This was clearly the unluckiest grandma in history. First, the engine blew up while she was idling out of the grocery store parking lot a mile from her house, then the battery caught fire in her driveway while she was calling the dealership to make arrangements for repair. Sad really, but I'm glad she's OK. Its a good thing she had insurance!
Hi Eric! I’m currently lying in bed recovering from back surgery and there isn’t much fun going on in my life right now. Except this channel. I hope you understand how your work brings joy to people. To some people it may just be broken engines. To me it’s a chance to hang out with a really cool guy while learning a lot of new things. Thanks for all you do!
Hope your back op is successful. Recovery is slowish with lots of physio. I paid for extra as I wasn't getting there very quickly. Look after you new back, it'll be geat but there are only so many surgeries you can have. I'm one ahead of you maybe. Good luck.
I hope you get well soon. I had a T-4 to L-5 spinal Fusion (about 3/4 of my spine) and yeah the surgery caused a blood clot in my right leg from my ankle to my knee (from a central, which is where they put a very large needle in your jugular and send the blood through a machine that filters and adds oxygen and then puts it back in your ankle) with a PE to my right lung (yeah i should be dead a couple of times over). I still have issues but at least I'm not three inches taller on my right side compared to my left. Anyway stay strong and remember it will get better. (physical therapy was full of good days and bad).
@@nigelalderman9178 Thanks! I'm 5 days post op and I'm already walking around in my house. Still some sciatic pain left, but my nerve has been grinding against the disc for a long time, so it probably takes some time to recover. Had L4-L5 and L5-S1 done.

idk man, some people can probably kill it in less time. If we get real lucky somebody will full send their car into a cement wall while texting and tiktoking and he might get the crumpled remains of that engine.
It should be right after they start selling cars with the straight 6 twin turbo engine. I've read that they're going to use powdered metal rods and cast pistons in the engine, and can we imagine what will happen when those parts are subjected to 20 psi turbo boost. 500+ HP out of a 180 cubic inch engine and with cast pistons and powdered metal rods.
Well, he didn’t have a dibstick to remove this time, so the engine had to give him something to fight. But if he really wanted to, he could definitely post that footage on his grindr profile
For the oil filter housing and oil cooler gaskets, the BMW design uses either an EPDM or BUNA-N rubber. A lot of the OE/OEM name brands offer a fluorosilicone rubber version now. That can potentially increase the seal life under high temperature. I've used it on my own repairs of that component.
The broken valve allowed the combustion to travel all the way down the exhaust where it found a hole leading to the trunk and the still burning combustion gasses caught the trunk carpet (and a spare container of gas) on fire. This is common on engines with horizontal valve springs. I think Ralph Nader wrote about it in his book "German Flamethrowers." I could be wrong though. I was wrong once before so it's possible I could be wrong again.
No no no, that's not it... it ate the valve just as it was preparing to auto stop the engine, and when it tried to re-start the engine to get going again, the engine locked, causing the starter draw while trying to break through the stopped engine to cause the battery to super heat and burst into flames. Yeah, that's it. (LOL)
@@aperson9495 I still think that gas can and a match had something to do with it. But yeah, I've heard those engines with horizontal valve springs tended to self delete themselves or ate parts of the adjustable valves. Top notch German engineering right there.
Dont be so negative, The old lady owner got such a fright when her trunk exploded in flames that she stepped on the gas so fast that the engine dropped a valve.
The design of the n54 belt is something to be aware of in all filet mignon situations. The power steering pulley get brittle and chip away after 100,000 miles, can also break where the bolts thread. Recommend changing, and locktighting the pulley or upgrading to metal that way you won't have to think about the belt slipping off and almost getting sucked into the crank seal. Had just done the oil filter gasket earlier that year but man I got incredibly lucky.
Cool video Eric. I wanna know what they did to booger up that crank snout. I've been watching so many of Rainman Ray's videos now that I was expecting "socket gravity" and the noise he plays when hosing things down with brake clean...
