BMW N55 Squealing Noise Fix DIY

- In this video I show you what it took to get rid of a squealing sound which is common on N55 BMW engines.
We attempt replacing the PCV valve with an aftermarket solution and eventually replace the entire valve cover. The PCV fix might work for some people but if you already need to do your valve cover gasket and you're encountering the noise I'd recommend a new valve cover. You can purchase an aftermarket valve cover for under $120, here is a link to the one I purchased:

Here is the PCV valve I tried:

I could kiss you right now. I have been trying to find the source of this nosie for MONTHS with no luck. Changed out SO MUCH STUFF costing thousands but this, this is perfect. I literally jumped from my desk when I heard the EXACT sound. Thank you thank you thank you!
😂😂😂😂Same here dude! I've never been so happy lol
Same thing happened to me. I just paid $555 to replace my serpentine belt, only to have the issue occur again moments ago. Wish I saw your video sooner.
I had this exact same issue last year, thankfully I was under warranty took it to the dealer and it took 3 attempts to fix this issue. They replaced front and rear main seals then they decided on just replacing the entire valve cover. Finally I know what the real issue was, thanks a lot.
Absolutely amazing video, you solved my issue I took it dealership they wanted 1470 for replacing the valve cover gasket for my E90
I bought the whole assembly brand new. The dealership said I needed it. Definitely learned something new today from this video.
2009 328i N52 engine and I've the same exact noise! Not sure I'll be able to do it on the spot and I believe I'll end up removing the whole cover(full day job). But thanks for posting this, it made my life so much easier.
My wife watched your video and told me she knew how to fix the problem. i looked at her a little crazy but sure enough this was the problem thank you so much man.
Saving the day again! Great content and reasoning on your repairs. I have an E90 N54 (very similar to yours) and an F30 N55 (2014 also) and need to do a valve cover for a diagnosed low pressure (vacuum?) fault along with a few other easier items at the same time. So, looking like a weekend of me cursing at the F30 for a valve cover replacement (gonna use FCPEuro's OEM part though for piece of mind). Hope I don't mess it up too bad! ;)
Very good explanation. By the way BMW (Mauritius) couldn't diagnose this noise problem even after 3 visits to its Repairs Department. What a shame for the sole BMW representative in the country. Again Thanks; you're much better than those dudes. S.Thomas.
You know what your doing for sure! New valve cover vs pcv better going with the valve cover with built in pcv and same future issues. Good job
Great video! Thank you! I hope you keep this N55 car for bit longer and create more amazing content!
I have this issue right now with my BMW m235i with a 2016 M2 engine conversion (still a N55 engine). I have the start stop coded to be off all the time so I never noticed it till I accidentally switched it on and it made that noise and I freaked out. Because of you I Now I know what it is. Thank you!
Dude I have this issue with my 2013 335I; I took it to the local BMW dealership and they tell me they cannot replicate the issue. such a frustration - and what a bunch of moron that works the dealership, charges an arm and a leg and still can't find the issue. I thank you so much for this honest informative video. May God bless you for your help.
I got a 2014 335i and I'm going thru the same issue. Have you replace the pvc cap or the entire valve cover? What was the result?
That’s the same exact noise my N20 is making. I kept thinking it’s the belt or pulley. But thank goodness I kept searching for solution. 👍🏻
Fantastic video again! Thank you for your work.
Subscribed. I have a E70 N55. A friend of mine had one also without engine start/stop. After replaced the valve only it didn't the noise still happening so he had to replace the full valve cover.
Thank you so much I had this problem on a 2011 335i great job.
I have the same exact sounding issue on my 2013 X5 3.5i. When I undo the oil cap with the engine running the sound goes away (and releases vacuum pressure at the same time). I recently went to 2 different independent shops, one of which I highly respect and have gone to for years and they had no clue. Now I know what needs to happen. Thanks for the great video!
Have you fixed the issue? Was this the fix?
wow big thanks for this, I also assumed I had to dremel the old one off from the side...this looks so much cleaner! Well done!
Awesome video with excellent lighting. I hate whe people film at night with no adequate lighting. Great job!
Wow this video was perfect. Thank you.
Thank you so much brother I have same issue with my BMW 328I
Thinking a lot about that issue I bought a electric shift sensor For that issue 🙏🙏🙏🙏🙏
Good looking out my guy. That noise is driving me crazy
Very happy I found this, will be applying this to my e90 this weekend. Thanks a lot!
