THE FAILURE THAT COST BMW $27 MILLION! 2014 328i N20 2.0L Engine Is DEAD And Here's Why
HTML-код
- Опубликовано: 28 сен 2024
- Today we tear into BMW's infamous 2.0L "N20" 4cylinder engine. These engines can be found in the 320i, 328i, X1, X3, and the 528i amongst several others. This is a core engine, purchased for the purpose of parting out. As with most core engines, I never know what's wrong until it gets torn down, which is the purpose of the video.
The N20 is an engine that came out in 2012 to replace the outgoing N52 inline 6. Many people regard the N20 as inferior for a multitude of reasons, but the biggest being its propensity for expensive repairs and failures.
Why am I doing this? My name is Eric and I own Importapart. A full service auto dismantler. Part of our model includes dismantling blown up, failed and otherwise bad engines to salvage the good parts. We do not rebuild engines, merely supply parts to those who do!

-Eric
I have a 2014 bmw 328 with N20. When dealer told me oil changes were every 15k miles i was like are you drunk? I did mine every 5k miles and still do. Current millage 60k. No issues.
as a former bmw tech, you wont have any. only ever saw issues on high service interval cars
My Saturday night is complete!
Saturday afternoon was spent watching a fella try to bring a Pantera home and now Eric find out why he wasn’t gonna make it
@@Gapines23 Same. I owned a Pantera many years ago. Always wanted one till I actually had one. Not a fun car to drive for a tall person. I find it crazy he actually tried to drive that home. Way too much rust and damage for that to be a 14,000 mile care. No way. He should have passed. I was told long ago that for every $1000 more you pay for a car you save $3000 in repair costs (or restoration costs).
Undoing the clamp and then cutting the hose, it’s the little things in life
So true.
the injector removal reference was hilarious
I find it easier to start getting it loose with my left, then a power-pull with my right hand to finish. Pulling injector, that is ;-)
Throwing empty brake kleen cans?I smell some rainman ray there-lol
another
I've seen a couple of these get close to 200k miles with timely oil changes...
The wastegate likes to get loose every 40k-60k miles...and there is only so much threaded rod to take up the slack LOL!
That’s when you take your own blue and bend it for “adjustment” 🤣
nice place for a engine computer... they took a page from GM/Ford/Chrysler
So much plastic in so many hot areas.
Good ol' planned obsolescence!.
Not like the BMWs of yesteryear
@@ragnarironspear1791 I miss my E30
Grab the popcorn, it’s time!
Fascinating stuff. I owned a 2010 MINI Cooper S for about five years. Never had any real problems with it, but always changed the oil every 5,000 miles in spite of the factory spec. Even so, all the horror stories about failed timing chain guides, excessive carbon on the intake valves, etc., spooked me into trading it in on a 2015 Fiesta ST. So yeah, what you found here simply bears out what the MINI Forum was talking about back then. Disappointing…
Great call. I'm sure trouble was only right around the corner.
Every time I watch one of these , l say to myself , how much more fucked up can they build stuff ? Let's see how difficult we can make this to work on ! Seems like all these engines and trans were made to fail because they have to complicate everything to the point where you can't fix it in the car ! Not just BMW !
They will continue engineering them to only last a set number of miles as long as people keep buying them, unfortunately. I guess the best thing we can do as mechanically-inclined individuals is educating others as to the games being played with their wallets.
Caught the upload JUST in time 😂
My wife’s mini cooper did the same thing. Ate up all the guides and plastic everywhere in the engine. What a piece of shit of a car.
German heartache and pain.
Usually my Sunday morning breakfast watch. Love the videos 👍👍
This sounds exactly like he is talking about a GM Engine Disaster.
I just wait on this guy. Love it
Oh hey it’s my engine
That turbo was like a Diddy party at 12:30- lots of friction, but no shaft play yet 😅
That's probably because they used lots of baby oil from Costco. 😂😅😂😅😂
The guides looked baked/brittle, and whose bright idea was it to eliminate a removeable timing cover? What a pain. 3k oci 4 me.
Full synthetic oil change!! 5 thousand miles!!!
Period!!
I do on my cars.
Late model cars.
I don’t care what is recommended.
I still have a 6.0 power stroke I drove , just today.
Non deleted, btw!!!
I don’t care what is suggested.
6.0 powerstroke is worst engine ever made in the world..
You thought someone in the comments section wants to know what you do? Funny stuff right there...
"The next first thing..." is my favorite Eric-ism
My 268hp N52 has 221k and runs great
I own one of the predecessors. An M52 that hit 425,000 miles yesterday.
