- Must watch so you dont make this big mistake with a gdi or direct injection engine because the oil catch can and intake valves can give you disaster also check out my video on crc vs seafoam crc intake valve and turbo cleaner or stp and royal purple along marvel mystery oil. #seafoam #16oiltournament

You make the huge mistake of not telling us what the mistake was 🤦🏻♂️🤷🏻♂️
catch can should be closed system.. how can we take you seriously dude.
I think the mistake is how VW designed this engine with direct injection and no catch can
Still trying to figure out what the "big mistake" is? Was it you forgot about the breather hose?
Mistake is not using a catch can or cleaning valves
Glad i wasnt the only one who didnt know
@@NATESINTERACTIVEAUTO not trying to hate but I also found that I was confused about what the big mistake was. That was never really made clear in the video
@@NATESINTERACTIVEAUTO Mistake is not using the catch can.........ehm......... In the video you are using it. 😁
One of the best aftermarket methods that I have seen for GDI engines is a tuned remote port injection system which is usually used when you want to make more power but it also eliminates the carbon build up of the valves. It's basically a small aluminum piece that goes between the head and the intake manifold with fuel injector ports to spray right behind the valves. That is by far the best method, Ford now made it a OEM item for their GDI engines and Toyota has been doing this for awhile now on GDI engines.
Thanks for sharing information with the NIA community
I believe you are talking about dual injection systems. 1 injector sprays fuel mixture on the valves to keep them clean and another injector further down in the cylinder.
I've been trying to figure out for the last month on if anybody makes a kit to be able to do dual injection on a LT l86 engine from general motors and I have yet to find anything I'm also curious on how you would tune it to work
@@andrewmeek6750 your best option would be to ask a performance shop since they add these to LT engines for E85 or Spray on Corvettes and Camaros. Since your engine is similar I'm sure they can fit it in and tune it to run on par with the GDI at lower rpms
I agree with you. As you run it more n more and drain the catch can after a few 10'000 miles maybe 20k or 30k you start to see the catch can mud is less and less dirty looking. My vw gti eventually had a real light mocha color almost getting to caramel in color where as the first time drainage on the catch can was chocolate mud sludge water. Lol
Hey Nate. I have the same engine in my fprte. I recently installed an oil catch can, although i went with a vented system thinking it would be better to just vent the excess blowby rather than having it return to the intake and gum up my valves My question for you is that both the pcv valve on the front of the valve cover and the rear seem to both be letting out positive crankcase pressure. Neither seem to be sucking in fresh air. Can i run both lines to the same vented catch can? Thanks a lot man! Love your vids!
I sure hope that piston at 1:13 was an example of how to create blow by. I'm rebuilding a 77 GMC 350, I bought used, and found most of the rings just like that. There were broken rings on two pistons, because someone didn't remove the ridge. I've been driving it since 95, that way. A good example of why I trust no one with things I can't see.
Looks like we missed something here. The air from the PCV, after going through the catch can should be routed back to the intake. That way, we'll supply the engine with a little oxygen depleted air. That air along with an ECU controlled EGR valve will help in lowering pollution.
Lolol emission control
Efficiency equals power and can sometimes lower pollution in the process. But you ain't ready for that conversation I guess
STP Intake Valve Cleaner blows CRC and Seafoam out of the water. Cleaned the entire intake valve banks on a 2015 Kia Sorento SXL 3.3L V6 GDI engine, with 85K miles, never having been cleaned before.
Can you resuse that valve thing. I want the stp but can't find now and it like Tripple the price of the seafoam which works great to me. I get the stp if I can reuse the vavle if not they can keep it.
So what's the mistake? Not taking care of the engine? Not installing a catch can earlier? vague.
Good video but you forgot to say the mistake was not using the can and also how much oil do you catch per 5k mi ?
it looks to me like you are introducing ' false air ' into the system the way it is set up, this will make the car run a bit lean
What kinda catch you using jeez seems janky
Are you saying the oil catch dose not work. that you still have high sludge buildup.