At some point about 20 years ago BMW decided that it would be a good idea to extend the service life of the engine oil based on some algorithms someone dreamed up. Our 2004 MINI Cooper when new was to go about 20K miles between oil changes according to the computer’s service interval read out. I heard stories of leased BMWs being sold as CPOs that blew the engines at about 80k miles because of oil sludge. On our MINI those long oil change interval “changed” (updated software?), but they are still 12-15k on our newer MINIs. A guess - this engine was one where the owner(s) followed the BMW display for service interval…. On a turbo car, that oil gets cooked. No good will happen following what BMW says. Great video!
I'm a long time viewer but first time commenter. Thanks for sharing your engine insight. I really enjoy your depth of knowledge regarding BMW engines. Thanks again.
Sad to see that someone bought this car, but really couldn't afford to properly maintain it; the end result is destruction! Boo to BMW for the oil leaks. Perhaps I am too naive to think that a highly engineered, supposed excellently designed engines wouldn't leak so as to cause these failures. As always, an excellent video, Eric! I love your channel.
I have had many Bimmers that never leaked... That engine leaked because someone got into it and did not put it back together correctly, and then it started leaking.. All German cars require a lot more maintenance than American cars... If one does not keep up with their maintenance schedule, then sometimes bad things happen... This engine had very few oil and filter changes, and perhaps they just ran the oil without ever checking the oil level for years... These in line 6 cylinder engines are really great, run super nice, and can get great mileage on the highway...And, they are really great driving cars, like their ad of years ago - "BMW the Ultimate Driving Machine".......... :)
The EXACT same thing happened to my E34 525i with the M20 engine, right after startup at idle, the engine stopped, i heard clunking, and it wouldn't spin over; when we took off the head we saw a valve was broken, it was also the exhaust valve, on cylinder 5. Luckily, the bore and the piston was okay and we just replaced the valve and it was all good; but I never found out WHY would someting like this happen.
One thing a lot of BMW owners don't understand is that many 'BMW mechanics' are only parts changers and that a number of BMW dealerships know this and just hope their 'mechanics' can keep the cars running until they're out of warranty.
It’s actually quite simple for a BMW engine. There’s no individual throttle bodies, no weird “valvetronic” nonsense, it’s easy to change coils, plugs and injectors with a bit of know-how. Not bad really, you just have to do the preventative maintenance.
@@TML34 I believe you. But mean just the look of that side of the engine. The aesthetic of the parts... they way it all looked. Sometimes things just affect me, and this reminds me of... something alien, or uncanny valley....
@@mediocreman2 I've been working on N54's since they came out. It's not rocket science. The only real challenging part is changing the turbos, but most of the day-to-day issues are all diy friendly.
Silicone restricted oil flow and the lack of maintence caused the valve guide to seize to the valve causing the valve to slap the piston and this unlocked the keepers dropping the valve until the piston broke the face of the valve and inturn locked the engine
I'm super surprised there aren't a bunch of folks suggesting this engine ingested the DISA flapper. This is a common thing for BMW, and one would think they could redesign the DISA, after a couple decades of failure. I actually heard mine being ingested, about gave me a heart attack, but evidently no damage and the engine ran another 100K until I sold it, still running solid.
My Aston Martin 4.7 V8 dropped an exhaust valve head and caused similar "malice in the combustion palace". When I turned it off it was still turning over. Have to assume the recovery company started it because it was seized on arrival at the garage (shop). The piston impacted the free valve head, cracked, tilted and cracked through the liner into two coolant jackets. The repair bill is utterly eye-watering but I love my Vantage so it will be reborn (rather than burnt). Rest assured, the remainder of the inside of my engine did not look like this one but is soon to be a coffee table.