How it works bro
@@5htv230 worked out fine, was a pain in the ass doing it on car but not too bad. Had to take out the cowl and move the ignition coil harness. Just be careful not to snap the tabs on the valve cover that slid over the ccv (I snapped 2 of them lol) as it's very easy to do.
Thank you so much - this is exactly the problem I'm having with my 2014 335I. Local Dealership is asking $1,700 to replace the valve cover gasket. What a rip off. Thanks for posting such a thorough, informative video of the issue and possible resolution. You are super awesome.
i changed for 150
I have the same issue should I replace just the valve cover or the whole thing with gasket?2012 f30 335i with 80k miles..
Quick note here - It is a good fix however, do not seal the new cap in the groove with sealant. The cap is designed to suck air up around the diaphragm on the inside of the cap. If you place sealer in the small space of the cap - as shown - this blocks the air from being pulled into the diaphragm cavity. Place the sealant on the out side of the lip of the extrusion on the valve cover and then snug the new cap over that. Seal with some aluminum tape until the sealant dries or just leave it on. This way there is an air tight seal on the new cap but not on the interior of the new cap - this allows for the diaphragm to breath...NO squealing.
hi Philip, i saw another article online that require glue the membrane to the valve cover, bimmerprofs.com/crankcase-ventilation-part2/ which is the right way to do it?
I am plan to replace my PCV membrane on my 520i N43 E61, the PCV valve is part of valve cover, I could not find any video on google how to do it, yet.
@@qitianzhang3641 I would not glue it tight...it still needs to breath. Hope this helps.
Is there any oil ring outside?why still need glue?
Yes, my 328i convertible 2013 has this happen the other day and the dealership wants just over $2,000 to repair it, about $639 for the part alone, and I found a shop that will do it with OEM for $1,083. Not sure if this fix is available for my motor. If it ever happens again I will look into it deeper. But thanks for sharing this anyway. Only BMW could turn a 20-30 dollar part into a $2,000 repair! Like the hall sensor that went out in August, a $25 part, but integrated into the hydraulic ram that raises and lowers the top, so the whole thing had to be replaced at more than $2,000 and towing of $485. My third BMW 328i and the first one with any repairs needed. Any more like this one and I will have to live in the damned thing.
I’m getting this sound now at all times. While driving. Will hopefully get it repaired soon!
me too : ( Will you reply and let me know if this is the same issue as the video. I really want to fix mine or have it fixed and a lot of garage's don't know what it is. They all just stare at it when it makes noise and i'ts embarrassing!!!! LOL
True to your word. Thanks for being the Guinea pig for us. I don't have this issue yet, but i have a 2013 X5 N55 motor.
Thank you so much for sharing.. this is exactly whats going on with my 2013 X6.. exactly what it is..
It is great video. I do have the same problem . And I'm 70% fixed the issue by deleting the crank ventilation valve so I only get this noise in hot start not even everytime but cold start no noise at all
What do you mean by deleting crank ventilation valve?
Good deal on the Valve Cover! I bought my aftermarket URO Valve Cover from Autohausaz and spent almost $300...😐 Still ended up saving a ton of money doing the work myself though.
Did replacing valve cover resolve the issue?
Thanks gang. Needed this for my f06
Fr thanks so much for this video!
Thanks a lot I just replace mine using your steps
Just beautiful. After a very long search the vid I was hoping to find. Excellent well engineered repair and commentary. thumbs up and Subscribed
Another great video. Tnx!!
It's more than just replacing the CCV with that top part only. The whole valve cover has vents and air tunnels that get clogged and if not replacing the whole Valve Cover problems will still continue like loud whistling and humming after just replacing the Valve cover gasket only as the whole valve cover with build in CCV should be replaced... Ebay $90 to $140 for complete Valve Cover unit which includes the valve gasket already on it...
I agree with this as well if your new cap does not doe the trick. This will do it.
That is for after market and all people familiar with this repair say those are NOTHING but trouble, avoid them like they carry rabies. It costs more but get the OEM. Order it from BMW of Medford or Portland Oregon so no sales tax collected. That screaming banshee noise happened with mine the other day and the one repair guy that said he can fix it using after market valve cover also insisted my car has a 4 cylinder turbo. It has a 3 liter inline 6. He even claimed that is what the computer showed when he input my VIN.
