Amazing. I wonder how many people completely missed how clever this is? [applauds & throws rose].
This is gold. 😂😂😂😂 Legend
I absolutely love how you guys post the full trips on you youtube channel. I watch the full videos from start to finish even when they are over an hour
Very informative video - thank you. I recently fitted a Provent to my Audi SQ5 V6 biTDI after doing a full intake manifold clean. I had to custom make the kit as no one caters for this vehicle despite how many of them are on the road.
Had one in my navara for about a year , im amazed at how well this works my intercooler is bone dry , no oil build up in the intake , great product ☆☆☆☆☆
What year make navara you have ?
It would be nice if you did a video looking inside a inlet manifold after using a catch can for 100k. just to prove it works!
nobody will because they don't work
You Tuber Musing Greg did a video showing that it works to a certain degree, but far from as good as a lot of people would make out
Exactly. You still get dry soot caked on I have a pro-vent fitted and intake cleaned. After 40,000 still had the intake cleaned again. Still allot of dry soot clogging everything up.

Best video of catch cans period! Thanks!
The best video I've seen on why to get a catch can
Hi, i am from Indonesia. I've been using Provent 200 for 2 of my car Fortuner 2016 and Terra 2019. I am very happy with this product. My intercooler is clean. My turbo is clean, even intake is also clean. Great product. It's a must for your all diesel engine.

Great video! Finally someone who knows what they are talking about re EGR systems! Well done, thanks 4WD Action. Keep up the great work!
if you were impressed with old grey saying how good egrs are you much think servicing your air filter means throwing a hand full of dirt in your air filter is going to make it run better because that's what he is saying you restrict airflow in a diesel it runs hotter no cooler diesels like air flow and cool air not hot exhaust gas with you think they have intercooler for to warm it up or something what old grey in video is doing is preaching lies to conform to emissions laws not help your diesel engine