On the subject of crappy repairs, earlier this week the yard I work for sold the 5.7 Hemi from a 2013 Ram 1500. The truck itself had 344000km on it, and truck ran quite well, however the engine itself had at least been apart to have the camshaft and lifters replaced as they are very failure prone on those engines. The truck wasn’t on its original transmission either as there was a stock number from another yard on the transmission. All of the previous work was very visible from all of the out of place, or simply absent bolts. But my favourite was the bellhousing, the late model Hemi uses the same or a very similar bolt pattern to many older Chrysler V8’s, including their use of SAE bolts in certain places as the 4 uppermost bellhousing bolts in a Hemi block are 3/8 by 16 threads per inch. The late model Hemi’s also use a cast aluminum brace on the bottom of the bellhousing which bolts to the block and transmission case entirely with metric bolts(M10 x 1.5mm) which are slightly larger then the SAE bolts on the top of the bellhousing. The previous “mechanic” took no notice of the visibly different bolts used the different locations and I believe tried to force one of the larger metric bolts into the hole for standard bolts and “installed” the extra SAE bolt in the lower brace with the larger metric bolt hole. With the block(and any threads cut in it) being cast iron the metric bolt made it 4 or 5 threads into the SAE bolt hole destroying the threads in the block as it went before breaking off in the block. As this bolt was broken off on its way in because it was wrong for the hole, removing it with the welder or an easy out was never going to happen, the remains of the bolt were removed with a die grinder, a carbide burr, and a tap, and the block got a heli-coil.
It just goes to show you more moving parts, the more ways for an engine to brake down. I repaired a straight 6 72 Ford engine with no experience other than a book, now with the added technology on engines today my experience only works on lawnmower engines today.
Great teardown, as always. However, many of your intros tease us with the Series 3 RX-7 on the rack in the background. I share your affinity for 80’s Mazdas as I grew up with an ‘80 626 coupe (same color as yours), an ‘84 RX-7, and an ‘87 RX-7 Turbo that forever endeared me to the brand. Always loved telling curious minds why RX’s burned oil on purpose! Please give us a tour at your convenience!
Two notes about the oil filter housing: - also order the housing bolts just in case because sometimes they break. I had one snap and crack the housing near the threads and had to replace the entire thing - Sometimes the intake has to come off, however, if you just loosen/remove all the bolts, you can wiggle it aside to get to the last bolt and get it in and out with a swivel. Locking extensions/locking swivels will help a lot with the last bolt by the intake
If you do the oil filter housing gasket yourself, make sure you bleed the oil circuit by removing the plugs for the coils and cranking the engine 3 times for 10 seconds with 20 seconds between each crank. If this isn't done, you run the risk of scoring your camshafts and the journals. Source: Me, Dealer tech
Back in the 80's I worked in the fire brigade in Sydney. We had so many cars "stolen" and burned in the end, the insurance companies refused to pay any and all those claims. That stopped it!
When I worked at Kaunz in Lake Forest, Illinois I bought a 2002 tii that came in as a trade. it was a good runner but a little tired. And bought my wife a BMW 320 i S. It came in with about 3,000 miles on it when I bought it. Kept it for about 80,000. Never broke. Don't know why it held together so well.
Another great tear down. Thanks for showing the VIN. I hope this is acted on & results in prosecutor. We all end up paying, through increased insurance costs, for thieving scammers who don’t change their oil.
They will never prove it,I been paying insurance on house, boats and vehicles for 40years and had about two small claims,but premiums never get cheaper...
Yea i called it the moment i seen the RTV over the crank seal. The belt got sucked into the front main seal after it snapped "hence the RTV" and instead of pulling the old broken seal out and ensuring there was no belt left in the motor, he decided to put RTV around the seal and called it a day. This all could have been avoided with a 40$ seal. Went from a 200$ job to a 4000+$ job. It's clear this man/kid just wanted a 335i with little to no cash. Poor thing couldn't even get fresh oil on time. I have done the job at least twice and had it even happen to my car. Luckily, my motor survived. Just a tip for anyone, buy yourself a belt guard from ECSTuning for peace of mind. It's cheap and can save you a massive head ache.