Please tell me where u are looking through to see the back of the valves,
Remove the intake manifold and look down the runners. Those are probably not this guys photos.
Oil catch can vital to direct injection
Thats true
I have 20k on my GDI Focus ST and I want a catch can so bad but they are illegal and Cali and I cant get one....*sigh*
Subbed! Can you please test oil additives on your bearing machine? Such as BG MOA, Marvel Mystery Oil, STP, Duralube, Motorkote, etc.
Yes i plan on this very soon
Buy a brz,frs,86 and they all have port and GDI
That's because Toyota helped Subaru make their GDI system work properly on the BRZ.
Need to fasten the oil catch can down along with the fresh air tube. Do those rattle around while driving?
You can see the strap on front video picture
@@terryscott7563 yea but I wouldn't consider that fully secured.
It cannot even move as hood closed along with fastener
Yes
I use already drilled holes
Introducing fresh air into the engine creates a huge vacuum leak and you will run lean. Save your pennies for your engine replacement.

Blow by a serious problem if not maintained properly with gdi vehicles
Yes correct
What mistake did you make??? It sounded like you made a mistake while hooking it up but i didnt see in detail what you did and how to correct it?can you be more specific and show us
Most of that gunk on the valves is probably from the EGR
This car is the only car ever owned without egr i know required by law but because of other reasons technically the variable valve system uses exhaust gas recirculation im sure this is how they were allowed to not install
Egr can be a problem you are correct
Or the pic valve.
Yea, occ between pcv and intake manifold does a good job, but the egr is definitely doing the majority of the damage. I just cleaned my intake valves by hand, and with walnut shells and an air compressor. They look brand new again. I still retained my egr due to living in a communist state, but I slapped an occ between the pcv and im, and it's catching a good amount of oil
Your video, along with your title, is one of the most videos I've ever watched. You imply that you made a mistake in using an oil catch can, but then at the end say to install one. Your title should be something like "Big mistake not to use an oil catch can on GDI engine." Then actually explain that in the video...
It’s been out for two years
you have done it totally wrong, there are 2 hoses getting out from the head cover, one goes after the throttle, and one before, this is because one or anothe will have negative pressure, or it will suck air from the head, in order to keep it as little pressure it can be, if you step on the gas, the negative presurre change from before the throttle to after, you cannot just set a breather filter and that will fix your carbon deposites on the intake valve, the only good solution is set a eletric vacuun pump in order to have as much as you can presure that builds up inside the engine, your engine right now is more likely to leak oil from any seal because you got more presurre inside the engine with this PCV delete, think about this, the intake before or after the throttle sucks air, and this helps to take the pressure inside the engine due to blow by, or you keep PCV correclty with a 2 catch cans one for each head output(or a catch can with 2 parts separeted, or a vaccum eletric pump in order to realease the engine internal pressure more efficent(if you can keep negative pressure inside the crank case better, less resistance).
Hello, im here because im looking for the more efficient way to avoid carbon formation, the purpose of the PCV is be environmental only, back in the days cars had a hose hanging down from the engine oil cap all the way to the ground, engines now and back works very much in the same way modern engines have a lot of electronics, fuel injection, electronic distribution, bla bla bla but the core engine itself remains the same, 4 cycles, valves, pistons, levers, crankshaft, etc. Too much is going on inside the crack case, oil splaying everywhere, massive pressure over metals heat the oil and it vaporize it in small quantities, pistons rings let gases pass to the crank case as well, like i said is a lot going on in there the result is a lot of gases, mist of oil rises up by heat and vapor, etc and all this is consider pollution, so somebody invented the PCV great, PCV dont give you better performance, actually dont give you nothing more than be proud you are protecting the environment in exchange to screw your car and eventually you going to have engine problems, no the government, no the dealer, you going to have to deal with it. In my opinion modify the car to the old school way is the only way to avoid carbon formation in a GDI engine, you no necessarily have to drop the oil in the road, instead install the breathing hose to a catchcan and seal with a plug the entrance in the intake manifold. Keep the original hoses.
