In today's video I start taking apart my old BMW E36 engine (the m50 or more specifically the m50b25tu). This teardown may apply to e34 m50 and e36 m52 & s50 engine applications as well! Here, I cover how to remove the VANOS unit and take the entire cylinder head off the engine block prior to removing the notoriously fragile camshafts. Thank you to Eli from IgnitionTube for stopping by to help!
I have no plans yet on this m50 motor, but I'm either going to start a long-term forged internals build or a simple rebuild. But I'm open to ideas and suggestions!

It's refreshing to see the "younger" generation actually working so in-depth on an engine AND with such enthusiasm and professionalism. I truly hope you consider enrolling in BMW's STEP program...... oh by the way.....great videos.
Thank you so much for the kind words and for your support! I've considered that program in the past, but now that I've found a stable job in another field these DIY videos/automotive content remain a passion and hobby of mine :).
Don't even own a car but you're doing Gods work. This video documentation will help a ton of folks around the BMW community
+Peter Soboyejo thanks for the support!
YEEEES! This series is a dream come true. Ive been looking for a m50b25 teardown vid that is explained well for so long. Love the vids and how you explain the steps. One of my new favorite channels!
Kaelen Knopp thank you! I'm glad my video was clear! More videos to come :)
Thank you. You’ve motivated me to attempt my 1st time ever rebuild and successfully rebuild my 98 S52 with new piston rings & bearings, new crank bearings, head gasket, oil pan gasket, all new bolts. Honed the cylinders. Found a damaged steering coupling and replaced it too. All done with engine inside the car. It was easier than I expected. Hardest part was removing the subframe to get access under the engine.
I also learned that there is a process to follow for 1st time engine rebuild start ( Good thing I came across that video). I’ve learned a lot from this experience. Thank you 😊
I was taking mine off today for a head gasket. Had to rotate the cams to reach the head bolts then I forgot how they were oriented in TDC. This video saved my project. I was able to use it as a reference to set everything back up correctly
Currently building an M52B28. Hopefully should be done tomorrow! Video sure helped me with getting the head prepared to be removed tomorrow. Not my first time but I always refer here for refreshers 🤝🏼
Great video! I have an M50 with over 230K miles that needs a head gasket. After watching your video, I went from "I think I can" to "I know I can".
Dude one of the best videos I've ever seen. Great understandable explanation ( thank god somebody still knows how to speak english!) great visuals. Keep up the good work! Thank you.
This video is great, all business. I’m doing a head gasket replacement on my 98 single Vanos 328i. Thanks for all the tips. I’m rebuilding my Vanos, upgrading the cooling system, converting to electric fan, and replacing my heater control valve while I’m there.
I love this car and engine so much. It's such a pleasure to daily drive. Mechanical issues secretly make me happy that I get an excuse to start taking it a part.
I know this is old but this is exactly what I needed to figure out how to get my cylinder head off my 1997 2.8 Z3.
Thank you for this video. Great job at explaining what you are doing.
This is one of the best videos I’ve come across you deserve way more subscribers thanks for the good content🤘🏼
You have no idea how much you're helping me right now. I JUST started to teardown an s50b30 to put into my e30 and this video is saving me so much time!! Keep the videos coming. My plan is to replace some parts to be turbo ready.
+photojnt I'm happy to help! Further tear down vids coming soon!
y put an e36 motor into an e30
Bmw M3 e46 Good question. It's simple really. E30s are sexy af and the s50 has more pony power. :)
This video is so informative I wish I seen it 4 years ago when I was 16 and got my first m50 e36 coupe with a blown head gasket. Back then there was only 1 person that had a video of his speeding through a top end break down and I did the rest reading forums and what not. I didn’t use any special tools at all but I did take a shit load of pictures and notes. This video is the one good shit
I feel you! I made this video because I was on a similar boat. There were limited resources at the time (mostly forums for me too) when I built my turbo e36. I did similar things as well with endless hours of research, pics, and notes to make sure the first time around it went back together and ran 😂. after the build was complete I regretted not documenting things on video, and I just wanted to give back in a way, so I found that creating something that's useful using my old engine for the next guy was the next best thing. Thanks for the love, happy modding 🤘
Thumbs up...all the way from Jamaica. ..love bmws..bought my third one..e36 325i..going to do the timing chain eventually. .thanks for the vid
Love the vids man. This is a real help with rebuilding my m52! The detail is awesome. I will rebuild my Vanos now also. Cheers 🤙
As a 15 year old that plans to get an e36, this video is a lifesaver! When I get enough money to mod it, I’m definitely going to use your videos for help.
Hey man I'm stoked that my videos are inspiring you to pursue an E36 build! Good luck and thank you for your support 🙏
This and others of your videos were very helpful in guiding me on tearing down the top end of my 92 325is to replace the head gasket.
Not sure if you're willing to answer some questions, but now that it's back together, I'm trying to figure out why the temp gague rises to the red after only a few minutes from a cold start.
New thermostat, new water pump, ne temp sensor, new overflow tank.
