- How to replace PCV valve / diaphragm without valve cover removal, what to watch for and what to use.
If your BMW produces whistle noise from engine bay or has rough idle and stall especially during cold starts, or has fault codes 28A0 or 101F01 among the others, that's what you need to check first. In case PCV valve fix wont work, whole valve cover needs to be replaced.
Apparently you shouldent but the glue / jb weld on the of the circle rim bit as it can glue the pcv valve shut, just put it around the outsides
Isolate the area like a surgeon,nice. Warming the plastic with hot air,great technique. Thanks
Thanks a million for this video.
I've had this occasional whistling noise issue for 2 months. Through the help of your video I successfully replaced mine on my 2014 335i. I tested with a flame 🔥 and it didn't suck it. My check engine light is gone and no more rough idling.
Glad to help
What code what your CEL on for??
Awesome Vid- doing the pCV test as well as swapping it out was perfect and exactly what I needed
So this took out the check engine light out for code p112f?
I can just imagine the mess I’d make of cutting that old pcv out of my n55. I’d end up buying a valve cover, for sure. Lol! Nice job by you, though.
You’re like a car surgeon. Nice work.
This was the issue with my 2011 X35. Following this fixed it right up.
Have the exact same model, half engine power message sometimes, engine power loss (can feel it when accelerating), lots of air noise, rough idle randomly like it’ll shut off but doesn’t. With the code 28A0. By chance did you have that code?
I would i have seen your video before i attempt to change my pcv cap on a n53 engine. I destroyed a bit of the gasket cover during removing the cap ! Your solution with the dremel seems good to me.
it requires bit of a patience and ideally cover VC with some rag or cardboard.
I got the same problem.i got a 2013 bmw x5 xdrive35i and my check engine light came on plus its idling and that stupid load Squealing noise plus i gotta give it gas as soon as i starts it up because if i dont it will trun off.
Hi! Many thanks for the video, i am getting mine replaced soon as it started to make noose only when i come to a stop after accelerating or downshifting. I did the fire test and it seems to be. Will make a video and i will provide feedback
Thanks for a good video. My 2011 Mini has the same PCV membrane but a cap that is held on with clips. They want you to buy a new valve cover but I will get my cap off and replace it with a new one.
Wow this seems to be a great fix to a bad situation to especially if you can't afford the valve cover at the time,would you consider this a temporary fix or is the Pcv valve replacement still holding up for you down the road awhile. Again thank you for looking out for the little guys
Thank you, after some time and more research, i would consider this as temporary solution. And replace whole cover when finance allows so.
I did the same process with fire and it was the same, so I reemplaced pcv today wait until tomorrow to star it on, hope 101F01 left the chat
did it help ?
Did mine and it turned out to be a great fix but only for a couple of hours and now it’s singing like a canary , it’s even worse now , mine was the vanos-bmw one and it sucks ass but going to try the bmwfix one and see what happens, as for this one, it looks like the original diaphragm
Hi I was wondering would it throw a code out for that my car is running lean stalls when I come to a stop
do yo have any codes ?
3M windshield glue works extremely well for gluing it back together
Why isn't anyone using high temperature silicone? That's good for 100s of degrees. Windshield and jb weld aren't designed for high temperature

subscribed!! Nice education video!!. I do have 1st gen N55 (e82 135is) but thank you so much!
Thank you, more to come
Have you checked to see if the new valve is keeping the crankcase at the correct pressure and not too much vacuum at idle?
Hi Great Video Sir. excellent important information on the BMW pcv valve system. 100--100 . i have a issue with my 2013 x5 35i n55 ,3.0 litre Turbo.it has 155 thousand kilometers when it popup a code, 28A0. The top pan gasket was leaking a little on the rear (common issue) so i replace New Top Pan/ valve cover with new gasket, and also installed new spark plugs at same time. the leak was fixed,but still it has popped up the code 28A0. I do hear a 'whistle" from the front seal these past 10 months for a few seconds while i start it up in the mornings only (cold) and also when it is about 2--6 degrees temperature outside,it will whistle.During the summer temperature, there is No whistle from the front seal. the question is that,if i replace this front engine seal,will this prevent the 28A0 code From reappearing?? it really is a nuisance as i have to continue to rest it. BTW I was told it may be the MAP or the MAS Sensor ( i do use a ANCEL BM700 Obd reader for my diagnosis) ty for your thoughts and input
Hi, no map or mas sensor will whistle or throw code 28A0. Check pcv as per this video and proceed accordingly
do you know if this causes any types of leaks or just the noise?
