The joys of owning an E36 enjoy all your vids theyve been a great help to me 👍

Nice to see our VANOS solenoids filters being used in this project (at 42min), Hello from Doritech Motorsport 👍🏻

[@vinceevans3219]

How can we order some

[@stephenturner5836]

Hi Pamo, excellent video by yourself and a lifesaver to be completely honest, based in NI so Mr Vanos was a trek away. i tackled my S50B30 yesterday following rough idle when warm. O-ring upgrade and rattle kit as well as an oil Change today. Did all solenoid filters and dry solder joint checks before, so like new now. Now no hesitation in low rpm and rough idle has disappeared. Cheers Again 👍

[@ManSeeksCivic]

That's great sir. Glad the video helped and glad she's running better. Long may they continue 👍

[@lilo40676]

happy to find this channel... now i need an s50 engine rebuild video

[@yojay1]

Hats off to you for making the vid. Excellent content and really useful! Thank you

[@nilshildor]

Thank you for an amazing tutorial!! I might get on with it myself now..

As I’ve said before mate. You are a legend in my eyes.

Thanks man 👍

[@icebear1935]

Good work very educational.

[@tommydaly18]

Great video, Thanks 👍

[@tommydaly18]

So today I finally got around to doing this. Thanks for taking the time to make a great tutorial. Unfortunately someone had already been in mine and I've found the plastic washer on the oil pressure valve with a crack all the way through one side . 😭

Hi! Is neccessary the specific timing tools for the s50b30 timing process? I’m looking for the tools and all of kits seems to fit both s54 and s50 and they are a bit suspicious …

[@user-eh6bs9km5b]

Good evening! Please tell me, where did you buy spare parts and tools?

[@Steve-ei6ew]

Hi Pamo, great vid and watch your others with interest, i am following your advice as i have exact same problem with my M3. A couple of questions please ...... I have tested my solenoids with a 9v battery, they are clicking but not as loud as yours it seems? does this mean they are OK? as im using just the standard 9v battery..........also what was the outcome of your vanos work here,did it cure the rough idle etc? thanks in advance

[@ManSeeksCivic]

Hi Steve, thanks for watching. If the solenoids are clicking then they are working - but the sound should be a positive tick, I wouldn't worry about the volume here as the video had the audio enhanced to demonstrate the sound. As for the rough idle - yes it did have an affect and fixed the murmur . It was the final chink in the armour along with shims, split rubber hoses, worn plugs and all the other usual 25 year old BMW parts I've changed.

[@Steve-ei6ew]

@@ManSeeksCivic thats good to hear m8, mines 28 this year......ive had it 3 years and the bugger is still running crap after numerous parts and inlet on and off, mine bogs down between 2-3k and idles shite,i did the TPS few weeks ago and its pulling better but still not idling......i took upper solenoid out and the large rubber ring was broken in 2? so im hoping to get away with the new seals kit for them both, circular filters seem ok?

[@ManSeeksCivic]

Ugh, you've had fun. It's all worth it in the end - the satisfaction of fixing issues like this never gets old - especially when you've invested so much effort. I'd change the filters whilst you're in there, for the cost of them it's not worth the doubt down the line. Good luck sir 👍

[@hannes5605]

Hello, i have a question that i can't find an answer to. Is it possible to change the timing chain without removing the cilinder head?

[@ManSeeksCivic]

Yes, but the cams have to come out.

[@barakabushi]

Hi Paul, is this engine runs by MS41.2?

[@lukekennedy6613]

Hey pamo could you tell me were you get the solenoid filter gauges please

[@ManSeeksCivic]

I'm sorry, I can't remember where I got them now. I'm trying to find the receipt to find out.

[@lukekennedy6613]

Cheers

[@larshaukdalen5758]

Hello! I am monting vanos again on my s50b30. But i dont know how to find out how the spline/gear that goes inn to the intake cam sits! Do you know a easy way to find out?

[@ManSeeksCivic]

It doesnt matter which orientation it goes in, just how much it goes in. Google the "besian systems s50b30 rattle repair document", it describes the process perfectly with great pictures.

