BMW Single VANOS: How It Works, How It Fails, How To Take It Apart, & How To Fix It!!

BMW Single VANOS...many BMW enthusiasts understand how this Bavarian variable valve timing unit added more power on top of the original 6-cylinder engine for the E36 platform. I want to provide a closer look into all the components within the unit, and explore the mechanical design that allows for the M50B25tu to independently control the intake camshaft timing (BMW later produced a double VANOs system as mentioned in the video). Furthermore, I want to troubleshoot the potential problems that occur on tired units, and show you guys the options available to fix one for yourself or find a reputable refurbishing service. Cheers!

Man I almost brushed this video off... good thing I didn't though. You're explanation of the vanos system, it's common failures, symptoms of each failure, and the breakdown of exactly how each symptom is caused was awesome! Not to mention your editing skills were top notch and your delivery was clear and concise. KZbinrs take note... or better yet just let channels like this make the content and stop over saturating the platform with shit videos.

[@Pawinning]

Thank you for the compliments! Yeah this one was a video that took a lot of planning and organization, and I used a lot of material from a report I made on the single vanos system in college 😂. I appreciate your support on my work 🙏!

[@vihangakeshan1017]

Honestly I've seen many e36 youtubers but I think your the best very detailed on instructions.

[@Pawinning]

Thank you :)! I appreciate your compliment! I strive to keep getting better!

[@vihangakeshan1017]

Ha ha cool man anyways if ever in need of parts from Europe just give a buzz. I do many exports on European cars.

[@jikjakz9144]

The detail and editing in this video is on point!!

[@Pawinning]

Thanks man!!

[@benjaminsmith4519]

I just want to say I worked in Aerospace with parts thats tolerants went down to the millionths when finished. As far as your concern about sandblasting as long as you use masking tape to protect sensitive areas that cant have blasting materials thrown at it. Which is literally what we use to at a shop I worked at that makes $50,000 rear rotor gears for the sikorski Blackhawk helicopter and I can promise you that yes it can handle it. Only thing is you will want to run it through a hot tank after words or other cleaning product pretty much anything to rinse off the dust. In Aerospace we used Acetone, Hot tank (for parts in early stages of machining), mineral spirits, methanol, and isopropyl for cleaning. Typically blasting was only used for pre copper plating for heat treatment and glass bead blasting especially after copper plating was removed. I personally don't think at all blasting should ever be used for cleaning. Blasting is like for surface issues like rust or resurfacing, pretty much using friction to get a smoother surface. Now as far as sandblast for heat treatment goes I have no clue all why they do other than to remove all grease and oils on the surface and to leave the surface dry and protected from rusting before heat treating and they take the shit serious too like when you sand blast for heat treating you have to use gloves to put the parts away when you are done and even wrap them in paper to avoid cross contamination from the surface they were packaged in. Thought I should add that any time you use a sand blaster keep in mind that you are removing STOCK as well from the part and in areas where the tolerance is tight that can have some really bad consequences if you blast some parts for too long or too many times

[@paulkim6175]

Excellent video. Maybe, should mention about left hand thread on bearing retaining bolt.

[@urgetodrive]

Great video. I really liked the dancing bolts timed with the music.

[@andrewyear81]

Nicely done young star. I've recently acquired an m52 to keep my m54 company. I look forward to seeing the differences in the 2.8 throttle cable initiated motor and its electrical throttled 3 litered brethren.

[@TWRX_Chuck]

Dang, killer video Pawin!

[@Pawinning]

Thank you for your support. I’m glad my content is helpful for your projects 😌

[@jakubbobkowski8615]

Definitely one of the best how to videos. What lube did you use on the bearings during assembly?

[@Yarenchak]

Very impressive! Thank you.

[@brandoncarmo580]

Dude, I'm new to the E36 world, you made the VANOS repair very straight forward! Great video!

[@Pawinning]

Thanks man! I'm glad my content has been helpful for you 😎

[@fixedandwelded]

Very nicely put together. I should definitely do mine on the trusty S50. Probably losing good amount of power there.

[@redjstc9123]

Got my first e36 328is and didn't know shit about vanos. Thanks so much for your time bro💯💪🏾

Awesome video man

[@Pawinning]

Thank you! I'm glad you liked it

[@mikgtc]

Just subscribed your Chanel! Really nice work my friend!!! The fact that you have 2 units to compare themselves and doing the actual work on one of them is the best you can make. I'm doing some research to repair my s50b30 vanos unit. That's from my M3 that I'm restoring. If you're interested, I can give you some feedback after. Good looks!

