SKETCHY RETURN? Was The Customer WRONG? Blown BMW N20 / N26 Complete Engine Teardown
ฝัง
- เผยแพร่เมื่อ 1 ต.ค. 2024
- Another weekly dose of your catastrophic engine forensics! Every week you can find a new teardown of some abused, misused and/or poorly designed engine. I've got over 150 videos of failed engine teardowns on this channel.
Today we have a BMW N26 2.0L 4 cylinder turbo engine on the stand. This is essentially the same as the more common N20, with. just some different external parts like injectors. This particular engine is either a returned as defective or core return from a salvage yard. Between the loose parts, multiple heat tabs and other less than normal findings I am inclined to believe this engine has been in several different vehicles and worked on by multiple people.
These core engines always tell a story and its not usually a good one. Lets tear this one down and try to figure out what happened.
Why am I doing this? I own and run a full service auto salvage business in the Saint Louis area called Importapart. Part of our model includes dismantling core and blown engines to salvage the good usable parts from and resell. We do not rebuild engines, merely sell parts to those who do.
I hope you enjoyed this video and as always, I love all of the comments, feedback and even the criticism.
Catch you all on the next one!
-Eric

Dead engine, new parts? Sounds like me when I put on new clothes.
😉
I feel that lmao
Same 😅
Lmfao
More like getting a boob job
Eric: Lets see if she'll turn over.
BMW engine: I shall sing him the song of my people.
I wanted to like this comment more than once😂
Thank you for all the extra content this week! Your channel is awesome! Please keep cranking out tear downs, driveway Miata’s and more Lotus!
I love when you smash timing chain guides. They deserve the rage of a thousand suns.
They must feel the g forces.
it wouldve been really funny if the shot after the timing guides bit just had smashed guides in pieces on the floor in the background lmao
Especially N20 chain guides. They belong in a dust bin in Hell.
Bits of plastic on the floor that I would step on and probably fall.
all part of the fun@@kthwkr
Would have been interesting if you took the electric water pump apart. I think like 99.9% of the people here have never seen the insides of an electric water pump. Also would be interesting to get a feel for reliability. What kind of bearings do they use? Could you fix/rebuild it if they no longer offer the replacement part?
You shouldn't yield to the timing guide trolls , the coolant pump and oil filter trolls will smell blood in the water .
Absolutely! That's why you should always shatter plastic guides against a hard surface - the banishment spell needs to serviced once in a while.
The electric water pump seized and caused the overheating most likely. Driver probably noticed the temp going up, engine light came on, decided he/she was going to drive it home that way, and thar she blew!
Definitely! 👍
Millions do this no brain
When you pulled the oil filter, it really looked like a toilet in a gas station, and I was surprised there wasn't a cigarette butt floating in there.... It would have fit right in!
Thanks for all the content this week Eric. The Miata episode was interesting, cool car at your home shop. Personally, I would never buy a BMW, they can break your wallet when they break down. Did you spike that timing guide off camera? I hope so. lol I love the Saturday night teardowns and your comments🤣
Hey,this is my friends engine lol
Older bmws are great except for the oil leaks but I think bmw from the factory makes sure you engine is well lubed from the inside as well as the outside of the block. 😂 The problem with bmw is you should only buy oem or one of the other sellers who make oem certified parts for them. Because bmw aftermarket parts will work but not for long at all and I mean even down to the door handle carriers... I still own a 2006 bmw x5 4.4i and I love the thing it has just about 220,000 miles on it and still runs amazing... I will say though since I've owned it it gets new oil and filter every 4k miles and only using synthetic oil so maybe that's why it's treated me good. As far as parts lasting on them for an almost 18 year old heavy tank of a suv I had to finally swap out the factory airbags in the rear this summer which was a breeze to do.
Oh For anyone who does the rear airbags on an X5 don't expect your air ride to air up with it still jacked up. 😂😂😂 yes it drove me crazy for about 30 minutes trying to figure out why when the light bulb finally went off in my head. But im no mechanic by any means I'm just an average dude who is not scared to get my hands dirty. OH also for anyone that ever changes the water pump in the 2006 N62 engine don't watch the video about the guy who claims you can get the bottom water pump bolt out by not having to take the crank pulley off. Yes you can get the bolt out, but not back in, so just spend the extra 10 minutes of your life ans pull the crank pulley off and thank me later that you didn't try his shortcut. 😂😂😂
Very thankful for the 3 video week Eric this has been a Gr8 treat! I’m excited to see what happens to the jockey truck Cummins love the content!
