Very helpful advice, Brett. Having just recently myself invested in a Triton, I'm re-learning about diesel engines after 30 years and getting to know all the new tech. Plus, the delivery of information is far better these days with access to videos on KZfaq. Tremendous help! Thankyou all so much.

I must say Brett that this has been very informative as I am in the process this week of have upgrades done to my 2016 Ford Everest with 43K kms on the clock.I was suprised at the amount of soot build up in the manifold for such low kms. Articulate and concise no BS and in layman terms . Appreciated . 👍

It also coats the intake valves and, because of the heat, it gets baked on and builds up and restricts the air flow into the cylinder. Free air flow is critical for any engine but specially for diesels.

Extremely well explained. Sounds like i need one for my 7.3 powerstroke.

Mate another great educational vid. Amazing you can do all this in one take, shows your knowledge of these systems.

Can’t get any better then that. Explained plan and simple for anyone to understand. Good work

Awesome explanation, really enjoy watching your videos and hearing your thoughts.

Very clear and informative, many thanks. It is refreshing to have someone who knows what they are doing share a high quality video. Keep up the good work.

Very formative, I finally understand now what an oil catch can does.

Great explanation and concisely presentation! Thanks for making this!

The explanation is correct and very good the way of the explanation on the difference between petrol and Diesel engines turbo and not turbo. I think the engine you are standing by is 4n15 from Mitsubishi

Thanks. Nailed it. Not the catch can. Great work on explaining. Confirmed my experimental notes. Now break pads.

Great pointers ,well done.

Excellent video Brett! Same issues with older Tdi Land Rover engines Will do a shout out on my channel soon! Mike

Great explanation, crystal clear!

So good to listen to. Clear precise info well spoken word Many thanks

Great video. It’s my first diesel so this is very helpful.

The best simplest explain action:-) thanks

The underside of my fairlane was coated with oil from the straight vent hose just hanging down by the suspension so i made a catch can out of pvc pipe. It had a 1 inch drain valve under the front bumper. I had to remember to drain it off every 300kms and pour it back into the sump. The carparks of 7/11s across thailand often featured a little puddle of oil from the drain off valve after emptying. Eventually after a couple of years i got pissed off with grovelling under the car so i put my boot right into it on a 950km run..... we got 935kms before no.3 rod popped out to say hello! .....just waiting for another isuzu 4jh1 engine to arrive from japan and the next catch tank will auto drain to the sump.

great video, know is a Breather Tank better than catch can and aplicable as well for triton? do we need to install a valve for negative pressure?

Additionally you can install a Trottle body low pressure injector. The fuel pump delivering fuel from the fuel tank on a gdi has approximately 4-5 bar of pressure, so you can split the fuel line and send it to a throttle body injector. Then you could connect it to one of the electrical lines of one of the injectors on the car. This way it will spray into the manifold and clean the valves. But that can affect the mixture so the computer will compensate and send less fuel but it may not run properly so you need a switch to turn it off after a short time. It’s equivalent to cleaning the valves using a spray except you can do it much easier and more frequently. This needs to be done buy a modification specialist and it’s only an idea of what can be improved. But maybe it’s better to start with the OCC and spray maintenance then after say 7 years install this.

Well explained. When you put the filter in. Do you just sit it in the hole. Or push it all the way in. As i am unsure what to do. Cheers

Thanks Brett Very informative, now I know what I need on my KUN26R

Hey Brett. I live in Toronto Ontario Canada. I have a ecodiesel 2016 ram 1500. Just had the EGR replaced as well the intake manifold. The manifold has the butterfly filled with soot and caused the actuator gear to crack. Due to the emissions I have to leave the EGR on the engine. What’s your recommendation to stop the oil blow by. Is there a kit for this engine specifically?? I have 147000kms on it. Please advise. Thank. By the way excellent video.

I have a Mitsubishi 3rd Gen Montero Sport (called Pajero Sport in some countries) which I believe is built on the same chassis and has the same engine as the latest Strada (Triton) shown in this video. I heard that the fittings on the OCC for the hoses should match the size of the current OEM hose. What OCC would you then recommend for this specific setup other than the one shown in the video?

Wow! Great explanation. Well done.

It’s pretty working on my 1gdftv diesel motor, I ‘be bought new one on 10 kilos on clock and I have cleaned at 10000 kilometres, my catch can was collected full of dirty grease oil combine with some water inside that engine.

Brilliant teacher indeed.

Great video, looking at this for my Mq Triton

And what’s your suggest for the toyota 1KD-FTV engine on toyota prado or fortuner on some country? Do i need the catch can? I was wondering what is the difference between oil catch can and oil catch tank?

Great video. Can you fit dual catch cans? Would that help or work?

Excellent explanation, thank you. 👍

Would this work on a 2.8 diesel 2016 GMC Canyon

Does the sizes of inlet and outlet of catch can matters? My OCC inlet is 15mm with 10mm outlet.