@@markwalker3499 Did you use an after market valve cover and it gave you issues?
Why do you say to avoid them?
Awesome video. What is the Start / Stop feature? I have a 2009 X5 3.0 and have the same issue. Dealer wants almost $2,000. But watching your video is helping a lot. I am thinking to do what you did first and if that does not get rid of the noice My mechanic will replace the cover. Any additional advice please. Thank You, your video is helping lots of ppl.
Thankkkk you I had the same problem with my 435 .
Thank you this very helpful
❤️❤️ thank you for the help ❤️
If you car is making that awful noise and you do not change it will ruin your turbo as the function of the device is to such air and block oil and send it back to the engine. When it is ruined it sucks everything into the Turbo, brilliant video btw.
Dude, You're the Man!!
I legit laughed because this is exactly my issue but I'm replacing the valve cover anyway. Great video.
Christian Alvarez Did replacing your valve cover end up making the noise go away? 😕
@@MsForeverAndAlways27 yes it did
Thank you for actually replying, the noise is driving me crazy. BMW said it would cost almost $2,000 to replace the Valve Cover and I just wanted to make sure it would actually fix the high-pitched siren noise before spending any kind of money like that! 😅 I've been trying to look around online and see what other BMW owners are saying and some said it didn't help at all, so I'm so nervous in deciding if I should or not because money's really tight right now.
@@MsForeverAndAlways27 depending on how many miles your car has if it is close to 80 k miles you should do it any way because the gasket is going to get bad anyways, but do not pay $2000 find an indi mechanic,,, do not pay $2000!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
When you had the noise, did it happen frequently? I've had this noise only a handful of times. Several times when I had Jb4 installed and the Jb4 had a bad ground. Would get this noise and codes for my tmap sensor.
Then today I got the noise.again pulling into my garage and I did have start/stop enabled. I usually don't have it enabled, I was just testing it. Got a couple codes for airflow issues.101f01 104b01
Can you give us an update? how is it working out AM valve cover for you?
Thank u do much just did a valve cover and its making this exact noise iwas scared it was like a belt or something
When you see the price for this, you'll wish it was the belt. 😂
Also wanted to add onto my previous comment this is what they said "Found diaphragm for crankca()e vent on valve cover ruptured. Replacing valve cover. " And the issue that mainly came from mainly having my AC on.
This has also just happened on my 2013 N20/N26 4 cylinder, same thing!!
Good video. I was reading the flash point of motor oil is only 232 deg F. I wonder how safe it is to do the heat gun on the cap while still installed? anyone any thoughts?
Hey Nice Job, has the after market vale cover given you any issue up untill now or all is still good?
Can you do this with the valve cover still on or is it best to take it off
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
I did mine PCV replacement immediately after I drove the car so everything was warm and it was very easy to make a small cut on the side and pull out whole PCV assembly without even tearing it in to pieces. Unfortunately, howling NOISE from the front main seal did NOT go-away. When I started my X5/N55 on idle for about 5 minutes, the noise returned back, while car was ruining and noise was present, I carefully loosen the oil cap and I felt very high vacuum built-up, which was relived by opening Oil Cap and the howling noise was disappeared. After putting back Oil Cap, noise started again. So it is clear that there are many pressure regulating valves/ air ducts in the Oil Cover and some of them may be damaged as well. Before removing faulty PCV, I connected a 1/8 clear rubber tube (30 cm ) and other end slighly dipped in to water cup and I see it sucked water immediately because orange diaphragm of the PCV was broken at many places and also became brittle , after replacing PCV, the water sucking was not observed that means new PCV is not leaking to atmosphere. Noise issue confirmed that there is other pressure regulating hidden valves are faulty and which can not be replaced so my next step is to replace the Valve Cover.
Thanks for this tip! - My squeal just started today. I put a tube on the PVC cap hole and yes, can move air thru it. Also, the squeal goes away as soon as I pull the oil filler cap off (lots of vacuum and hard to get off) This tells me that the PVC valve itself is not working and there is too much vacuum in the crank case. I'll try the PVC hack first and if that doesn't fix it, I'll buy a new cover. It sucks though as I just replaced the cover due to an oil leak about 5K miles ago!