@@zachansen8293 Coming from a automotive Tech they really dont. They just decline it if they think its fishy but iv seen people do blatant insurance fraud and it gets paid 🤷🏿♂️

Very interesting. I had my 335is injectors replaced recently with new, original ones and I wish I would have known about your stock. Man, they were expensive 😵
I’ve owned & sold many BMW’s (owned a dealership). While maintenance is important there is also driver behavior. Driving gently can greatly reduce problems but BMW owners tend to drive with a lot of spirit. My 176K Toyota RAV4 and 406K LandCruiser rarely hits above 3K rpm.
If you’re trying to cut the cord you could grab a Milwaukee High Torque for those tougher bolts. Close to 800 ft lbs breakaway so about three times the little subcompact. Love that little guy though.
The vanos oil filters are located near the chain tensioner, two recessed plugs T40 or something. Remove those if you want to find debris. Goes for all (bmw, mini) engines that have solenoids without screens directly on them. They are made from aluminium, so don't use an impact gun on them.
Long ago a car had to be smashed to bits to get totalled, now it can be totalled for mechanical issues costing more that it's worth to repair. Incredible!
You really messed with my head @ 38:21 when you had the bed plate sitting on top the cylinder head. It took a couple seconds for my brain to realize it.
I know you are a BMW Guy, but MAN Do these, and any BMW engine look to be stupid levels of Complicated. and this is coming from a Lincoln LS owner, That Jaguar V8 has its quirks yes, But they seem simple compared to this, or any BMW engine really. Except for the OLD 90s 4.0 V8s that he AJ takes Inspiration from. Those seem somewhat simpler.
Honestly there isn't much more that it has compared to your V8. Just direct injection and a turbo system. Other than that it's almost all the same basic stuff. It's just alot crammed into a small package
All modern auto manufacturers are out competing with each other to make the most overcomplicated and finicky plastic shit. All to appease marketing departments and consumers who are more qualified to hold opinions on white goods products. The logic and reasoning is based on aspirational outcomes that have no value beyond their fantastic imagination.
@@AlienLivesMatter no. They are worried about production cost and warranty period reliability. That's it all they care about because that's all stock holders care about. Whatever affects bottom line and drives sales. Nothing you said would help in either way. Always assume cost saving during production over malice when it comes to the engineering issues that come up during repair
I agree, it seems the German manufacturers look for ways to, not the right term but, over engineer, their products. Resulting in an expensive to buy and maintain product. The VW engine recently featured on this channel that had an inaccessible plastic water pump just that is known to have a high failure rate keeps me buying Japanese products.
improper oil changes is sure a way to induce excessive valve float, and then it just takes one little tap for the valve to stop sitting straight and eventually get crushed along with a sudden loss of turbo boost. Either that or belt material caused the same process, or even just too much soot gunk. While working at a head shop ive seen quite a few instances of valves just not wanting to move freely in the guides, or they might move partially but the top has been mushroomed from excess pressure, having to grind the top down so that they can be removed without destroying the guide completely. If the service manual states a specific oil type with specific change intervals, you follow them. If it also states carbon cleaning you get that done. Best case for the latter is it just refusing to turn over in the morning, you cant make diamonds with an engine block.
Valves sometimes crack. Also if they ever overheat the valve seats may start to drop out of the cylinder head. Bottom ends are pretty good as long as the oil is changed and kept full. They do burn oil.
Bmw updated the coolant in 2018 iirc from blue to green. The blue isn't forward compatible but the green coolant is backward compatible. It is entirely possible that if the water pump had been replaced at any point after 2018 that it could've been refilled with the bmw green coolant.
Lot's of smart, knowlegable info on this one. guess I don't want to be a BMW tech in my next life! Never heard of aluminium bolts. watched this is full screen, fun!
There's a slide hammer tool kit you can buy for removing the injectors on the 3.2L straight six that was in the 2005 E320 CDI and I think that would help you out a lot. That one gives a decent amount of room for the slide hammer.

@@aperson9495 I still think that gas can and a match had something to do with it. But yeah, I've heard those engines with horizontal valve springs tended to self delete themselves or ate parts of the adjustable valves.
