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 RUclips. 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.
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.
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.
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
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.
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.
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.
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?
Have brought a catch can for my Ute with 27,000 on it. Was going to install it and EGR plate but have read not to do ANY EGR delete with it has a dpf. What’s your thoughts on this? Ide rather get rid of EGR crap if I can
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.
Question please... If deleting your EGR is illegal because of emission regulations, why isnt what you do" tuning out the EGR" illegal? You are effectively changing the emissions too right?
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.
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.
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 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?
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.
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?
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.
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.
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..
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?
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.
Are you saying that engineers who design engines, modern engines up to now that do not use OCC are mistaken? How do make up for parts that get lubricated by the oil spray introduced into the intake manifold?
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?
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?
Cheers, I know about runaway diesel engines. Nightmare. What happened to a friend, in his diesel XV, was that he braked approaching a junction, dipped the clutch and the revs went through the roof damaging the engine. Subaru dealership blamed him for changing down and overrevving the engine, but I find that difficult to believe.
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
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.
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.
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
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
It really depends on the engine but build up of soot contaminated oil around the valves will almost always have more of a detrimental effect on valve clearances and general wear and tear than reducing the amount of blow-by.
@@MRTPerformanceAustralia Recently did a complete intake clean on my 1kd with 400129km. Also did a partial blank on the egr with a 7mm plate..... Am thinking catch can also.
@@AndrewSparkfish I read somewhere that with the 1kd you shouldn't do the blanking or partial blanking Of egr as it also is connected to the waste gate of the turbo. Have you noticed any problems with lag ?
I have a 2L CRDI sportage, should I be looking out to buy one of these to keep my engine running healthier for a long time? It doesn't eat any oil across the year to be honest
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.
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
And that will also allow unfiltered air full of dust and other road debris into the engine when suction is present. Which is only a very small part of the time, but an open line to the crankcase is a great way to wear that engine out in no time.
General blow by pressurises the crank case, it’s one of the reasons old engines weep as bad as they do. I supposed if your pipe is like an inch long you might have a point.
All the old trucks I drive at work all have crank case venting to the atmosphere the pipe from the top of crank case down to just below the oil pan is plenty long enough to prevent any so called debris from going up it also it’s oily so it traps the dirt. The stock form of venting is simply emissions systems, vent to the air is the old way which works.
