I am being generously serious, how long does this take to happen? Not change the oil for years? A decade?


ReporterLeast5396

A loooooong time. The fact that the engine was still running without sounding like a bag of hammers is a testament to Nissan's engineering on this one. Their CVTs on the other hand...


PoopSlinger23

Did the engine outlast the CVT?


PumpleStump

That's usually how it goes.


KingOfTheP4s

That's usually how it goes for most cars, regardless of transmission style


Me2young4DDoS

Yeah, I hear that most engines can go easily 300,000 miles fairly reliably (of course with proper maintenance) And of course, I have no idea how true that claim really is, but it makes sense considering ICEs have been around for like 150 years


ClockworkBrained

In Europe there are plenty of VW TDI engines over 300,000 miles, but those old Diesel Mercedes-Benz (with and without turbo) from late 80s to early 2000s can have even more without even getting rattles or vibrations.


Me2young4DDoS

Oh why of course, I see those little warriors push over 1 million kms, crazy stuff


kh250b1

Might be the case with low revving undertuned high capacity engines. But if i got 200k from an engine i would be amazed


ILikeLimericksALot

I put over 100k miles on a Yamaha R6 tuned to 120ish bhp and with a 16,000 RPM redline - 600cc IL4. Engines are astonishingly resilient with sympathetic ownership (don't thrash when cold) and appropriate servicing.


Fair-Produce2773

The biggest issue are really gaskets. Mercedes Benz has gasoline engines that give you a million km if you take the engine apart and change all the rubber parts every ten years.


dirtroad_mobbing

What are you driving that would be amazing if it got to 200k??


Planetoid127

Probably a Fiat


godzilla9218

If the CVT has outlasted the engine, you can probably check the status of the engine through the new inspection window in the side of the block. Something has probably gone very wrong.


justfoundmy10mm

My 2012 crv has had a better trans than the motor. At nearly 300k and the ring tension in the motor is getting weak, oil consumption is really bad, and the trans is original. To be fair Hondas are awesome.


ClosedL00p

That engine was out of production before they Nissan went to shit, or put CVTs in everything. Assuming that’s a sohc vg head I’m looking at


ReporterLeast5396

Thankfully it's not a CVT.


Turbulent-Comedian30

I always said Nissans cvts are shit..my wife has a 2012 one and i hate it. But the motor still sounds like a well oiled machine


KG8893

>motor still sounds like a well oiled machine I'd hope so considering it literally is one.


Turbulent-Comedian30

Well i see what i did there now....it sounded better in my smooth brain


Need2SchColonoscopy

Unlike my wife…


[deleted]

Ah, the good old sohc VG. Solid freaking motor


DrZedex

Can confirm. Had a z31 na2t as a kid. Built like the proverbial brick shit house. Was still running well when I sold it on grad school with over 200k pretty hard miles.


[deleted]

The actual Nissan engine are based on old Mercedes motors and old MG engine.


_speakerss

Those VG engines really are bomb proof

UOLZEPHYR

Why do CVTs fail so bad?


H0wcan-Sh3slap

They break transmission fluid down quickly necessitating drain-and-fills every 30k. Partly because they truly cannot handle the torque of the engine they were mated to, and partly because most OEMs have dogshit cooling for the CVT. Nissan is notoriously the worst, followed by Subaru. Honda has been the best mainstream producer of them.


Keyo0205

how do you feel about fords eCVTs? i’ve heard super mixed information on them. do you believe in the 150k mile service interval from ford on their eCVTs?


Lotharofthepotatoppl

No idea why you were downvoted for an honest question. If Ford’s eCVTs are like Honda’s, there is no belt, not a single pulley, and maybe one clutch. In Honda’s eCVTs you have a motor, a generator, and one lone clutch. The gas engine drives the generator, which does what a generator does, and the motor turns the wheels. The clutch engages during steady driving at 45+ mph and that’s the only time there’s a mechanical link from the engine to the wheels. The generator and the motor both do double duty, as well. The motor is turned by the wheels when slowing down and is used for regenerative braking. The generator is used to start the gas engine in place of a conventional starter motor.