Extremely helpful thank you

Nice one thanks. If you haven't alredy, do one on fuel pre-filters please.

Hi, Bret. I’ve got a Jeep Grande Cherokee 3ltr Diesel 2018. It’s very tight under the bonnet for space have you ever installed a Provent or a Ryco catch can in a vehicle like mine. Some Jeep owners have suggested they have done it,but I don’t know where?

What model or type of catch can can I use for a 4m40

Do I need an oil catch can for Subaru XV ‘19 ?

Very informative!! Thank you.

Are the ProVent catch can better than the TerraTuff? I am thinking of getting one for my Mitsubishi Triton MR. Please, any advice?

Is there any benefit on a Subaru diesel?

Well explained, thanks !!

Great information 👍👌

This is why port injection is still better, at least it cleans the back of the ports, and in petrol it really isn't an issue. The thing people don't seem to understand is that a lot of blow by really only happens in older worn engine or modified engines. It's also a sign of something no working right / worn. If people do install a can make sure it's big enough to not cause any back pressure as it will make seals leak or you can even blown them out. Keeping maintenance up and replacing oil at every 5k/10k is so important in diesel. Also most modern rocket covers have some sort of oil / air separation happening as well before it's sent off to the turbo.

I have a series 5 L200 Barberian. do you sell the Catch can kits ???

G'day, just viewed this video, excellent! There is a 2001 Prado T/diesel on my 'horizon', hence the interest. I've been driving a 1990 Volvo 240 for over ten years on extensive outback trips on dirt roads and some tracks. It is fitted with an oil separator box which drains the collected oil into the engine sump, this is a 'red block' engine with over 300k on the dial and imperceptible oil consumption. With the current oil catch cans why not drain the collected oil to the engine sump? Thank you. Stephen C.

Awesome, loved it. Thankyou

Can you figure out how to put one on a ram 2500 6.4 hemi , everyone says you can't.

Thinking a lot of GDI engines suffer from the Carbone's up intakes believe from the PCV valve system. Do we have to fit catch cans, or can it just be vented direct atmosphere by running a longer pipe to the underside of car.

Be nice if you could get a pressure differential sensor across your catch can just in case you forget to drain it or it prematurely clogs or restricts for whatever reason.

Do you ship to USA?

Do I need a catch can for 2014 outlander Mitsubishi diesel

What catch can do you suggest for my 2021 GMC Sierra 3500HD 6.6 Diesel? Been shopping around but no luck...

Hello, Would you recommend an Oil Catch cabin for a Toyota Hilux Vigo 2009 model?

Do you sell these catch cans? Where can I buy?

When fitting a oill catch can` does it also have a regulater on it so the Air intake and crank case pressure gets regulated,as the gasses can build up pressure, Or is that only for the catch can trap that allows oil to drips back into the sump

Hi Guys! I instaled an oil catch can on a ford Powerstroke 6.4 because there was oil on the intercooler. But i think after installation it started to burn oil through the exhaust. Does that makes any sense? Maybe too low pressure on the circuit and doesn’t goes through the turbo so it gets burned? Its usually at low rpm, when i am on the highway up a hill or flat its fine. But after traffic or iddle for a while it smokes at low and high rpm for a bit and then nothing, it looks like clears wherever its stuck?

How did You bend that hoses?

Im having issues with my Mitsubishi pajero TD. I had to cut the inlet hose and run it through the bottom of the engine bay so it can release the oil outside. Makes a huge mess outside but hopefully this catch can helps

I have a small leak coming off my turbo in my d40 navara. 2014. The turbo is performing fine no loss of power etc. Can this catch can assist in containing the oil that is leaking?

How big of a catch can did you put in this engine?

Where tp buy thos catch can and hose for same engine. Though for pajero sport. Thanks

The best educational video about catch cans out there. Thanks.

Is it okay to vent the occ outlet to air?not back to turbo inlet?will it cause issues?

thoughts about catch can with vent out setup?

Hi. What catch can should I use for my c class w204. Engine is a 3.0 v6 diesel commomrail with a turbo charger. Engine code is om642. Thank you in advance.

I blanked my egr with 2 plates via cooler..can I put the egr back to normal by installing a OCC on my 4d56 Montero GLX 2015 to eliminate gunk build up in intake manifold.

Thank you for the video. Do you have a catch can size you would recommend for a Chevy Colorado 2.8L duramax diesel?

Excellent explanation, I have a 4m41 Mitsubishi Shogun DiD with over 200,000kms, has been dripping small amounts of oil from the Throttle body whenever the engine runs, so would say I'd have to top up about half a litre after 1000kms or so. However the curious thing is the power is still very much intact, does smoke but clears as it moves. Exhaust manifold is also clogged with carbon. Will be looking for a catch can even more so after this video, once again thanks very much.