Thank you so much for this video, was my entire guide to dissaseble the engine. This is also the first time im ever working on a car so this helped a lot
Seriously did a great job on this video. I really like the lack of bs. Excellent job. Cheers
+james griffin thanks man!! I appreciate the support and feedback

Great video Pawinn! That was hilarious calling for help! Lol!
Carlos Orozco thank you!
Just subbed to your channel. Love your infomation you have given. Im new to the bmw family. Ive just brought an awesome 98 328i four door. Currently living in New Zealand
+SMD824 Nz thank you :)!
Great video!!! Do you do one that shows how to time vanos when installing?
You’re the man, thank you!
good video ! i like these videos !
I'm asking everywhere i can before taking to much apart on my 92 325is and hope you might be able to answer a question.
To replace worn and brittle timing chain guide rails (the one operated by the plunger type tensioner on the side of the cylinder head), do you need to take off the tmobile chain front cover?
Im looking to pick up an e36 and it comes with vanos m50 that the guy said he pulled from the junkyard any tips and advice! Thanks for these videos!!
I have problems with vanos it's always give me misfire but if I unblock the cable of vanos care is working fine please advise.. what's the problem
I have a similar project right now. I have pulled out the engine and i am about to begin rebuilding it. I was wondering how would putting in 2.8 liter crankshaft and s52 2.8 liter camshafts affect the vanos system. Am i good if i just change the DME. My final destination is to put in a big ass turbo so i am reinforcing the whole thing
Do you think trying to put the head back in the car with the exhaust header installed is not worth the trouble? Or just struggle with the exhaust header bolts with them in place?
Very nicely done tutorial. Thanks!
Thank you! And no problem, happy to help as I can 😎
Teaching an old retired man new tricks. Thank you!
You're very welcome! I'm glad my video is helpful for you 🙏
With all your litle tricks to get it done easier you must have been a big fan of MacGyver 👍
What bolts did you use to mount the engine to the engine stand? (length, size, pitch)
Question, Is the m50 block the same for vanos and non-vanos?
At Step 8 - 6:15 - When you turn the crank CCW to create the ~16mm of clearance, I noticed your cam lock tool is still installed. Should it be installed at this step? I kept mine installed and when I removed the head I noticed that valves in cyl 2 & 3 were partially open. Unfortunately, I assumed that all the valves would be closed (forgot I turned the crank for clearance) and laid the head down on the table, valve side for like 15-20 minutes. Hopefully, I didn't damage anything. Anyway, I was under the impression that at TDC, all the valves would be closed. Does it make sense to disconnect the cam locking tool prior to turning the crank for clearnace?
love your videos keep it up
Also I believe the cylinder head bolts are stretch type bolts which should be changed. Is this the case for all M50s do you know?
What is the dimension on the headbolts? And is it torks? Reparing a blown headgasket on my M50B20, still haven't taken the top of yet
This is understandable thanks man
awesome video and channel loving it
Thank you for watching!
You're an amazing mechanic.
Thank you :)!
Is that the cast iron, nikasil or sleeved aluminium block. I am currently turbocharging my bmw and the thing is that here in finland you cant get your hands on sleeved aluminium cylinders easily. The m50 block is too heavy. Do you have any experience in sleeving aluminium blocks. Or would you recommend just running with the nikasil as its in good shape. AFAIK you can ofcource make power with nikasil but when shit goes sideways you are in much more trouble than you would be were you running with the sleeved or cast iron blocks
Man you are amazing, top marks.
Should I remove de vamos from my engine?
I want to add a turbo to a m50b25 vanos
Should I remove it ?
Hey I just recently replace my head gasket on a 95 525i auto because of over heating issues.. put everything back together..no overheating but the car isn’t running at full power. Thinking it might be the timing. I place it at BTDC timing blocks and flywheel pin on. Not sure what when wrong or where to start to fix it. Help anyone?
Great video
very very good video!
What a great video! It helped me understand the operation of Vanos altogether with overall timing. One question that bothers me is why the holes on the timing gear are slotted, allowing potential rotational movement if the 4 bolts get loose? Wouldn't that compromise the timing between the crank, exhaust cam and intake cam?
I can agree that slotted holes on the exhaust sprocket allow to remove/install the Vanos while maintaining proper timing but why we need slots on the timing gear?
Hey man! Great question and I too used to be pretty confused about the slots on both intake and exhaust cam gears and how it operates with the vanos system. My best explanation is in this video I made that discussed how to maintain the vanos unit itself. Hope this helps! ruclips.net/video/Y_BRIv_xqMg/видео.html
I'm doing should be reverse of the torque up pattern. It does matter but like a lot of things does not manifest a problem for so long that culpability is naturally vague.
Very nice, smart video. Very THANK YOU!
You’re welcome!
Good job!!support from ITALY!!
+sami nadif thank you 😌
Awesome bro subbed!
Thanks for the sub 🙏!!
Incredible. Thank you.
Thanks man! Happy to help 🙏
Watching this is making me consider getting an engine from a breakers just to take apart and learn on..
+stubbk3 go for it! The motor I picked up was like $300
Well done
Very useful video!!
+Bensajontte _00 thank you!