This resolved the code 101f01 ?
Thanks man great video 👌🏻👌🏻
You give me a great help! tks a lot!
Hi there! Thank you for this video as this is going to save people a lot of money not having to change the whole valve cover. Just wondering would this method work similar to the N52N engine with the plastic cover?
Hi, yes it will also work
@@MechAdventures Thanks!
What glue did you use
JB weld
hello there can you please explain a little bit more about this pressure test that you did ? am i looking for the light being sucked into the pcv or out and also how long has this fix been working for you thank you brother
It lasts few months to a years, its super cheap fix worth of try. In worst case replace whole valve cover.
@@MechAdventures so the lighter flame should be getting sucked by the pcv , this is how you know it’s broken ?thanks again
Hello, can the same symptoms be present on the N47 engine regarding this PCV valve, since I experience sometimes rough idle and whistling noise, after putting down the gas pedal? I've already changed the crankcase pipe which is going from PCV.
Thanks in advance. Daniel.
yes it definitely could
Great video!
Going to try something similar to E90 N51 engine
How'd it go? Hear it's pretty hard to align them on straight with the silicone since it has a spring that pushes against it.
@@mty3606 Unfortunately I cracked the housing a little so it didnt quite work. Gonna replace the VCG
@@MehrLovin you mean valve cover? can get better than manufactor for around a $100

Hi. Thanks for the video. I was told my pcv needs to be changed by the last service guys and quoted me something ridiculous. I have 325i e90. Can you please suggest what part for e90 pls. Thanks.
Hi, thanks for watching. 325i has different PCV located under intake manifold. If you dont feel doing it yourself, find independent mechanic or enthusiast near you, it will save you a lots of $$ in future. Parts estimate $250-300, Labour should not exceed $350
@@MechAdventures again. Thank you for your response.
I am not able to find the required parts for a 2009 325i e90 online. Seems like a mission. Do you have any affiliated links perhaps?
Also at the moment , I dont have rough idle or any bad symptoms. The car runs smooth. That said one thing I noticed is. When the car is started and idling. When openeing the oil cap there is pressure release with a hiss sound. So basically close the cap and open again, will result in another hiss. Would this be a good indication of a failing pcv? Or the service guy trying to rip me off. Hard to say.
@@DancePista which country, or type of the engine or vin nr. go to realoem.com
@@MechAdventures thanks brother.
Site is great and worked via serial number. Still not so easy to find this specific part. Will keep looking in the menu. Cheers.
Will this cause any issues with the ECU/DME? I have a Short to Circbuit B+ - checked my grounds and battery. My car is an 2011 BMW 335i, Stage 2 - stock flash. Car was running fine but after the Downpipe was installed I started having this issue exactly as show on the video to the point it would stall. The car eventually had the Starter fail, never got it to start again it is still parked...really stressing out about the car just dumped in a parking lot at work...any help is highly appreciated!
Yes it will, any interference to oem software will cause some issues, that you need to discuss with tunner. At this point i suggest replacing starter, valve cover and remove any aftermarket devices
good video. I have a permanent code 101f01 staying even after replacing the boost pressure sensor. I guess this is the fix for that?
Yes this should fix it
@@MechAdventures Ok so I have cut the "cross" up on the cover, removed that plastic material and removed the diaphragm inside. Do I need also to cut and remove the material on the sides, down to the joint seam? This would make the new cap fit on snuggly? I just don't want to cut too much material. Hard to tell in your video, I think it is what you are doing at 3:30 to 3:35?
Ok an edit to this message. I figured out what you did, removed the extra bit of plastic down to the joint. Now I put the cap on snuggly. Did NOT glue it in place. Took the car for a 40 mile drive and it seems to be running much better. The check engine light stayed off the whole time also. The only thing is when I stop sometimes I can hear that squealing noise you talk about. I think this is because I haven't glued/sealed the cap on permanently yet. Right??
Can the car lose power because a bad pcv valve ?! Or bad performance?!
