Why Small Turbocharged Engines are a Failure: Nissan MR16DDT Teardown

In this video a Nissan MR16DDT engine is torn down to see what's inside and how it works.
The Nissan MR engine is 1.6L 4 cylinder turbocharged engine that was designed with economy in mind. The engine in this video was from a 2014 Nissan Juke with 160,000 km on it and had a severe oil burning issue.
Smaller turbocharged engines make use of technologies such as turbocharging, exhaust gas recirculation (EGR) and direct injection to make more power out of what would otherwise be a gutless engine. These are compliance engines meant to achieve fuel economy standards, however at the sacrifice of longevity.
The failure of this engine was impart due to a lack of maintenance but also the design of the engine that has little tolerance for carbon buildup, oil starvation and tarnishing. Direct injection means the intake valves don't get cleaned, combine that with turbochargers, EGR and PCV systems and dynamic cooling systems that allow oil to enter the intake and these engines will start to fail prematurely.

[@michaelbrinks8089]

What blows my mind is automatic transmissions and how they managed to figure out how to get everything to work. It's very hard to wrap your head around. How moving fluid is making it shift when needed. The "worm tray" is a maze of crazy fluid passages. The torque converter itself is incredibly brilliant (although I think the whole fluid coupler was invented before the AT & incorporated into it.) If you get bored look up how an AT torque converter works. It's pretty amazing ,that some fluid in a little round thing plus centrifugal force can move the entire car. In an AT their is literally no shaft or direct mechanical connectetion from the spinning engine crankshaft the transmission drive shaft. Transmission fluid connects & holds the 2 shafts together.

[@publicmail2]

Correct, compare a AT to a CVT which is simplicity, with 5-10 mpg increase.

Why Small Turbocharged Engines are a Failure: owners don't realize oil changes are important

[@jamesmedina2062]

people are so dumb and stupid nowadays that they think the extra power is free!

[@TheMarcQ]

You can't really blame owners when manufactures make oil rings 2 times too thin and tell owners to change oil every 20k miles

[@WeeWeeJumbo]

@@TheMarcQ you can definitely blame the owner of this engine for its condition

[@SkylineFTW97]

Turbocharged DI engines (DI engines period really, but especially turbocharged ones) need their oil changed SOONER, not later. Direct injection comes with oil dilution as an inherent tradeoff. It depends on how the car is driven and how often it's driven (low speed and infrequent drivers get it much worse), but all DI engines have it to some extent. And the only way to keep it in check is so shorten your oil change interval. I do it every 3k in my 15 Honda Fit. I did it every 4k in my old 13 Honda Accord and 09 Mazdaspeed 3

[@oscarlmolina]

Great video, as always. I find it worrying that engine manufacturers are not coming with a solution to the carbon build up on direct injection engines, and instead, they are relaying this problem to the end user as another "maintenance item"

[@savclaudiu2133]

Carbon build was solved long time ago of course by Toyota with the D-4S system that has both direct fuel injection and port fuel injection, with the first implementations already on 2007.

[@oscarlmolina]

[@chihirogustafson8557]

Unless your car requires premium running premium doesn’t do you any favors. Premium just changes octane rating which is the pre ignition resistance rating in essence. I have to run premium because Lexus requires it. Best thing to spend your money on is quality synthetic oil, oem oil filters, and other proper maintenance.

[@danieldoss1987]

Yes. Premium is recommended by the manufacturer. I've run premium in all my cars with good results. I used to have a 91 Maxima. When I would run unleaded, it would ping. Never had that problem with running premium. That engine had over 300,000 miles on it and it never burned a drop of oil. Although I can't same the same for the Jatco transmission... @@chihirogustafson8557

This was a great informative video. Made me beleive even more why its so important to change your oil often and why you gotta treat GDI with extra maintainance in advance. Gone were the fun and less headache days of port injection.

[@boots7859]

Also GDI has a lot more oil-fuel dilution issues which should factor into your oil change interval. If I had a GDI, I'd be doing an oil analysis at 4-5K to see if while the oil might still be good viscosity is being reduced by fuel dilution. Feel sad for those folks simply going by the oil's label of 10K/20K oil change intervals...

