BMW N55 Squealing Noise Fix DIY

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.

[@AdrianSinner97]

am struggling to understand that kind of noise since one year now ad drove me crazy ever since. gods bless ya for this

[@philipblaschke3610]

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.

[@qitianzhang3641]

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 now experiencing the same exact sound on my 2013 bmw x5 xdrive35i at first I thought it was the idler pulley and tensioner which I change out with a kit from bimmerworld, but there goes that same exact noise again, thanks for sharing.

[@markwalker3499]

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.

[@kishorham]

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.

[@wadeconner3200]

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!

[@kishorham]

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.

[@wadeconner3200]

@@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!

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! ;)

[@MrLaloman18]

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...

[@philipblaschke3610]

I agree with this as well if your new cap does not doe the trick. This will do it.

[@markwalker3499]

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.

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).

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!

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.

Hi, I’m having the same issue, do you know if that cap also fits into 328i 2009

Supposedly when the valve goes bad the pressure builds up under the cover and that is the true cause that creates the infamous valve cover oil leaks.

Do you know if that pressure is bad or damaging?

[@mircebob]

Just a tip for people replacing just the pcv valve, make sure you put only small amount of glue on the outside of the housing not on the cap, same spot as per the oem valve. Too much glue will cause the new diaphragm to stick to the new cap which will close the valve and not operate correctly. You will end up hearing the squealing sound again like in this video as the diaphragm can not move freely.

Amazing tip: Soak the "valve cover gasket" that comes with the whole unit un 303 Aerospace protectant solution (PepBoys & amazon has it) for a whole day prior to installing and that gasket will last a lifetime as the 303 will penetrate into the rubber and will prevent that gasket from drying and cracking in the future!

How is the valve cover holding up today? What brand did you get?

[@f30_brandon17]

Mine usually comes about after cold starts letting the car warm to temp an then getting into boost. I can shut the car off then back on and goes away. I will say when this noise is present my boost drops drastically.

Where’s the long please ?

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?
