I suspect you are already on the road so it’s probably a moot point, but I suggest performing a simple compression test. If the engine is dusted, you should pick it up with that test. If the compression is ok, it should last the distance on your trip. While I understand you’re logic of just heading out on the trip now, if it is dusted I would rather have it sorted where you are in a familiar location with a roof over your head. Also, dust getting past the filter should nuke both turbos. One was spotless, one was dirty. That just does not make sense to me. I suggest a leak exists somewhere else post air filter. If that is the case and it’s not identified or rectified, you will have a repeat incident at some stage in the future. Thanks for sharing your experience and I trust you can enjoy your long planned holiday with minimal apprehension. Go well mate.
I have to say, I agree. I’m certainly no expert, but my guess is that unfiltered air is entering the system after the vehicle’s air filter but before the damaged turbo’s inlet. Otherwise, surely both turbos would experience the same damage.
Great Video as usual Nathan, but I also find it strange how one turbo can be perfect and the other affected. I note you have previously "tuned" the 200. That seems to be the most common single factor to problems. I think the 200 just does not like tuning. Good luck for your trip.
I agree. He did say he had a hose unplugged on that side & this may well have been where the dust entered. Another thing here is that is is more common for the passenger side turbo to go first & get dusted as the air flow configuration means that the air has to do a 150+degree turn to enter the driver side turbo so dust particles are more likely to fly past this intersection & hit the second turbo. I had a passenger side turbo issue with a 200 series, I believe it had been either dusted, flogged or both, anyhow it did use a bit of oil, then a fair bit of oil, I added a catch can at this stage knowing I had problems & then I got the check engine lights & limp mode, I reset it & it old go ok for some time & then got more frequent. By this time I had figured out (sort of) the problem, which was a sticky actuator issue running the amps up to 5-6amps would throw a code of turbo or actuator problem, turns out it was burning & blowing so much oil through the passenger turbo, that it was carboning up the variable vanes & with a little CRC and a quick fiddle it was free again, but I installed a new turbo and injectors anyhow at the time. So I would also suggest to maybe check how much, if any blow by u have by just taking off the oil cap while it is running, it should not be too much if all is well.
I worked on the Dampier to Bunbury gas line in 2009-10 as the LV mechanic , we had a few 200s on the job . At the start of the project near Dampier we noticed the 200s was pulling dust through the filter (genuine ,no snorkel ) where the 79's didn't . we took pictures and sent them to Toyota . response was that the dust particles were smaller than the EGR particles so they couldn't see an issue ! 6 months later down near Geraldton we had a really fine dust like cement powder . 2 dusted 200's in Geraldton Toyota . They were going to bill us for the engines , until we sent them the emails about the EGR particles . The whole intake system on one car was bagged and sent to Japan for examination . It's sad after 12 years this is still an issue .
Mate one tip I can give you, irrespective of what air box you are running, generously coat your air filters outer rubber sealing surface with rubber grease this works wonders and common practice in my earthmoving workshop. It is unlikely the dust is passing through the filter media and more likely a sealing issue, dust sticks to grease and grease promotes sealing against the air box. Anyway Good video mate will tune in again cheers
Check your turbo ducting aswell everyone gets caught up on the airbox thinking it’s the issue all the time. Only to have the issue happen again. The intake ductwork that runs down each side of the engine can and does suck dust on some of the 1vds. Another problem area they had was the intake duct the splits into the two individual turbo ducts under the intercooler. That piece got recalled. Hope this helps. I’ve worked on hundreds and thousands of these 1vd’s and ive seen cruisers with custom airbox’s get dusted all because of leaks in the ductwork.
Absolutely spot on my friend. Pre-cleaners make the situation worse as it can increase the vacuum on the ductwork. Other things include running with a clogged air filter which also increases the vacuum hence the possibility of leaks through the air cleaner seal and the ducting. In this case if the air cleaner were at fault, both turbo's would be affected. This indicates a leak to the drivers side turbo between the intercooler and the turbo.
@@johnpickering5289 I was thinking the same thing, I know very little about this engine but if the dust was getting past the filter in the airbox why arent both the turbos in the same condition? Made me think the dust was getting in on one side only. I get why one side gets an oiling from the PCV as its plumbed to one side.
@@johnpickering5289 you are onto it John. Snorkels and pre cleaners can restrict airflow and along with dirty or restricted air filter element puts the sealing of the ducting to the turbos under stress. Result is dirty air pulled into either or both turbo/s. I don’t know if this vehicle has been but chipping an engine to increase power proportionately increases the air required exacerbating any leakage.
When I was an diesel apprentice we had this old timer come in now and then to help out. Old quote what he didn’t know ,wasn’t worth knowing, we had an old 555cummins in and the customer needed it to last another 6mth while his new truck was being built. The engines wasn’t happy, excessive blow by, aero start was its favourite inhalant. Old Jack has a look , a listen, a fiddle and goes back to his panel van and pulls out a can of Ajax. Ajax back then was a powered in a foiled cardboard can. He removes the intake pipe and get me to start it up. While revving the engine he takes a tea spoon of Ajax and lets the air rushing around it suck in the Ajax. It actually gave the old engine it’s ,compression back and it’s aero start addiction was a thing of the past. The Ajax was like a re-ring. If I didn’t see it with my own eyes I would have dismissed it as a myth.
I would of thought if it was a problem through the main air intake then both turbos would be dusted. However only 1 has a problem. That more likely suggests a loose inlet hose/pipe after the air flow splits in two to each turbo.
My comments for what they are worth. I have a 200 series 2012 completely unmodified bought from new. The only part other than regulator maintenance I have had to replace is the alternator. I suppose most problems people have with the see vehicle is because of the modifications they are making. Keep the vehicle standard and avoid all these issues. The vehicle is extremely capable it doesn’t need anything!!!
Maybe, however I would disagree that a standard 200 would be able to tackle and successful drive out of the terrain I use it for. Don't get me wrong, they are awesome vehicle stock, however like everything there are limitations. 👍 Here's hoping yours continues flawlessly for many adventures to come 🤞
Very familiar story. We left Perth on our 12 month lap at the start of Feb this year. Got 20kms out of Ceduna when the vanes seized in my drivers side turbo. Nursed it in to town and had to wait 13 days for parts and fitting. Had a few more dramas with the car over our trip but well worth it for the whole experience. Great vid and thanks for sharing 👍
Sorry to hear that mate, I know the feeling! Interesting to hear that most peoples experiences if all in the drivers side turbo... Well either way, I'm glad to back on the road now and hopefully my cruiser follow's in yours footsteps and is problem free for at least the next year 🤞
More likely to be just a faulty actuator or possibly the variable vanes gunked up with exhaust soot . That " dusted " turbo didn't appear to be very damaged . If the shaft isn't wobbling or the fins damaged it would still work . I believe that the actuators can be purchased separately now .
Yes, I also noticed this, the turbo vanes still appeared to look ok, no signs of wear or rounding of the corners from what I could see. Nathan didn't really go into examining the turbo condition other than mention the scarring of the intake.
Years ago I had trouble with a TD5 Discovery and a TD4 Defender. Factory rubber turbo hoses kept internally delaminating restricting airflow and limp mode. Once I upgraded to after market silicon hoses and better clamps the problem never returned.
Nathan, I had to replace both IHI turbos on my old 2012 200series at 110,000km. Codes were P004B (left turbo) and P0046 (right turbo) and the problem was it would go into limp mode whenever I towed the caravan up a decent hill. No evidence of dusting. Turbo shop suggested the issue might have been the vanes getting stiff, which increases the current draw of the stepper motor which triggers the code. They had brand new turbos on the shelf because they replace a few. Just 200series life. I had had enough so now touring with a VDJ78 Troopy which has a single Garrett turbo. I know the guy who bought my old car and it has given him no trouble over the past 3 years since the repair. Yours should be fine now, but my opinion is the IHI turbos are not the best. Enjoy your lap of the country!
If you pull your intercooler off and check I think that you will see lots of the dust has been cought in there, the oil from crankcase breathers coat inside the cooler which then catches the dust. Wipe around the intake manifold (after the intercooler) with a clean cloth to see how much has gotten through. You may be surprised.
In the 4 years from new I had nothing but issues with my 200 series. It just wasn't reliable at all. I sold mine when I realised dust was getting past my filter. I went to a Y62 Patrol and it's been awesome. Average the same fuel usage and cheaper overall and zero issues in my first 2 years. All the best mate, I hope you get it all sorted.
I hear you mate, there have been times recently where I have thought the same. The amount of time and money that has been spent on this vehicle is hard to come to comes with. All part of the passion with this type of industry I guess...