M52’s are so good. I have one with 238k myself
These recommended light oils in these like 5W 20. Unlike those 10W 50's and 60's in many other engines and that narrow range promotes oil life. Loss of viscosity in those wide viscosity ranges is rapid. 7500 might be OK in this case but really, why not at 5K. Less probably for that 10 W 50 stuff.
My favorite engine. On your channel!!!
I’m also great full I don’t own one!!
Because of the popularity on your channel!!
So you’re a lefty.
Oh no!
Where did he say that?
30:55 "ANOTHER!" -Ray 🤣
37:25 YAY BANANA MISSILE! 🚀😁
Sarurday night has officially started! 👍🏼🚕🚗🚖🚘⛽
First upvote! "Coughing" no oil
Well in all fairness there was SOME oil. It was just 15,000 miles old and not quite enough to make it all the way back 😅 Don't think all those little timing guide pieces were helping flow either!
Did we see a clamp removed then a hose be cut?
BMW has not made a good car since the 2002Tii and 3.0cs, I am so glad I dont work on that junk anymore.
The e46's were great cars and engines..after 2006 I liked them.. but good stuff went away.
Love the Hockey reference!
N26 more like No 26
nice Lotus
FINALLY🎉😂
.. a*sload of Plastic in engines anymore .. 🙄
I will stay with my 2007 civi manual with 255,000,.
08 with 310000
And the manual 😊😊😊
Hey hey!
Im glad im blessed with the magical N52B25. Had only small problems with it. I mean the normal stuff like valvecovergasket and a coolinghose broke of. The most expensive thing i had to fix was an unhappy camgear.
Just a “gentle” tap to remove the front pulley using a sledgehammer!! Brilliant!! Gift that keeps on giving, but wait!! There’s MORE!! I drive a Mercedes Benz A180. It has a M270 engine. Turbocharged 1.6. According to the manufacturer, oil change intervals are every 10,000km, or 6250 miles. It has about 55,000 miles on it from new. I am the second owner of the car. It has great service history. Next service is in 5 1/2 months. I call BMW cars Bodgy Motor Works for good reason. In my working life, I fixed them as part of my job.
I know you're a big BMW guy, Eric but...I just can't. There seem to be too many of 'these' engines that are overcomplicated and underbuilt...ticking timebombs. Maybe if I drove one, I'd understand.
10:38 🤣
Man.. I sure let youtube keep running in the background and found myself actually listening to this BMW engine vid. Whelp, I am out. 4 mins in and not sure how I got here. LOL. Here's a comment and a like anyway for support for not being a political or news item ;) LOL. (needs a cat)
Good vid to relax too.
BuT cOoLaNt CoLoR iSnT aNy InDiCaToR. tHeY cAn MaKe ThOsE aNy CoLoR tHeY wAnT. REEEEEEE!
I seriously don't remeber what thread that dude was in but lol. 100% there are only so many coolant manufacturers, and they do indeed stick to one color per formula so folk who know have that indication when under the hood. Better not be purple in there 😂
Well eric , this was sad. I sold my 1995 325i convertible today. 236750 miles . Zero engine problems since new. Never ever failed me even once. 😂😂😂
Hey Eric,
1 out of 3 ain't bad.😂
Surprisingly good shape considering that pick-up. Wow.
5,000 mile intervals probably would have saved that engine for sure, not to mention, extended the life of the timing components.
Most of the ultra high epa efficiency engines all seem to hold a significantly greater amount of moisture producing increased sludge build-up no matter what manufacturer.
Glad you got some good parts in this one.🤙
All the hooha about wet belts but none about plastic timing guides.
All those wires, I removed a Holden 6 this week and there was around 6 wires to free it from the car. Then had the head and pan off in another 10 min. Original 47 y/o with near 30000km.
Those bores are oval at the top. No wonder it had no ring seal. That head had been cleaned recently,, putting abrasive into and engine always scares me.
Worked on quite a few of these. Problems I saw was fuel pump problems, charge pipes disintegrating, oil cooler leaks turbos and chain issues due to DI and long oil change intervals.
Hi Eric, thanks for your videos - it great to see the real technical details….even though it is frustrating for customers !
Just a comment to the newer german engines: here in Germany engine workshops complain about the crappy oil pumps with too low oil pressure in nearly all newer german cars - regardless if it is BMW, Mercedes or VW. There are some companies that use their own reinforced oil pumps with higher oil pressure when the engines are repaired.
In my opinion it’s a shame that something like this is necessary….