Me and a friend rented a Nissan juke in Spain for our vacation. Half way of climbing up the small hill, the car was making weird noise, burning smelling was emanating through out the cabin. While driving on the highway the car stalled 5 times while we were doing 70-80 MPH. We were able to get to another rental in the nick of time before the car kicked the bucket. That was my first impression of the Juke and the last time I will rent another nissan. Used to own a Versa and that was also a issue too. Friend used to own a altima and the dash was completely destroy from the crack and heat.

Nissan cars are basically disposable products. Their reputation from the old era stayed in their old cars before Renault took over. Nowadays, they make the lowest priced cars and still make profit - so how can one expect the car to be well-built?

Great video! The first thing I did to my direct injected 3.6 was install a quality catch can and have collected all the fluid that it has stopped from entering the intake. To date at 35,000 mi it’s well over a quart. Not the answer to the engineering problem, but better than not doing anything. Also change with quality eng oil @ 3,000 miles or less without fail. Port injection along with direct injection seems to be a better solution to the carbon build up on the back side of the intake valves, because who wants to have a media blast performed @ 50,000 miles or less?🤷

[@boots7859]

Get an oil analysis at your next change. If you're engine is good and there isn't a lot of fuel dilution you might be able to be good with 5-6K. Oil change is cheap insurance, especially for GDI, however any named Full Synth should easily last 7K even on turbo as long as its not being diluted.

Another good reason to change the oil regularly

[@sajidmohammad3190]

Hey bro, you made a Camry Cluster swap video once in which you put 4 cylinder cluster at first for which your gauge were showing more RPM and then you put a 6 cylinder cluster which solved the problem. I think there is a simple resistor in the PCB which selects how much the needle should go up or down per pulse. You should make a video on it comparing them two to find out the difference and make the 4 cylinder one capable of running with 6 cylinder. Would be a great work!

Cameras instead of mirrors, solenoids instead of hydraulics, motors instead of solenoids, everything needs to be controlled by some sort of serial communications protocol which can be accessed over the air by the in car modem and requires regular software updates when hackers find the security key wad pilfered from an online tutorial. Get rid of buttons and move all the function to a huge massive touch screen stuck right in your face, move the seats with the touch screen, open the hood with a touch screen and we are working to steer the car with touch screen gestures. 98% of drivers use a cellphone to navigate instead of the huge touch screen but we have made no provision for this.

[@NickTrouble]

Thermostats pulse open and closed when warming up, causing the block to swing in temperature with varying heat loads until it reaches steady state. This can be reduced and mitigated with an electronic unit, and is able to remove heat quicker when under a short duration high load acceleration. Additionally it will allow for quicker heating in a cabin with selective heat load

This is a MR16DDT V2(version 2) engine, if memory serves me correct, these weren’t put in non NIsmo RS Jukes till 2015. The version 1 was utilized until 2014 in the non NIsmo RS version Jukes. If memory serves me correct V1 mr engines didn’t have an EGR system like the V2.

[@notmyname9876]

The thing on the turbocharger intake side that you said "doesn't govern anything" is the recirculation valve. It's like a blow-off valve, but the outlet of the blow-off is routed right back around to the intake again, making a tight circle path for the air. When you close the throttle quickly, all the boosted air would have nowhere to go and that would overload the turbocharger. this allows the air to go somewhere and let the turbocharger spin down slowly instead of stopping abruptly.

[@speedkar99]

Thanks but that thing isn't an actuator. There's nothing that moves on it. It was more of a sensor.

that looks to be a good engine for tuning. stil it will need some special care. 1: it is a direct injected engine. this make it necessari to change the oil often. micro sot comes in to the oil and it act as a grinding paste. this attack every link of the timing chain and elongate it and it fails. 2: it is a direct injected engine so it need a secondary set of injectors to clean the inlet. this can also be used to put more fuel in to the engine for tuning. 3: the block is open deck. it will need a girdle or possibly new and stronger liner's. the problem here looks to be all in to bad oil maintenance. this engine need a oil change every 5000 mile MAX and it need to use a good oil that can suspend all the micro soot. for daily use i had tried to have a secondary oil filter to try to catch some of that micro soot.