Top notch German engineering right there.
Dont be so negative, The old lady owner got such a fright when her trunk exploded in flames that she stepped on the gas so fast that the engine dropped a valve.
The design of the n54 belt is something to be aware of in all filet mignon situations. The power steering pulley get brittle and chip away after 100,000 miles, can also break where the bolts thread. Recommend changing, and locktighting the pulley or upgrading to metal that way you won't have to think about the belt slipping off and almost getting sucked into the crank seal. Had just done the oil filter gasket earlier that year but man I got incredibly lucky.
Honestly Really impressed with that piston holding together with a valve rattling around
Did you get a new mic recently? Those head bolt cracks were sounding extra crispy lol....thanks for another great teardown!
Hi Eric, I thank you very much for putting the subtitles back.
Greetings from Barcelona, Spain.
Cool video Eric. I wanna know what they did to booger up that crank snout. I've been watching so many of Rainman Ray's videos now that I was expecting "socket gravity" and the noise he plays when hosing things down with brake clean...

Yep plus 1
At some point about 20 years ago BMW decided that it would be a good idea to extend the service life of the engine oil based on some algorithms someone dreamed up. Our 2004 MINI Cooper when new was to go about 20K miles between oil changes according to the computer’s service interval read out. I heard stories of leased BMWs being sold as CPOs that blew the engines at about 80k miles because of oil sludge. On our MINI those long oil change interval “changed” (updated software?), but they are still 12-15k on our newer MINIs. A guess - this engine was one where the owner(s) followed the BMW display for service interval…. On a turbo car, that oil gets cooked. No good will happen following what BMW says.
Great video!
"in and out shaft play" made my fn night.
Dang, 42 years in the automotive business for me. And 10 years on TH-cam alone. Great video again.
Great high definition camera work. Super interesting. Unleashing the Kraken ! (flashing the VIN) :)
I'm a long time viewer but first time commenter. Thanks for sharing your engine insight. I really enjoy your depth of knowledge regarding BMW engines. Thanks again.
Sad to see that someone bought this car, but really couldn't afford to properly maintain it; the end result is destruction! Boo to BMW for the oil leaks. Perhaps I am too naive to think that a highly engineered, supposed excellently designed engines wouldn't leak so as to cause these failures. As always, an excellent video, Eric! I love your channel.
I have had many Bimmers that never leaked... That engine leaked because someone got into it and did not put it back together correctly, and then it started leaking.. All German cars require a lot more maintenance than American cars... If one does not keep up with their maintenance schedule, then sometimes bad things happen... This engine had very few oil and filter changes, and perhaps they just ran the oil without ever checking the oil level for years... These in line 6 cylinder engines are really great, run super nice, and can get great mileage on the highway...And, they are really great driving cars, like their ad of years ago - "BMW the Ultimate Driving Machine".......... :)
The EXACT same thing happened to my E34 525i with the M20 engine, right after startup at idle, the engine stopped, i heard clunking, and it wouldn't spin over; when we took off the head we saw a valve was broken, it was also the exhaust valve, on cylinder 5. Luckily, the bore and the piston was okay and we just replaced the valve and it was all good; but I never found out WHY would someting like this happen.
Next time you have to pull injectors, trying twisting as you stroke up and down. Usually helps get the job done a little quicker.
You so nasty!
😂😂
One thing a lot of BMW owners don't understand is that many 'BMW mechanics' are only parts changers and that a number of BMW dealerships know this and just hope their 'mechanics' can keep the cars running until they're out of warranty.
I've worked on and taken apart various engines... but for some reason, this engine ... sort of gives me the willies.
It’s actually quite simple for a BMW engine. There’s no individual throttle bodies, no weird “valvetronic” nonsense, it’s easy to change coils, plugs and injectors with a bit of know-how. Not bad really, you just have to do the preventative maintenance.
its a BMW thing lol. Some people love them, then there are other people like me that use logic and say, "hell no" that thing is my nightmare
@@TML34 I believe you. But mean just the look of that side of the engine. The aesthetic of the parts... they way it all looked. Sometimes things just affect me, and this reminds me of... something alien, or uncanny valley....