Tip for BMW drivers: Move your seat as far forward as possible.
That way you can get even closer to the car in front of you.
And disable the airbags, they just slow you down anyway.
I think all of those drivers drive AUDI now, no?!
@@matthewmclean9734removing them saves weight, and the shorter braking distances from the lighter weight would be worth it. (Sarcasm)
They are after all, alphas, so they feel justified tailgating.
Snap Off the useless turn signal stalk while at it too ,it's useless on a BMW
B48 was a massive improvement over the N20. However, i do gotta say i still like the N20, as it essentially is an N54/55 with two cylinders removed, and a much, much shittier timing system.
i loved my n20
The B49 was even better... Helped us win the war...
The cost of the coolant system repairs that the B46/48 end up needing are substantial
I enjoy seeing these teardowns. It's personally something I'd love to do if I had the money, time, and even tools and whatnot. Primarily though I vibe with your channel quite well because I always loved to take apart stuff when I was younger, even tho most of that stuff was failed or otherwise nonfunctional electronics stuff that wasn't being used anymore anyways (that I also had permission to take apart too of course.) And while engines differ form what I did when I was young, it still fits in the general "take apart thing and see how it works and what went wrong." kind of deal.
Also a bit of a minor edit but... I have to personally wonder what the percentage of the watching audience of these videos is that is, people who know that timing chain guides cannot be reused, and don't mind you tossing them, as they'd probably do the same(I honestly would. it's fun if the timing guide is either just being removed for good in total teardown or being replaced for maintenance or otherwise), how many people are just trolls that like to just be silly in their weird way by acting like the people who don't know that timing chain guides cannot be reused. And then how many are well... the people who don't know timing chain guides cannot be reused. Like I really have to wonder that.
Watching while snuggling with the kiddos at bedtime… when you said the ‘the crank should just sheboopee right out’ they all start giggling and repeating it… thanks Eric I know what the most used word will be in my house the next week…
Keep up the good work!
30:00 Eric "The King Of Junk Miatas" surveying his kingdom
Eric please tell me you at least spiked that timing guide at the ground off camera
Dear PIG Mat,
Please sponsor Eric. He’s good for business.
Sincerely,
The Internet
Thanks of course for the usual teardown tonight, but thanks for the holiday Miata run through. Engine education 😊
Wow, the video has only been up for 4 minutes, and you have 457 views.
Hope TH-cam gives you enough money to make it worth your time.
Worth noting that a BMW n26 with no spark plugs plays the Lavender Town theme when you turn it over
I thought it was the theme from Thomas the Tank
You know it's Saturday when you have an auto-clicker set up to refresh the page at about 7:40 PM CST.
Dude I just want to say, your videos still have the exact charm that made me subscribe at first. The jokes, the play on words (sediment), and all the antics like smashing water pumps and timing guides that no one in their right mind would buy. Thank you for keeping the channel awesome, always eagerly awaiting the next video!
Spike the chain guides!!!
20 years ago an old timer asked me “you know what’s worse than used parts?” I said “no” knowing full well he had a smartass answer. He says “used, used parts” it’s in we’re seeing a case of used used parts here. Really fascinating
Nice teardown! I have a 2014 428i with the SULEV N26 engine which I love. The engine is very smooth and so punchy. So far its been flawless, but I am on top of the maintenance. The metal oil pan on the teardown tells me that it probably came from an xDrive model. Non xDrives were typically fitted with a plastic pan.
The shape of the pan to accommodate driveshaft/diff, and also the front axle hole at 20:50 tells us it's an xDrive.
Grotesque over-engineering. As a retired mechanic, I can say after decades of experience that I thoroughly loathe European car and engine designs.
I am curious if those electric water pumps are reliable and do they run on 12 volts or is there an inverter involved? I retired just before these engines were brought to market so, I have no experience on this particular engine.
