I'm physically hurting over here for you. I'm so sorry dude.
Thanks, Alex! She'll be fixed and on the road by the time you come to visit!
Can't wait to see you guys working together.
Can both of y’all please do a collab on merch! It’d be epic!!
Both Alex and Sreten are my favorite youtubers
Seems like the B7 and Cl65 are behaving in similar ways
Can we just appreciate that he uploaded a Instagram post 4 days ago where the engine was removed and now there's a high quality video of it ALREADY??? You're insane bud!
Thank you!
@@M539Restorations prilikom obrade cilindara treba metalna ploca koja se steze umesto glave,jer cilindri se deformisu prilikom stezanja .Ne bas toliko ali ipak malo.Cini mi se da je taj "majstor" zbrzao posao prilikom obrade ,plus mu je masina koja vrsi obradu neispravna cim toliki oval pravi.I jos nije ni izmerio kada je zavrsio posao jer bi video odstupanja kao i vi.Izbegavati ga ubuduce.

You don't know why you included drunk guy and yet it makes so much sense to help us understand the everyday life of a DIY guy in his shed...Thanks for that! :)
You have to put back the nail in the oil pan. Its just some weird kind of counterweight which will counter vibrations which otherwise will cause the zylinders to wear heavily.
lmfao
Lmao😂😂
The so called COUNTER NAIL 😅
You genius
This must be the most frustrating disassembly of all times, but spirit is up which is nice. Hope it plays out well.
The mighty intercooler though :D
Noyan chief doesn't miss any detail like usual. :D
He gets paid either way, in or out. All good.
He can do everything! I believe! :D
@T H While you're not wrong, remember this whole project build is supposed to keep the cost down. Therefore, not much new parts being used and mostly refurbished. Otherwise he could've bought everything new down to the bolts and kinda no point for doing this whole video.
I’ve been building large Audi engines of various types & VW engines also for 24 years & am factory trained/certified with both marques at main dealer level. I’ve observed your working practices & I can tell you that there are master technicians out there that aren’t as polished as you, your ability to remain calm in the face of adversity speaks volumes. You should be incredibly proud of how far you’ve come, stuff like this happens especially when relying on outside vendors. It’s very disheartening going over your own work knowing that it isn’t your fault, I’ve been there ! Keep your chin up & don’t doubt yourself… Tom, VW/Audi Technician 🏴.
Well said
What is an audi tech doing on a BMW channel 😂😉
Thanks a lot, Tom! Appreciate it.
Well said,the work is thorough and can’t be faulted,it’s unfortunate now you need to be learn how to check a machinists work over but that’s the edge it takes to prevent another failure. Great work as always ,and what about Dominic,did you call him or what?? 😂
Could that block be resleeved in your expert opinion ,or rebored to save it ?
my favorite line -> "it's not your fault, but it's your problem"
that was really good commentary on the cylinder clearances for dissimilar metals
Dude, so sorry this happened. I admire your dedication to keep going. 💪

"It's not your fault but it is your problem", that machinist was hilarious! That was the perfect response from a guy who works in exact measurement and has no concept of 'grey areas'.

Thats deutsch humour, that one. First time I came across Sretens video, I was buffeld with his nationality. Produced in Deutschland, language unpolished English, precision work at its finest, has jokes that work (video, not Sreten).
Sreten, you teach us all to never give up even when things look bleak. This is a labor of love, and you show it. Keep up the good work, this B7 will soon run again!
Like you said, anything can be fixed. Passion and dedication can fix anything, keep it up!
@@DeadEndRestorations don't forget the bundle of cash it takes to do it right
Bad decision, don't buy used BMW engine (no bueno) 😉
This is a great point: I would have walked away LONG ago! Such impressive tenacity 🙌 Also, I love your game plan 😊
I had hit my head to the wall, almost literally for trying to understand why would anyone with such skills and intelligence start a project with E65. Sorry,but it's beyond suicide. Everything in that car is flawed by default. It's not beautiful either. I would've gone with E38 B12 ( if Alpina is the one to go) and enjoy timeless, beautiful and magnificent solidly built car.
Ladies and gents we are witnessing the most patient master mechanic in the world. Thank you Sreten, keep up the great work 👍
Yeah his dedication is unbelievable... i would have part it out already
You’re not kidding. I just started watching this playlist. My anger level was just so high on his behalf.
