I've commented this on other videos but these closeups are outstanding! Most other videos on RUclips are panned out, while yours show each and every connector/cable up close. Makes a world of difference for a first timer. Thanks so much again!
That’s exactly my goal is for these videos, to actually show how to do the job instead of disregarding the viewers perspective. Thanks for the support man👌🏻
Excellent video mate, thank you!!!
Tip, if anyone is dealing with a botched valve cover torx bolt as i did in the worst place of all bolts i placed a piece of clothing material over the bolt and tapped on e-torx bit and proceeded as normal came off no issue at all!
Just followed this for my 630i absolutely brilliant guide well done George!!
Glad it helped!
I have used it to change valvetronic motor gasket replacement. I really appreciate video quality, detailed guides and overall professionalism . Wonderful job. Thanks a lot
Great to hear!
Thanks especially for the extra details of freeing up the ignition loom and taking out the black plastic piece on the firewall to free up the valve cover for removal. I could not pull my valve cover out on my E61 and so did an internet search to see if anybody had come across this issue and found a solution. Your solution worked. Thanks again!
Glad to hear!
What a good video, George. I may do this preemptively on my Z4 E89 with the n52. It has 93k on the clock. I appreciate you including the Valvetronic seal, as this is prone to weeping oil.
Same car, same mileage, just about to replace the valvetronic seal.
Worth the wait mate
Great vid, made it look very straightforward.
Cheers Peter!
Yet again, helped me thru a job on my 2006 330i. Your videos are always so easy to follow. Thanks!
Glad to hear!
Bom dia meu amigo...to com uma BMW 330i 6cc 2006.tampa d valvula d alumínio....queria saber d vc onde fica localizada a menbrana diagragma....pois meu carro quando esquenta ta asuviando i alcilando a marcha lenta....deve ter furado o diafragma
Thanks for spending time in this vídeo. Has been very usefull for me.
You’re welcome!
Very Detailed and clear, good audio quality. I plan to change mine soon on my 2006 530xit sport wagon. Thank you.
Glad it helped
Best Video I've seen on the VCG replacement. Thank you. I will be doing this over the weekend. Your detailed video answered a lot of questions I had.
Glad to help Kyle.. appreciate you watching!
@@GeorgeAusters the Valvetronic motor explanation was perfect.
Great video sir, thanks a lot
Cracking vid pal
Cheers mate
Excellent George I can already see the value of the 130i going up recently got myself one of these baby's
Defintely!
Good job bro
Thank you 👍
Bravo George

Wicked video thank you sir
Welcome Tony 👍🏻
Nice man!
Thanks buddy!
@@GeorgeAusters hey did you have any problems after this? About to have my valve cover changed and the mechanic warned that after this job some people have got rough running related to valvetronic. That the valvetronic is aged and after removing and installing it back, there may be problems. Even check engine light coming on for some people
good job - do you have the torque settings for the valvetronic motors screw?
Hey great vid! Could you tell me how to reinstall the valvetronic motor? Do I need to do anything with the 4mm Allan key? I just don’t want to screw it up. Thanks for your time.
Dam impressive job, out of my league but maybe one day when I have a garage (man cave) I my attempt jobs like this thanks too your inspiration.
Get stuck in and give things a go man!
I just did this myself and I started off stripping bolts when I tried to fix my brakes lol. I've came a long way since but honestly the hardest part of this job for me was removing the valve cover from underneath all the wires. The valvtronic isn't as bad as it seems follow step by step you'll be fine. Some bolts in back where a pain you'll need a swivel but other than that it just takes time. Took me 6 hours but I also did OFHG and removed the intake to replace the Breather Hose.
Thanks.😊
dude, thank you
No problem!
So George, do you just do that with the allen key on the valvetronic motor to remove it? Or does it have to be fiddled with allen key wise to reinstall it/not damage it?
Just completed this and it's not as bad as It looks. Might as well change your Breather Hose while your at it.
When you removed your cover, the 2 tabs on the gasket around the spark plug tubes were facing toward the intake. When you reinstalled, the 2 tabs were facing opposite direction. Was this a mistake?
Can you ore someone pleasssseeee help me i have a 3.0i n52b30A with a busted cilinderhead .. is the n52b25 the same does IT fit in my n52b30a IT looks the same but is IT?? Thanks
Is this the same process on a E90 N51 engine mine is a 2006 bmw 325i sedan 3.0L I6
I have a 2004 bmw 545i 4.4. if the valvetronic motor was removed, put it back on, and if it was not adjusted properly can that cause a random misfire???