Yes, significantly
Isn't it better to use something other than JB weld since it's possible it will fail again?
Probably the same to use the silicone
Is it possible to fit the new cap & weld it from outside??
yes it is, as shown in video
Good
Thanks
My car n55 first start rough after 3 mints come somth how have Aida
Check your PCV
Hey there! Thanx for the video!! Have you replaced the whole valve cover yet or you still running on the same repair? Is it still stable ?
Thanks, Still solid, no rough idle, no shaking no squeaky noise
@@MechAdventures about to do the job right now. Thank you bro! Really appreciate your time.
No problem @@mustafaahmad7701
@@mustafaahmad7701 how is it holding up for you brother?
Your a legand!
Hello I hope you can help me, I’ve got a 2011 bmw 535i and giving me these two codes p149d p2177
Most likely your evap hoses around engine are cracked and leaking air.
@@MechAdventures you’re awesome I’ll take a look in the next few days. Thank you 🙏🏼
So ,this valve has to blow air out when the car is at idle?i have a n40 and when on idle i can here the air coming out from the small hole on the cap @MechAdventures
No air out, no air in
@@MechAdventures thanks for the quick reply! I took out the membrane and check it! No cracks , no nothing. But at idle blows air out! I’ll have to replace it?
@@giannismatziaridis2064 whats the issue with engine ?
@@MechAdventures At idle Revs goes up until 1500 and sometimes stays there ,sometimes drop ,otherwise dont have stable rpms at idle and also a small vibration at the engine .I have new Maf ,new spark plugs and i have change also the spark coils
Hey! would this fix the error code: 0028A0 on a 2011 n55 e93??
high chance it will
How's the PCV valve holding up? Still strong?
Still holding strong, no issues
Do you have link where to buy this repairkit ?
type N55 pcv into any of your local marketplace search engine
Can E90 also whistle / gurgle without having rough idle due to pcv issue?
No, e90 its due oil filter
@@MechAdventures what about a gurgling sound coming from intake / engine area. No codes or rough idle just the sound. Could it be pcv?
it is pcv.. same problem I have
hi
i have n52 engine but i have a little cap on my pcv from factory as this cap
has a bmw part number , should i put agin this cap on the new pcv ?
i don’t know why there is a cap here as normally pcv need to be free to work fine but if it is a bmw part it must have a genuine reason to be here
thks
Does the cap has hole in it ?
don’t know but here is the part number of it 11617547229
Its only dust cover. Put it on
ok but no risk of stopping the air coming out of the pcv breather ?
Dont worry
So it supposed to push air out or no???
No
Where did you order the part from? I'm having a hard time finding one for my 2012 535i xdrive
Ebay
Whats the name of that product ?
Did it also misfire?
Sometimes it can
HELP!!!!!!! I am getting the Error codes 28A0, 2D5A, 2C58, 2BEA after changing the PCV. Do you recommend changing the Valve cover. I tried changing the Wall Cover seals as well. Before changing the PCV I just had error 2D5A and 2C58 with rough idle and engine reduced power message but engine was having power
Replace valve cover
@@MechAdventures Will change it and give you an update
@@MechAdventures tried changing the wall cover. Same error and rough idea remains... Anythig. To be done after changing wall cover?
@@bimmerhacks Take it to dealer, you can have cracked engine head or worn cam bearings. Mechanic needs to inspect it.
@@MechAdventures OMG
I’ve seen someone use a pry tool instead of cutting it. Is cutting it necessary?
i was able to use a pry tool on mine. i used a sharp chisel gently in between the seems and it separated as though it was meant to do it. was on a 2012 x3
Should I jb weld it or would rtv work as well?
Jb weld
@@MechAdventures What if it were to fail again shortly after replacing it and I have to remove it. Would the jb weld be removable?
@@giovannyluque6034 if it fails again, you will need new valve cover anyways.
@@MechAdventures you have a point. Thanks for taking the time to respond.
Hello Guys,
I got this BMW X5 2012 xdriv35i E70 last year and I am trying to keep it for long term.
I have been dealing with a code : 28A0 ( Air Mss System, plausibility: Calculated air masses in the air intake system not plausible) for long time.
This is was has been done to the car related or not to the issue:
Order:
RELATED:

I have been doing some smoke tests and this is what I found and Fixed.