Like we say in Greece “paint it blue and throw it in the sea”
Love your show - it scratches an itch in a strange part of my brain. Keep doing what you’re doing brotha
Like living vicariously through him. He does what I dream of being able to do; buying cool older unloved cars and bringing them back to life. I have an E90 which needs some work here and there, but as it turns out, cheap parts add up REAL quick.
Lovely work! stumbled on your videos and got hooked!I am restoring a 1988 W124 myself.Its not rocket science if you read manual,watch videos like yours and have a leaning towards tools and machines.Great work! Greetings from Nairobi!

The egg shape is caused by the internal structure of the piston. Inside the piston is the support structure for the pistonpen. This is the item that is in the direction of the widest form of the eggshaped cylinder. The overheating pistonpen expands in his lateral direction and gives pressure on the cylinder wall. That’s why the cylinders have a wider shape there. The 90 degrees sides endured no pressure from these pens and because they have no structural support in that direction, they don’t scratch that side of the cylinder wall. The expanding pistons expand in the direction of where they are strongest and contain therefore the most thermal energy. The fluctuation of the roundness at extreme temperatures normally is compensated by the width of the free floating piston rings. An ideal piston has to stay a perfect circle all the way from warming up to extreme temperatures. If not enough clearance is taken in account with the opposing cylinder wall of a different metal (having a different expansion rate under temperature), the most resistance is in the direction of the piston pens and there you see the wear and the egg shape of the wall
The drunk guy was amazing!! Well handled ! 👏👏👏
Did the drunk guy say he murdered his wife? 😱
Some thoughts. The block is cast aluminium (not forged I assume) and the sleeves should be austenitic cast iron which has a higher coefficient of expansion that other types of cast iron. The bores could well have been in specification after pressing in the sleeves, boring and honing to size but went out of round and cylindricity after thermal cycling. If the sleeves have dropped in the bores that tells me that they do not have a locating step at the top which I would always do so they can neither move up nor down due to piston drag.
When I rebore engines I choose to lap to size not hone though honing is the industry practice. These engines I rebore are tiny compared to automotive engines. The reason I choose to lap not hone to size is that honing will not necessarily remove ovality in the bore, but lapping will and does. Ringed engines must have truly cylindrical bores and no taper permitted. Bore ovality leads to gas leaks and burning of piston and ring surfaces and bore taper to cyclic expansion and contraction of the rings with each stroke leading to piston ring gap wear and ring fatigue failure.
The dial indicator device your Machinist used is one way of measuring bores but does rely on both Operator skill and repeatability of the dial indicator. A more accurate and consistent method is to use a tri lobed bore micrometer made by Mitutoyo as their Intrimik series and also the Swiss. The tri lobed micrometer I use measures to 0.0001", necessary for my work. Tri lobed micrometers will not detect lobing of the bore caused by the initial boring or grinding operation and to detect that needs a temperature controlled laboratory with a Coordinate Measuring Machine costing hundreds of thousands of dollars.
Congratulations on your dedication to meticulous assembly and absolute persistence in determining the cause of the Alpina's B7's engine failure.
Just been reading up on Austenitic iron - interesting stuff!
Jay Leno and crew had a nightmare time trying to replace a cast iron piston with an aluminium one in one of his ancient motorbikes. In the end it was trial and error, going down in size until they found a size that worked. I'm a bit worried that Sreten might end up having to do the same with this one, especially if sleeves are going to change shape due to thermal cycling.
I second your point about a locating step. Seems to be important!
Hey Jon thanks for that...thats super helpful...tho Car Service...the guy with the Dial gauge...yes it should have been on a stand ...However, that cursory inspection of the block showed Sreten exactly what he needed to know....It wasn't Him, those measurements were way way off...and that wasn't due to mishandling of the Dial gauge. that was the bores being out.
Is there a way of thermal cycling the engine without starting and running the engine?
Just had engine problem local mechanic, an independent BMW technician, could not get hold of the repair manual for mazda. Autodata did not have information. Car goes to main dealer fixed same day, known fault with copper washers used in the fuel injectors. i remember the Alpina tech laughed when he said he was doing the engine rebuilt himself.
@@danstewart8218 I'd say watching the Machinist using the single axis bore gauge that he knew exactly how to use it. He also knew what typical piston clearance should be in the bores.
It also may well be that a BMW super charged V8 engine should have more piston clearance than a normally aspirated one as well. A greater mass of inlet charge due to supercharging must bring more heat. Wonder if the water pump is a greater flow on the B7? Wonder if the radiator is of greater capacity?