Finally I got full valve cover with gasket from autohauz az URO brand for 136$, it took me 10 hours and finally all noise gone! Relatives spark plug same time as well. Only issue was the rear side bolt to remove and put it back without using torques due to tight location.
@@kishorham Glad that fix worked for you! That bolt was hard get too, but I just put a swivel on it and was able to use the torque wrench. After all that work, I didn't want anything to cause the whole job to fail!
now i see not just i work for bmw factory:S good video thank you i will buy new one i see
Thank you!! 👍🏻
Is it very difficult to change the valve cover
Hey
What about oil catch can? If I install this will this solve the problem?
Can you do a oil pan gasket replacement on this x5 35i?? Please... i have a 2014 x5 35i 86xxx miles and is leaking from the oil pan drain plug😔 i don’t know if I should buy a whole Oil Pan for it, and I really Don’t wanna take her to the Dealership. Any suggestions?
I literally did replace the same PCV valve yesterday, 1/19/2020. I had the exact same ending: I need to replace th whole valve cover. Front engine seal started to whistle after I replaced the PCV valve I bought from Amazon.
I ordered a Febi Bilstein valve cover for 254$ and I'll replace it this weekend. Hopefully that will cure my seal's whistling, 3rd cylinder missfires and CEL.
2011 BMW X5 E70 35i with 84.000 miles on it.
update ?
Replacing the whole valve cover solved the issue completely.
I mean if we don’t care to use the auto stop feature, should we still replace it? Have this exact problem but I never really cared or liked the auto stop so I’m fine with just having it off to be honest. Or do I still need to change it?
Link for the valve cover doesn’t show the valve cover anymore, anyway u could show us another brand u recommend or an affordable valve cover? Please
Will this whole kit fit my bmw 335xi f30 n55 2013?
Currently have the same noise on the N52 motor.
yes im same the problem and i change up ccv & crankshaft oil seal the same come out !
Yo so I did this diy like 1 year ago seemed fine did the valve cover gasket yesterday after putting the car back together getting hella codes but they go away after clearing couple time but also the car is making the squealing sound on cold starts when opening the oil cap the sound goes away start after the car warms up it goes away too everything is put back together right this is my second time doing the valve cover gasket on a n55 do u think the pcv diaphragm went bad again maybe a crack in the valve cover I’m about to just order the valve cover cause idk what to do at this point ☠️
If we turn off start/stop function and drives the car like that, would it be a problem? Do I have to have valve cover changed sooner or later? My car makes the noise as well and I usually don't let start/stop interfere if I drive in slow moving traffic by using the manual transmission but yeah, the noise is annoying.
I have this same sound happening on my 2014 x5 f15. Is it safe to drive until I can get it fixed?
This is exactly what's happening with mine. Whenever the car is about to auto-off it starts whining. If I'm quick enough to hit the off button it will stop before shutting off. It sometimes does it while driving down the road. I figured since I have a pretty bad valve cover leak this is going to solve 2 major issues. These cars will keep you busy!
Next is the rack n' pinon :-|
Then the flaking display film
And rear door handles that are gunked up.
The windshield cowl is starting to crack
The sunroof fabric and now the headliner is starting to hang
This is temperary fix since the vents inside the CCV and valve cover also get clogged and messed up. Replace the whole valve cover brand new OEM on ebay for $90 - $130 high quality OE specs! I replaced mine and no more oil leaks, car starts and idles smooth cause no more vacuum pressure leaks from valve cover. Yes its worth every penny!
@China Boss i’d assume it’s still going strong. i need to replace my valve cover since my 5 series is squealing like crazy.
@@etn did the replacement fix it
@@StillBrokeOff i replaced the entire valve cover about 10 months ago and it fixed it. the pcv went out and there was a really loud sequel and rought idle. are you experiencing this as well? i would recommend doing the whole valve cover as just the pcv replacement may not fix it. if you're taking the whole thing off, might as well replace it !
Would having a tune be a factor in this??
What is the purpose of the PC valve cover..what this pcv do anyway.