How many bolts you need in total for replacement? I got n53
Ccv breather is the only reason I'm here
do you have to disconnect the battery before this process
Re breather hose after struggling with it for a couple of hours the way to do it is get a hose clamp around the bit you press tighten and it comes off easily...
Snap-on LDTBH5 set
Thanks I couldn't find any info on where those 3 bolts with the thick washers went watched dozens of videos
You’re welcome!
George, any way you might remember or have a record of the e10 aluminum bolt holding the ignition coil harness on? Previous owner's mechanic left the ground strap unconnected after doing the VCG... reconnected it in the proper spot thanks to your video! I'd like to replace the bolt though since it's aluminum, but am having a hell of a time finding the part in realOEM/FCP euro.
Just replace it with a steel bolt👍🏻
How long did it take to do? Thanks
When you put the valvtronic motor back on must you use the Allen to relieve or put tension back in it? Or it just slides and bolts right in?
is it possible that the excess oil is leaking in valvegasket?
To remove the crankcase hose, press the tab on the opposite side of the one on the video with your either index of middle finger, and use a medium size flat point screw driver to push down on the side you see on the video, and push back with you left hand. Do not rush, if loosing patience, stop and comeback later. If you break this hose not only is going to cost you money but great amount of time.
Thank you for the video. Needed to know how to do this to get to The Eccentric shaft sensor. Only difference is my valve cover is plastic. And when I took the valve cover screws out some of the inserts came out with them. 🤷♂️
Was anything else different with the plastic cover?
@@johannesf.2524 No. Easy job
@@johannesf.2524 Just Mark exactly which screw and insert go to which hole. If you don't mark them just set them in a line in order so they go back and exact same hole.
Why there is no adjustment when put back VVT motor?? Adustment isn't needed at all? Thankyou.
Michael Owen is actually pretty good with cars
Is it possible to remove the crank case breather hose once you've lifted the valve cover? Just wondered if this would give better access to the securing clip?
Not really without snapping the hose
Nice video George. So you didn't have any problems doing this without removing the injector wiring harness? ISTA doesn't mention removing it but the older TIS software does say to remove it.. And every other video out there they do unclip it. I guess it makes cleaning up that area easier, mostly. Good to know you can get to the bolts and remove the cover without, though.
No need to touch the injectors at all.. If you do then you'll have to replace all the injectors seals
Very nice. how did you put the valvetronic motor back to normal from the service mode? is it difficult? does the N53 engine have a valvetronic motor? thanks
Very easy to do. You rotate the worm drive the opposite way when you install the valvetronic motor. N53 engine does not :)
@@GeorgeAusters hi George im giving this a go at the weekend some have said that the valvetronic can go bad is that true any specific way of taking off and putting back on or is it a simple bolt off n on and everything stays in line?
Would it cause rough idle if I didn’t put the motor in service mode? I already took it off and put back in. Do I need to put it in service mode and put it back in and then turn the Allen again?
Mine did the same thing,not sure why it's still missing.did you find out why yours was missing?
Why the hell don’t people like you show how to install the VVT. That’s the only critical part in this whole thing.
VVT?
@@GeorgeAusters he meant the Valvetronic motor that I assume controls the Variable Valve Timing (VVT)
You didn't mention anything about the valvetronic motor stop relearn process after installing it.
So glad somebody said it. One of the most critical parts & don’t nobody wanna show that part. 🤦🏻♂️🤦🏻♂️
I have a scan tool that does relearns for BMW
Do you have to rewind the valvetronic motor when reinstalling? To get it out of service mode?
Yes
Hi george. I think mine is going. Would a symptom be smoke coming from where the heat shield is. I have smoke from the engine bay and goes away pretty quickly
Yes
When you reinstall the valvetronic motor do you need to wind it back in
No, the motor resets itself when you turn the engine on. Just need to make sure the worm gears are together
Did you re learn the valvetronic motor step limits? And if so how did you do it, and if you did it is your car with a turnable key og just an inserting key?
Hello I just completed this job and was worried as well about coding and stuff. Looked on forums and people swore they did thousands with no coding. I myself followed the step by step installed in back in the same way carefully screwing it back in while tightening bolts and it fired right up been fine ever since.
When you use the key, all it does is find the home position, but if you didn't get the valvetronic motor back in exactly the same position as when it was removed it'll be offset. The risk is either the eccentric shaft smashes into the limit or it doesn't actually make it to the home position. You should use the tool to relearn the limits fully.