@@jcoul1sc Yes, a Heat Treatment facility would be able to place the sleeved block in an oven and thermal cycle it. When sleeves are pressed into engine blocks a hoop tension is created in each aluminium bore and the sleeve goes into compressive hoop stress. As cast iron and aluminium alloy have different coefficients of thermal expansion the stress values will rise and fall with each thermal cycle. The engine Design Engineer's and Engine Reconditioner's expectation would be that there would be no permanent movement in the bores geometry with in-service thermal cycling. I would expect BMW Engineers to verify that during the engine's design and development cycle.
Gotta join patreon, keep this mad man going. Who's with me
I love this guy, even after this major problem with the engine he still wants to complete the project. Bravo ! Looking forward to the next episode.

Episode was "Peak Performance" if I remember correctly.
The engine strip down in 5 hrs was impressive. You could work for Alpina any day.

Sreten, my heart weeps, but your perseverance is beyond admirable, and your community thanks you for continuing to produce content in spite of such incredible setbacks! As always we root for your continuing success!!
the fact that you can remain so calm tearing apart that engine after all the time and money you put into getting it running again is impressive.
From the measurements I saw, you could hone those cylinders to spec and make them round- you would need to skim the block to get the sleeves flush. We always left a sleeved block to "rest" for a day because sleeves would compress when pressed in and grow back a bit and rise above the surface. My guess is that they froze the sleeves with liquid nitrogen to drop them in and that shrunk them enough to drop slightly below the surface and as they thawed, the grip on the block prevented them from expanding upwards, but the material had to go somewhere, so they expanded and became egg shaped. BTW, the crazy guy who showed up in your shop chose the wrong day, he's lucky he got out unscathed.
i think you are right about the sleeves expanded, and that's why the egg shaped cylinder bore. But who could have guessed that they would become egg shaped.. really odd. Or could it have been prevented with a different kind of sleeve material? who knows.. :)
And to you Sreten, i admire your positive attitude!! You will fix this grumpy old Alpina! Me myself, i would have completely lost it ;)
That sounds like a really possible solution to me.
While this might be true for normal metals used in blocks, these engines are of course exotic and the difference in metals probably makes sleeving them a very challenging affair. To me, it seems like even if you did hone the cylinders to be flawless, they'd just warp the next time the engine got up to operating temp. I get that the e39 block did well, but sleeving a block with a different metal just seems like a recipe for disaster regardless
I have to agree. The frozen sleeves can also have been installed with the block at room temperature... this typical block should have been "heated" up. So, they most likely did not measure the sleeve internal radius after installing with the appropriate tool like the one at 28:25 or better a laser radius measuring.
Impressive info/conversation
"It's not your fault, but it is your porblem" what a great expression!
Of course it still sucks that this happens, but it's a great learning experience.
Can't wait to see more content on this car, good luck Sreten!
That felt like the most German joke ever. I loved it.
@@tass2001 Schadenfreude at its best 😁
Typical German bluntness. It's harsh but fair.
@@ssenssel It's not really Schadenfreude. He wasn't happy that that happened to Sreten. He was just putting things how they are. Very german.
Where he said that?
"It's not your fault. But it is your problem." - as a longtime BMW owner I must say, there is great wisdom in those words.
It is the right decision to acquire the used engine. The original work on the block was bogus. The guy appears to be incompetent. Even if he takes responsibility and "makes the correction", the pedigree is set. I have a saying that proves true time and time again; "Trouble in the beginning, trouble along the way, trouble in the end". We can also look at it from the perspective that the engine is "jinxed". See above saying. By swapping to the "new" used engine, you avoid the jinxed-ness of the original engine. I once bought a crashed motorcycle and rebuilt it only to ride into a car door head first at 60 kph. She "didn't see me". I am lucky to be alive. Jinxed in the beginning, jinxed along the way, jinxed in the end". At some point... luck runs out. Love the channel Sreten. Great content. Keep up the good work my Friend.
Man… this episode was heartbreaking, but it also underlines why we love this channel so much. Keep doing what you're doing.
It was hilarious adding the drunk intruder in the video but overall heartbreaking, I hope you get a result with the engine that's coming from Poland.
Usually a car from a breaker's yard didnt end up there because it was good.
But lets hope at least the block will not be worn out.