What a bloody nightmare Nathan. I love my 200 but was aware of the Airbox issue before I bought mine. While checking out potential vehicles in 2018 before I settled for the one I bought I looked at an 18 month old 200 VX at my local TOYOTA USED VEHICLE dealership. Took it for a run and it was less than impressive. Brakes and power didn’t feel right for a rig that should have felt near new. Parked up the truck on the way back to the dealership and upon closer inspection there was red dust in every crevice that was missed to clean. It had been a dust pig in its past life and I suspect western Qld and NSW looking at the log books. Maybe a rental or ex gov perhaps. Popped the airbox, hand up inside intake and there it was. Hand absolutely caked in red dust that had entered the engine. I showed the Toyota dealership and their response “don’t worry about it mate it’s still got warranty on it”. Thanks but no thanks!! The first mod I Did after suspension on the rig I bought was to fit a Radius airbox made locally here in brisbane Capalaba. I also fitted at a later date a K&N. I’ve just complete a 7000 km trip for my long service around west and far Nth qld towing an Austrack 15 and the cruiser performed seamlessly (did I mention I love my 200). I did a white cloth check on the intake when I got back and relieved it was spotless. Relieved?!? Well the thing is just doing it’s job after all. I am really surprised Toyota missed this issue. Whatever aftermarket airbox you decide on I think it’s a very wise move and investment especially if you put your feet into some dust. As to why only one turbo had dust in it that may be a question for Toyota themselves. A bit strange. Maybe there is another issue there. Now, most importantly, enjoy your trip and safe travels through this amazing country of ours 🇦🇺
Sorry to hear about your troubles with the car, I’ve got a 2004 100 series and see no reason to update to the new 300 or the 200 before it. I’m going to build a 105 into a fun truck for half the cost of a new LandCruiser. The two cars will cover everything I will want to do and I have great confidence in there capabilities and toughness.
I dont agree it is a dusting issue, the VNT Turbo's are prone to fail on all Toyota models, not just LC200. Disconnect the actuator on both the old turbos and you will find that drivers hand side turbo is siezed or very stiff, that is why it failed.
I note your comments regarding dust ingestion in 200 series. The Donaldson precleaner is a big part of your problem. They used to be used on Farm 🚜 tractors years ago...not anymore. They allow dirt to enter but trap most of the dust. The newer Vortex precleaners are automatically ejecting 98% of particles....I wish you luck with "The Big Loop " The 200 series will get you there.
Hey Nathan Same thing happened to us when we bought our landcruiser from a Toyota dealer in Perth. The vehicle was originally from Melbourne and it got sent for sale to perth. We ended up flying to Perth to drive the cruiser home to Melbourne. During the drive, somewhat 200 kms out of Perth not too far from Avon caller Toyota our car decides to go into limp mode. No scanguage, no ultraguage and no idea. We managed to get codes cleared and drove for 5 minutes before car was in limp mode again . We weren’t driving this car home. We later had the car towed to midland Toyota and they where awesome. The fixed the car and flew us home to Melbourne. It was a journey I wanted to do first time in the cruiser. I was shattered. Enjoy your trip and your truck will be right
A quality aftermarket airbox should be the FIRST mod for any owner with the v8 diesel. This happens so often it baffles me why people don't know about it or do it.
Thanks Nathan - as always - for your thorough, intelligent and measured description and analysis. We all learn enormously from your superb videos, and I especially appreciate them as an overlanding LC200 series owner. I also have a Donaldson pre-filter and have recently ordered the new Donaldson XLC200K airbox. I wonder how much of the problem might have been "seeded" by the previous owner - would the pitting in the turbo possibly suggest a very "old" issue? There is absolutely no need to apologise for any of your videos. Every one of them is informative and engaging. Can't wait to see your travels and adventures with the family on the big lap. Enjoy every moment!
GSL fab makes a 200 series air box that you can see what it looks like on the clean side of the filter before it goes into the engine, stainless steel with clear Perspex inspection lid and triple crush seal gruve for the square filter . it's made so that any fine particles that might get through the element you will see on the inside of the clear Perspex , if it's clean you know that you are still fine to go on, but if you start to see any residue it's time for you to do maintenance.
Sorry to hear the news Nathan. It would have been a horrible time for you being away and not being able to do all that much. Yes, things could have been worse but at lest you now have a plan moving forward. Stay safe mate and I'm sure a lot of us are looking forward to the van reveal. Cheers,
It wasn't a whole lot of fun, but we are back on the road now an looking forward to what is to come! The reveal is all uploaded and set for tomorrow morning! Can't wait to show everyone. Hopefully we'll be able to catch up somewhere on the road now that we have started our big lap 🤞
I'm sorry to hear about the dusting. But in my opinion, I don't think it was an air box issue. If it was, it would have dusted both turbo's. I'm thinking your problem might have been in the intake pipe between the air box and driver side turbo. The clamp might not have been tight enough and let some dust in. Causing one turbo to be damaged and not the other. On my 79 I've replaced the std air box with a Patrol Docta unit. Great fit and works great. Coupled with that, I'm running the Uni filter that I clean every 2500km. But every time I'm under the truck, I look at those plastic pipes and hose clamps and think....man those things are flimsy! Those pipes could flex and move just as much as the factory airbox. The problem is, we never inspect those pipes and would never know if they let dust in...! 🤔
I tend to agree with you. If it was the airbox then your hoses to the engine would be packed with dust if the turbo is anything to go by and it would be both not just one. That much dust would also most likely compromise your MAF sensor. Is it a possibility that the little hose that was disconnected could have been the culprit since you had a vacuum and it actually sucked the dust in there over thousands of k's?
Good video, it’s great to see some honest owners breaking down the myth and mystique surrounding Toyota Engineering. They make great vehicles, but they do have issues with design and application like all manufacturers.
Haha, it sure was! Definitely had some up sides though, like exploring the coastline and chasing waterfalls. Here's hoping for a trouble free trip here on in 🤞
When you do river crossings you need to understand a bit of physics. Those Turbo Electric Actuators get very hot. when you dip them all of a sudden into cold water they suck in water like a Sponge. Then the ticking time Bomb starts. Are we learning yet?
Hi mate, i have a 79 dual cab a 300 as a company car… owned several v8 70s, 200s, as well as 6 cyl 75s. Got a nice fj 45 in the shed. Recently been on a 3 million acre cattle stn with v8 utes. All have the after market air filter box as the plastic ones deform in heat and cold and under load.
Thanks nathan. Sorry to hear of your bad luck, but your excellent explanation is sure to help someone else prevent this happening to them. Keep the excellent content coming. I do hope you complete your trip with zero issues and then rebuilld or new engine.
What a tale! When I got my 200 series with 100k on the clock. I was shocked at the amount of dust present downstream of the air filter especially on the passenger side turbo intake. I boroscoped the turbos, they looked ok, no signs of rounding or damage to the turbo vanes. I immediately bought a Moonlight Air Box which works well. My injector values are good but I am concerned if some damage has already been done though there are currently no signs of damage, e.g. excessive oil consumption, excessive crankcase pressure, excessive oil dropout in the catch can.. A great engine let down by a shithouse air box.
The stock Toyota airbox is fine if you know how to correctly install the stock paper air filter. Those oiled Unifilters soon lose their surface oil tackyness in dusty conditions they rely on to work & then pass plenty of dust through their open cell foam. Fit one of those Terrain Tamer airbox seal kits & you'll be good, if you pay attention to the paper filter install & don't roll the seal when fitting the lid. Unifilters also coat the MAF sensor in oil film.
@@dustyfarmer my two bobs worth. I had a new 2002 Jackaroo and was headed into the Simpson, so I ordered a unifilter oiled air filter. We left on the original paper element, I was religiously checking air box exit (intake) monitoring for dust intake. (Twas my first diesel engine, hence over conscientious). To my delight it was always clean but once I noticed dust was getting past the original paper element, out it went and in with unifilter element. By days end oily dust particles lined my air intake. I was bewildered. By day two it was truly noticeable. That's bullshit I says. I gave the original paper element the best clean I could and refitted it. As soon as I could I got a genuine replacement paper filter and all was good. On returning home, I took the unifilter back to ARB supplier whom sent it off for analysis. To my horror, it was determined not to be faulty and no refund was forthcoming. One bitten, twice shy. I have run genuine filters eversince in everything but a 76 series I was silly enough to buy. Dust got by no matter what filter I used, so I used to lighty brush & vacuum the S/S gause clean just prior to sensor. Always a concern. I was never truly happy with the 76 as a vehicle, it is so over rated, so sold it off went back to Jackaroo's in preference, so under rated in comparison. Now in a Y61 Patrol running genuine paper filters. You are right, that oily dust would have to coat the MAF sensor. You must monitor intakes beyond filter closely, doing that avoids costly repairs Nathan experienced.