Nice job...👏👍! is nothing complicated?
Haha some things can be!
Nice! Is the procedure far off from the N43 engine? Also think my rocker cover gasket needs replacing
Very similar 👍🏻
Biggest difference is removing the fuel lines that go on to the injectors. I did this on my n53 and its not that hard. Good luck!
The pre owner damaged the screws and just took bigger ones and destroyed some drillings. Any recommendations what I can do?
Cry
Is there anything that you need to do when reconnecting the battery? Does it have to be recoded or anything like that? Thanks.
Don’t know if you did it yet but the only thing that might happen is you get an abs/traction control malfunction light. If that happens all you haven to do is turn the wheel all the way left, and then all the way right. It resets the steering sensor
@@crazy4gta1 I actually did get a steering angle code as well as a 4x4 transfer case code. Took a minute to figure it out but I ran my steering angle adaptation function in my scan tool and both codes are now gone!
So isn’t it necessary to calibrate the valvetronic motor with INPA? I thought that once it’s removed, it’s important to calibrate it because it afects the rpm/idling sync?
No need
Definitely needed
ISTA P to relearn/calibrate right? Shouldn't the valvetronic motor already be calibrated from before "proper" removal? Thanks for the content sir! Great step by step video!!
@SDG Electronics was going to say i just did mine now its in limp mode and needs a re learn
Hi george .is the valvetronic gadget the same item to fit a 08 ,525i ,e60 ,2.5ltr (n52b25), my car being a Japanese import ,the year and model number doesnt exist in parts list . Cheers.
cool vid. quick question RE valvetronic motor reinstall, do you have to repeat the removal process in reverse? (i.e all the clockwise / counterclockwise winding). Thanks.
Yes👍🏻
Not necessarily required if you do the correct procedure of re-learning the valvetronic position in ISTA D. Common symptom of not relearning the position properly is the slight oscillation or rough idle which you can hear in this video when it starts up.
The rough idle was from a vacuum leak not from the valvetronic motor👍🏻
@@GeorgeAusters The high frequency oscillation you hear just after starting is the PID loop on the valvetronic system, since the pre-learned position did not create the correct condition for idle. That's separate to a general rough idle from the vacuum leak which is a slower loop, since it needs the O2 sensors.
@@GeorgeAusters I saw your other video, but most likely when you replaced the motor after changing the gasket, you most likely got it closer to the originally learned position. The tiny vacuum leak would not usually cause such rough running, but you need to look at the fuel trims to make any kind of conclusion.
Anybody seen this bloke and Carl Froch in the same room
? 😮😂
😂
Hello. I replaced the gasket valve cover on my N52. Unfortunately I have still leaks (smoke on exhaust manifold, close rear engine). Can my valve cover be out of order ? Thank you.
Have you cleaned the oil up?
@@GeorgeAusters sure I did it yesterday then I drove 10 miles. But today, I had smoke again. So I wonder... it is magnesium valve cover. Not plastic one.
My garage told me to change cover as it can fail again. Was watching videos where they say to change the rubber grommets too as they wear out and the bolts. But can’t source grommets without the valve cover .
Hoping for quick reply but the spark plugs need to be removed?
No
hi, i noticed you did not put any sealant on the valve cover gasket, is there any reason why you did not?
Because it doesn’t require any👍🏻
Valvtronic relearn?
First time I have ever seen someone actually use a torque wrench on a valve cover.
You must use a torque wrench or you’ll end up with a leak or worse, snapping the bolts
@@GeorgeAusters fair point, im used to working on cheaper cars
George , do you need to disconnect the battery before this job?
I would yes
@@GeorgeAusters thank you George!! I am just now getting around to doing this job. I have the same exact motor but in a five series.. Following your every step , I’m thankful you commented because I’m to the point where I need to disconnect plugs in dme box I’m thankful you answered sir ! Appreciate the video
i followed your video step by step. the oil leak stopped but now i have a low idle and the car stop by it own when i m turning or at stop and have to restart it every time . i checked the coil its not a misfire. 😮
Have you watched this?

what will happen if I removed the valve tronic with out following your steps is it going to be a problem when I install it again please help me because I did this today 😔
Can damage the gear
@@GeorgeAusters any solution bro do I have to rotate it clock wise and install it or what to do please tell me
How you calibration the valvetronic motor
There is no need to when reinstalling
Many people says that n52b25 need calibration. But if you are sure that dont need calibration then i do this job by my self
@@GeorgeAusterswhen reinstalling the VVT do you have to wind it back in with the Allen key?