@@dan_6915 it can be an accident damaged (totaled) car that still has a good block.
@@tonyus8197
Depends of the accident.
These engines are like a swiss watch.
If you deprived them of oil for one minute or 2, it's a bye bye block, just as it happened here.
Usually using second hand parts, are the worst choice u can make.
Ive been there. Ill buy new to spare the time and stress.
To repair something "for fun", is actually not fun at all.
Just tons of work and stress for what ?
You fix something, something else gives in.
And u get bored of it anyway, after a while..
I had like 7 cars till now.
Ive always said: ill keep this one for loong time.. well, i havent.. :(
Current one works perfect, except it has idle issues. Nobody knows what it is. Could be an electric circuit problem. Imagine having to change all of it.
Pas.
So it's gonna go soon.
Even if i like it alot.
Thank you for not trash talking about machinist who did restore your engine block. And thanks to machinist for taking responsibility
I know you've has some practice but that disassembly was breathtakingly fast. Wow!!

Pulling an engine out by yourself has to be incredibly difficult!! Impressive

I don't know how to say this without sounding extremely sappy, but, don't beat yourself over this any longer. I understand the pure frustration and rage you must have felt, but this is beginning to take a toll on you. I mean, you sounded utterly broken at the beginning of the video! And it bears repeating: it was NOT. YOUR. FAULT. Take pride in that.
You rebuilt a goddamn engine without prior experience, and it went bad only because of an incredibly bad chain of events outside your control. Hell, maybe if you didn't change the thermostat it would've blown up even sooner.
Take a rest if you need it, get more than one stiff drink if you need it. Just don't go up barging into other people's garages! (wtf was that, seriously).
Hear hear!!
I knew it wasn't anything you did Sreten. Of course we want everything to be perfect the first time, but with all this new knowledge and practice, you are now capable of repairing anything. Failures teach more than successes-thanks for sticking with the process. This tired, old lump of a B7 will be out bombing the Autobahn in no time. Prost!
This was painful to watch, I feel bad for Sreten, but can't help but admire his positive attitude and hopeful spirit. Hang in there Buddy, you got this!
After such a mamoth job I would have cried if the engine had failed like that, but you remain unfazed and plough ahead. That is your strength I believe. well done .
Content creation-wise these things are a goldmine, but I can only imagine the disappointment after the test run.
But things like these (and the dry humor) make you and your channel by far the best automotive content on CZcams.
Greetings from Finland
Tremendous respect for your endurance !!
This is so much learning and an example for all of us. Keep pushing!💪🏻
I said this already in Part 7: At least from what you shown in the video, there was nothing to be seen that you would have done wrong in the assembly. I am saying this with >20 years of working in engine development. Of course we didn’t see every step but you are so meticoulous in your approach to this, that it would have surprised me if the failure could have been traced back to your part of the job. This is definitely sad and I feel your pain but again, it brings good content and you have A LOT of people around the world cheering for you now! (I also think going for the used engine is the right desicion - I would not have given the first guy a second chance…)
Well he could have measured, but I don't think many do before they find out something is wrong
@@henrik1743 while he didnt video the assembly, in his other vids he always measured everything he himself did. he sent it to a professional for the cylinders, so you should be able to rely on it.

Sreten, I just wanted to say that I really appreciate you and the content you produce, it truly is some of the best on the whole internet. The precision, and the way you manage to show every detail is second to none. Your explanations are so to-the-point yet thorough that I often feel as though I could do what you do.
Can I tell you're extremely put-out by this experience in this video? Absolutely.
Am I impressed that you documented the whole process of disassembly again for your waiting audience, and then spent the hours required to edit it, while it was all still fresh? Even more so!
It takes something to be able to get up in the morning and do this. You could have done it off camera, you could have just parked the car and given up on it for a while, you could have offloaded it as a knee-jerk response. But you didn't.
Thankyou! And the very best of luck taming this beast and getting it sorted out! :)
I admire your resilience and patience, good sir!
Sreten - I truly admire your perseverance and endurance. It was such an unfortunate setback and painful to watch, and I can only imagine how you felt.... On the flip side you can now assemble the Alpina engine in your sleep. You are an inspiration!
I do like his channel and determination: " he will build it again and he will push it hard on the autobahn if it blows up at least it will go in full use " best quote..
"if it blows up, at least it blows up spectacularly"
well, i really hope it wouldn't 🤣 looking forward to see this alpina b7 back to its glory again.