Check out VAG Technic for some real nightmares.
I got an n20 in my 228i. I actually like it but I am aware it can all go wrong very easily. I stay on top of maintenance as much as possible. Thanks for this one - and the Car Doctor reference lol
you probably be fine. Wild tuning breaks all 4-turbos and second owners buying cheap Bimmers more likely too poor to afford or enforce good services
I bought a 328i at auction. Some of the timing chain guide were in the oil pan.
I wanted the electric water pump to get the treatment that the timing guide was going to get.
Thanks for all the vids this week! Glad you got some parts out of this teardown. Shame a bunch was damaged. How many Miatas could you build from all the parts cars you have?
Eric, you got to show us the Cummins You exploded 😂
it was Triple 6 for likes when I started watching and went up to 1.3K as I type this.
You know, for those "But That's a good part!" folks, maybe you could offer those bits for sale, at $10 MORE than a new part.
Smashing timing guides isn't an intrusive thought, it's the right thing to do.
Plus it's fun to watch/hear.
"Tomfoolery", you say? Perhaps. With a fair dose shenanigans, added in for good measure, I think.
Don't forget the high jinks and buffoonery too!
ERIC!!!! Please stop using the channellock adjustable plyers backwards, like you used on the oil filter!! Look at the jaws, they will tell you which direction, will give you the best grip.
I found myself wondering which series engines are the best, as I drive an N55 in a 2015 x5 S Drive. It’s been reliable but I’m meticulous about maintenance at 5k. Eric brings up the N52 giving a clue with some older NA engines. Still it seems all the newer engines are force fed, right? Are any newer engines any good?
One of these days Eric is going to work on one of those engines he has in the back and be like "oh hey, a piece of a bmw timing guide, how did that get over here?"
Eric , thanks for the great content. I find it cathartic and I watch a teardown anytime I am running on a treadmill or using the stationary bike. It eases the monotony. I’m currently working an assignment at Palmer Station in Antarctica and have been looking forward to watching your content from the 7th continent! Thanks again, Kevin B.
Your ability to learn faster than your competition is your only sustainable competitive advantage.
I'm the first viewer! I feel like somebody! keep up the great work/content sir.
have u ever tore down a 4L v6 from a nissan frontier. mines a 2013. 175000 miles no problems.
Hey I could have used that oil pump chain tensioner assembly for my 1826 m599 n89 motor. Lmao
I just wanted to go to bed (Europe). But this video gives me energy for another hour 😂
Personally I vote for an epic compilation video of you destroying every timing guide and water pump that's ever been through your shop. Dedicate it to all the trolls.
Make sure to say oops after each one since if you say oops enough times it makes whatever happened an accident.
The musical coils at the start were great.
I would love to see an Audi 2.0T TFSI EA888 CBFA (really just a Volkswagen tsi). Mainly cause that's what I have in my Audi and I wanna see for what reasons it blew up lol🤣
Loose head bolts, newer timing guides. Botched timing service???
Have you ever removed a radiator hose from a radiator, with out breaking the radiator inlet or outlet pipe? Plastic is not your friend. =P
I am glad I am sticking with older technology. I have never seen a valve system like that before, or balance shafts. Four pistons, one crankshaft, two cam shafts - done.
TWO CAMSHAFTS?? Young man, back in my day we where happy if we got HALF a camshaft and three valve springs. Four or five valve springs was reason to celebrate! We'd forge the rest of the camshaft from the remains of the Model Ts we had strewn about, and hammer-forge the parts together for a complete cam. Of course, we had to file the lobes to the correct shape, but a cardboard template did the trick.
You kids (including you, Eric!) have it so easy nowadays...
The head gasket failure is not a bug. It's a feature; a new design EGR system from Germany.
These BMW engines are very nice, very high end, and very complicated and very driveable engines. The buyer of a new BMW is very happy with it I guess. BUT: when they get older, with some mileage on the ODO, they will get a real pita because they are so complicated and expensive to fix. Also not very durable and reliable. Using a cheap poorly made electric waterpump that surely will fail is a recepy for blown engines. Unnessecary complicated engine. A good shop replaces this stupid waterpump as a prevention, and changes the oil much more often as the manufacturer states. Maybe, maybe, by doing this it will last a long time without big repais. Obviously it's not a Honda or Toyota by far.