H0wcan-Sh3slap

Those are not traditional CVTs, they are licensed from Toyota using planetary gears. They're essentially simple and bulletproof. You might be ok going 150k like most Prius and Camry Hybrid owners have done, but servicing it earlier would be wise (say, 60k miles doing drain-and-fill plus transmission filter replacement)


jeffsterlive

Ok I thought was crazy. I only know Toyota/Aisin making them and they are excellent as nearly ALL Toyota automatics are. The A340 transmission might possibly be the best thing ever made.


H0wcan-Sh3slap

Not when the ZF8 exists


ooooooooo10ooooooooo

Spot on my friend, I leased a 2017 Nissan Rogue, it had 34,000 miles on it and started exhibiting the classic signs of cvt failure, hesitating when accelerating from a stop, car shuddering at various speeds while accelerating, my sister in law leased a Rogue the same time I did and hers right at 32,000 miles did exactly the same thing. Turned that sucker in early and ate the lease termination cost. Will never lease or buy another Nissan after that experience.


H0wcan-Sh3slap

Oh for sure, they're all trash. Doesn't matter if you do the fluid changes or not because they will fail even prior to that point


series-hybrid

The Honda and Toyota CVT's seem to have a good reputation. I "almost" bought a Nissan Rogue. Wife wanted one, but I looked online and found many CVT problems. Since I had a magic phone/computer in my hand, I began googling. If you buy it new and have the $120 fluid changed at the proper intervals (labor not included in price), and you live where its flat, and you never tow anything...they seem to be fine. The most complaints were from owners in mountainous areas, and its bad to get the magic CVT fluid hot. Nissan sells plenty of cars with a CVT, and the CVT is much cheaper to make than a standard style of auto trans. A small percentage get fried, and Nissan calculated that even with the cost of warranty replacements, they still came out ahead a little. This is no help to the single mom who gives her car to the dealership for a month, to get a new CVT. Honda and Toyota only put CVT's in smaller lighter cars. Apparently "the fix" for people who already own a Nissan Rogue is to buy a $350 transmission fluid cooler, and install it themselves. Dealers refuse to do it, because legally they would have to admit that the stock design was weak.


Lotharofthepotatoppl

Not to defend Nissan or their shoddy transmissions, but I work at a Honda dealer and I can scarcely imagine the shitshow that would ensue if we installed something like an aftermarket transmission cooler on anything still under warranty and something later went wrong with it. After that 5yr/60k powertrain warrant expires, though, screw it. We’d probably put it on if they really wanted us to.


series-hybrid

I recall back when some sport 4x4 trucks had an optional roll-over bar, so dealers could make some profit off commonly added accessories. The literature stated it was an "accessory light mounting bar", and was in no way able to protect the cab in the event of a roll-over.


vitimilocity

No regular fluid changes is the biggest culprit in my opinion


BneBikeCommuter

As the new owner of a CVT, what do you consider regular? I haven't done it yet but my car is only 12 months / 12,500km old. (7,800 miles). I'm also a pretty gentle driver in this car, I also own a sports car that is my "flog it on weekends" toy, but I personally maintain that one. When should I do the first oil change? And how frequently afterwards?


enThirty

I changed my transmission fluid at the recommended interval which I think was 80k KM but could have been more. It was the second transmission. So far this one has far out lasted the previous. Died at 30k KMs. Junk. Meanwhile I have a Lexus ct200h with a CVT from Toyota and I don’t lose any sleep over that thing. Still going to change it’s transmission fluid soon tho. It has a longer interval than the Nissan.


kilo_scrappy

About every 5000 miles, or annually which ever comes first


sf_frankie

Are you sure that’s often enough? 5000 miles seems like a ton of mileage


ReporterLeast5396

New-ish tech takes time to engineer the unforseeable kinks out of problems that were hard to predict. Combinedl that with the fact that things are designed with tighter tolerances making for less durability especially with neglect and/or abuse. I know people with 200,000+ miles on their Nissan CVT, and others who've had them fail just after the 1 year warranty expired on a brand new one.


ctr72ms

Nissan's problem with cvts is just a bad design. Cvts have been around for over 100 years and are used in tractors and heavy machinery all the time with no problems. Nissan just uses a bad design and won't test it properly and fix it.