Very sad episode but hopefully the engine from Poland will be in good condition as described.
Drunk guy was so random, that Dominic guy owes you a crate of good German beer for having to deal with that.
I doubt. It may sound new to you but the BMW drivers are idiots and the fact that that engine is selling used tells a lot 😉
I love how Sretan said "I dont speak german" lmao
A great lesson in Metallurgy and precision 👍🏼👍🏼
I admire your persistence, dude!
Only non-standard part is the sleeved block. Cylinders 7 and 8, the hottest ones. Heat deformation due to unproven interaction of different materials and construction. It ran fine when cold and with heat and pressure the liners deformed. The 2 metals expand in a different manner. Most likely there simply is not enough room in the block to install liners with a stable enough wall thickness.
The fact that the liners have moved further proves this.
You cannot bore cylinders to such uneven measurements so the only explanation is deformation. Even if you did measure them during assembly, you would not have detected any anomalities. 0.02-0.03 gap is normal for BMW cast iron blocks.
You did everything right and by the book. The sleeving company is not up to the task. 10y experience hin oder her. Ending up costing you thousands. Buy a new block. It comes with new pistons. At least for BMW engines, should be the same for Alpina.
Imagine having to do it a 2nd time and it failing again. Not worth the risk. Forget about the used engine. Just more frustration and needless work as a result.
Do not reuse the oil cooler. Regardless of your efforts you will never get it clean and it WILL introduce trash into your clean motor. Been there, tried that, cost me a motor.
I kinda have to, it's brand spanking new, over 700 euro worth of parts. Besides, none of the crap got in there because oil first goes through the filter and then the cooler. I already let it completely drain and it's clean, no shavings or anything. Had it actually spun a bearing, we'd have a lot more junk in the oil, but here filter caught most of it. Of course, anything that's going to be reused will be thoroughly cleaned.
@@M539Restorations get one of these electric pumps to drain oil from lidl, make a circuit to flush diesel through it (yup they are safe to pump diesel), let it run for a few hours, should clean her fine. or at some ship ports or industrial estates you can find radiator core cleansing services for heavy machinery
I don't know how difficult it is to remove shavings from an oil cooler, isn't it just a pipe with radiator fins to disappate the heat? I'd be less concerned about blowing out a pipe. I don't think they design the cooler to be some obscure bunch of fissures and crevices. It looks like a radiator on the outside, complex, but inside? Probably a pipe. No?
I applaud your efforts....great patience. You are a class act!!!
On the surface this looks like a terrible incident, but look at how much you and we are learning as a result. I've never rebuilt an engine in my life, but as a result of your videos, I have learned so much. You're an incredible teacher and narrator. And look at how many views these videos are getting. What you've built with this channel, your dedication, and your ability to solve complex problems is remarkable and beyond human. Congrats on all your success.
sure morty
At 51, and having worked on so many engine's, you were meticulous in every area of the build. What I love about you, is how honest you are, and how happy you are wrenching to give life to these old car's, otherwise they would have ended up in a metal foundry boiling for sure. I feel bad that this happened, and that you had the accident with the other car. One good thing is that you weren't hurt, because that would have been the worst. I was thinking that at least the catastrophe didn't happen when you were driving fast, might have caused much more damage. I know you will drive this Alpina again, and it will be perfect, as long as the engine from Poland is good, but i would not trust that guy who did the work on the block another chance with that kind of block for sure. God bless from a girl in the US.
Thank you for the kind words!
Girls like these are keeper 👌🏼 kind and car friendly 😂
@Danny, yes i am 51, but i get carded when i buy wine lol. The bad part is that i have ms, and was injured at work, which required many surgeries that make me feel like i am 91. I still work on car's, but not very fast lol.
@M35 Restorations, just pointing out what i and everyone else see's. You remind me of my grandpa, he had the same sense of humor as you, and taught me as a kid to fix thing's because he didn't trust people after being scammed, and had gotten. to old to do everything. I taught myself how to fix car's, but it really comes down to either you have confidence to look at something, and can see how it comes apart and goes back together, or you don't. Sreten, you have one of the best you tube channel's, and put out great video's that show your talent, and ability to teach. Thank you for being you, and i look forward to seeing the Alpina finish the race.
Learnt a thing or two myself from watching this episode, very informative. That Alpina is a marvellous looking thing I must say, defiantly worth one more throw of the dice to rescue. Thanks for the amazing content, we car guys really really appreciate the hard work you put into this channel.