HI.Wish I knew..The stealer didn't say any thing about the vc...They took care of two recalls but did not mention the vcg was covered as well.Wish I know..Oh well.My buggy is up and running w/ a bit of a miss fire...Looks like one of the coils..May as well change all of them as once one goes...86K so they are most likely the original ones.Bosch coils are 20.00 each so Im gonna swap em out.Cheers,PGM
Hi, I’m having the same issue, do you know if that cap also fits into 328i 2009
This scared the shit out of me and i thoight it was the belt. God damn valve cover
So you bought a whole new valve cover. Did it come with the gaskets and pcv? The link to ebay doesn't work. Or does everything need to be bought separately?
Hi there, I replaced a water pump for my f10 535i xDrive 2012 and did the bleeding and everything worked fine, few day later vehicle started overheating, I checked the water pump by activation method and didn't seem that it works! Diagnosed the system and got the code 20A909 ! What can the real reason be for it to stop functioning?
I did this but It's squealing again after one week. What could've made it go bad again so fast?
Hi, what is the Brand that you used with the valve cover? Thank you
THANK YOU!!!!!
Vehicle Virals, Do you happen to recall the brand of Valve Cover you picked up as a replacement? I have found a few on Ebay for cheap but would like to pick up something that is quality. How has it held up?
DONT BUY ONE OFF EBAY!! You need to get the genuine bmw one or you will be having troubles sooner than later....Cant play cheap on valve cover
I’m sorry but if I’m not mistake then I believe this job should be a factory recall. It’s free replace. You should check with your local dealer.. thank you for make a such great video.
I looked into that but wasn't able to find any info, thanks for the tip anyway and glad you liked it.
Vehicular DIY : I looked so many DIY video about BMW, your video is the best so far. Thank you for putting so much effort for all these videos. PLEASE keep up... GREAT JOBS!! I really don’t know how to take care my BMW without you.... 😂 😂
Any further information on this? I have a 2011 X5 N55 making noise, I replaced the PCV by cutting it off and that seemed to fix the problem for awhile but the noise is coming back. Just got a quote today for $2k for the rear main seal replacement.
Good shit 👍🏾
How to disable auto start?
Your education is really excellent and it solves the problem, but my problem is beyond this and the reason is the place where I live and the country where I live, which has a law similar to the law of the jungle. My compatriots trample my fellow countrymen and cause my country to be embargoed, that's why cars and spare parts and all the things people need are very expensive or rare. He found a valve door in the parking lot and the ability to buy a valve door that costs 500 dollars in my country has disrupted my life and I am slowly getting depressed. 😭
has the KGE membrane repair not worked ? Why ?
2008 bmw 550i n62 4.8l can you update , program my car over the air , ty let me know sorry to ask
How is it holding up? I want try this method
Damn just bought my 2011 535i and it’s making this sound but it only happens after I rev it in idle tho
My E70 with N55 engine is also producing the same squealing noise and appreciate your video very much. But unfortunately the part number that you show in the video is referring to the whole cover not just the PCV. Where can I buy the PCV?
Found it on ebay.....lol..
How did you no it was bad
Awesome work! How’s the eBay cover working so far? I’m getting ready to do this. I just have a leaking gasket, PCV is fine for now but might as well swap the whole thing.
Thanks! So far so good.
@@VehicularDIY Hi there , wateched your video , great work man, was wondering if your aftermarket valve cover is still ok , no problems in 2021?
As we speak I have my 2007 x5 valve cover off and I purchased an after market one , I didnt have your issue , my valve seals were leaking and oil was getting into the spark plug chambers and cause a misfire, so I decided to buy the kit with valve cover and seals from amazon.
Very inexpensive , I am just a little leary about the durability and how long it will last without cracking etc...
So I wanted to know if your valve cover is still going good?
I have never had an issues with after market parts on my BMW so far, but I wanted someone else opinion.
So I had my Valve Cover replaced by a local mechanic and then it started making this noise a few months later. What does that mean?
The link for valve cover does not work , is there another link ?????
eBay link is broken. What brand was that aftermarket valve cover
Hi Bud... question. have you installed a oil catch can on your N55, i see lot of folks are doing it on N55 and N54 motors... any advise?
I didn't, I'd say the N54 benefits from it much more than the N55 but it's a good upgrade either way.
can i just drive without oil cap . Then no noise and solve the problem
Can you do this on E60
Will this problem cause your car to be thrown into limp?
Would a vented oil cap solve this issue as well ?
O my lord this is my issue thanks alot will this throw a code?