Man I wish I have the knowledge like you to rebuild my 95 325i convertible Vanos... I need it so bad and can’t afford a shop, my car is so sluggish off the line. 😞
Song at 12 minutes?? Good video. Thanks.
LOL at 12:05 thought he was a cardboard cutout :) Great video content but I don't think you should remove bolts from middle to end. The BMW Bentley manual states that cylinder head bolts should be removed from end to middle and is pretty much how most manufacturers state in their manuals. The way you shown is the torque sequence when installing the bolts. Correct me if it does not really matter as I'm sure you have done quite a few of these engine rebuilds to know more than the avergae Joe mechanic.
maan you remind me of ME ahhaaha...you're such a good lad
hello i got one question if i want to build a m50b25 block with s50 cylinder head cams and itbs i want m50b25 or m50b25tu with single vanos or it doesnt matter
Hmmm I would lean towards getting an m50b25tu, but you’d have to verify on the bimmer forums cuz I bet you someone has done it. A lot of cams are interchangeable between e36 motors as long as they’re the same head length. I was looking to put s50 cams into my car too!
So without using the special cam removal tool I was told to loosen each nut on the cam caps by alternating from top to bottom going from front to back until they were all loose and it was unsprung. So what you just showed by putting the cam in that position changes all of that and allows me to loosen them all except for the very end?
Yes, that method also works fine (it is a safer method in my opinion), my method is just an alternative if you want a quicker process than slowly loosening all the caps little by little. If you want a more detailed video about the process I recommend checking out the channel mybimmerspace. I learned a lot of what I understand with e36 engines from him
Great information on your videos. I’m changing head gasket on my M52B28. Any tips on how to remove a stripped etorx bolt? I believe it’s an E8. It’s the one near the front of the engine.
Thank you! Unfortunately I'm not skilled with stripped bolt extraction. I do know which bolt your referring to and that sucks it's stripped (tight location right?). Do you think you could hammer on a slightly smaller sized bit? Ive never tried this with a female etorx socket, but when removing the pressure plate on my clutch I stripped the hex screws and had to hammer a larger torx bit into each screw just to get enough bite to break them loose.
when unfastening head bolts it's recommended that you loosen the outer bolts first and work inward to avoid war-page while loosening
it's vice versa when installing but opposite (inner bolts to outer bolts switching from side to side)
Thank you for your feedback 👍
Question? I'm going to swap my vanos out for a Dr.vanos stage 1. Do I need to remove the thrust washer plates and the timing chain/sprockets as well?
No vanos should come off independent of the timing chain assembly, but you need the lollipop shaped sprocket tool to move the sprockets for vanos removal and installation
I have a e36 328i 5spd these m50s are like the m30s very strong
I agree 😎🤘
Great video, the only wrong you did is when removing the cam, you've probably bent it! You have to loosen the guides evenly, every bolt quarter evenly across all cylinders when you are not using the special tool 11 3 260
Thank you for your feedback! I agree that these cams are fragile, and yes you can loosen every guide slowly and evenly when doing this without the BMW cam removal tool, but I've used this alternative method twice before with no issues with re-installation nor did I experience any bent cams.
I learned this technique from this video here: ruclips.net/video/wRnqy-7dT28/видео.html (in the video he talks about the same technique at 7: 30)
In the video, the host states that there is only one position you can rotate the camshaft to that relieves pressure on all the lifters except for the ones for cylinder #1. This allows you to safely remove all the other guides and then work on the last guide nuts a quarter turn at a time (as long has you hold the camshaft still, if it rotates on you with the other guides removed the camshaft will definitely snap/bend).
Hi, it's amazing. I admire your courage to do this very professional work. Where did you get so special tools?
I have e34 with M50b20 and by 2000 engine speeds, somethings slightly whistles. By warm engine.
And I am scared, that is somethings wrong in the head. The whole car is in very good condition, 60000 Miles only,
but 1990..
Anyway thank you for the video!
+Jan Poláček hey! I wouldn't worry about the sound too much with the low miles ur car has. But in regards to tools you can get them from many places nowadays, but pelican parts should get u started!
Great video. Is it still advisable to rotate the crank off TDC for the 16mm clearance if you are removing the head to work on the CAMs?
I’m wondering the same, I rotated mine for clearance before removing my head, but I’ve had the cams out now, wondering what my best way is to re-time the engine back up to tdc. With cams back in
Another great video, glad I don't have to do this again..
+Zwingfilms thank you! And yeah it's a hefty amount of work 😂
Thank's freind 🙏
awesome!! will you make a video on how to service it?
+mossmon that's the plan. The rebuild will be long term
i've got an m50b25tu with some head gasket problems, this video helps me a lot ! if i only change the head gasket can i skip step 8.1?? in the part two do you gonna change the head gasket and make the reassembly of the engine? thanks!!
+11mrc11 yes, if ur only changing the headgasket all you need to do is lock the cams, remove the vanos unit/timing chains and take the head off! The process then is the reverse of the steps pretty much. As long as everything is marked and at TDC it's straightforward! I do not expect to make a reassembly video any time soon because I plan to have a long term motor build with this m50! But it will come eventually. Got some cool projects coming up in the mean time :). Good luck with your headgasket!