More power to you my friend. Great luck with the new (used) engine!
No matter what, you did a great job 👏 of reassembling that engine and I learned alot from it. Thanks
Hey Sreten, it’s really sad to see, that the car broke down… but it‘s impressive, that you don’t give up, and repair it again. Your videos are very interesting, and also satisfying to watch.
Keep it up man!

This was a first time when I see how someone disassembles a cleanest engine ever... Sad story, but educatable. Never trust anyone and double check everything even if you trust 3rd party, especially when things comes to engineering! Thumbs up, never give up! Big thanks to this priceless video (study) materials! Bless you and happy Easter!
Sreten, another great video. I love your enthusiasm, and your plan going forward. I love the fact your going too go again with this project and not give up. Brilliant 👍👍
Good luck with the new engine 😊👍
7:18 Poland strikes again! We as Polish car people laugh that no matter how rare car or part or accessory, there will always be one lonely offer with it on OLX or allegro :)
Good luck!
„Success is going from failure to failure without losing enthusiasm“ - some dude. Keeping going man, don’t lose hope, great content either way 👍🏽
It''s a Winston Churchill quote that I like too.
Yeah keep filling the moneypit
Scotty warned us.
Don't give up Streten! We're all cheering for you!
I would literally cry if i did all that work and this happened. God bless you man
"It is not your fault, but it is your problem ... " :-) Well, at least it is good to know, that you did not do anything wrong. Fingers crossed for the replacement engine!
Sreten I applaud your patience and persistence. You will get it back on the road in no time. The random drunk showing up in the middle of this episode made me laugh mid sip. I have beer coming out of my nose. Cheers from Toronto.
That's those Toronto Ontario guys for you, beer and snow. From a guy who knows, Stratford, Ont.
@@charliefox7206 bucket came tru, talking mad shit, alhie 🤣 had me wheeeeezin
@@charliefox7206 that's no where near Toronto, prolly more coke up in the boonies you live in styll, nize up.
@@MrDengo999 we drink more beer, because, we're in the snow belt.
Streten, respect! Welldone for not giving up!
I feel your pain! Don’t give up with it being not your fault. We learn from this and things can only get better . You tackle the impossible and make it possible. This is why I subscribed to watch your channel.
This is what this channel needed, a local town drunk! Bravo! I look forward to him joining the channel again in the future
If only would have been a funny one
this is such a sad episode :(
I hope the engine from poland will be good!
Keep up the amazing work Sreten, we are always there to support or help if we can!
Man, your content is pure gold
Top marks for your perseverance!
It seems you have acquired your first V8 living room table. ❤️
You can learn alot about someone when they're faced with a huge setback. I salute you for your attitude and ability to get back on the horse.
So sorry I feel your pain, but great attitude to have, good luck !!
I cannot imagine how frustrating this could be but I like your attitude: never give up. Looking forward to the next video.
" i am getting pretty good in this" that one made me laugh, i like how you always try to look everything from bright side.
Wish all the best man, i adore watching your videos, they inspire.
You said you did not sleep very well, pleas take care of your self, so we can enjoy more off your's videos in future.
Am sure you know this, but it is not bad to be reminded, to enjoy in your's journey to goal.
Need to add some to what you said - I've been around the world and still didn't find a nation which people have more self ironic sense of humor then Serbs do, accompanied with "out of spite" attitude. Sreten is a clear prove of just pure that!
While you were opening the engine back, we can see how well you assembled it for real! You do amazing work! Happy Easter!
Really admire your dedication and never say give up attitude. Failure is a stepping stone to success. You will definitely win the next round. We are all behind you on this. Can't wait for the next video. God bless 🙏🏿
Enourmously educative, thank you for this. Deep breath, and at it again...
My sincere condolences . . . I've spent 35 years of my life working in garages on cars and I feel your pain, it is probably one of the most frustrating agonizing state of mind to be in, extremely stressful and we know how stress affects the human body . . not good.
Keep up the good work, I'm enjoying your display of resilience and positive attitude in the face of adverse circumstances!
Honestly, if I had my life over again, I would NEVER go down the road as a automotive technician. There is never enough training and the technology in cars is accelerating faster than we can keep up with.
Same frustration is in every domain.
At least in car industry itll be electric soon (i hope) Fewer parts.