Hey Ian(?). On the Simpson trip, how often were you checking the air box exit please mate? Every night after a days run or sooner? Just keen to know so I can start doing that too on any dusty runs I do. Seems like a simple but practical thing to do 😎
@@PaulMotu hi Paul, as I mentioned, it was our first diesel so I was very conscientious of dust bypassing filter creating issues. What I neglected to mention (once I re-read my comment) was I was travelling in convoy, hence consistently drafting dusty air. To answer your query, I checked air box, filter, and intake nightly. Pleased I did, as I got ahold of the poor quality of the non genuine filter quickly. NB. If travelling solo continuously drafting clean air nightly would be overkill possibly but I was in convoy. As mentioned I now drive a Patrol and religiously utilise genuine filters that are oil impregnated paper. They are truly good, but I had an offer to try a non genuine product. Noticed immediately it was just paper without oil impregnation. Was it effective, I'd have to say yes but I don't believe it captured the finer dust particles the original oil impregnated paper does, so back to originals only. Now days, if I'm in convoy on really dusty terrain I fit a snorkel sock. I carry two snorkel socks as they can restrict / block air flow quickly, hence mid trip dirty one off, spare clean one on. These capture a bulk of the dust, nightly wash, re-lube, refit if required. If not required I immediately place the cleaned re-lubed socks in snap seal sandwich bags ready to use when required. Hope this clarifies your query.
Send an oil sample for analysis and it will help to determine whether cylinder wall material has scraped off into the oil, and how much dirt is in there. Send those two turbos off to a turbo specialist and have them upgraded for next time....
That sucks man, feel for ya. For that reason this is why I got a Y62 Patrol. Less things to go wrong with them and parts are alot cheaper than Diesel engines. Big Oz Explorers have been lapping for 2 years in there Patrol and had no issues. Good luck on your lap, I'll be watching 👍
Did you do a compression test? I mean, if the values are all still fine and they're all close to each other, than chances are the motor is fine. On top of that, the damage to the turbos could have been before the installation of the uni filter. Though, the factory airbox is rubbish. The most likely culprit of those turbos will be the motors I reckon. They won't be moving the vanes.
Absolutely, that is definitely the silver lining. Couldn't imagine the extra stars having to deal with all this in a remote section of the Nullarbor with the family in tow...
I have used a Unifilter since owning the car and since using it have never had a dust issue not even that fine dust you see in the lid when in the sunlight that you can wipe off with your finger so I am surprised you have had this dust issue. Usually it is the passenger side turbo that fails when it comes to dust.
Yes, I had the same experience in relation to the visual dust on the airbox... Maybe it was from before I purchased the vehicle, maybe I just missed it... either way, here's hoping the new turbos get me a whole lot further than the old ones 🤞
@@XploringOz Thanks, besides that bet you are excited for your trip. We are on the road most of the time and it is such a great country to explore. Are you going across first to the east ?
Very sorry to hear this . We have ordered a 300 which has the same problem so looking aftermarket to. Hopefully you will be fine now and just enjoy your trip
Yeah I would be tracking down the problem by removing the air filter first and inspecting the air intake for dust particles from there forward, keep going until you find the culprit . Good luck!
Just a small issue that does not impact on your video main theme. The exhaust enters the turbo via the entry on the outside of the spiral of the exhaust housing, the exhaust exits via the central outlet. It is the exact opposite of the gas flow of the input.
I think Ian Dibley has a good point as only one turbo failed when all the filtered air comes in one main tube then splits evenly. A really close look at the pitting shows pits much bigger than dust particles, more like the size of sand impacts. There looks to be more pitting on one area also. Is it possible pitting happened some time ago and the turbo survived. Recent extra engine load with the new van caused this sticky turbo vane from poor oil circulation. Mobil make a specific Turbine Oil DTE series for high rev spinning engines. Why does Toyota lubricate diesel turbos with 15W-40 when DTE is available
Pt 2. They wont/dont run 200s as this issue is too severe. Prefering the prados as a station wagon. This is up in Newman. Even their workshop has a spare v8 rebuilt waiting. So, (i know you know), get the steel/aluminium box fitted asap. Pre cleaner (which i note you have) and once sorted should be fine. Toyota need their arse kicking frankly. (Cant tell u who owns the station but they buy plenty of toyotas) Me? Insold my 200 and went back to the 79. 300? Nice company car but id never own one.
I would keep an eye on oil usage. If it's getting excessive; it may indicate oil rings and cylinders have premature damage. Also bearing may have wear too (watch your oil pressure) It should be ok for your trip but keep it topped up.
Hey Nathan, even in such adversity you remain professional and objective, as always! And sooo cool I have to say! Highly admirable! Respect! Wishing you all the best for your next big adventure - I look forward to the videos!
I wish to add Mobil Turbine Oil thru the diesel turbos should be a separate circulation system and could be by a dual purpose power steering pump. Turbine oil is about half viscosity of 5W-30 at 100deg C and similar to Power steering oil which itself is close to hydraulic pump oil. These 5 cSt @ 100deg C viscosity oils provide immediate turbo lubrication when engine is cool and designed for 600 deg C turbo heat. The engine oil 5W-30 in DPF Toyota 1VD and 15W-40 for pre-DPF diesels is designed for reciprocating petrol & diesel engines operating up to 90deg C, NOT for turbos spinning at 80,000 rpm
So sorry to hear what happened to your landcruiser mate. I've watched all your videos and I know that you really look after your car. This turbo issue was reason l bought the y62 instead of the Landcruiser. Looking forward to your future videos.
your engine is fine, dusted engines use oil like mad I know this as I used to work at Cummins you have not told us if the actuator arms are free, i sprayed my Disco three turbo arm with a mix of kero and 2 stroke oil thru a long garden spray wand as they cannot be reach by hand, yes clean air is all the engine must have, is your snorkel pointing back good luck
Geez after all those other tweaks that you have undertaken and the dust still got in. You have convinced me to change out my airbox for an aftermarket unit. Our cruiser only has 40k on it so I would like to see a few hundred thousand more without similar failures!
I use a K&N oiled air filter on my R51 and the airbox is spotless even after long outback drives. They do need regular cleaning and reoiling but I have used these since my motocross days in the 80's and they are great if properly maintained.
Check out the exhaust turbine and see if there is anything loose. Variable geometry has moving parts. It will not go to zero boost over night from wearing out
Hope your holiday is going well. Mate I watched you video in your turbo issue. Something to consider mate would be to check the induction plumbing to that particular turbo. An air filter issue would usually represent its self equally in each turbo. Again hope your trip is excellent. Cheers
What was the final repair bill May I ask? Bloody expensive hobby these cruisers that seem to be rife with badly engineered issues and full of probs if used more than a soccer/school drop off! Also Nathan what profession are you in?
Water ingress to the Electric Actuator. The Turbo's are worn but fine. CCT Stage 1 are only $2,200 for the pair. #8 Cylinder will already be down Compression. So start prepping for an Engine rebuild next. The reason #8 is the same reason why one turbo is fine and the other is worn. They duct all the PCV air into one turbo. You guess which one..lol If you could see the dust in real time you will find the most of those heavier particles end up getting swallowed by #8 cyl
Hey mate, not discrediting your knowledge, but I don't think it's right to diagnose and predict repairs and damage without first inspecting the vehicle.
Wow. So sorry you are another 200 series owner with the dusting issue. Terrain Tamer have a fix. Check out their filter that has a SS support that prevents the air box from distorting under pressure/vacuum. It may keep your 200 safe before you get your new air box. I hope all goes well from here o . I do still love my twin cab 80 1HDT cooled boosted and on D-Gas and only 240,000ks.
Cheers mate, yes this was another consideration as a temporary fix. I'm lucky enough to have the new box now, hopefully only a couple more days before it's fitted
I feel your pain but I have no problem with my stranded air bocks the trick is toyota gen filter and some vass🙃 make sure it's secured and all good. The dusting was from blown off the map tube Clean it new tube and super glue. Unfortunately you have dusted 4 pots when your thinking about injectors do a pressure test on all pots
Wow what a roller coaster of trouble and mental stress. A few things to think about. Why is the left turbo so clean in comparison to the right? Was the left turbo replaced before you owned the vehicle, or was the dusty air introduced after the air filter after the split to the turbo inputs? Was dust on the input to the intercooler only on the feed from the right hand side turbo? If there was no dust here then scenario one (left turbo replaced before) may be the reason.
Hi Nathan Very sorry to hear about this misshape! And that you have to experience it just in front of your big trip. Having looked at your vid carefully and read all commences till now, but I not understand several things there. My I not familiar enough with this Toyota V8 engine. I deal with dusted diesel engines in our customers mining machines and they show first high oil consumption and not total boost pressure loss power loss and never a limp mode. When talking oil consumption I mean 20 ltr in 20 operation hour on full load. When this engines dusted the turbo charger blades are visible worn and the engine oil is much dust contaminated. Boost pressure on a regulated turbo charger is not out to zero in a short time. Would be interesting to know later what really caused the one turbo failure and how much it will cost you to renew the two cores on the units to get 2 pc 100% recon units. Are you then going to put them up for sale? Please keep us updated, but now take your time and focus on your new van to get ready, enough mod work to do I belief. Keep the sunny side up Cheers
Crazy mate…what a story!!! I’ll send some photos thru of my turbos, similar finding to you…crazy dust evidence on drivers side, passengers side clean but compressor fins showing rounding and damage from debris impact (dust or oil vapor).
Thanks Nathan for the info and your experience. I check my filter regularly as i live in the bush. I think i will replace the air box before my next big trip next year. Hope all goes well with your trip. Bravo from Victoria Australia
Mate I can recommend PSICO in Bundaberg QLD - if you haven't already made a choice. Their gear is first class and well under the price of other brands. Maybe worth checking out. I have their custom box and filters and it's going great !!