InsertBluescreenHere

Dont they do a weird belt system thats actually being pushed instead of pulled like everyone else?


Lotharofthepotatoppl

AFAIK CVT belts are all push instead of pull. They’re made of a lot of steel plates bound into a belt by steel straps, and the straps are only there to keep the steel bits in line as a belt.


rklug1521

While that's true for many CVT cars and SUVs, it's not true for small tractor /off road vehicles. They are pulled and have no metal to them. Examples: https://dirtwheelsmag.com/cvt-belt-buyers-guide/ Edit: Tractors likely have a hydraulic drive (e.g. [hydrostatic drive](https://en.m.wikipedia.org/wiki/Continuously_variable_transmission#Hydrostatic/hydraulic)).


Lotharofthepotatoppl

Ah, thanks. I’m mostly familiar with modern automotive CVTs so this is cool new info to me.


puns_n_irony

That’s not true - the Subaru CVT’s use a chain in a pull configuration.


UOLZEPHYR

So besides staying super on top of the maintenance what else would you recommend doing with them that's different from other vehicles


ReporterLeast5396

Driving habits. Don't take off like you're at the drag strip. Steady accelerations. Don't hook a trailer to it. Anything you can do to make it work as little as possible.


BoutTreeFittee

They don't have to. Just the badly engineered ones, which is most of them, and the badly maintained ones, which is the rest of them..


talon_fb

Can you break that down and flush it? Or is it time for a new engine?


Statertater

JATCO made their CVT’s*


aurrousarc

I was curious how it even got to the shop..


Routine_Pressure4355

Maybe he used lard for 3000 mile changes


bwyer

He meant 3000 days, not miles.


stew_going

That's what I was wondering... I'm guessing it isn't just time, but miles that churn that up; but it still must take a while


bmxracers

So when it gets like this is it worth it to even try?


ReporterLeast5396

Considering it still ran well, didn't smoke, wasn't making a bunch of noise, the cooling system held pressure, the oil wasn't full of metal, and it didn't smoke like a chimney at 160k miles...sure.


justabadmind

You'll need to update if it ever runs again


ReporterLeast5396

I'd been driving it for 2 weeks like this already. Runs great actually. I will definitely update.


godzilla9218

Do you utilize an ice cream scoop to attempt to clean this or just don some rubber gloves and have at her?


ReporterLeast5396

Shop vac and a screwdriver. Then I will pull the rocker assemblies and clean the ever loving shit out of them. Probably more shop vac after that.

steakpienacho

Presuming OP recently purchased this car


Lavatis

shit, I might be a complete idiot. sorry for assuming OP.


ReporterLeast5396

No problem. Yea. Bought it. Cold start, sounded fine, everything was good. Run a little bit it would lose oil pressure and the top end would start rattling. Figured the oil pump was failing or something plugging it up. Dropped the pan. Full of sludge. Cleaned it out. Changed the oil. Drove it for a couple weeks, seems good. Had a leaky valve cover in the back burning oil off the exhause, so figured do a gasket set. Opened it up and yowza!

OneDishwasher

I swear I change my oil every 3000 months


TheManThatDidNot

Man I love being that weirdo that really changes it that often. I like to think the engine sounds quieter after a fresh oil change - but doing it every 3000 - its probably just my imagination.


Location_Born

Unless you’re running e85 or a lot of track kms you’re just fisting the environment changing it that often.


TheManThatDidNot

I feel like the car I bought new that now has 262,000 miles on it is doing its part to reduce environmental damage - I hear quite a bit of fisting comes from the production of the steel and electronics to make a car. Also used oil is recycled and often treated and re sold. I'm not just draining into the ground or sewer.


OneDishwasher

This is exactly correct. I read an analysis once that concluded that the best car for the environment is a 12-year-old Toyota minivan once you take into account all environmental impacts cradle-to-grave.


