this time, and it runs primarily on DI MOSTLY in high engine load ranges. The rest of the time the engine does what it wants haha.

    So if I'm reading this correctly, there was no perceived benefit in you experience?

    These engines have been out longer that 2016 in Lexus and other Toyota vehicles.

    Good information. I actually wished the port would be used on high loads as that's when blow by is the most. GM's ZR1 has a duel system and the port is activated under load.

    Ya I didn’t want to burst any bubbles but the manufacturers already figured out the problem. It wa
    as someone who works on bmw engines they fixed carbon issues with their second generation of direct injection engines back in 2011

    Stuff that my wife thinks I don't need.
    That's what I experienced at least as far as when I went to clean the valves on both cars. I'm still up in the air about whether the catch can has any benefit. Logically, there was some nasty crap I emptied out of the catch can. But I also know that junk gets "recycled" in the engine and the water burns off. Is that bad? I have no idea. A cylinder head *can* collect moisture by just sitting.

    The Tacoma is designed to splash a little gas on the valves to get the gunk to burn off, so that SHOULD make carbon build-up a non-issue.

    Personally, I would never put one on this truck simply because I don't want to remember to have to empty it. It's one less maintenance item I have to worry about. I already have two maintenance intensive vehicles to worry about. I don't need another one.

    Our Atkinson engine has been out prior to 2016? Can you tell me where. Also if you look up the Lexus IS250 engine from around 2010 I think it made the list of the top 10 worst engines ever built. Lexus even extended the warranty for a few years for consumers that had excessive build up or an engine that would not run.
