- Here at MRT we talk a lot about the problems with soot buildup in modern engines. Particularly turbo diesels.
One of the comments that comes up quite often is "why don't you just fit a catch can", so today we take a look at the benefits of fitting a catch can to reduce oil ingestion and upper engine soot buildup.

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 TH-cam. 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 . 👍
Extremely well explained. Sounds like i need one for my 7.3 powerstroke.
Can’t get any better then that. Explained plan and simple for anyone to understand. Good work
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.
Mate another great educational vid. Amazing you can do all this in one take, shows your knowledge of these systems.
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.
it... catches oil
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 explanation and concisely presentation! Thanks for making this!
Great explanation, crystal clear!
Great pointers ,well done.
So good to listen to. Clear precise info well spoken word Many thanks
Thanks Brett
Very informative, now I know what I need on my KUN26R
Brilliant teacher indeed.
The best simplest explain action:-) thanks
Great video. It’s my first diesel so this is very helpful.
Great video, looking at this for my Mq Triton
Provent make a custom fitted one..
Autobarn sell them. Check out the website at Directionplus.com.au
Excellent video Brett! Same issues with older Tdi Land Rover engines
Will do a shout out on my channel soon!

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.
The best educational video about catch cans out there. 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.
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.
Excellent explanation, thank you. 👍
Wow! Great explanation. Well done.
Probably the best video on you tube.
Well explained, thanks !!
Great information 👍👌
Extremely helpful thank you
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
Awesome, loved it. Thankyou
Very informative!! Thank you.
Nice one thanks. If you haven't alredy, do one on fuel pre-filters please.
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😎
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?
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.
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?
Another great informative video. Thanks Brett.
Great video. Can you fit dual catch cans? Would that help or work?
Good information man
Thanks for explanation 👍
good explanation
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
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.
Some of that oil the catch can collects can be very dirty and even have some water.
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?
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.
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.
Does the sizes of inlet and outlet of catch can matters? My OCC inlet is 15mm with 10mm outlet.
Would this work on a 2.8 diesel 2016 GMC Canyon
Thanks, good info! 😎👍
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.
What model or type of catch can can I use for a 4m40
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.
Thanks Brett. Great information
Good video
Do I need an oil catch can for Subaru XV ‘19 ?
Thats what you do. Cable tie it to the brake lines. Sweet. Thanks.
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?
After watching your video I might install OCC on my 2017 Pajero/Montero sport A/T. Kindly advise. Thanks and more power.
What more advice do you need?
top notch video
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
Are the ProVent catch can better than the TerraTuff? I am thinking of getting one for my Mitsubishi Triton MR. Please, any advice?
Nice and clean coming out back to turbo would require a better oil separator ie Provent or Flashlube Pro.
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.
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?
Do I need a catch can for 2014 outlander Mitsubishi diesel
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.
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.
Can you figure out how to put one on a ram 2500 6.4 hemi , everyone says you can't.
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?
What catch can would you recommend for a LB7 2002 Duramax?
Provent 200
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
Is there any benefit on a Subaru diesel?
How did You bend that hoses?
Hello, Would you recommend an Oil Catch cabin for a Toyota Hilux Vigo 2009 model?
For gas engines, a lot of blow by in your intake with lower the effective octane in the combustion chamber.
Where tp buy thos catch can and hose for same engine. Though for pajero sport. Thanks
Thank you for the video. Do you have a catch can size you would recommend for a Chevy Colorado 2.8L duramax diesel?
No. There's none. Just get a standard one. All you need is 2 hoes and a few clamps. Easy installation.
Provent 200
Nice video Brett...that catch can looked similar to a HPD, which just use a small bit of stainless guaze.. pretty useless... the best CC are the ones with a proper filter membrane like a Mann & Hummel, pro vent etc. and with a proper filter membrane the size of the filter and CC is irrelevant provided their drained off properly.
@@BeardedBavarianBiker. they all look similiar but certainly don't perform the same...
Is it okay to vent the occ outlet to air?not back to turbo inlet?will it cause issues?
I have a series 5 L200 Barberian. do you sell the Catch can kits ???
thoughts about catch can with vent out setup?
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..
Do you ship to USA?
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
I did not understand shit. But I can safely say that this dude knows his shit to able to articulate such in-depth technical info from the top of his head!! Much respect.
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
What's a good brand of occ for 4n15 triton?
How big of a catch can did you put in this engine?
Is an oil catch can recommended for a Ford Ranger XLT bi-turbo (2019)?
I would put one on it...
Hello I have a Cadillac xts vsport 33k what catch can is best for this vehicle?
BIG..
Do you ship to the Philippines?
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?
Thanks 👏👏👏
What is the make of the catch can you are installing in that Mitsi?
its on top of the can.!!!.bigger the better.with a filter,breather.regardless of make,all do the same job..
Good video, thank you
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.
How does this fitment and tune affect the new car warranty?