[@michaelbrinks8089]

At least many cars now use a secondary port injection along with direct injection. I think only to keep valves clean. All those extra parts & complexity to fix the F-up of the direct injection idea. Kinda crazy how engineers & car makers decided to go with direct injection then pawn the garbage off to consumers knowing full well it'll clog. I guess if a person can diy they can find good deals on used direct injection cars with clogged intakes & diy clean them. My uncle won a 2016 Ford Mustang I believe it was a 4cyl direct injection only ecoboost turbo. He did the smart thing & sold it.

@@test40323 I know a lot do now. I'd have to look to find specific ones. Now I'm curious to learn about the whole direct injection debacle in modern cars. Reminds me years ago I had an 86 Chevy Z24 hatchback. Star bits weren't very cheap/ common in 86. In the 90s I was changing it's water pump & a pully was held on by 3 bolts. But one was a 10mm (no problem) the other 2 I had to make my own custom tools to reach 1 was star bit, the other was an Allen head bolt. So I had to cut up a star bit & Allen wrench & then glue the tips inside a wrench for clearance room to reach them. They did it 100% on purpose coz they simply could have used 3 10mm bolts. I hate giving car makers money when I know they purposely screw people over. I actually wanna build my own small fuel efficient vehicle. Something like a Piaggio mp3 (reverse trike configuration) but a lower seating position with an aerodynamic lightweight removable weather enclosure so it could be used in rain, cold light snow with no issues. Some removal saddlebags/cases & 3rd rear storage case & maybe some room behind the seat would be able to carry plenty groceries or travel gear. A 350 to 500cc engine & cvt trans would have plenty of power to keep up with traffic but the better aerodynamics 🆚 a motorcycle could get well over 70 mpgs. The original Toyota Prius got 100mpgs but they purposely reduced consumer version to 50mpgs. I suspect they don't wanna make a vehicle like I mentioned above because it'd be very affordable, easy & cheap to fix, and would greatly reduce oil sales = less profits for oil plus less gas tax revenues coming in for governments. I think if I could build what I have envisioned in my head. Almost every young person would rather buy it than more expensive car. Since it'd carry 2 people tandem seated, could be used yr round like a regular car, is fun to drive, cheap reliable and cheap easy to repair. Basically the affordability & fun of a scooter, but more stable safe coz 3 wheels reverse trike that could be drove yr round coz enclosure but also partially removable for nice weather.

There is not much that Italian tune ups can do to intake valves except make it worse by dumping more oil through the pcv valve...

I was not aware that the MR16DDT was prone to carbon buildup considering it having both port and direct injection. Did nissan get rid of the dual injection 2014+ ? If you search for Nissan's marketing video of the mr16ddt/juke, it shows how the dual injection works. Most common failures I saw were the turbo's oil return tube would get heatsoaked and coke up oil and eventually clog causing premature turbocharger failure; replacing that tube with an upgraded braided nylon tube resolved this. Second was the earlier years had an under-spec timing chain that was supposedly updated to prevent premature chain wear, nissan covered this repair for me way out of warranty at no cost. It looks like something has been updated on your teardown as the oil drain looks larger than the 2013 I owned. I also do not remember there being a thermal jacket on the oil return line. As you had stated, that engine was highly, highly neglected. I was very impressed in my nissan juke, easily a favorite car I have owned and driven with plenty of torque before spool-up, ripped around corners wonderfully, gobs of acceleration in a small form factor, great steering feel with active torque vectoring, plenty of clearance for off pavement adventures especially after putting slightly larger all terrains on the thing- although I really enjoyed the quick response and consistent torque output of the CVT, the car was plagued with a trash flawed transmission destined to fail early. Tuners got quite a lot of spare power out of this engine, especially in the manual models of the juke quite reliably as far as I am aware.