Not likely as the oil and dust act like grinding paste. Toyota have reluctantly replaced engines under warranty due to dusting. Originally they blamed the driver or said it was normal...a $45k job apparently.
#1 thing for me is why & how. There is obviously a issue somewhere that is letting in unfiltered air into the system. For the money you pay for a 200 you would think that Toyota would have an impeccable engine filtration system. The Uni filter is a bit rubbish good for motor bikes or race cars. I hope the engine hangs together for you. Thanks for sharing 👍🏻👍🏻🙃🙃
I've only just discovered your channel. As I am about to buy a 200, I started to do some research on any possible problems. Hence discovering your very informative channel. One thing I am VERY confused about is why only one turbo dusted? Doesn't all the air come from one source? If one is dusted, surely BOTH should be dusted at the same time? Is there a leak in the pipework to that turbo? It just does NOT make sense that only one is affected. Can you enlighten me please.
🤦♂️. 1 air box feeding 2 turbos but only one has evidence of dusting? No split in tubing supplying the turbos for the air box. I assume they’re supplied independently from the air box?
You are a patient man....I would have completely lost my sh*t and I have had 3 X 200 series but was lucky that nothing failed. Toyota have a reputation that is probably ill deserved when you dig deeper behind the hype. BMW had issues with a couple of their V8 engines back in the day and they stepped up and took care of their customers. I don't ever recall hearing Toyota doing the same. Good luck with your adventure and hopefully it gets you all the way around.
Yeah I hear you there mate! it is disappointing that Toyota haven't taken some sort of responsibility or even rectified the issue in the newer models! Like you said though, they are becoming know for it and this will hurt their rep in time
Chances of both turbos failing at the same time, almost impossible however I suspect actuator damage to one turbo. If you have not already thrown them out it may be worth while to get the turbos bench tested independently if they are ok keep them as spares.
I still have them, however not with me at present. I would be interested to test them, but they are visually damaged. The turbines are coated in dust and almost look like they are pitted from constant debris
Ah what a bummer of a trip Nathan sorry to hear that. Hope the LC holds up for your trip. If you come by Melbourne again and ever need a hand hit me up.
I did the turbo going up Bogong High Plains Road in Vic. I know all about limp mode. In my research I found that a lot of the major faults in the D4CB engine are caused by leaking injector seat washers. Apparently they should be cleaned and machined flat every 10 000 kms.
Sorry to hear that mate. I was in that area a few weeks back and know how steep some of those roads are! Interesting! I'm guessing a proper leak down test would determine exactly where the loss of compression is coming from. Have you done this clean/machine process since? Any findings from it?
@XploringOz thank you! So I got towed to Bright and I asked them to replace the washers. Don't remember if they noticed anything there but the turbine was pretty mangled and i was lucky that remnants didn't go into the engine. I'm due to have them seen to again in another 60 000 kms. Sorry I can't be more technical seeing I'm a female 😉 have fun exploring 👌
You could do a compression test to check the current state of the engine and maybe it would boost your confidence or tell you that you have a bigger problem looming.
Nathan your knowledge on the Landcruiser 200 series seems to be epic, some advice please. I am planning a long overland trip in South Africa, my Landcruiser 200 is a 2015 model and have done about 220 000 km with a full service history at Toyota and not a days problem, love my vehicle. Do you think it's time to trade in or should I not be to concerned with the mileage. I must admit I am not a fan of the engine in the 300 series, would love any comments
Hi Nathan, well explained and narrated, albeit not an ideal scenario just before a big trip. Do you (or anyone else out there) know if Prado’s with the 1GD are susceptible to the same issues. Everything I’ve read is about the 200 or 70 series Hopefully you will be on your way and all these troubles behind you Cheers
Unlucky mate and very unfortunate timing with your big lap of OZ. Don't let it get in the way of your big trip around this amazing country of ours. If I was to give you any advice before your trip, it would be to perhaps to get a compression test done on your engine just for peace of mind at minimal cost. Other than that, it's a cruiser mate, drive it and take care of any problems as they arise👍
Thanks Tom. I will make sure to have a beer on you when I can finally relax when I'm back on the road! Hopefully we'll be able to catch up soon when I'm over your way 🤞
Bloody hell Nathan what a horror story, a little funny only dust in the one turbo may indicate the pipe to turbo I believe is has an O ring wondering if the dust leak is near to damaged turbo. I think getting a compression test will answer some questions ,if the compression was higher on the side the turbo OK compared to damaged turbo side it might rule out the airbox/ filter, the compression would give a reasonable idea of the engines health. Like yourself I have hanging out for the Donaldson unit & it certainly looks promising I will have one in about 3 weeks .Best of luck with things you certainly have been though the ringer.
Great story pity the way you’ve had to do the fix. I have been keeping eye out on the new Donaldson filter lately so thinking 15% off this Black Friday cyber Monday weekend I’ll be placing a pre-order.
Funnily enough mate, Western Filters have removed the Powercore from their website, just in time for Black Friday sales. Let me know if you locate one with 15% off from them.
Mate, what a mission. I bet you considered buying another vehicle while you were in Victoria. About that dirty fuel. Can you be more specific where you may have gotten it? Do you think it was mainly water or just crud from the bottom of the garage tank? That's always one of my concerns when going on a trip.
Yeah mate, for sure. I thought about a lot of things 😆 🤦♂️ I'm pretty sure the dirty fuel was from a service station in Narrogin, WA as this was the last place I filled up both times... I think it was just dirt from the tank over water. Definitely pays to keep a couple of spares on hand though
Nightmare. On my new 76, I've gone with a Donaldson pre-filter (after watching your videos) and a Moonlight Stainless Airbox. Seems good so far, might be worth looking into ....
Hey mate, I haven't heard the D4D engines suffering from this issue nearly as much as the VDJ's. It wouldn't hurt to prevent dust going into the airbox though, just have to make sure you get the correct size so not to restrict the airflow under acceleration.
I don’t see the logical link between airbox dust performance and only one of the turbos suffering from signs of dust damage. If the airbox was at fault, one side would not be clean. Did you or your mechanic check for for any cracks or air leaks on the pre-turbo intake? Particularly the side that failed? You should perform a smoke test on the pre-turbo inlet and ensure there are no leaks before you potentially munch another expensive turbo.
I suspect you are already on the road so it’s probably a moot point, but I suggest performing a simple compression test. If the engine is dusted, you should pick it up with that test. If the compression is ok, it should last the distance on your trip. While I understand you’re logic of just heading out on the trip now, if it is dusted I would rather have it sorted where you are in a familiar location with a roof over your head. Also, dust getting past the filter should nuke both turbos. One was spotless, one was dirty. That just does not make sense to me. I suggest a leak exists somewhere else post air filter. If that is the case and it’s not identified or rectified, you will have a repeat incident at some stage in the future. Thanks for sharing your experience and I trust you can enjoy your long planned holiday with minimal apprehension. Go well mate.
Was thinking the same. cheers
I have to say, I agree. I’m certainly no expert, but my guess is that unfiltered air is entering the system after the vehicle’s air filter but before the damaged turbo’s inlet. Otherwise, surely both turbos would experience the same damage.
Great Video as usual Nathan, but I also find it strange how one turbo can be perfect and the other affected.
I note you have previously "tuned" the 200. That seems to be the most common single factor to problems. I think the 200 just does not like tuning.
Good luck for your trip.
He is a bit of a drama queen with this this, one turbo failed for an unknown reason and he is already suspecting dusted engine.
I agree. He did say he had a hose unplugged on that side & this may well have been where the dust entered.
Another thing here is that is is more common for the passenger side turbo to go first & get dusted as the air flow configuration means that the air has to do a 150+degree turn to enter the driver side turbo so dust particles are more likely to fly past this intersection & hit the second turbo.
I had a passenger side turbo issue with a 200 series, I believe it had been either dusted, flogged or both, anyhow it did use a bit of oil, then a fair bit of oil, I added a catch can at this stage knowing I had problems & then I got the check engine lights & limp mode, I reset it & it old go ok for some time & then got more frequent. By this time I had figured out (sort of) the problem, which was a sticky actuator issue running the amps up to 5-6amps would throw a code of turbo or actuator problem, turns out it was burning & blowing so much oil through the passenger turbo, that it was carboning up the variable vanes & with a little CRC and a quick fiddle it was free again, but I installed a new turbo and injectors anyhow at the time. So I would also suggest to maybe check how much, if any blow by u have by just taking off the oil cap while it is running, it should not be too much if all is well.
I worked on the Dampier to Bunbury gas line in 2009-10 as the LV mechanic , we had a few 200s on the job . At the start of the project near Dampier we noticed the 200s was pulling dust through the filter (genuine ,no snorkel ) where the 79's didn't . we took pictures and sent them to Toyota . response was that the dust particles were smaller than the EGR particles so they couldn't see an issue ! 6 months later down near Geraldton we had a really fine dust like cement powder . 2 dusted 200's in Geraldton Toyota . They were going to bill us for the engines , until we sent them the emails about the EGR particles . The whole intake system on one car was bagged and sent to Japan for examination . It's sad after 12 years this is still an issue .