From good cars they have evaluated in throw away cars.
Another video. Thanks Eric.
Valvetronic, BMW's solution to a non-existent problem... Why create something that is supposed to replace an actual throttle body but still requires a throttle body to work correctly, it's as stupid as the Vanos variable valve timing system and probably just as expensive to maintain or repair.
Looks like this one has been around the block a few times...
still waiting to see a GM 3800 v6 end up on this channel (they never blow up lol)
"Of course it's sketchy, it's a BMW," meanwhile, have you seen my driveway? Haha
How far that little candle throws its beams! So shines a good deed in a naughty world.
THREE videos this week! Is it Christmas already?
I just got a message supposed to be from you about scammers I tried to look at it tried to blow it up then it disappeared about a Facebook rip off of your account there but I don't have Facebook as I feel it's all a scam but wish I could help you cause your a great good guy trying to make it in life but I thought you might want to know
The heat cycles that aluminum goes through makes them lose cohesiveness of tolerances.
Join us next week, when our host disassembles an engine made entirely from heat tabs.
Pakistan truck repair will have that engine back in service in 4 hours.
Was literally just watching a three stooges video!
Wow, Blue didn’t make an appearance until the 12 minute mark.
Thanks for my Saturday night entertainment. I hope you and yours had a Happy Thanksgiving.
3 IDC videos in one week. Best Thanksgiving ever! Thanks Eric!
We learned a new technical term today: "Woil"...
This is why I love watching your tear down videos! This morning I learned about BMW valvetronic… What a weird design of engine. I don’t think I would ever have a car with this engine but I love watching you tear these down every week!
Keep up the good work!
Thanks for all the extra videos this week. That Miata you put back together correctly is a nice car! That video made me want one because they’re so simple.
Valvetronic is very reliable. Surprisingly so. It's the biggest reason these things are so fuel efficient. The throttle body is only there to keep the engine from screaming to high heaven if the valvetronic motor fails wide open. I've got 178,000 miles on my N52, and she purrs like a kitten with frequent oil services.
all the plastic chunks in the timing/pan area -- wouldn't that just be chunks of the busted valve cover?
I would be willing to bet the head is also warped.
I think that nasty water pump got off a bit lightly - you could have smashed it open so we could see what was inside.
Is that timing guide for sale 😂😂😂😂😂😂
Those Snack Packs taste better when refrigerated
high rate faliure and jose passing it on marketplace $2000=scrap OR HIGH MILEAGE
Whenever finding signs of overheating, you should check the heads for warpage with a straight edge in your videos. OHC heads cannot suffer much warpage at all since that messes with cam bore alignment.
I was hoping to see you slam the crankshaft on the ground like the other parts.
Look at the size of that turbo in the background!
The logical side of my brain says it came off a big ass diesel. The emotional side of my brain wants it to have came off one of those Miatas.
Oh goodie, an over engineered German engine, that creates its own problems.
The best. I despise German vehicles.
I just found out yesterday when doing a head gasket on my 6 G 75 Mitsubishi Eclipse GT engine the the intake valves open together but one opens much larger than the other only when my back kicks in they will both switch to a completely different cam profile and they will both open all the way could have something to do with it I thought they opened equally together I guess not. I actually bent a valve while doing a water pump and timing belt by hand how to remove the cylinder head heated the valve up with a blowtorch till it was red then turn the cam to where the valve was in the down position found a large socket the size of the valve gave it a good smack pick the valve back up by turning the cam rotated the valve heat is it up again lowered it and gave it a good smack again put water on top of the valves to see if it leaked it is now fixed. I also created a new method to remove a dipstick tube using vise grips and a pry bar it was super easy barely an inconvenience.
Absolutely spoiled us with content this week, thanks Eric!
And people who cry about breaking junk like used timing chain guides need to get a life... You should start selling them used head gaskets too!
I believe those valves had a different look because of the valvtronic system operation but I may be wrong, love the vids keep em coming
Definitely a builder and worth a trip to the machine shop.
Those vacuum pumps are kinda pricey if I remember correctly. Of course I'd never sell a used one to a customer. Maybe on my own car. That will never happen though. If it doesn't have a T or H on the front it won't fit in my driveway.
