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 ?
How much oil can a catch can catch, if a catch can can catch oil?
Up to 98% apparently.

Amazing. I wonder how many people completely missed how clever this is? [applauds & throws rose].
This is gold. 😂😂😂😂 Legend
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.
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.
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.

Having an EGR is like forcing your car to eat its own shit.
You’d lose weight and digest your food more efficiently though.
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?
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??
All diesels from the last 30 years have had the oil vapour fed back through the intake. The egr is the main culprit. Block that fucker off and happy days!
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.
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.
Catch can helps like 5..10%, the EGR gases is the main issue, I got a catch can and it catchs some oil, but that does not eliminate the soot on the intake and EGR valve as the gas from the EGR has sooo much oil on it, diesel engines are designed for long time running, I had an mwn diesel bus that ran everyday from 4:30am till 12:30 every day from Mon-Sat, 2 drivers and it has never any issue because it was always driven like pedal to the metal, hard working lot of hours 400k in 5 year, urban drive 14km each trip, probably 15..18 each day
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.
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! 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

@@carlmenzel8744 100% you're right, but to get your point across a little better, you should consider the use of some full stops and commas.
@@bumndrass hahaha exactly
When doing something ‘illegal’ is good for your engine
Incorrect! The problem is the EGR soot. You need to reduce that by a blanking plate, generally a 7mm to 8mm hole blanking plate will significantly reduce build up. You have butterfly valves and the valves that need lubrication from vented engine gas. Diesel use to get this lubrication before direct injection. Now diesel is directly injected it bypass the additional lubrication diesal inlets need. Reduce EGR soot and leave the oil, the oil will act as a cleaner and remove the reduced soot. Taking away the lubrication the soot will still cake your inlet. Reduce EGR and keep engine gas recirculation. It's minimal oil! Have you ever check your oil and noticed it dropping? No! If your worried about intercooler reducing its cooling efficiency, pull it off every service and high pressure clean it out. It's only 4bolts and 2 hose clamps. Again it's not blanking it reducing EGR by 90% it still gets through just slower
This is a good point everyone may have missed if it's true but what you are saying is that the swirl-flaps fitted in the inlet manifold need lubrication from the blow-by oil?
7:05 to 7:30 mission impossible! He don't know what he is talkin about. There is no way to eliminate oil vapors unless you have equipment that cost a fortune Both is illegal. Party begins when exhaust gasses mixes with oil vapors :)
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?
What a joke. You don't need a catch can, majority of what it catches is moisture. The minor bit of oil it catches is harmless, 20mL at most over thousands of K's. The prime culprit for this buildup is the EGR NOX itself, which can easily be reduced to harmless levels via an EGR flow reduction plate which you can grab from KAON for $10-$15. No dirty exhaust fumes, no caked on build up on the intake. Stuff paying $400 plus labour for a catch can that picks up a bit of moisture and can cause more problems then it fixes. Also how does an EGR lower temperatures? The air coming out of your exhaust isn't cool at all, its purely emissions.
"How does EGR lower temperature?" The theory is that it partially extinguishes the 'ignition' (by 1/2 filling the cylinder with non combustible gas) making it a less volatile burn. The recycled gases also go through an EGR cooler before they enter the intake.
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.
Can I just vent the catch can to atmosphere instead of rerouting it to intake manifold ?
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