really good info learnt a lot thanks dudes
Keep up the good work boys.
I wonder how a variation on the old "Kleinig" water injector from the 1950's would go, perhaps feeding a fine spray of say Kerosine occasionally into the inlet manifold, to "wash" the valves would go?
Great video. Probably the best catch can/filter system and video I have seen. If they ever develop one for the U.S. market and especially the gas engines in the U.S. market they have a potential for a huge market. I will be first in line to get one! I have a gas V-8 engine and haven’t put a catch can on for the very reason you stated. They aren’t very effective but I am at the point where what I can get is better than doing nothing... Like I said the U.S. is a huge untapped potential market. Ron
I’m in the US and have a Provent on my truck. You can just buy one.
Excellent explanation, thanks.
Those were the answers to my questions Thanks a lot
Great video. Very clear and concise. Thank you.
And very flawed too....
If I install the catch can, do I need to clean up anything in-line of the can. ie; clean out the system of which it protects?
Learn something new every day. Do you guys ship to America? Would I be able to get one of those over here in the states?
most important mod is an EGR blanking plate.
True. Oil alone make first cylinder run hotter. Combustion will burn carbon. Problem is oil mixing with soot delivered by EGR. It creates oily sooty mess, which blocks anything and stick everywhere in intake. Madness. EGR should be destroyed.
Do you have to perform a remap when you blank the egr?
@@trinidads1874 no can just egr plate. Some models u can just maf sensor bypass like dmax
If it's so important to install a catch can on engines with an EGR, why don't they come stock? The EGR on my Ford Everest failed after 135,000km and cooked the engine for a $25k repair bill. EGR is the worst addition to diesel engines sine their inception
@@maxxfx4767 because EURO V and VI emissions which manufacturers abide by in order to sell their vehicles into Europe do not take into account countries that do not see snow. Further more, you can drive for 5 hours in any direction and pass through 2 or 3 countries. In Australia, 5 hours drive would not even get me anywhere near my states capital city. Engines for Euro specs are only designed for short start\stop....not long distance driving. hence why aftermarket addons are needed on vehicles that meet Euro specs but are sold in countries outside of Europe. My town hits a maximum of 42 degrees celsius and roughly 5 degrees celsius in winter. 5 degrees C in winter only happens once every 3 years, usually our average is 13 - 15 degrees Celcius for the winter months. Engines in Europe rarely get to operating temperature before they are shut down and the driver reaches their destination.
Sold once again, you guys keep on delivery the goods haha built not brought 💪
Hi Rainer, I fitted a Provent to my New Pajero, from what I got out of your great video, you recomend not to blank off the EGR and I assume this mean by plate or lectrically using a EGR delete harness,,,, EGR DELETE KIT - MITSUBISH 3.2L ENGINE (PAJERO 2017 ONWARDS) many makes on the market. could you clarify please catch can only recomended or also use EGR delete cable? thanks heaps, great video.
Fantastic info guys👍
Great video and very well explained the problem. Do I get trouble if I install this ProVent Germany? Do I need it get checked by TÜV? I’m worried about losing my insurance.
That was a really good video.
This is 100% my point why Chemical cleans are no good for an engine, all that built up crud gets forced through all the area's you pointed out. Cost more for a mechanical removal and clean but all that crap goes in the bin and not through your engine. Catch can can only do there job if fitted from near new, There great, but for a slightly older rig the mechanical clean must come first then fit the can. Now let the money making chemical cleaning guys unleash and tell me where they recon the crap goes if not through the engine, Thanks for your video Murray in Redcliffe QLD.
Interesting vid but also opposite to what my mechanic has told me with the D40. He says egr block is the way to go and I don't need a catch can after that as the oil will burn off properly not mixing with the exaust gas. He also said the opposite with fuel consumption as everyone they have done the egr block on has reported better fuel consumption and performance. Be nice to get some consistent answers
Change your mechanic. He's an idiot.
I am a mechanic and I agree,block the egr then the oil vapour won't mix with exhaust gas and won't gum up.Tiny amounts of oil in the intake is fine,will just burn up.The downside is you won't be supporting commercials such as this
@@renbenism My intercooler was literally dripping with oil after 5000ks. The oil mist is harmful to the turbo that it passes through and coats the intercooler so it doesn't work nearly as well and it coats the inside of the inlet where the extreme cylinder heat will bake the crud on, even without the addition of EGR. The crankcase blowby fumes are not pure clean oil - the collection of trapped fumes that comes out of my Provent is disgusting black oil. I remind readers that 50% of mechanics are below average, and I remind readers of the oft publicised videos that trap "mechanics" ripping customers off. Message is don't trust a mechanic because he says he's a mechanic. Think logically. Fit a catch can or sell your vehicle before 100,000-150,000ks.
Over 300000km on my patrol with out a problem and 17yrs trade experience being a diesel mechanic I guess I know very little on the subject,might fit a hi clone aswell.thanks for the enlightenment👍
@@renbenism Mann-Hummel has 75 years of experience and is a massive company. Yet you claim to know better. I know who knows more about catch cans and their benefits.
Thanks for the upload. My patrol just out of warranty and I finally convinced myself to block EGR......now I'm confused again....Ha ha. Definately getting a catch can.
Andrew Munson leave it blocked!!!! If u have an engine light on drill a small hole in ya blanking plate so it gets a little signal to fix ya engine light. 👊🏻.