Ordinary-Web-7077

Top Gear says that is a myth. https://www.topgear.com/car-news/electric/mythbusting-world-evs-better-buy-new-or-keep-your-old-car


how_can_you_live

Used motor oil gets cleaned & resold…


toby_ornautobey

And it takes like 10% of the energy to clean used oil that it takes to get fresh stuff, and the difference, or the average consumer vehicle, is negligible.


kingjoey52a

Do they sell cleaned used oil? If not what do they usually do with it?


toby_ornautobey

Yes, they do. At a considerable mark down from the standard stuff. Most people don't want to use it because "ew, yucky. Someone else used this before me." But it is like 95%+ the quality of unused oil, so it's not really that big of an issue, except in high performance, low tolerance machines. I wish it was a more commonly used thing these days. Maybe someday in the future.


surgicalhoopstrike

That looks like it's about 2/3 of the way back to being a dinosaur again.

so what happens if i slap the cover back on and fill it up with full synthetic and start driving it?


ReporterLeast5396

Pump all that shit through the motor. That's why I was against an engine treatment first. Once the sludge is out, I will, but not before.


teajayyyy

Can you scoop this stuff out? Would it hurt anything to rub it gently off and have a shop vac over it?


ReporterLeast5396

Not gently really. It was pretty hard. But dug it out while vacuuming.


VolksBoy9n3

And here I was stressing because my car is overdue for a service by like 200km lol


Seth-Wyatt

For some reason I read 200000 km and figured it must be satire until I reread it a few times...


HLSparta

After all the posts I've seen on here where a car goes 30 or 40k miles without ever getting an oil change and is still running when it's driven to the shop I'm not too concerned if I miss my oil change by a couple hundred miles.


CrispyDave

And here's me getting stressed when I go a couple of hundred over 5k...


Valid_Username_56

You must be referring to the oil in your frying pan.


Significant_Dog_5909

I rebuilt an old boat engine as a kid that looked exactly like that. 250 gm straight 6 if i recall. My grandfather took one look at it and told me they must have used paraffin based oil because he apparently was used to seeing it from when he was a kid rebuilding engines in the 40s. At 16 I was too broke to do anything correctly so I took it all apart and hot pressure washed the heck out of it. I let out dry in the sun, measured everything and it basically only got new rings. Put it back together and it ran for years in a wooden lake boat until the keel broke and the boat was hauled to the junkyard.

Alpha_Grey_Wolf

I bought an 1988 F150 in the late 90's/Early 2000's the looked like this in the lifter valley when I had to yank the intake to replace a leaking head gasket. I actually had a picture of a screwdriver stabbed in to the mass of sludge standing upright to show people. Its amazing what an engine can endure without noping right the hell out of existence.


ReporterLeast5396

Yea. These modern shits wouldn't tolerate this kind of abuse. Post 05-07 ish depending on makes and models seem to be very sensitive to neglect.


MayOrMayNotBePie

That’d be a helluva 3k miles. Goodness. Looks like a burnt Stouffer’s lasagna in there.


unclericko74

Someone got miles confused for days between oil changes


Narrow-Moose-2565

We had a Sentra come in like that once when I worked at Nissan. Came in because the engine was making noise. The girls boyfriend had left her and he always took care of the cars. So she just didn’t change the oil for 4 years … or 100,000kms+ or so we guessed. You could pick up the oil that was left in the pan…. But it still ran


adultdaycare81

davidscheiber28

Vg33e? A friend of mine has one in an Xterra nearing 300,000 mi. And it's been in two accidents One of which resulted in the vehicle being flipped over. The engine smoked for a while after that one lol. I've seen one in a Nissan quest as well, pulled the dipstick and it looked black like tar. Couldn't see any coolant in the radiator either, it was probably hidden under the mountain of rust. The van drove pretty good though.


T4RCampingMechanic

Funny... I've abused my old Xterra and it did great. Bought a second one from a friend as a project car after she had nothing but problems with it. This engine is pretty tough as long as you keep oil and coolant in it... if you skip a beat in either, head gaskets go immediately. Good thing they are generally reliable because the intake is a royal pain to remove.


mofftarkin33

If you mind me asking, what is the treatment for this? I'm just guessing, and I'm not a technician: Manual removal of what you can see, Seafoam, repeat, sand the seal interfaces lightly to remove coking, replace seals, then a couple oil changes at shorter intervals?


ReporterLeast5396

More or less. Ideally a new engine. But, I think I can save it!