I ran a can on my last hemi Ram for 300,000 miles and it collected a lot of crud and water vapor. Have had one on my Ram Ecodiesel for 160,000 miles and it catches about 1/2 the volume of the gas motor, Kinda makes sense as the diesel is about 1/2 the displacement of the hemi.. Gotta help keep a lot of crud out of the intake and intercooler. I drain about every 5,000 miles, maybe a bit more often in winter.

Danke super erklärt habe 👍 vielleicht habt ihr auch auf meine Frage eine Antwort??? es geht um den zwei Liter TDI..Macht es da Sinn eine Öl catch can zu montieren? Bitte um eine detaillierte Antwort. Danke schön

Do you ship to the Philippines?

Is there a filter in the catch can and you need to start the truck and show the vaper coming out of the engine and people need to start using a oil the better then a 5w30 in a diesel car or truck Especially if you live in a hot climate

How does this fitment and tune affect the new car warranty?

Is any of this "circumventing" of the emissions control systems actually legal though? Surely there is an adverse effect on the engine emissions of vehicles that have had these alterations?

QUESTION,totally out there but please look up Peugeot 207 1.6 hdi and please help on where would be best place for a catch can and how to make it automatic empty..you seem to know what yr talking about.? Surely a catch can would help with uk emissions laws..cheers lftyr..

Thanks for explanation 👍

I have a Ford Ranger/BT 50 2.5 Year 2008 that looks lije this "rocket cover breather system" does it mean the have no PCV valve? Ive got come oil in the turbo intake and I think its coming from the hose form de breather that goes in the air system

Good information man

After watching your video I might install OCC on my 2017 Pajero/Montero sport A/T. Kindly advise. Thanks and more power.

What's a good brand of occ for 4n15 triton?

Hi Matt, always interested in your diesel videos as I have a XV diesel. Do you know of any problems with oil pooling in the intercooler which then gets slurped into the engine, causing an over revving problem?

Another great informative video. Thanks Brett.

Thanks, good info! 😎👍

I knew all this but watched anyway. Well explained, well done. I would suggest using only group 4/5 engine oils for even better blowby control in a mechanically sound engine, use of a catch can and EGR delete if possible. My D22 ZD30 Diesel Navara at 200K has minimal blowby, i must be doing something right😎

hello, can I install the catch can and delete the EGR?

Probably the best video on you tube.

If the inlet to catch can is at the bottom, does the oil build up and start boiling in the catch can? Something doesn't seem right to me

For gas engines, a lot of blow by in your intake with lower the effective octane in the combustion chamber.

Can I just vent the catch can to atmosphere instead of rerouting it to intake manifold ?

Is an oil catch can recommended for a Ford Ranger XLT bi-turbo (2019)?

good explanation

Very helpful and informative!! Your advice on this would be greatly appreciated. Out here in the US these smaller diesels are slowly starting to catch on. I picked up a GMC Canyon with the 2.8 Duramax diesel (apparently the same motor Mitsubishi uses in some of their pick-ups). I would like to add a catch can, the only problem is all catch cans seem to work half-ass at best. All the reviews and research I've done says you simply can't collect all the vaporized oil from the crankcase ventilation without a much longer refining process, and that vaporized oil will still collect past the catch can. What are your thoughts on this? is a catch can a cure all as far as preventing build up, or is it just enough to slow the inevitable process down?

Thank You, Ive built several gas turbo/SC gas engines but recently bought an EVEREST with the Raptor diesel Bi turbo engine. Its my first Diesel and Im trying to learn as much as I can about things like this. Have you worked on this engine, as Im trying to find a good catch can for it. Im not planning on doing anything special to it, just want to get some preventive features on it. Any advice would be really appreciated from anyone. I remember when I first started building a car for the track, ( I was still learning alot) I noticed a problem with the oil build up in the throttle body. I pulled the intercooler out and sure enough it had a decent amount of oil in it. I had no knowledge of catch cans at the time and used a water filter from an air compressor. It actually worked really good, then a guy asked me what the heck it was. He laughed and told they make actual catch cans. Anyway, I thought someone would get a laugh from that.

What if the turbo is damaged and throwing oils in to intercooler which eventually goes in to combustion chamber through intake manifold ?Turbo dies slow death and by the time you know enough oil is already on intake valve.

So what's worse, black, vegimite build up in your egr/manifold that gets cleaned out occasionally (probably more often than needed) or black, gritty, abrasive exhaust gasses being sucked into your engine because they are not being caught by the oil that is now in your catch can? I'm talking turbo diesel here.

problem for a manufacturer is that heat cycle of the engine removes moisture from the oil system - hence separating all the vapour would be trapped in the engine. Catch can can slow down fauling up of intake past egr input, but it’s on case by case.

Thats what you do. Cable tie it to the brake lines. Sweet. Thanks.

What is the make of the catch can you are installing in that Mitsi?