Charge pipe leaking: FIXED
Maf sensor leaking: FIXED
Map Sensor leaking: FIXED
Superjet pump vacuum line leaking: FIXED
Air box filter gasket leaking: FIXED
Valve cover gasket leaking: FIXED
Map Sensor leaking: FIXED
besides that I can't find more vacuum leaks with my smoke teste, I don't see any smoke coming out anywhere.
What else can I do ?
Something also weird is that the EVAP Monitor never gets done.
Car runs perfect , no issues , no bad idle, not knocking (just some times you can feel a small misfire but the RPM does not go crazy.
The light and code triggers when the car is being drive at constantly low RPM (1000rpm-1500rpm) and around speed of 25-35mph.
If avoid those situation I won't get the light but I will get the code sometimes as pending.
I am tired of this code
----------------------------------------------------------------------------------
Some Live data:
Short trim fuel are usually at 0%
Long term fuel are usually at -2,3%
Short trim sensor 2 is usually at 99.2%
O2 b1s1 is usually at : 1.4 - 1.5
O2 b1s2 is usually at : 0.7
Intake manifold pressure after throttle valve: 13.93 psi
Intake pipe vacuum before throttle valve (charging pressure - setpoint value) : 14.65 psi
Intake pipe vacuum before throttle valve: 14.63 psi
Charge air temperature: 115.7 F
-------------------------------------------------------------------------------------------
Please let me know what else can I do to diagnostic and fix this code, It is the only code that the car has.
Thank you so much!
on same rare cases there is crack within engine head
can i do it on my S55?
yes
If it sucks the fire that means it’s bad ?
yes
it's the same if you try to open up oil cap..and feel sucking
It is still working fine?
So far so good
Are these same parts for 2011 335i N55 e90?
Yes they are
@@MechAdventures OK before I order try this, can you tell me if your repair still is holding up after 1 year? Also, I noticed the membrane is not the same as the original pcv/ccv..
Fucken' EXCELENTE demonstration and knowledge of the symptom explained!!! I will order mine in advanced just in case my piece of shit F10 535i starts giving me more bullshit again!
be honest...did this really worked for you and lasted you long enought that you didnt had to replace the entire valve cover?
As per rough idle it did work, but i eventually end up replacing whole valve cover due to another issue. Thanks for watching.
@@MechAdventures mine is whistling some times thinking to replace cover do you recommend any replicas($100) or should I go with Genuine($450)?
Is it supposed to suck air in???
Because mines is constantly sucking air in while the car is on idle
If its sucking air in, its broken
MechAdventures thank you sooooo much, now I might be able to get rid of that pesky lean code your response was well appreciated 👍👍👍 definitely subscribing 💯💯💯
Thanks I finally got the valve cover yesterday so I took off the old one and put the new one on everything snugged in perfectly and worked perfectly at first it gave me a p0010 code and shut off like twice but I already replaced the camshaft like 2 weeks ago so I knew that wasn’t the problem so I drove on it for like 30 minutes and the code went away and no more check engine 🤪 thanks 🙏🏽
My mechanic says BMW works only with original parts is that true
Not necesarily, but your mech. covers his back for warranty. Fair enough.
Thanks for getting back to me. So just changing the pcv valve how is it working up to now. Mechanical want to charge 1100 for do it. I might as well only change that part if it work well
@@kleverAgudoMUSICai what i did works for me and some others but whole cover may need to be replaced as well, try first what i did and then if it won't work replace whole valve cover. In worst case you'll waste $20 or so.
Appreciate your time
obviously BMW wants you to buy the whole valve cover with associated priceless labor cost... I guess they engineered the plastic cover to go bad around the same time the diaphragm bursts apart.
The days of the 5mn replacement of the $10 PCV with an internal spring are gone.... now we have the 3hours job to replace the 50¢ diaphragm... danke 😂
do not glue to top rim
How does pcv holds?
So far so good, Thanks for watching !
For everyone who bought their cars on finance etc. Do this.
For the rest of us buy a new f**kin cover.
still noisy even two times changed
You need to replace whole valve cover
@@MechAdventures look at my post even replaced whole cover but still noisy
"still noisy even two times changed" doesn't say pcv or valve cover.
Maybe your O2 sensors gone bad
@@nk2x is it also related to O2 sensor???