Mate one tip I can give you, irrespective of what air box you are running, generously coat your air filters outer rubber sealing surface with rubber grease this works wonders and common practice in my earthmoving workshop. It is unlikely the dust is passing through the filter media and more likely a sealing issue, dust sticks to grease and grease promotes sealing against the air box. Anyway Good video mate will tune in again cheers
Check your turbo ducting aswell everyone gets caught up on the airbox thinking it’s the issue all the time. Only to have the issue happen again. The intake ductwork that runs down each side of the engine can and does suck dust on some of the 1vds. Another problem area they had was the intake duct the splits into the two individual turbo ducts under the intercooler. That piece got recalled. Hope this helps. I’ve worked on hundreds and thousands of these 1vd’s and ive seen cruisers with custom airbox’s get dusted all because of leaks in the ductwork.
Absolutely spot on my friend. Pre-cleaners make the situation worse as it can increase the vacuum on the ductwork. Other things include running with a clogged air filter which also increases the vacuum hence the possibility of leaks through the air cleaner seal and the ducting. In this case if the air cleaner were at fault, both turbo's would be affected. This indicates a leak to the drivers side turbo between the intercooler and the turbo.
@@johnpickering5289 I was thinking the same thing, I know very little about this engine but if the dust was getting past the filter in the airbox why arent both the turbos in the same condition? Made me think the dust was getting in on one side only. I get why one side gets an oiling from the PCV as its plumbed to one side.
@@johnpickering5289 you are onto it John. Snorkels and pre cleaners can restrict airflow and along with dirty or restricted air filter element puts the sealing of the ducting to the turbos under stress. Result is dirty air pulled into either or both turbo/s. I don’t know if this vehicle has been but chipping an engine to increase power proportionately increases the air required exacerbating any leakage.
When I was an diesel apprentice we had this old timer come in now and then to help out. Old quote what he didn’t know ,wasn’t worth knowing, we had an old 555cummins in and the customer needed it to last another 6mth while his new truck was being built. The engines wasn’t happy, excessive blow by, aero start was its favourite inhalant. Old Jack has a look , a listen, a fiddle and goes back to his panel van and pulls out a can of Ajax. Ajax back then was a powered in a foiled cardboard can. He removes the intake pipe and get me to start it up. While revving the engine he takes a tea spoon of Ajax and lets the air rushing around it suck in the Ajax. It actually gave the old engine it’s ,compression back and it’s aero start addiction was a thing of the past. The Ajax was like a re-ring. If I didn’t see it with my own eyes I would have dismissed it as a myth.
I would of thought if it was a problem through the main air intake then both turbos would be dusted. However only 1 has a problem. That more likely suggests a loose inlet hose/pipe after the air flow splits in two to each turbo.
My comments for what they are worth. I have a 200 series 2012 completely unmodified bought from new. The only part other than regulator maintenance I have had to replace is the alternator. I suppose most problems people have with the see vehicle is because of the modifications they are making. Keep the vehicle standard and avoid all these issues. The vehicle is extremely capable it doesn’t need anything!!!
Maybe, however I would disagree that a standard 200 would be able to tackle and successful drive out of the terrain I use it for. Don't get me wrong, they are awesome vehicle stock, however like everything there are limitations. 👍
Here's hoping yours continues flawlessly for many adventures to come 🤞
Very familiar story. We left Perth on our 12 month lap at the start of Feb this year. Got 20kms out of Ceduna when the vanes seized in my drivers side turbo. Nursed it in to town and had to wait 13 days for parts and fitting. Had a few more dramas with the car over our trip but well worth it for the whole experience. Great vid and thanks for sharing 👍
Sorry to hear that mate, I know the feeling! Interesting to hear that most peoples experiences if all in the drivers side turbo...
Well either way, I'm glad to back on the road now and hopefully my cruiser follow's in yours footsteps and is problem free for at least the next year 🤞
More likely to be just a faulty actuator or possibly the variable vanes gunked up with exhaust soot . That " dusted " turbo didn't appear to be very damaged . If the shaft isn't wobbling or the fins damaged it would still work . I believe that the actuators can be purchased separately now .
Yes, I also noticed this, the turbo vanes still appeared to look ok, no signs of wear or rounding of the corners from what I could see. Nathan didn't really go into examining the turbo condition other than mention the scarring of the intake.
@@mrdoodle8748Bloke didn't even know which was exhaust entry and exit.
Years ago I had trouble with a TD5 Discovery and a TD4 Defender. Factory rubber turbo hoses kept internally delaminating restricting airflow and limp mode. Once I upgraded to after market silicon hoses and better clamps the problem never returned.
Nathan, I had to replace both IHI turbos on my old 2012 200series at 110,000km. Codes were P004B (left turbo) and P0046 (right turbo) and the problem was it would go into limp mode whenever I towed the caravan up a decent hill. No evidence of dusting. Turbo shop suggested the issue might have been the vanes getting stiff, which increases the current draw of the stepper motor which triggers the code. They had brand new turbos on the shelf because they replace a few. Just 200series life. I had had enough so now touring with a VDJ78 Troopy which has a single Garrett turbo. I know the guy who bought my old car and it has given him no trouble over the past 3 years since the repair. Yours should be fine now, but my opinion is the IHI turbos are not the best. Enjoy your lap of the country!
If you pull your intercooler off and check I think that you will see lots of the dust has been cought in there, the oil from crankcase breathers coat inside the cooler which then catches the dust.
Wipe around the intake manifold (after the intercooler) with a clean cloth to see how much has gotten through.
You may be surprised.
In the 4 years from new I had nothing but issues with my 200 series. It just wasn't reliable at all. I sold mine when I realised dust was getting past my filter. I went to a Y62 Patrol and it's been awesome. Average the same fuel usage and cheaper overall and zero issues in my first 2 years. All the best mate, I hope you get it all sorted.
I hear you mate, there have been times recently where I have thought the same. The amount of time and money that has been spent on this vehicle is hard to come to comes with.
All part of the passion with this type of industry I guess...
Have a look bet there is same amount of dust past the air filter...
What a bloody nightmare Nathan. I love my 200 but was aware of the Airbox issue before I bought mine. While checking out potential vehicles in 2018 before I settled for the one I bought I looked at an 18 month old 200 VX at my local TOYOTA USED VEHICLE dealership. Took it for a run and it was less than impressive. Brakes and power didn’t feel right for a rig that should have felt near new. Parked up the truck on the way back to the dealership and upon closer inspection there was red dust in every crevice that was missed to clean. It had been a dust pig in its past life and I suspect western Qld and NSW looking at the log books. Maybe a rental or ex gov perhaps. Popped the airbox, hand up inside intake and there it was. Hand absolutely caked in red dust that had entered the engine. I showed the Toyota dealership and their response “don’t worry about it mate it’s still got warranty on it”. Thanks but no thanks!!
The first mod I Did after suspension on the rig I bought was to fit a Radius airbox made locally here in brisbane Capalaba. I also fitted at a later date a K&N. I’ve just complete a 7000 km trip for my long service around west and far Nth qld towing an Austrack 15 and the cruiser performed seamlessly (did I mention I love my 200). I did a white cloth check on the intake when I got back and relieved it was spotless. Relieved?!? Well the thing is just doing it’s job after all. I am really surprised Toyota missed this issue.
Whatever aftermarket airbox you decide on I think it’s a very wise move and investment especially if you put your feet into some dust. As to why only one turbo had dust in it that may be a question for Toyota themselves. A bit strange. Maybe there is another issue there. Now, most importantly, enjoy your trip and safe travels through this amazing country of ours 🇦🇺
Sorry to hear about your troubles with the car, I’ve got a 2004 100 series and see no reason to update to the new 300 or the 200 before it. I’m going to build a 105 into a fun truck for half the cost of a new LandCruiser. The two cars will cover everything I will want to do and I have great confidence in there capabilities and toughness.
I agree with you there mate. Sitting on gold and I would be doing the same thing!
I dont agree it is a dusting issue, the VNT Turbo's are prone to fail on all Toyota models, not just LC200. Disconnect the actuator on both the old turbos and you will find that drivers hand side turbo is siezed or very stiff, that is why it failed.
I note your comments regarding dust ingestion in 200 series. The Donaldson precleaner is a big part of your problem.
They used to be used on Farm 🚜 tractors years ago...not anymore. They allow dirt to enter but trap most of the dust. The newer Vortex precleaners are automatically ejecting 98% of particles....I wish you luck with "The Big Loop " The 200 series will get you there.