I can't tell if they're saying EGRs are a good thing because they have to or actually believe they are.
Gezz the droplets coming out of my 4gj2 are about 1mil to 2mils in size. That paper filter would last a week
34 years as a heavy plant mechanic all I got to say is the egr and dpf is just a load of political eco bull get rid of it your engine will thank you for it,
Yep. I have seen oil change intervals go down and fuel economy go up when these systems are deleted. Youre right, this stuff just doesnt make any sense at all. The part about the engine living longer made me laugh.
@ferkemall exactly! Its been proven that the person who started it here in the US was a fraud and blew all the statistics way out of proportion. But the gov is making so much money off it they'll never let us go back.
Makes sense to me. Let it breathe fresh air and diesel and blow all the crap out the soot pipe. I do hate diesel though. They make me feel instantly sick and I smoke cigarettes all day. If people were a bit considerate and didn’t go rolling coal everywhere to race up to the red light in front of them it wouldn’t be an issue. Or leave their old diesel running for five minutes parked in front of cafe on Sunday morning while everyone is having breakfast. They’ve jumped at these laws to make more money because of the idiocy of a few. Don’t get me started! Isuzu trucks used to go forever ♾. Not with dpf and egr systems they won’t.
Diesel fumes I meant to say
yeah same story with lead petrol. don't care about other people's health and the environment.
Catch cans don't help this situation lol it just makes the soot dry making it harder to clean.
EGR block is the way to go
Less soot builds up when there is no oil
Those were the answers to my questions
Thanks a lot
Delete the emissions you dont like eating your own crap neither does your diesel.
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.
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!
So the EGR doesn't engage at full power and at full temperature but its suppose to reduce engine temperature........riiiight..
i have fitted a provent to every diesel I've ever owned, currently have 2. Still makes you wonder why theses aren't fitted standard as new from the manufacture??
it will cost more but won't be a point to sell higher price because 99% of buyers don't know it
Cars never use to be this way , but the environmentalists insist on it.
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.

Dead right Mate, a bloody blocked EGR valve is like trying to have a poo with your thumb up your bum hay.
Great video & keep spreading the word Mate, Steve.
But an egr is like having a pipe up your bum going to your mouth
@@lifeofjimmy9668 hahaha guild I😂
Don't get scammed by adding a catch can.. the oil is important part of lubrication and cleaning process comes down to poor maintenance, irregular oil changes and worn injections.. this is only a band aid patch job, look deeper into the real issues
Catch can is the modern engine fix snake oils!! It could severely damage the engine when it fails, and like so many other engine parts, they will fail and the cost to repair the engine will run into thousands of dollars.
And change oil regularly helps 😃
Great explanation, thanks. Does fitting a catch can affect new car warranty in my case 2022, Toyota 79 series V8 ?
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
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

Question: if an oil separator is so effective, why don't manufacturers fit it at the factory?
they aren't fitted as standard because 90% of people wouldn't empty them at the intervals they need to be emptied. sucking in actual liquid oil would cause more damage than oily gases.
@@UnacceptableViews well, they could've make it part of the service schedule (like checking/replace mthe PCV valve since the 70's) it is like who the hell will clean a MAF...
Hence I've removed the EGR from my car to save it's engine. F the climate change brigade. It clogged my intake so much, it almost destroyed the engine. Less than half a 5 cent piece.
Why dont manufacturers include catch cans from new?
Because they still have to vent the pressure from the crankcase somewhere and the only legal place to vent the pressure is back into the intake. Effective filtering is at odds with relieving the pressure from the crankcase. A filter that catches every last bit of oil will be too restrictive to prevent pressure building in the crank case.
That's why most aftermarket catch cans vent to atmosphere because it completely solves the dirty intake issue and they don't care if some oily vapours make it to the atmosphere - they are however illegal.
A complicated catch can also adds extra cost to producing and servicing the vehicle and every dollar is important if you're in the business of selling and servicing vehicles.
TMM if you watch closely the catch can only catches the oil and the blow by pressure still goes into the intake. So I can see why he said why don't manufactures do this from the get go.
@@lukepaul2882 yes, so it does not completely solve the problem. Less oil will make it to the intake but there will still be some oily vapours vented into the intake and the crankcase pressure will be higher as a result of the restriction that the can makes. Whether or not this is enough improvement that it is worth doing and doesn't cause negative effects I couldn't tell you.
A piece of the picture nobody seems to mention is the answer to your specific question. The answer is because if the oil catch can is not maintained properly, this can cause more damage to the engine than not having an oil catch can in the first place. As some people mention, many people do not regularly service their vehicles properly or enough. This introduces a very real problem and concern for the manufacturer to deal with. In addition, unless the vehicle is Direct Injection, the issues created by not having a catch can are typically not an issue until after the car is out of the warranty period. In the case of Direct Injection vehicles, some manufacturers are utilizing other methods to stem a part of this problem (typically carbon build-up on the valves in particular).
Thanks for the replies TMM and stephen commando. These sound like valid reasons why a manufacturer might not fit one, even though they are beneficial. Just trying to disentangle the marketing from the facts in this video.
It would be good if you lot wouldn't think that a plastic container doesn't cost $ hundreds and think its gold plated.