Concentrate🤣
I to have oil moving into intake
Do as i have in the video
If you have a pcv valve, it's normal to have oil build up in the intake manifold
whos gonna turn their car in to a science experiment
Good question someone smart trying to accomplish something. But not me on this car now only to see what can help the cars current issues.
Do you never mentioned your big mistake come on man if you make a video make it complete
I Missed the Mistake Part...?? 🤔🤔
Still waiting for the mistake tho
You don't really need a catch can. Just make sure you clean your intake valves every 5,000 miles. My car has 64,541 miles in it and i just clean them with CRC. No need for catch cans really.
I agree to a extent but i believe all cars require different levels of attention
OMG somebody who doesn't want to believe the data and wants to ignore all the signs that indicate you should be using a catch can. Another know it all! Yes you should have a catch can on GDI engines. Quit being ignorant. The ONLY exception is DUAL injection systems which spray fuel mixture on the valves and a second injector further down in the cylinder.
Thanks for watching
But if a simple catch can helps I would install it anyway. Oil into the intake also means burnt oil in the cats or particle filter (if it is the case). Also make sure you don’t create a restriction with the new fittings/hoses because it can increase pressure in the crankcase and cause gasket leakage
Omfg a 3 minute video for a 5 second problem
Dude how can people think they are smarter then engineers if the manufacturer didn't put a catch cans by now on all there cars is for a reason just follow your maintenance schedule by manufacture
The cost and why would they make a gdi with the carbon buildup issues and then add extra fuel injectors to stop the problem. Unfortunately a oil catch can will not stop the problem. Engineers, maintenance schedule the oil change is one great example of how they word the maintenance to sound better? Or more likely wishful thinking how people go with regular service interval of 7500 miles when the majority of people fall into the 3000 mile interval as the manufacturer suggests if you drive under 20 minutes depending on outside temperatures, hills mountains, dusty area , stop and go traffic, many other conditions, my favorite lifetime transmission fluid.
@@NATESINTERACTIVEAUTO I have a 2015 genesis coupe 3.8 GDI engine with 150k miles and never had an issue I do follow all maintenance requirements like change spark plugs every 50k change my oil every 5k with full synthetic oil and every 10k I spray crc to clean the valves and change my pcv valve every year so far the car has run great and I run 87 octane chevron gas with techron and once in a while I'll fill up with shell v power
@Victor Rippe The manufacturers maintenance schedule calls for cleaning the valves?? GDI positives are more horsepower.....the negative is the carbon buildup on the valves.
Actually the manufacturers put oil recuperation systems but it depends on the producer. As you can see the manufacturers did a flawed design because oil should not get into the intake and the valves should not build up with carbon. There are solutions to that: oil recuperators (then if you install an additional one it helps a bit, but don’t create a restriction so maintain the same diameter of the inner tube), and also many engines have MPI injection as well but it’s funny they actually added the mpi for different reasons but it keeps the valves clean :)
NATES INTERACTIVE AUTO in Europe the oil chance interval is 15k miles and 2years for bmw 😂
Valvoline easy gdi guy
Big mistake is…
1. i dont know what r u smoking, but stop it make you sound like...
2. clearly u get paid for marketing
about as confusing and rambling a presentation as I have heard. Got ZERO information except that your must watch reveal was that it is a GDI engine to start with. And it appears that what you have done is to just vent the crankcase to atmosphere thru the oil separator and breather element attached. This of course is how internal combustion engines were vented back in the beginning....just a simple road draft vent tube.
The worst rated video on this subject. Literally.
Crock of
horrible video of explaining things lol, didn't even explain what the mistake was or why you even let that oil catch can get so full, you are supposed to always clean it before it gets full.
No offence but I can't stand your accent 🤣