3 videos in one week?! You spoil us 😊
I've seen those head cracks before.
Nonetheless weather what ever caused it. Im still a strong believer in Shutting your engine off and NOT idling unless it is super cold outside. A running engine is an engine that is wearing itself out especially in these new motors. Junk. These people should consider a early 1990s GM 3.1 Multi port swap. Theyd do better. 😂😂😂
I know an old 3.1 Lumina sedan still kicking around despite a loud valve tick!! It'll probably see the apocalypse....
@@jacquesc3166 exactly. I had a 90 Lumina years ago, I got 2 oldsmobiles 92 and a 96 currently both still fully drivable, What an underrated engine those were. Underpowered sure, reliable and easy to repair absolutely, as they have all their accessories on top, back to front Alternator, power steering and Water pumps and a forever "steel" timing "chain" and most importantly you won't find any plastic parts in or on the motors all aluminum or iron. Not bragging but people are forgetting what cars actually used to be with the exception to increased HP and torque. Doesn't seem like a good trade off.
Other than the timing chain cassettes (and some other issues) the N20/N26 was a pretty stout motor. Sadly the long service intervals BMW has really didn’t help.
I sense some flim-flammery afoot! Perhaps portending a brouhaha? We shall see.
Most underrated channel 🙌
I am mad that you didn't smash the timing guide. Now you have to pick a side. 😂
Thank you so much for the teardown on Thursday! This has been a fantastic vacation from work
That magnetic crank trigger ring is one of the biggest mistakes the auto industry ever put out there - ask *any* Ecodiesel owner. What was wrong with a simple reluctor wheel bolted to the harmonic balancer? Oh I know, they wanted to keep people dependent on dealership repairs >_
For me, the engine is too complicated. As an experienced tech, you dive in. I appreciate your teardowns. Many thanks. I hope you and your family had a great holiday.
Witam masz rację starsza konstrukcja była o niebo lepsza nisz N26 czy N20 które trzeba cały czas pilnować to po prostu słabe konstrukcje...
OLÁ. Para quem é analista de motores este vídeo é muito importante uma vez que contém provas visíveis de de diversos erros. Um analista JAMAIS deve usar uma chave de impacto para com VIOLENCIA afrouxar qualquer parafuso. A destruição da peça com quebra é impraticável pois seria a prova de que a cor era bem diferente do pequeno pedaço encontrado no cárter. É visível que não é a 1ª vez que o motor é aberto. Trata-se de uma marca muito conceituada mas, neste caso, é possível constatar VISUALMENTE as diversas deficiências provocadas pelos cilindros algemados o que facilmente pode ser constatado com o PERFEITO uso de instrumentos adequados. Dificilmente encontrarão uma retificadora que aplaine bloco e cabeçote com precisão. As costas das bronzinas de biela acusam forte ovalisação do alojamento de BIELA. Tem mais...ABRAÇOS...Roberto Udo Krapf.
There cant POSSIBLY be people actually getting mad at you about the used timing guides, right?.....
I actually prefer the N20 to the N52. BMWs naturally aspirated motors do absolutely nothing for me. I got turned off to them on my E39. Gave Dinan close to $10k and got a measly 34hp on the M62TU. Screw that. I give Burger $499-$799 with a turbo motor and get 50hp+. I'll take the turbo every day of the week.

240hp from a 2.0 turbo 4? Pretty pathetic…. Maybe they have a ton of torque? Idk GM’s 4cyl’s blow that out of the water power wise, and do it with far less complexity. Just standard VVT, or in the case of the LSJ, 225whp from a supercharged 2.0, no VVT AND port injected not direct.
I tune in to watch you throw water pumps and timing guides. I’M PISSED OFF YOU DIDNT THROW IT.
TOU ARE A JERK!!!!🤣
I am still confused as to why anyone would buy an engine from a junk yard unless theirs was destroyed beyond repair . Salvage yards exist for one reason , to rip off the unsuspecting hillbilly . Only the Germans could make a four banger complicated ? Why the **** IS THERE PLASTIC INSIDE AN ENGINE ,last time i checked they get hot ?