@@jams011072 Yes
My valvetronic motor keeps as it sounds like skipping and won't come out. I've tried tightening again and again then ccw and no luck
I figured it out. 😑 I'm dumb
Do I need to disconnect battery when doing this ?
No but it’s best to
👏👏
What about initiating retting the valvetronic?
That's what I was wondering... does it reset itself once you crank the engine?
Comment tester la pompe à eau
Hello I have done this before I found your video. I Did not put a VVT motor in service position, and when I untighte the bolts it went out with some preasure. Do you think I did fuck up something?
It can end up breaking some of the teeth on the motor
@@GeorgeAusters you mean inside the vvt?
Did you put it back yet? Anything damaged?
@@DebtFreeCars all good nothing damagde
I hate to tell you this but the inner gasket was on upside down - if you look at the shape of the holes before you remove the old one at 17:49, compared to how the new one went in at 19:09 , the wider part of the egg shaped holes was previously upwards.. presumably to accommodate the guide tubes, but if those went in ok I guess there was no major problem. It could however be distorting around those holes, potentially increasing the likelihood of leaks around the sparks plugs?
I think it may have been installed wrong in the past.. Nevertheless I have done this job again since this video to replace the eccentric shaft sensor
@@GeorgeAusters I think you are right, yes! The shape of those holes is wider at the lower edge.. Good job. I found a couple of other vids and your old one was wrong but the replacement was correct.. My bad
What did you use to clean the inside cover with?
amzn.to/3bXHR1H
Thanks. I'll be doing this for my car this weekend.. just making sure I have everything needed
@@GeorgeAusters the link is not working in my country. Can you just give me the name? Thanks
@@coloradoqueen3282 seems like most people use “Brake cleaner” to clean the inside of the valve cover.
This shape seal/gasket does NOT fit an N52'N' engine, they are different!
Diesel are much simple easy to work with and reliable of course YES
How the hell did you clean it
70 or 7nm torque first u said 70 then u say 7v which is it bro thanks in advance

How much does a valve cover gasket cost?
The magnesium valve cover on fcp euro was 550 i believe. If you have the n52 with the plastic valve cover it's considerably cheaper, i think 250-300.
@@pilophemperor5723 lol where are you buying your car parts. I think i pay $55 after tax
@@_ki11shot_41 the real question is, where are YOU buying your parts? sir
Yeaaah no, not doing this one on my own that's for sure xD
I'm an aircraft mechanic so this is not too bad but I wish I had my own garage to do things like this...
FYI for people watching and considering doing this, YOU DO NOT NEED TO REMOVE THE FUEL INJECTORS!!! Don’t! It’s pointless and a headache
Yep, exactly why I didn’t do it👍🏻
Shit, when tipped it over all that sand and grit got put on the engine.
Thanks for watching man
@@GeorgeAusters that dump of sand just took 10 years off the life of that 😆
Appreciate it buddy
Have just done this job and it went well until I went to start the car.
It cranked but didn’t fire.
Checked the earth at the coils..all good.
Power at coils all good.
Checked the date stamp on the coils…it was…
06-05-19…I read this and though oh they are three years old all good it won’t be them.
What that date code means is 19th may 2006.
Turns out they were originals as the car is an 07.
The coils didn’t like being disturbed…and the car is on 130,000miles.
After a lot of messing about got a single new coil…spark plug in it. Jump lead gripped round the end of the plug to earth and turned it over. Had a spark.
New coil packs from gsf…and new plugs fired up straight away.
Other than that all good.
If I new the coils date stamp actually meant 2006 I’d of gone straight for them!
Are you sure you seated them all the way with the plugs fully on? I'd be very surprised at all the coils failing at once
@@GeorgeAusters
1,000,000 percent.
I tested each coil on the front cylinders lead…
On a piece of rag with the bottom of the spark plug grounded to a jump lead.
Then the new coil pack I got out…done the same and had an instant spark.
So put six new coil packs in and they fired!
Can post you them if you don’t believe me 😂
@@GeorgeAusters I even have photographic evidence 😂 I’m an aircraft engineer by trade so I’m pretty handy with fault diagnoses.
The date thing would be video gold for a RUclips video if I was into that jazz!
Only thing I would add to your video is that I have purchased a bag of m6 x16mm Allen key bolts of eBay. I replaced the bolts on the valve tronic motor and a few others as those male star key ones from bmw are crab!!!