@Kelly Petty ha ha ha......I ended up tuning it out and a remap......but the old patrols been gone for over a year now.
Very informative....intriguing video
How does the catch can affect your new vehicle warranty and why does the new vehicle not come standard with one fitted?
Whats the best way to clean it without stripping the engine before installing a provent?
Great vid!!
Really helpful video!
I AM A HUGE FAN OF 4WD ACTION GREAT VIDEOS THANK YOU GUYS! The Manufactures now build cars like throw away cigarette lighters due to fact most of the engines are no good unless you mod them cough cough, they have DPF fitted creating higher engine temperature due to the restriction in the exhaust an EGR that recirculates all the dirty final emission output especially when they are not closing correctly causing smoke less mpg and higher nox! ohhhh and mr Mann filter man..........an egr recirculates the hot exhaust gas so this make the burn temp higher not lower !! I do like the catch can though its good that the crank case oil is not been allowed to enter the combustion process
I've read the opposite, that since the exhaust gas that recirculates is always losing heat after combustion, the EGR allows _cooler_ temperatures in the cylinders, _not_ higher. This makes more sense logically than what you said "makes the burn temp higher."
If this is such a problem why don't manufacturers put this in as standard?.
michael george cause they get more money out of an engine that is designed to fail. More work = more $$
I'd say these days engines are designed to last until warranty ends then they shit the bed
The oil in intake is not as big as issue everyone makes it out to be, its the exhaust gases that sticks to the oil that carbons intakes up. It's just another "service " item to there list for manufactures
I was wondering the same thing. Will be interested to see the answer.
michael george same reason why some manufacturers are stretching out oil service intervals to 15k -25k or up to 1-2 years between services. They don’t want the engines to last, In other words.. More money in selling new cars than keeping old ones running around.
If you already have build in the intake ,does it go away after fitting one of these? Or do you need to have it cleaned out first?
I had a look at a EGR system with a catch can. It still had plenty of carbon deposits. It may well slow the deposits down as it catches the oil and the soot has less ability to stick to the EGR components and the inlet manifold, but I wonder if the small amount of oil that gets through without a catch can, helps to lubricate any deposits that make their way into the cylinders? Essentially, is the grit post catch can more abrasive as a result of the oil removal?
@Charles Martell did you just watch this video at all.
Great video!
0:47 Lots of blockage and performance loss after just 2,500 kilometers?! Give me a break! Surely if that were the case by the time the vehicle hit 100,000 kilometers it wouldn't run at all, or the owner would have spent $40,000-80,000+ in repairs to fix it.
thank you detail video
Thanks for this info but im sorry i just don’t really understand any of it. Seems very important but Pardon my ignorance, i had a new mu-x and i wanna know where i could buy one and have it installed. Does this connect between the air intake and the engine? Just not my forte, but thank you in advance for directing me in the right path..
The explanation of how EGR "saves" your engine by de-stressing it is pretty much a politically correct discourse. Yes it reduces NOx emissions, but NO it doesn't give an engine better economy or longevity. To cruise at a certain speed requires a certain amount of energy from the fuel - if you reduce fuel and O2 by filling half the chamber with inert gas you reduce the power output and hence the vehicle will slow down until you press the accelerator further to add more fuel again. Your economy actually gets worse. I've had a Provent on my Patrol since 5000k from new, and the inlet was already saturated with oil - dripped out of the intercooler when I took it off to wash it out. The Provent is indeed an elite quality catch can/oil separator.
Not sure if the guy knows how diesels operate vs gas. If the ECU is actually reducing fuel, your right foot will be compensating. Give me all the oxygen and all the temperature, the NOx can be treated in other ways.
exactly. The engine breathing in soot is just destructive to its internals.........and less oxygen thanks to EGR works against all the progress in turbocharging and intercoolers to increase oxygen density. Talk about politically correct bull manure.
So the egr lets less oxygen into my cylinder therefore my engine burns less fuel. Never have I heard someone say you to restrict oxygen and fuel. Wouldn't putting a plastic bag over my intake have the same effect without the extremely hot exhaust gas being reintroduce into my cylinder?
No worries with my HJ45 H motor... It could use a catch can to stop it venting out into the environment. Chassis rail likes it apparently!
Very informative. As blanking off the EGR valve is not a good idea, does that also go for a EGR delete cable such as the Munji brand?
David Hunn I’d say so as I have one on my Holden Rodeo for some time now as I’m planning to do a full carbon clean to the engine as a precaution I think now it’s is the time to switch over to a catch can setup. More on the peace of mind, don’t get me the wrong the cable setup is great but going off that technician he definitely knows his stuff.
This doesn’t stop the egr cooler from failing and pumping all ur engine coolant out ur Exhaust or you could replace it every year
Hello, Great video thank you. Do you sell this catch can for the 2002 2.0d4d rav4?
What would happen if you did an egr blockoff and installed a catch can?
It blows me away that what seems to be a simple and relatively cheap fix is not just done by the engineers and vehicle manufacturers as standard.
Schmidt Head Spearfishing yeah it is crazy but it becomes something the owner has to monitor and maintain and that adds an element of human error which they don’t want.

Hi I have recently had a catch can installed about a month ago all I have had is abit of water come out when I drain it. It's been opened up and has a build up of grease around the rim of the catch can. Do you know if this is a problem for me in the near future? Is it doing its job?

Where do we get the 1-inch to 3/4 hose reducer? Thanks for a great video,.
If all I need is a catch can.... why does the egr valve block up in the first place? when the egr is straight from the exhaust, before any oil vapour comes into contact with the system from your crank case vent??
Great vid
Is this catch can you're talking about is the same as the oil and water separator? PCV valve?
Love mine, money well spent.
So your putting burnt oil back through the pistons cycle, so it lowers diesel consumption and pressurises the crank case! Why not just have hho run back through? (because the o2 sensor sensors fuel and supplies the right amount of diesel). Then you can catch 100% of the oil, it would still lower fuel consumption and be 100% better for environment and the engine, and the oil discard process might be higher but a lot easier and the whole system works better all round?? 💁🏼♂️ Can an egr sensor be deleted from ecu ? And can it “sense” Hydrogen as a fuel or be changed to do so??
I wish I had this problem on my 79 series but cannot get them in the states.
Blanking off EGR, Toyota D4D and turbo going on 400,000kms. Thermal stress? Maybe I should use less right foot. Trouble with the police? Yeah well mote security less freedom. If a catch can fixes this defect, it is a defect, then this should be a class action law suit against manufacturers and a catch can should be standard fitment on diesels
You sound like the conspiracy theorist type.
@@1989cranston just logic. If an engine is almost destroyed in 100,000kms then it's an issue for the manufacturers. If they are approving catch cans, they can have them fitted when new
It’s not the manufacturer fault, it’s forced on them by emission laws...
Still no reason Joe Public should foot the bill. Unless, for reasons I cant fathom, one likes taking responsibility for problems not their own and paying for it
@@King88_8 The reality is that Joe Public pays for EVERYTHING in the end.