Thank you Nathan truth about the 200 series must be upsetting the Toyota fan boys
Most mechanics know how much of a nightmare the engines in these are to work on . New crate engine from Toyota is around 19k , no injectors or turbos
Hey Nathan
Same thing happened to us when we bought our landcruiser from a Toyota dealer in Perth. The vehicle was originally from Melbourne and it got sent for sale to perth. We ended up flying to Perth to drive the cruiser home to Melbourne. During the drive, somewhat 200 kms out of Perth not too far from Avon caller Toyota our car decides to go into limp mode. No scanguage, no ultraguage and no idea.
We managed to get codes cleared and drove for 5 minutes before car was in limp mode again .
We weren’t driving this car home.
We later had the car towed to midland Toyota and they where awesome. The fixed the car and flew us home to Melbourne. It was a journey I wanted to do first time in the cruiser. I was shattered.
Enjoy your trip and your truck will be right
Respect and a big thumbs up for Midland Toyota.
@@dustyfarmer yes 100% they where the best and dealt with the situation. They where embarrassed by what had happened.
A quality aftermarket airbox should be the FIRST mod for any owner with the v8 diesel. This happens so often it baffles me why people don't know about it or do it.
Thanks Nathan - as always - for your thorough, intelligent and measured description and analysis. We all learn enormously from your superb videos, and I especially appreciate them as an overlanding LC200 series owner. I also have a Donaldson pre-filter and have recently ordered the new Donaldson XLC200K airbox. I wonder how much of the problem might have been "seeded" by the previous owner - would the pitting in the turbo possibly suggest a very "old" issue?
There is absolutely no need to apologise for any of your videos. Every one of them is informative and engaging. Can't wait to see your travels and adventures with the family on the big lap. Enjoy every moment!
GSL fab makes a 200 series air box that you can see what it looks like on the clean side of the filter before it goes into the engine, stainless steel with clear Perspex inspection lid and triple crush seal gruve for the square filter . it's made so that any fine particles that might get through the element you will see on the inside of the clear Perspex , if it's clean you know that you are still fine to go on, but if you start to see any residue it's time for you to do maintenance.
Sorry to hear the news Nathan. It would have been a horrible time for you being away and not being able to do all that much. Yes, things could have been worse but at lest you now have a plan moving forward. Stay safe mate and I'm sure a lot of us are looking forward to the van reveal. Cheers,
It wasn't a whole lot of fun, but we are back on the road now an looking forward to what is to come!
The reveal is all uploaded and set for tomorrow morning! Can't wait to show everyone.
Hopefully we'll be able to catch up somewhere on the road now that we have started our big lap 🤞
I'm sorry to hear about the dusting. But in my opinion, I don't think it was an air box issue. If it was, it would have dusted both turbo's.
I'm thinking your problem might have been in the intake pipe between the air box and driver side turbo. The clamp might not have been tight enough and let some dust in. Causing one turbo to be damaged and not the other.
On my 79 I've replaced the std air box with a Patrol Docta unit. Great fit and works great. Coupled with that, I'm running the Uni filter that I clean every 2500km. But every time I'm under the truck, I look at those plastic pipes and hose clamps and think....man those things are flimsy! Those pipes could flex and move just as much as the factory airbox. The problem is, we never inspect those pipes and would never know if they let dust in...! 🤔
That’s it. Pull intake apart and find the point where it goes from clean to dirty.
I tend to agree with you. If it was the airbox then your hoses to the engine would be packed with dust if the turbo is anything to go by and it would be both not just one. That much dust would also most likely compromise your MAF sensor.
Is it a possibility that the little hose that was disconnected could have been the culprit since you had a vacuum and it actually sucked the dust in there over thousands of k's?
Good video, it’s great to see some honest owners breaking down the myth and mystique surrounding Toyota Engineering. They make great vehicles, but they do have issues with design and application like all manufacturers.
Absolutely, there is no such thing as a perfect vehicle, however the LC200 is still a great vehicle
If it's the air box why only one turbo?
OMG!!!! What a story. Let’s hope the Landcruiser enjoyed all the attention it received and behaves perfectly for your trip around Oz. Good luck! 😃
Haha, it sure was! Definitely had some up sides though, like exploring the coastline and chasing waterfalls. Here's hoping for a trouble free trip here on in 🤞
When you do river crossings you need to understand a bit of physics. Those Turbo Electric Actuators get very hot. when you dip them all of a sudden into cold water they suck in water like a Sponge. Then the ticking time Bomb starts. Are we learning yet?
Hi mate, i have a 79 dual cab a 300 as a company car… owned several v8 70s, 200s, as well as 6 cyl 75s. Got a nice fj 45 in the shed.
Recently been on a 3 million acre cattle stn with v8 utes. All have the after market air filter box as the plastic ones deform in heat and cold and under load.
Nathan thanks for Posting. What a bummer. Good on you for having great adventures with your family. It will be worth it.
You could have called Andrew at Berrima Diesel.
Thanks nathan. Sorry to hear of your bad luck, but your excellent explanation is sure to help someone else prevent this happening to them. Keep the excellent content coming. I do hope you complete your trip with zero issues and then rebuilld or new engine.
Great story telling. Sorry to hear about your troubles. The old filters on the old Landcruiser’s were mint. These plastic fantastic shit no good.
What a tale! When I got my 200 series with 100k on the clock. I was shocked at the amount of dust present downstream of the air filter especially on the passenger side turbo intake.
I boroscoped the turbos, they looked ok, no signs of rounding or damage to the turbo vanes. I immediately bought a Moonlight Air Box which works well. My injector values are good but I am concerned if some damage has already been done though there are currently no signs of damage, e.g. excessive oil consumption, excessive crankcase pressure, excessive oil dropout in the catch can.. A great engine let down by a shithouse air box.
The stock Toyota airbox is fine if you know how to correctly install the stock paper air filter. Those oiled Unifilters soon lose their surface oil tackyness in dusty conditions they rely on to work & then pass plenty of dust through their open cell foam. Fit one of those Terrain Tamer airbox seal kits & you'll be good, if you pay attention to the paper filter install & don't roll the seal when fitting the lid. Unifilters also coat the MAF sensor in oil film.
@@dustyfarmer my two bobs worth.
I had a new 2002 Jackaroo and was headed into the Simpson, so I ordered a unifilter oiled air filter.
We left on the original paper element, I was religiously checking air box exit (intake) monitoring for dust intake. (Twas my first diesel engine, hence over conscientious).
To my delight it was always clean but once I noticed dust was getting past the original paper element, out it went and in with unifilter element.
By days end oily dust particles lined my air intake. I was bewildered. By day two it was truly noticeable. That's bullshit I says.
I gave the original paper element the best clean I could and refitted it.
As soon as I could I got a genuine replacement paper filter and all was good.
On returning home, I took the unifilter back to ARB supplier whom sent it off for analysis. To my horror, it was determined not to be faulty and no refund was forthcoming.
One bitten, twice shy.
I have run genuine filters eversince in everything but a 76 series I was silly enough to buy.
Dust got by no matter what filter I used, so I used to lighty brush & vacuum the S/S gause clean just prior to sensor. Always a concern. I was never truly happy with the 76 as a vehicle, it is so over rated, so sold it off went back to Jackaroo's in preference, so under rated in comparison.
Now in a Y61 Patrol running genuine paper filters.
You are right, that oily dust would have to coat the MAF sensor.
You must monitor intakes beyond filter closely, doing that avoids costly repairs Nathan experienced.
Hey Ian(?). On the Simpson trip, how often were you checking the air box exit please mate? Every night after a days run or sooner? Just keen to know so I can start doing that too on any dusty runs I do. Seems like a simple but practical thing to do 😎
@@ianweal3081 Hi Ian … I just posted a question to you but not sure if I did it as a reply to your comment so you might not see it 😮
@@PaulMotu hi Paul, as I mentioned, it was our first diesel so I was very conscientious of dust bypassing filter creating issues.
What I neglected to mention (once I re-read my comment) was I was travelling in convoy, hence consistently drafting dusty air.
To answer your query, I checked air box, filter, and intake nightly. Pleased I did, as I got ahold of the poor quality of the non genuine filter quickly.
NB. If travelling solo continuously drafting clean air nightly would be overkill possibly but I was in convoy.
As mentioned I now drive a Patrol and religiously utilise genuine filters that are oil impregnated paper.
They are truly good, but I had an offer to try a non genuine product.
Noticed immediately it was just paper without oil impregnation.
Was it effective, I'd have to say yes but I don't believe it captured the finer dust particles the original oil impregnated paper does, so back to originals only.
Now days, if I'm in convoy on really dusty terrain I fit a snorkel sock.
I carry two snorkel socks as they can restrict / block air flow quickly, hence mid trip dirty one off, spare clean one on.
These capture a bulk of the dust, nightly wash, re-lube, refit if required.
If not required I immediately place the cleaned re-lubed socks in snap seal sandwich bags ready to use when required.
Hope this clarifies your query.
Feel ya pain have been down this road with the exact same faults and replacing turbo’s not a cheap exercise. Thanks for the video
Ahh, sorry to hear that mate. Yeah, not much fun but all part of the process I guess...
Send an oil sample for analysis and it will help to determine whether cylinder wall material has scraped off into the oil, and how much dirt is in there. Send those two turbos off to a turbo specialist and have them upgraded for next time....