[@larshaukdalen5758]

Hello again.. when i torque to spec the bolts for the sprocket(10nm) its getting to tight. Så the vanos wont work.. even whit the 24mm on the camshaft in turning the engien insted of just the cam

[@ManSeeksCivic]

Then I would expect the gear isn't engaged to factory spec.

[@MrP3can]

hello mate, got one question while pulling spline gear out of sprocket do i need to loosen all the allen bolts? my engine is broken over 10 years fells like vanos not working at all the only problem i can find is that both of my gears are impossible to move anywhere until allens are loose... 🙁

[@ManSeeksCivic]

Provided the vanos unit is removed from the head you should be able to rock the cams back and forth which will pop the vanos helical gear out of the sprocket. You shouldn't be loosening the cap head allen bolts in the sprocket at all. The cams can feel seized, this is normal but they should move with a reasonable amount of force. When you say your gears are impossible to move, can you elaborate a little?

[@MrP3can]

​@@ManSeeksCivic i do really think that vanos diaphragm spring and washer will be involved in this problem because nothing else cannot cause such a problem (probably nothing else), it seems like my hub pushes straight on sprocket and makes it really hard to move even with bolts finger tight, One more question, if assembled correctly sprocket should not be touching directly any surfaces on the hub and locking ring so a sprocket will not be pressed by hub and ring. In this case just small amount of force is required to move whole assembly back and forth, which is not my case. Since 2008 noone was able to find problem why vanos isnt working. S50B32 should not feel slugish with bad thottle response, solenoids Ok, vanos rebuild twice, brand new accumulator, vanos holds pressure in all conditions and no fault codes compression 12.5 bar all the cylinders no starting issues hot or cold and no stalling just rough cold running around 800rpm and hot idle absolutely smooth but really high at 1000-1100 rpm

[@ManSeeksCivic]

So you can't rock the cam at all with the vanos unit removed from the head?

[@MrP3can]

​@@ManSeeksCivic no, gear does not gonna move just by rocking camshaft you need 2 persons one just rocking camshaft and another pulling spline gear outward of hub , even though it is really hard to extract, takes about 5 minutes with luck cuz it moving just by a small amount, doubt that vanos can easily controll that spline gear

[@ManSeeksCivic]

I'd agree and sadly the only way your going to crack this is by removing the sprocket and inspecting all the parts. The helical gear shouldn't stick in like you're describing.

[@vinceevans3219]

Hi pamo What length are the new bolts m8 ?

[@ManSeeksCivic]

There are 2 types : 11121403470 = M6x42 11121403473 = M6x27 Called "Collar screw" - specific BMW parts but not exclusive to the M3.

[@vinceevans3219]

Thanks for that I use a company called Westfield fasteners They not cheapest but seem to do anything you want!

[@aaronguffey6159]

Have you had anymore progress on your 3.0 stroker?

It's done 3.5k miles and serves me well. Haven't had it back on a dyno yet, but am happy enough with the tune. Needs wheel bearings.... Joy 😂

Fell at the first hurdle no 36mm crank bolt It's got 4 male torx bolts ? Advice anyone please

[@ManSeeksCivic]

Undo the torx bolts. The balancer is held on by these.

[@vinceevans3219]

Thanks for that I did make a start on it I just put car in gear and pushed it forward and lined up the cams No guaze left in solonoid filters at all so trying to find some replacements

[@ManSeeksCivic]

Nice one, the lack of gauze is surprising. There used to be a UK company that produced them but this seems to be a non starter now. If you find some, please update us with some info 👍. Good luck.

[@vinceevans3219]

I might have some good 2nd hand ones coming from doritech One thing I wanted to ask where does the tubular small filter go I you had one in a bag on the bench that you placed solonoid cover on top of

[@ManSeeksCivic]

If I remember correctly it goes on the oil feed port. But it's been a while since I did this job.

[@vinceevans3219]

Pamo I can't get the piston out of the inlet cam it's stuck I've wiggled and pulled like fuck It just won't pop out

I've taken off the bridge pulled vanos unit forward and removed oil pump drive but can't get the unit to pop off the end of the inlet cam

What could it be stuck on its only a tiny o ring in there isn't it ?

Got if off Some nob head had put so much loctite on end of shaft it wouldn't pull through