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?

How does the catch can affect your new vehicle warranty and why does the new vehicle not come standard with one fitted?
if your getting that much oil in a catch can after 2,500k's you have a major problem with blow-by or pressurization of the engine, and catch can is only a band aid job and not going to solve or fix the issue.
Turbo diesels from new all breath oily fumes.
AGR makes engine life longer-what a bullshit! lol Delete -makes live engine longer))

Catch cans don’t work. If you want to prove they do, show me the internals on 2 new engine brake downs doing the same driving under controlled conditions after 5000km , one with and one without a catch can and prove the effectiveness of a catch can.
I've worked on hundreds of diesels and every one fitted with a catch can has much much less oil through it and the catch can is always full. They are very very effective and should always come from factory, especially with turbo diesels as most intercoolers become extremely ineffective
@@achilleaustin The cure (catch can) is the worse then the disease!!
What will be the consequences if the catch can fail while you are driving? let say the PVC cracks!! how do you get alerted on your dash that your catch can have malfunction and you need to replaced? what if you forget to drain it? or sell your car and then next owner doesn't drain it? what kind of test and quality control have the catch can gone through?
Do you seriously think a $200 PVC can will fix a complex engineering problem that engineers at Bosch, Toyota, Ford, VW, BMW...etc could not figure out with all the resources they have at their disposal? if catch can was a viable solution this companies would have sell you million to people as accessories.

Great vid
Dumb question, how come these are not sorted out by the manufacturer? As in what stops them from installing a catch can from the get go?
1. The engine will last the warranty period with or without one, saves them money to not fit them.
2. As the expert said, it needs to be maintained (emptied) every 5'000kms. If its not emptied and becomes full, it causes bigger problems - excessive pressure build up in engine and can damage engine seals.
Why didn't car manufacturers just add a catch can in the first place
Planned obsolescence. Its engineered to fail so we spend that $$$$$!!! Modern day slavery at work, debt slavery.
Scotty Kilmer answered this question - it's just too much work for the "average" person to attend to. It's just another thing people need to maintain and it's hard enough to get people to do regular oil changes as it is.
@@canyonoverland5003 what do you mean mine drain direct to the sump never have to lift the bonnet
Number one reason is because it costs money, and manufacturers don't see the need to prevent problems that will only likely come up once the warranty is over. It usually won't give problems until 100,000km, most people buying new cars don't know what a catch can is or don't care, so they save their money and go without. Also having a replaceable catch can filter adds to the cost of service, and this is something manufacturers want to reduce because customers take this into account when buying a vehicle. Same as why they have long oil change intervals and non-replaceable transmission oil.
@@cbishop41483 spot on
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....
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
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??
I use oil a catch can and a "oil bypass filter"on my diesels.
I don't know what everyones problem is with egr and catch cans iv had 2 cars now with them oldest being a 2010 and 0 problems one I put 200000km on it the egr never played up and the intake was squeaky clean the second I got second hand egr played up the first 2k I reset the code that was 50000km ago still no problems with the egr
It appears to me that it is long overdue that car companies should be fitting these from the first build ... OH !! sorry .. that means their vehicles would last longer and do them out of money.
Good presentation
Egr blanking plate job done
Yea but your intercooler still get coated with oil when you block the egr valve.
Begs the question - why a catch can is not designed into the engines.
block the egr in MOST diesels with them in my opinion. It's really only certain engines that NEED it blocked. i.e i would block it on a ZD30 nissan patrol engine but not on a hilux 3L engine.
This couldn't be further from the truth, the 3l d4d engines are the ones that the egr blank the most
This is why I'm done with diesels. Petrol models are now cheaper and last longer. My V6 ML doesn't have any of these problems and the oil last 15,000 ks
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.
@@callumwhite1501 to me its no different to checking fluid levels or having your car serviced, theres always going to be people touching the car after after it leaves the factory.
I agree but there’s a large amount of people who struggle to keep service intervals or even topping up there washer fluid.
@@callumwhite1501 haha yeah thats very true!
An EGR is one of the worst things put on a Diesel engine.
Cheapskate owner will always think the best way is to ignore it