Was it a solenoid that controls the variable oil pump? I wonder if there’s a fail safe? It would suck to have the solenoid fail and then you lose oil pressure. You had to take a crazy amount of stuff off to get to the timing cover. I wonder if there’s a more direct way for a timing job or if it’s an absolute nightmare? The cylinder walls weren’t scored. The bottom end bearings were good. Just some camshaft wear. Was the oil consumption just due to stuck oil control rings? I wonder if they could be unstuck? Cam buckets are better? Aren’t they a pain in the ass to adjust? You’d have to take the camshafts and buckets off no? I like my Honda roller rocker adjustment and learned how to do it. My valve train also looks more orange than Donald trump due to 25 years of age and my brother used crappy oil and never changed it when he had it. Even after I’ve had it for ten years of using full synthetic oil there’s a lot of varnish but no sludge. I hope and expect my simple non VVTI, port injection, naturally aspirated timing belt engine can last until the rust eventually eats away my suspension connections. Thanks for the interesting videos!

I have a boost leak right now but I don't think it's from the turbo itself. I'm thinking my waste gate somewhere or in one of the feed lines. All the issues my engine bay has is strictly GMs fault... Shitty plastic parts, no heat shielding where it needs to be, heat shielding where it SHOULDNT be, thermostats open at way to hot a temp... They stuck the god damn oil line for the turbo between the damn cat converter and the exhaust manifold with NO heat shield... Could have put it directly in the combustion chamber and it would have been colder!

Looks like this engine oil consumption isn't much different to a VW/Audi engine that isn't maintained properly. I used to own an Audi with no oil consumption at all with 110K miles (177000 KM). The trick is to change the oil every 5000 miles. Currently, I got an Audi A5 80K miles and no oil consumption. The newer version of 2 liter 4-cyl turbo engine runs cleaner. The oil was totally clean when I changed it at 5000 miles. It is also very fuel efficient at 34 mpg with 252 HP (I can regularly get 38 mpg on highway drives).

It's quality Nissan-Renault engineering thank you very much! 😂 The previous Renault F4R was stronger due to the cast iron block, but it had its own problems (unrefined/rough idle due to no balance shafts, difficult cold starts).

That muck in the intake also wouldn't happen if they weren't running crank case vapors and egr back to the intake (he said it). direct injection isnt better than port injection..better mixing of the fuel with port injection + with the current knowledge of regular injectors they are just as accurate( see Injector Dynamics) . the only good about direction injection is that they can use auto-ignition like a diesel but they tend not to. So you basically get all the draw backs of a dirty engine and dont even actually get any efficiency

It seems to be that high pressure fuel pumps for DI are always cam driven. Are any electric pumps, and if not, why?

[@abdul-kabiralegbe5660]

Hmmm, are you referring to the power source of the pump or the actual mechanism of the pump? As I see it, for the drive system, while driving the high pressure fuel pump via an electric motor is advantageous in terms of making the high pressure system independent of engine/cam rotation, the current cam driven system is simpler and its output controlled electronically via a solenoid. As for the pumping mechanism, I doubt the pressures required by DI can be generated by anything other than the usual plunger type mechanism. In other words, the advantages of the conventional mechanical/solenoid system combination are too compelling to warrant change. Don't get it the wrong way but you seem unusually knowledgeable about cars than the average woman (or person for that matter). 👍👍👍

[@neolerades2987]

Pumps today are driven directly from the camshaft - so no losses and it's very efficient and simple. When driving with an electric motor, you first have to convert mechanical energy into electrical energy in the alternator - where you lose 20-30% of energy. Furthermore, today's cars are recharged by recuperation, so you lose another 10% plus you unnecessarily burden the battery and alternator brushes. Furthermore, the electric motor also has some efficiency, so you have additional losses and a limited lifespan. So you would get an ineffective pump that would have a short service life - and no advantages compared to the classic concept, I guess you don't want that.

The issue with putting small displacement turbocharged engines in production vehicles is that extra money and engineering needs to go along with it...the average driver will not be nice or change driving style to make it easier on the engine...or do extra maintenance...the engine needs to be built much more robust...not built down to the minimum to function at a price point...the carbon issue can be mitigated by changing the the average rpm its used at...make it only produce good power above 3000 and it will self clean and the higher average rpm will make it much less likely to allow carbon to stick anyway...

Agreed. More complexity on the assembly and the maintenance level.

Depends on how often you change the oil. Do it every 3-5k like you're supposed to and it'll go 200k+. If you follow the 10-15k service intervals a lot of makes are pushing, failure before 100 or 120k is normal.