I use oil a catch can and a "oil bypass filter"on my diesels.
Is this issue only with common rail engines or does it happen with older engines like my td42t??
If some of that residue sludge breaks off and goes into the intake does it just get burned away?
Landcruser 200 series in my country comes without egr from the factory. Do I need to install a catch can in this case?
Guys I need some help here. I have a 2015 Mazda Atenza AWD twin turbo 2.2L diesel and I just cleaned my EGR and Manifold. Which of these catch cans will work for me?
Having an EGR is like forcing your car to eat its own shit.
I installed a catch can and did EGR delete. Then I did an intake clean and also remove D swirl flaps coz they're known to come loose and get sucked in. 79k km. It was pretty sooty. I'm still concerned about valve seats and piston heads.
Did you remove the EGR completely from engine, or just get it turned off in the tune, or use blank plates.?
If EGR is good for engine then why some people blank it they says that it lesser the engine life whats ur opinion on it....
Never been a big fan of compression ignition.(diesel) .Next one i buy will be a Y62. Albiet with a bit more fuel use .
Direct injection petrol engines have the exact same problem ad diesels. There ya go.
So...one good question....WHY do manufacturers not pre-install a Huge Catch Can.....its not like this is not a known issue and that skirting the simple installation of a catcha can will save money..... epxlain?
Just make sure when you take your brand new car in for its regular service that you remove the catch can like i do. I heard from very reputable source (they work for Toyota) that if a catchcan is spotted on the service they void your engine warranty on the spot. So i just remove and give it a clean prior to service. Then after i pickup my Prado its back in place in roughly 20mins
Well this is interesting product didn't know it exist. But does the installing of catch can ruin the guarantee of a new car? And can it be mounted in diesel hatchback not just big 4x4
Easy way is to ask vehicle manufacturers service department. Yes will need custom kit for hoses. Don't buy a fake provent get German made mann hummel provent 200
Is there a kit for the ford transit custom with the 2.0?
Can these catch cans be fitted to a 300 tdi defender ??
The catch can is somewhat not a very dependable solution since the oil vapour from the blowby gases makes the soot from the EGR stick on the inlet assembly instead of it going directly into the combustion chamber where it can be abrasive to the cylinder walls and piston rings. Just clean the intake assembly after 80,000 kms you'll be fine. Instead of prematurely wearing out the cylinder walls and piston rings which is more expensive than cleaning the just cleaning the intake.
I have heard this argument before, but I believe it has an obvious flaw to it. If the exhaust gasses are abrasive to valves, cylinder walls and rings then consider that these components are exposed to exhaust gasses constantly while the engine is running. The only engine cycles with little to no exhaust gasses present (EGR gasses present in the cylinder) are intake and compression. I tend to believe it's far preferable to avoid choking the inlet with a soot and oil mixture.
He is referring to the soot being abrasive, not the gases @@pauldarlington5589

Hi all. Do i need a catch can on a 60 series 2H.THANKS.
Would fitting a catch can to a brand new vehicle void it's warranty?
good video mate
I would consider getting one of these but I know it would void my warranty and if I had any engine problems at all, the manufacturer would walk away. I would then be depending in the insurance of the professional that installed it. If I did it myself I would have no chance.
They would have to prove a catch can caused the engine failure which is garbage. Catch cans prolong the life of diesel engines.
I am surprised manufacturers don't include oil catch cans!
Because it does more harm than good. Hence why multi-billion dollar vehicle manufacturers don't include it. They know more about their own engines then these diesel specilast who just want you to buy there products. You want that oil in your intake to capture the carbon soot coming through your egr so it doesn't wear down your valve seats
@@thedescriptions6646 if that was the case, why isnt this a problem for the exhaust valve seats which cop the soot 100% of the time? Also, is there any data available on heavily soot impregnated oil and its lubricity?