This is not 'quite simple' for a BMW engine lol. It's one of the worst. If you want simple, but still modern, look at N52.
@@mediocreman2 I've been working on N54's since they came out. It's not rocket science. The only real challenging part is changing the turbos, but most of the day-to-day issues are all diy friendly.
Silicone restricted oil flow and the lack of maintence caused the valve guide to seize to the valve causing the valve to slap the piston and this unlocked the keepers dropping the valve until the piston broke the face of the valve and inturn locked the engine
great vid man, i always look forward to you posting!
I'm super surprised there aren't a bunch of folks suggesting this engine ingested the DISA flapper. This is a common thing for BMW, and one would think they could redesign the DISA, after a couple decades of failure. I actually heard mine being ingested, about gave me a heart attack, but evidently no damage and the engine ran another 100K until I sold it, still running solid.
Eric, be gentle with the injector, if you jiggle it too hard it will start leaking way too soon.
SMASH!!! That timing cassette didn't stand a chance. Great teardown Eric!

My Aston Martin 4.7 V8 dropped an exhaust valve head and caused similar "malice in the combustion palace". When I turned it off it was still turning over. Have to assume the recovery company started it because it was seized on arrival at the garage (shop). The piston impacted the free valve head, cracked, tilted and cracked through the liner into two coolant jackets. The repair bill is utterly eye-watering but I love my Vantage so it will be reborn (rather than burnt). Rest assured, the remainder of the inside of my engine did not look like this one but is soon to be a coffee table.
On the subject of crappy repairs, earlier this week the yard I work for sold the 5.7 Hemi from a 2013 Ram 1500. The truck itself had 344000km on it, and truck ran quite well, however the engine itself had at least been apart to have the camshaft and lifters replaced as they are very failure prone on those engines. The truck wasn’t on its original transmission either as there was a stock number from another yard on the transmission. All of the previous work was very visible from all of the out of place, or simply absent bolts.
But my favourite was the bellhousing, the late model Hemi uses the same or a very similar bolt pattern to many older Chrysler V8’s, including their use of SAE bolts in certain places as the 4 uppermost bellhousing bolts in a Hemi block are 3/8 by 16 threads per inch. The late model Hemi’s also use a cast aluminum brace on the bottom of the bellhousing which bolts to the block and transmission case entirely with metric bolts(M10 x 1.5mm) which are slightly larger then the SAE bolts on the top of the bellhousing. The previous “mechanic” took no notice of the visibly different bolts used the different locations and I believe tried to force one of the larger metric bolts into the hole for standard bolts and “installed” the extra SAE bolt in the lower brace with the larger metric bolt hole. With the block(and any threads cut in it) being cast iron the metric bolt made it 4 or 5 threads into the SAE bolt hole destroying the threads in the block as it went before breaking off in the block. As this bolt was broken off on its way in because it was wrong for the hole, removing it with the welder or an easy out was never going to happen, the remains of the bolt were removed with a die grinder, a carbide burr, and a tap, and the block got a heli-coil.
Ugh. I hate that. We see this stuff often too. Cars are already unreliable enough, they don’t need people’s help to make them worse 😂
It just goes to show you more moving parts, the more ways for an engine to brake down.
I repaired a straight 6 72 Ford engine with no experience other than a book, now with the added technology on engines today my experience only works on lawnmower engines today.
Awesome videos, will we see any early 2000s bmw 540i 4.4l teardowns? Keep up the awesomeness.
Great teardown, as always. However, many of your intros tease us with the Series 3 RX-7 on the rack in the background. I share your affinity for 80’s Mazdas as I grew up with an ‘80 626 coupe (same color as yours), an ‘84 RX-7, and an ‘87 RX-7 Turbo that forever endeared me to the brand. Always loved telling curious minds why RX’s burned oil on purpose! Please give us a tour at your convenience!