These ice, are a nightmare in my opinion. You fix something, something else gives in... I think their time is up.
Cars have developed in 35 years a lot and the technology has become more complicated and advanced, but trust me, it's nowhere near as much as in the IT field. I worked in IT for some 15 years, and now that I've started to work on vehicles, they feel a lot simpler :D
@@TNX255 i feel this, I.T changes frequently
@@dan_6915 total rubbish, IC engines are a thing of beauty, been doing racing engines for half my life now, andI still love them. Its always the human factor that messes things up, you just gotta double check everything. Electric cars are utter crap by comparison. I Always check subcontracted jobs before installing, too many inexperienced idiots on the loose these days
@@ValladolidArde
Your opinion doesnt matter in the grand scheme.
You make engines that last one day! lol
I dont care about that.
I'm talkin about everyday life, and engines that has to last 10 years of use, if you pay 40 grand for a new car.
Electric are better because has fewer parts. Also in term of performance, i dont think it's even necessary to talk about.
Ive rented one of those electric nissan. It takes off like a fckn rocket. My stomach didnt liked it at all.
Imagine one of those 1000 hp tesla.
And the noise.. i fckn hate engine noise, with all my soul!
Driving for 5 hours or 8..
I got fckn tinitus because of cursed engine noise!
It's time to scrap them all.
Definitely my favourite CZcams channel by far, not only does Sreten teaches us to fix old bmw (which are by far the best make of cars) but to have patience. Keep up the good work and keep the content classy 🙌🏻
Thanks for all your work on the cars and videos. These classics are such amazing works of engineering, they absolutely deserve the tlc you put into them. I've had a few myself, a couple older than what you typically tackle (e12, e28), and did a lot of work myself on them but not to the extent that you are able. But I can absolutely attest to the mechanical genius needed to work on these over-engineered beasts. Had a synchro go bad on the gearbox on my e28 and the only person I could find who had the bravery or stupidity to tackle it, in one of the largest metro areas in the USA, was a toothless lunatic who worked on lorry transmissions out of a semi tractor trailer mobile workshop. He had to cut the old bearings off with a torch to get to the synchro and bake the new bearings in an oven just to get them expanded enough to go on. Appreciate the tremendously insightful and entertaining work.
I just wanted to stop and admire your drive for work even after an engine you just rebuilt went bad, you jumped on it straight away and dove in again . That’s sheer motivation from you and it’s so admirable! I’m not a big fan of BMW’s and I don’t think I’ll ever be, but I am a huge fan of your work even though I’ve started watching your videos just recently, I am just watching them all one after another. Your videos are just so educational and full of quality content for us, and you as a CZcamsr are among the very best, just a handful of this type that delivers this amount of quality. Keep it up and good luck in all your work!
By the way I would recommend subi performance for a real sleeve job, they know their craft
Wollte ich auch schreiben 😂
I like your testing method at the end... lol. One thing I learn over the years assembly racing engines is always double check the machine shop, I was in your shoes couple of times in the end if you assembly engines is a good investment to buy a set of micrometers and dial bore gauge because in the end pay off. Great video.
I admire the dedication, the spirit and the will you've put into this B6. It'll be back to full glory in no time.
Greetings from Spain!
What a patient man you are!
Now I know why I have see so little Alpina B7 content from this generation on CZcams, only Hoovie and Sreten.
Huge fan, watching your work is therapeutic, keep it up!
P.S Would love to see a E24 M6/635 Csi on the channel its my favorite car!
Legit street cars is working on one also

Sreten, speak to the guys from Subi Performance. They are also here on CZcams and I'm pretty sure they are happy to help you out with the engine.
Keep up the great work!
Push this comment!
@@nymeuznymo9507 @M539 Restorations he is also an expert on sleeving blocks that are used for racing and rants about not doing it right frequently :D
Yes, from my dozens of hours studying their CZcams videos I can confidentially say, they should be able to do this job. ;) They are very precise in working and measuring and they have very good tools.
They really look like they know what they are doing. Sreten, check them! Look at this video when they are measuring a new block czcams.com/video/SdI5PEIOU-s/video.html
And with a 2 hours driving distance from Frankfurt, I would consider them as locals! 👍
Here's to you, Sreten, your commitment and perseverance. We live to fight another day!
Things go wrong in life , but we always learn through these experiences, as long as your healthy in mind and body don’t worry..great content , really enjoying the highs and lows , keep going…best regards gary .uk…