I just finished doing a timing chain on my Honda K24 and said to myself "gee, it might have been cheaper if they used all plastic chain guides"...thankfully Honda is smarter than that.
thanks for the vid sir - I just burns my butt that a company like BMW would make a string of decisions to put an owner in a situation like this. I work with a guy who has owned BMWs for 30 years and he's just fed up, never plans to buy another one, has a nice new Volvo now which he loves. And just FYI, I changed the oil in our two vehicles and dropped the used synthetic off at the recycler earlier today.
when I had a turbo charged engine I changed the oil every 3,000 miles. those turbos get really hot plus I use to drive it pretty hard.
Get rid of riming belts because they have to be serviced. Timing chains last for (almost) ever. Let's make sure the timing chain guides have a shorter service life than a belt with 3x as much labor.
16:30 look at how thin that timing chain guide plastic is.. that is obvious planned obsolescence. If I knew my guides were that thin in my engine, it would ruin my entire ownership and make me scared to death 24/7.
I find myself wondering for engines, or whole cars even, that have higher-than-expected failure modes how they passed QA/QC and whether or not there was any dissent in the engineering groups.
I hate 15k oil change intervals most manufacturers recommend changing the filter every 5k amd toping up oil but people never did because they weren't taught
Any engine (especially with a turbocharger) you are better off doing oil changes every 5,000 miles, even some Ford dealers are now telling customers to ignore the owners manual or oil change clock in the dash and get the oil and filter changed every 5,000 miles on their ecoboosts because the turbo's coke up the oil and can harden in the oil passages and cause a turbo or engine failure.
12:10 I will never understand how their marketing department got away with that. Oil doesn't last 15k.
That motor had more crunch than someone eating dry grape nuts .
😂🤠
Thank you for all you do to bring us these little gems of knowledge to us all !!
you rock , Eric
At least the oil filter housing is aluminum. Wish they kept that design in the modern BMW engines!
There should be a class action suit for the electric water pumps. Been a failure since inception.
Everytime I see a BMW commercial I start laughing I do not know why 🙄
Boy, my 328i with this motor sure ran good, glad I got rid of it before it became a problem!!!
I’ve heard that if you turn your hand around backwards and grasp your tool, you can make believe it’s not you. 😐
I love your videos. I love the banter. I have and never will touch an engine. So, I get to do this through you. You provide a wonderful service to old guys like you. Blessings to you
I could use that water pump! It would make a good self contained high volume low pressure tank circulation pump
Hate working on cars with these engines, I feel terrible even doing a brake job or mounting a set of tires because I worry that the timing guides are about to explode and the car is gonna end up back in my bay needing an engine after the customer just spent several hundred dollars on actual wear and tear items.
I would like you to do a gme 4t engine, alfa romeo or jeep, if you can find one that's blown up.
i had a 2015 with the N26 engine. not one single issue at all with mine. tuned it a bit, was smooth and super quiet. my ex wide had a 2012 of the same engine and she beat the snot out of it and it didnt have any issues either....poor maintanence etc.
Do BMW engineers get paid A Bonus for how many parts they can put into a 4 cylinder engine?
this motor is so trash. your buying a luxury car thats sounds like a broken sewing machine . what a joke
Thanks for the Saturday night entertainment Eric. Have a good weekend.
Boring night - but finally something I can relate to!
Fingers cross its a money maker! 😊
That’s a fact. You can’t compromise quality, ever.
Looks like it needed a timing chain service and pan/pickup service and it'd run again.
You should tear down a ford 460 big block next.
What's up Eric i stopped by your shop on Friday i spoke to your staff nice place
Much rather have a timing belt than a timing chain with these stupid plastic guides. I hate them.
As soon as the camera zoomed in I knew that coolant hose from pump was getting the chop chop
The pickup bolt appears to be either vomiting of wowed lol 😮
Lemme guess - timing chain guides caused a dropped valve 🙈
That thing has more copper in the wiring harnesses then an electric car 😮
SHOUT OUT TO ROBOT CANTINA FOR MENTIONING BLUE IN HIS LAST VIDEO.
It amazes me to see what crap car engines have turned into.
Eric, any M57 twin turbos coming?
Maybe we can get Diddy to do a PSA about engines needing oil
What does the "balance cartridge" do?
“It has some noise to it.” 😆🤣😂🥰
I thought I wanted a BMW at one time ???
Like 1974-5
Drove a 69 2002 in my 20s. Had some minor body damage when I bought it, so it was cheap.
Fun car and reliable.....
Your awesome 😊thx for all the videos
Love the teardown videos!
Time to stop by the barber college
You should do a Toyota 3mz-fe
Please do the 3rz-fe
10:46
I cannot unsee that 😜
Still awake to see video 👍
Thank you my fren.
Blue to the rescue!! 7:46
Cam Shaft and Snack Pak!