Two notes about the oil filter housing:
- also order the housing bolts just in case because sometimes they break. I had one snap and crack the housing near the threads and had to replace the entire thing
- Sometimes the intake has to come off, however, if you just loosen/remove all the bolts, you can wiggle it aside to get to the last bolt and get it in and out with a swivel.
Locking extensions/locking swivels will help a lot with the last bolt by the intake
Loved the slow motion destruction of the timing guides. Keep up the great work!
If you do the oil filter housing gasket yourself, make sure you bleed the oil circuit by removing the plugs for the coils and cranking the engine 3 times for 10 seconds with 20 seconds between each crank. If this isn't done, you run the risk of scoring your camshafts and the journals.
Source: Me, Dealer tech
Why is that ? Seems like all that would do is remove residual oil in housing
@@drifter9425 the n52/n54/n55 had trouble getting oil to the head after ofhg replacement for some reason, and that scored the journals / trays.
Bmw won't pay the labor for that on a warranty repair...

We all end up paying, through increased insurance costs, for thieving scammers who don’t change their oil.
You pay because insurance is highly profitable
They will never prove it,I been paying insurance on house, boats and vehicles for 40years and had about two small claims,but premiums never get cheaper...
no rational insurance company is going to pursue this tiny loss this far after the fact
You pay through the nose for their giant profits not the odd fake claim lol
Spiking the timing guide on the floor was the most Epic moment I have seen in any of you videos! Please keep it going! Amazing!!
Great video as usual! Always love seeing different manufacturers and engines. If yea get a shot would love to see the giant V4 2.7 gm if yea find one!

@@trentryan27aren't they in Chevy and GMC 1500s should make them fairly common?
@@DH-mw5rz yeah its a I-4 and its a fairly new engine option
Yea i called it the moment i seen the RTV over the crank seal. The belt got sucked into the front main seal after it snapped "hence the RTV" and instead of pulling the old broken seal out and ensuring there was no belt left in the motor, he decided to put RTV around the seal and called it a day. This all could have been avoided with a 40$ seal. Went from a 200$ job to a 4000+$ job. It's clear this man/kid just wanted a 335i with little to no cash. Poor thing couldn't even get fresh oil on time. I have done the job at least twice and had it even happen to my car. Luckily, my motor survived. Just a tip for anyone, buy yourself a belt guard from ECSTuning for peace of mind. It's cheap and can save you a massive head ache.
The fire in the boot clearly broke that valve. Happens all the time.
2:20 I had to pause the video. The black lift blended into the background. It looked like the pickup truck was sitting on the shelf.
Thank goodness the N54 doesn't have a particularly shaped water pump to go along with the injector stroking we got.
I love these autopsy videos, it really is like watching a coroner at work as he dissects the patient, looking for a cause of death.

Very interesting. I had my 335is injectors replaced recently with new, original ones and I wish I would have known about your stock. Man, they were expensive 😵
I’ve owned & sold many BMW’s (owned a dealership). While maintenance is important there is also driver behavior. Driving gently can greatly reduce problems but BMW owners tend to drive with a lot of spirit. My 176K Toyota RAV4 and 406K LandCruiser rarely hits above 3K rpm.

If you’re trying to cut the cord you could grab a Milwaukee High Torque for those tougher bolts. Close to 800 ft lbs breakaway so about three times the little subcompact. Love that little guy though.
Turns over just dandy once you get the valve pieces out of the cylinder
The vanos oil filters are located near the chain tensioner, two recessed plugs T40 or something. Remove those if you want to find debris. Goes for all (bmw, mini) engines that have solenoids without screens directly on them. They are made from aluminium, so don't use an impact gun on them.
Cant wait to see this teardown (only 2 minutes into it)
Long ago a car had to be smashed to bits to get totalled, now it can be totalled for mechanical issues
costing more that it's worth to repair. Incredible!