That sucks man, feel for ya.
For that reason this is why I got a Y62 Patrol. Less things to go wrong with them and parts are alot cheaper than Diesel engines.
Big Oz Explorers have been lapping for 2 years in there Patrol and had no issues.
Good luck on your lap, I'll be watching 👍
Did you do a compression test? I mean, if the values are all still fine and they're all close to each other, than chances are the motor is fine. On top of that, the damage to the turbos could have been before the installation of the uni filter. Though, the factory airbox is rubbish.
The most likely culprit of those turbos will be the motors I reckon. They won't be moving the vanes.
That is rough. I guess it’s better to happen before you left for your trip. Great insight into how the turbos actually get dusted.
Absolutely, that is definitely the silver lining. Couldn't imagine the extra stars having to deal with all this in a remote section of the Nullarbor with the family in tow...
I have used a Unifilter since owning the car and since using it have never had a dust issue not even that fine dust you see in the lid when in the sunlight that you can wipe off with your finger so I am surprised you have had this dust issue. Usually it is the passenger side turbo that fails when it comes to dust.
Yes, I had the same experience in relation to the visual dust on the airbox... Maybe it was from before I purchased the vehicle, maybe I just missed it... either way, here's hoping the new turbos get me a whole lot further than the old ones 🤞
@@XploringOz Thanks, besides that bet you are excited for your trip. We are on the road most of the time and it is such a great country to explore. Are you going across first to the east ?
Wow! Not good mate, As Jaffa suggests Id go that way but, I know and appreciate your point on this too. Take care. Cheers Steve
Very sorry to hear this . We have ordered a 300 which has the same problem so looking aftermarket to. Hopefully you will be fine now and just enjoy your trip
Thanks mate, hopefully its trouble free from here on in. Good luck with the 300! They are certainly great looking vehicles.
Yeah I would be tracking down the problem by removing the air filter first and inspecting the air intake for dust particles from there forward, keep going until you find the culprit . Good luck!
Just a small issue that does not impact on your video main theme. The exhaust enters the turbo via the entry on the outside of the spiral of the exhaust housing, the exhaust exits via the central outlet. It is the exact opposite of the gas flow of the input.
I think Ian Dibley has a good point as only one turbo failed when all the filtered air comes in one main tube then splits evenly. A really close look at the pitting shows pits much bigger than dust particles, more like the size of sand impacts. There looks to be more pitting on one area also. Is it possible pitting happened some time ago and the turbo survived. Recent extra engine load with the new van caused this sticky turbo vane from poor oil circulation. Mobil make a specific Turbine Oil DTE series for high rev spinning engines. Why does Toyota lubricate diesel turbos with 15W-40 when DTE is available
If this can happen to you after being so careful you just have to wonder how many others are sitting on a time bomb. Good luck on your trip.
Absolutely, it is very disappointing on Toyota's part. Here's hoping the new units will last a little longer 🤞
Pt 2. They wont/dont run 200s as this issue is too severe. Prefering the prados as a station wagon. This is up in Newman. Even their workshop has a spare v8 rebuilt waiting. So, (i know you know), get the steel/aluminium box fitted asap. Pre cleaner (which i note you have) and once sorted should be fine. Toyota need their arse kicking frankly. (Cant tell u who owns the station but they buy plenty of toyotas) Me? Insold my 200 and went back to the 79. 300? Nice company car but id never own one.
I would keep an eye on oil usage. If it's getting excessive; it may indicate oil rings and cylinders have premature damage. Also bearing may have wear too (watch your oil pressure) It should be ok for your trip but keep it topped up.
Hey Nathan, even in such adversity you remain professional and objective, as always! And sooo cool I have to say! Highly admirable! Respect! Wishing you all the best for your next big adventure - I look forward to the videos!
I wish to add Mobil Turbine Oil thru the diesel turbos should be a separate circulation system and could be by a dual purpose power steering pump. Turbine oil is about half viscosity of 5W-30 at 100deg C and similar to Power steering oil which itself is close to hydraulic pump oil. These 5 cSt @ 100deg C viscosity oils provide immediate turbo lubrication when engine is cool and designed for 600 deg C turbo heat. The engine oil 5W-30 in DPF Toyota 1VD and 15W-40 for pre-DPF diesels is designed for reciprocating petrol & diesel engines operating up to 90deg C, NOT for turbos spinning at 80,000 rpm
So sorry to hear what happened to your landcruiser mate. I've watched all your videos and I know that you really look after your car. This turbo issue was reason l bought the y62 instead of the Landcruiser. Looking forward to your future videos.
Obviously didn’t look after it good enough since dust got in.
starting to wish I'd bought the Patrol now 🤨
Cheers mate, can definitely see some of the advantages in the petrol engines... particularly with fuel prices at the moment too!
your engine is fine, dusted engines use oil like mad
I know this as I used to work at Cummins
you have not told us if the actuator arms are free, i sprayed my Disco three turbo arm with a mix of kero and 2 stroke oil thru a long garden spray wand as they cannot be reach by hand, yes clean air is all the engine must have, is your snorkel pointing back
good luck
Feel your pain brother,going through this at the moment.
Geez after all those other tweaks that you have undertaken and the dust still got in. You have convinced me to change out my airbox for an aftermarket unit. Our cruiser only has 40k on it so I would like to see a few hundred thousand more without similar failures!
For sure, it was very disappointing. Here's hoping I can also change the airbox out to protect these news turbos 🤞
I use a K&N oiled air filter on my R51 and the airbox is spotless even after long outback drives.
They do need regular cleaning and reoiling but I have used these since my motocross days in the 80's and they are great if properly maintained.
For sure and my visual observations on the oiled filter from Unifilter were similar. Obviously I as missing something though 👍
Check out the exhaust turbine and see if there is anything loose. Variable geometry has moving parts. It will not go to zero boost over night from wearing out
Pretty sure they are fixed vane turbo's.
@@dustyfarmer What is the actuator for then ?
@@stewatparkpark2933 Regulating boost.
@@dustyfarmerhow do you think the boost is controlled ?
They variable, the actuator control the Van slide.
@@dustyfarmer you obviously don’t no how a variable van turbo works.
Hope your holiday is going well.
Mate I watched you video in your turbo issue.
Something to consider mate would be to check the induction plumbing to that particular turbo.
An air filter issue would usually represent its self equally in each turbo.
Again hope your trip is excellent.
Cheers
What was the final repair bill May I ask?
Bloody expensive hobby these cruisers that seem to be rife with badly engineered issues and full of probs if used more than a soccer/school drop off!
Also Nathan what profession are you in?
Water ingress to the Electric Actuator. The Turbo's are worn but fine. CCT Stage 1 are only $2,200 for the pair. #8 Cylinder will already be down Compression. So start prepping for an Engine rebuild next. The reason #8 is the same reason why one turbo is fine and the other is worn. They duct all the PCV air into one turbo. You guess which one..lol
If you could see the dust in real time you will find the most of those heavier particles end up getting swallowed by #8 cyl
Hey mate, not discrediting your knowledge, but I don't think it's right to diagnose and predict repairs and damage without first inspecting the vehicle.
Wow. So sorry you are another 200 series owner with the dusting issue. Terrain Tamer have a fix. Check out their filter that has a SS support that prevents the air box from distorting under pressure/vacuum. It may keep your 200 safe before you get your new air box. I hope all goes well from here o .
I do still love my twin cab 80 1HDT cooled boosted and on D-Gas and only 240,000ks.
Cheers mate, yes this was another consideration as a temporary fix. I'm lucky enough to have the new box now, hopefully only a couple more days before it's fitted
what a bummer, so sad you had this issue.
Wow an expensive way to make really good content. Great Video. I have just started watching some of your past videos. Very informative thanks mate
I feel your pain but I have no problem with my stranded air bocks the trick is toyota gen filter and some vass🙃 make sure it's secured and all good. The dusting was from blown off the map tube
Clean it new tube and super glue.
Unfortunately you have dusted 4 pots when your thinking about injectors do a pressure test on all pots
Wow what a roller coaster of trouble and mental stress.
A few things to think about.
Why is the left turbo so clean in comparison to the right?
Was the left turbo replaced before you owned the vehicle, or was the dusty air introduced after the air filter after the split to the turbo inputs? Was dust on the input to the intercooler only on the feed from the right hand side turbo? If there was no dust here then scenario one (left turbo replaced before) may be the reason.
Was thinking same questions
Very useful information, thanks for a great video 👍
Thanks mate 👍
Hi Nathan
Very sorry to hear about this misshape! And that you have to experience it just in front of your big trip.
Having looked at your vid carefully and read all commences till now, but I not understand several things there. My I not familiar enough with this Toyota V8 engine.
I deal with dusted diesel engines in our customers mining machines and they show first high oil consumption and not total boost pressure loss power loss and never a limp mode. When talking oil consumption I mean 20 ltr in 20 operation hour on full load. When this engines dusted the turbo charger blades are visible worn and the engine oil is much dust contaminated.