[@alexlt007]

Outstanding video. Excellent information and presentation. Thank you for posting this. I have a 97 528i with a M52. assume this is the same vanos unit.

Congratulation. Very good explanation.

[@Pawinning]

Thank you!

[@davidminie1088]

Nice job on your explanation with disassembly procedure! Just a quick question, are you experiencing a check engine light or are you hearing noise when deciding to rebuild unit? Or is this part of the tear down of the engine re-build? Nice job.

[@Paios]

ayoooo good vid. e38 boi over here speeding in comfort, catch me on them M parallels mobbin thru ur hometown

Thanks man!

[@jcfinch4389]

nice clean video super helpful, wish there were more youtubers like you out there, also do you by chance know if the U.S. spec e36 m3 so s52b32 has the same unit, from what ive read on the forums it does???

[@becomematrix]

Jc Finch yes, it does. The s52 is actually a bored out euro 2.8 m52. So same running gear for vanos.

[@khczitte]

Legend! Thank you

[@Pawinning]

Thanks for watching!

[@jajangsomantri1243]

thanks a lot guy

[@fofdeejay]

Great vid,tnx 👍

[@becomematrix]

👍🏼👍🏼👍🏼 no nonsense tech video

[@tinchodelacabeza]

Excelente! sobre todo por hacer referencias a las medidas de las piezas. Todos cambian piezas sin saber que medidas deben llevar. O si realmente hay diferencia entre la medida de la pieza nueva y la pieza vieja. Muy bueno!

[@mann318is]

Thanks mate

[@kirilchuk]

Gra8t job on full explanation . My only question, does the outer gear that's on the vanos needs to be aligned with the cam gear , because I can pull the vanos unit without a cam locking tool and I can reinstall the vanos with a slite movement of crank bolt back and 4th to where the vanos gear goes in to the cam gear smoothly .

[@davidg.9942]

one of few informative videos out there that actually explained all I need to know about vanos,,, have a question?- is there a recommended time interval you would absolutely advised on overhauling the vanos? I have 2004 with barely 50k miles-runs smooth no issues with power or torque, no rattle, no strange sounds,,, however age wise it is getting close to being 20 years old

[@elijahrecord7285]

We appreciate you soooo much

[@Pawinning]

Thank you! I appreciate your support 🙏

[@manuelalvarenga5365]

hello , hell of a video. love it will watch again and again. only question that did have. what did you torque to spec? The outside cover plate? or the torx screw inside the unit? and what were those torque specs i would greatly appreciate it.

[@BLACKHAWKTS]

Thank you Bro 😎

[@Pawinning]

You're welcome!

[@greasebin]

very nice

[@cccalarco3084]

Well done

[@Pawinning]

Thank you!

[@flyday2day]

sorry but this video keeps being so useful, i was just wondering wher can i check the torque and specs for the unit

[@alu7639]

I have a 98 323i and I've been having issues with no power under about 3k. I replaced my crankshaft and camshaft position sensors which fixed it for about 2 to 3 weeks and its right back to not working again. I'm gonna give this repair a shot.

[@threefive2072]

great video dude. helpful :) one small question: this unit is on US base model e36 3 series, and also US M3's ... correct?

[@David-xw6uh]

great video, but you have some video that show how remove the vanos from the engine.? What are the correct procedure!? if I have lock, the engine or something? thanks

[@E85LONEFOX]

Good to know, I plan on buying a used N73 V12 from an E66 (760li) that I would like to rebuild, I know that they are a very complex piece of machinery, but that’s what I like about them. I used to own an E38 (750il) with the 5.4 liter SOHC V12, no VANOS though. That N73 is probably the closest to the S70/2 that was only used for the McLaren F1, possibly the best V12 engine BMW ever built.

[@soundseeker63]

Great informative video. Is the double VANOS system basically two of these or are there differences?

[@Pawinning]

Yes they are similar. It applies similar timing control on the exhaust camshaft. Double vanos has its own tool set as well!

[@randyfleet9968]

Excellent video. Do you have a video that shows how to reinstall the vanos back onto the cam shaft?

[@Pawinning]

I do not, but I recommend checking out my friend Quinn's channel M3nace 🤘. He has a ton of useful diy videos and I believe he's made videos with vanos work too 😎

[@randyfleet9968]

@@Pawinning Thanks! Those videos had EVERYTHING I was looking for.