That wrist action with the injector removal tool looks strangely familiar for some reason. I can't quite place where I've seen that motion before.

its a slide hammer. thats just how you use the thing. beat it like it owes you money

This is my absolute favorite TH-cam channel. Thanks a lot for posting these videos.
I know you are a BMW Guy, but MAN Do these, and any BMW engine look to be stupid levels of Complicated. and this is coming from a Lincoln LS owner, That Jaguar V8 has its quirks yes, But they seem simple compared to this, or any BMW engine really. Except for the OLD 90s 4.0 V8s that he AJ takes Inspiration from. Those seem somewhat simpler.
Honestly there isn't much more that it has compared to your V8. Just direct injection and a turbo system. Other than that it's almost all the same basic stuff.
It's just alot crammed into a small package
Go watch an Audi V6 or V8 tear down.
All modern auto manufacturers are out competing with each other to make the most overcomplicated and finicky plastic shit.
All to appease marketing departments and consumers who are more qualified to hold opinions on white goods products.
The logic and reasoning is based on aspirational outcomes that have no value beyond their fantastic imagination.
@@AlienLivesMatter no. They are worried about production cost and warranty period reliability. That's it all they care about because that's all stock holders care about. Whatever affects bottom line and drives sales. Nothing you said would help in either way. Always assume cost saving during production over malice when it comes to the engineering issues that come up during repair
I agree, it seems the German manufacturers look for ways to, not the right term but, over engineer, their products. Resulting in an expensive to buy and maintain product. The VW engine recently featured on this channel that had an inaccessible plastic water pump just that is known to have a high failure rate keeps me buying Japanese products.
Nice work with the slide hammer! You must use that a lot.
Love your channel, keep up the good work!!
"I can fix this crank seal, hold my beer"----proceeds to get out 2 lb mallet and chisel
Yay my Saturday night is complete. Another engine tear down.
Say it again! Insurance job!
@13:30 Way to stroke that stuck injector out. Looks like you've had practice doing that.
Eric, watching you work the injectors out was amazing 🤣
jinjer friend!
improper oil changes is sure a way to induce excessive valve float, and then it just takes one little tap for the valve to stop sitting straight and eventually get crushed along with a sudden loss of turbo boost. Either that or belt material caused the same process, or even just too much soot gunk.
While working at a head shop ive seen quite a few instances of valves just not wanting to move freely in the guides, or they might move partially but the top has been mushroomed from excess pressure, having to grind the top down so that they can be removed without destroying the guide completely.
If the service manual states a specific oil type with specific change intervals, you follow them. If it also states carbon cleaning you get that done. Best case for the latter is it just refusing to turn over in the morning, you cant make diamonds with an engine block.
Do you deal in Mini Coopers? How about N14 or N18 engines? They're notoriously reliable. Would be near impossible to find a failed motor.
Valves sometimes crack. Also if they ever overheat the valve seats may start to drop out of the cylinder head. Bottom ends are pretty good as long as the oil is changed and kept full. They do burn oil.
Bmw updated the coolant in 2018 iirc from blue to green. The blue isn't forward compatible but the green coolant is backward compatible. It is entirely possible that if the water pump had been replaced at any point after 2018 that it could've been refilled with the bmw green coolant.
a blown engine and a trunk fire at the same time. nothing sus about that! drats he only had 15 payments left
Lot's of smart, knowlegable info on this one. guess I don't want to be a BMW tech in my next life!
Never heard of aluminium bolts. watched this is full screen, fun!
Can you do a tear down off a blown up ford 300 i6 if you can find one
Anyone with a Ford 300 is probably smart enough to keep it and rebuild it.
Hmmm. I have a 2009 335i that a turbo just went bad on. I think my battery is getting really HOT now too in the trunk!
It could have been yellow coolant mixed with the blue.
There's a slide hammer tool kit you can buy for removing the injectors on the 3.2L straight six that was in the 2005 E320 CDI and I think that would help you out a lot. That one gives a decent amount of room for the slide hammer.