Boost pressure on a regulated turbo charger is not out to zero in a short time.
Would be interesting to know later what really caused the one turbo failure and how much it will cost you to renew the two cores on the units to get 2 pc 100% recon units. Are you then going to put them up for sale?
Please keep us updated, but now take your time and focus on your new van to get ready, enough mod work to do I belief.
Keep the sunny side up
Cheers
Crazy mate…what a story!!! I’ll send some photos thru of my turbos, similar finding to you…crazy dust evidence on drivers side, passengers side clean but compressor fins showing rounding and damage from debris impact (dust or oil vapor).
Not oil feed I guess. That would be some kind of vacuum inlet/outlet.
Should get the two turbos flow tested, could be just buggered boost actuators.
Seems a quality aftermarket air-box is a 100% must-do upgrade with the 200 series diesel. Good to know as I'm contemplating importing one.
Thanks Nathan for the info and your experience. I check my filter regularly as i live in the bush. I think i will replace the air box before my next big trip next year. Hope all goes well with your trip. Bravo from Victoria Australia
Mate I can recommend PSICO in Bundaberg QLD - if you haven't already made a choice. Their gear is first class and well under the price of other brands. Maybe worth checking out. I have their custom box and filters and it's going great !!
The pistons are coated with oil so that will hopefully mitigate some or most of the damage from the dust.
Not likely as the oil and dust act like grinding paste. Toyota have reluctantly replaced engines under warranty due to dusting. Originally they blamed the driver or said it was normal...a $45k job apparently.
@@ericjohnson6802 that makes sense.
#1 thing for me is why & how. There is obviously a issue somewhere that is letting in unfiltered air into the system. For the money you pay for a 200 you would think that Toyota would have an impeccable engine filtration system. The Uni filter is a bit rubbish good for motor bikes or race cars. I hope the engine hangs together for you. Thanks for sharing 👍🏻👍🏻🙃🙃
They do not fit proper diff breathers, either. Go look at a Geländewagen to see how it is done.
Terrain tamer stainless washer to put more pressure on the seal.
I've only just discovered your channel. As I am about to buy a 200, I started to do some research on any possible problems. Hence discovering your very informative channel. One thing I am VERY confused about is why only one turbo dusted? Doesn't all the air come from one source? If one is dusted, surely BOTH should be dusted at the same time? Is there a leak in the pipework to that turbo? It just does NOT make sense that only one is affected. Can you enlighten me please.
🤦♂️. 1 air box feeding 2 turbos but only one has evidence of dusting? No split in tubing supplying the turbos for the air box. I assume they’re supplied independently from the air box?
You are a patient man....I would have completely lost my sh*t and I have had 3 X 200 series but was lucky that nothing failed. Toyota have a reputation that is probably ill deserved when you dig deeper behind the hype. BMW had issues with a couple of their V8 engines back in the day and they stepped up and took care of their customers. I don't ever recall hearing Toyota doing the same. Good luck with your adventure and hopefully it gets you all the way around.
Yeah I hear you there mate! it is disappointing that Toyota haven't taken some sort of responsibility or even rectified the issue in the newer models!
Like you said though, they are becoming know for it and this will hurt their rep in time
Chances of both turbos failing at the same time, almost impossible however I suspect actuator damage to one turbo. If you have not already thrown them out it may be worth while to get the turbos bench tested independently if they are ok keep them as spares.
I still have them, however not with me at present. I would be interested to test them, but they are visually damaged. The turbines are coated in dust and almost look like they are pitted from constant debris
If you have time mate, take it to John at street quick performance. Just for a thorough check prior to your trip.
what was the fuel economy on the way back, plus total cost of fuel. Thanks great video.
Ah what a bummer of a trip Nathan sorry to hear that. Hope the LC holds up for your trip. If you come by Melbourne again and ever need a hand hit me up.
If it was a dust leak then it should be both turbos as they both use the same air intake. Something doesn't add up .
I did the turbo going up Bogong High Plains Road in Vic. I know all about limp mode. In my research I found that a lot of the major faults in the D4CB engine are caused by leaking injector seat washers. Apparently they should be cleaned and machined flat every 10 000 kms.
Sorry to hear that mate. I was in that area a few weeks back and know how steep some of those roads are!
Interesting! I'm guessing a proper leak down test would determine exactly where the loss of compression is coming from.
Have you done this clean/machine process since? Any findings from it?
@XploringOz thank you!
So I got towed to Bright and I asked them to replace the washers. Don't remember if they noticed anything there but the turbine was pretty mangled and i was lucky that remnants didn't go into the engine.
I'm due to have them seen to again in another 60 000 kms.
Sorry I can't be more technical seeing I'm a female 😉 have fun exploring 👌
@@vivienrk Yeah, its not much fun.
Here's hoping that you are trouble free for many more kilometres moving forward 🤞
Thanks for the reply 👍
@@XploringOz thanks Nathan!
@@vivienrk No problems, all the best 👍
You could do a compression test to check the current state of the engine and maybe it would boost your confidence or tell you that you have a bigger problem looming.
Convinced me to keep my Colorado
Considering you haven't mentioned compression test numbers it sounds like they were fine so engine will be fine for trip .
Nathan your knowledge on the Landcruiser 200 series seems to be epic, some advice please. I am planning a long overland trip in South Africa, my Landcruiser 200 is a 2015 model and have done about 220 000 km with a full service history at Toyota and not a days problem, love my vehicle. Do you think it's time to trade in or should I not be to concerned with the mileage. I must admit I am not a fan of the engine in the 300 series, would love any comments
Sorry to hear all the sh__ you’ve been through mate. Hopefully it’ll hold up for your trip.
Hi Nathan, well explained and narrated, albeit not an ideal scenario just before a big trip.
Do you (or anyone else out there) know if Prado’s with the 1GD are susceptible to the same issues. Everything I’ve read is about the 200 or 70 series
Hopefully you will be on your way and all these troubles behind you
Cheers
Unlucky mate and very unfortunate timing with your big lap of OZ.
Don't let it get in the way of your big trip around this amazing country of ours. If I was to give you any advice before your trip, it would be to perhaps to get a compression test done on your engine just for peace of mind at minimal cost. Other than that, it's a cruiser mate, drive it and take care of any problems as they arise👍
as always well done ..hope the thanks may buy you a beer when you sit down next to the new van ..
Thanks Tom. I will make sure to have a beer on you when I can finally relax when I'm back on the road! Hopefully we'll be able to catch up soon when I'm over your way 🤞
Bloody hell Nathan what a horror story, a little funny only dust in the one turbo may indicate the pipe to turbo I believe is has an O ring wondering if the dust leak is near to damaged turbo. I think getting a compression test will answer some questions ,if the compression was higher on the side the turbo OK compared to damaged turbo side it might rule out the airbox/ filter, the compression would give a reasonable idea of the engines health. Like yourself I have hanging out for the Donaldson unit & it certainly looks promising I will have one in about 3 weeks .Best of luck with things you certainly have been though the ringer.
Great story pity the way you’ve had to do the fix. I have been keeping eye out on the new Donaldson filter lately so thinking 15% off this Black Friday cyber Monday weekend I’ll be placing a pre-order.
Funnily enough mate, Western Filters have removed the Powercore from their website, just in time for Black Friday sales. Let me know if you locate one with 15% off from them.
@@steveeylward I have noticed and cannot find within their website. “Matesrates” code will give you 10% allday everyday
Western Filters have confirmed by email that the 200 series Powercore air box is a set price & will not be discounted.
If it was the air box, wouldn't both turbos show damage, not just one? sorry you didn't really explain that. also what are the target boost pressures?
Mate, what a mission. I bet you considered buying another vehicle while you were in Victoria. About that dirty fuel. Can you be more specific where you may have gotten it? Do you think it was mainly water or just crud from the bottom of the garage tank? That's always one of my concerns when going on a trip.
Yeah mate, for sure. I thought about a lot of things 😆 🤦♂️
I'm pretty sure the dirty fuel was from a service station in Narrogin, WA as this was the last place I filled up both times... I think it was just dirt from the tank over water.
Definitely pays to keep a couple of spares on hand though
Nightmare. On my new 76, I've gone with a Donaldson pre-filter (after watching your videos) and a Moonlight Stainless Airbox. Seems good so far, might be worth looking into ....
Looks like he has a pre cleaner on the snorkel.
Great story.
Do Hilux's run the same variable vane turbo?
Have seen Donaldson pre cleaners on safari snorkels.
Hey mate, I haven't heard the D4D engines suffering from this issue nearly as much as the VDJ's.
It wouldn't hurt to prevent dust going into the airbox though, just have to make sure you get the correct size so not to restrict the airflow under acceleration.
I don’t see the logical link between airbox dust performance and only one of the turbos suffering from signs of dust damage. If the airbox was at fault, one side would not be clean. Did you or your mechanic check for for any cracks or air leaks on the pre-turbo intake? Particularly the side that failed? You should perform a smoke test on the pre-turbo inlet and ensure there are no leaks before you potentially munch another expensive turbo.
