Interesting video and I'm going to give it a try. One thing you might add to the instructions is that the computer memory keeps a record of the engine fuel and air ratio and it "learns" and continues to try to mix as it was before you changed the part. To reset this memory, get in the car and put it in the "on" position (not starting it up). Hold the gas pedal to the floor for over 60 to 90 seconds. Release and shut the car down completely (lock it) and let it sit for a period of time. The car will then start to learn the new situation with the new part.

[@HowToDoitright]

Thanks for the reset info. I did the adaptation reset via software. But honestly after years of making this video and my experience this may not work. Probably better to replace the entire top valve cover.

[@BurrNinja]

Completed job. No check engine light. Idle doesnt search rough anymore. Will post in future how car acts in warmer weather cause thats when it was at its worse.

[@eddieshirazi2179]

Has your pcv been holding up from 10 months ago - any issues?

[@JAydUBr6]

Thanks for showing what it sounded like.

My e90 is making a loud shinning noise with error code 171. When I release the oil cap, there's lot of suction and resistance to release it and once the cap comes off, the sound disappears. As soon as I put the oil cap back on, the loud noise comes back. What could this be? The code from Autozone says it's the MAF but I changed that 6 months ago and it wasn't needed so I returned it. I also have ISTA but I'm not sure how to use it for this.

[@kishorham]

I did mine 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.

[@HowToDoitright]

You are right. In my case I endup replacing the cover and then decided to sell the car. After about 6 months the guy who bought told me that the engine seized up. I hate these cars. Never buying a BMW ever again

[@thehobbyist5292]

replace the whole cover. its only over 100$. the original pcv was plastic weld, not just adhere.

[@BigUriel]

I'm 99% sure that the vaccuum when you take off the filler cap is normal, that's exactly how the PCV valve is supposed to work it uses vaccuum from the intake to open the valve and draw in blow by gas. The sump should be under partial vaccuum at all times when the engine is running. If you see no vaccuum at all when you take off the cap it would indicate the PCV or the non return valve are blocked.

[@BriceGibson]

This was happening to my car last week. It was a piece of sponge in the fan to the motor. I took the blower motor out, cleaned it. Now my car wont start😫 but that sound is gone from the motor. Id rather keep the noise vs not having s running motor.

[@HowToDoitright]

I bet you blew the fuse that I blew on mine. There is a fix on my channel for that.

[@evoquesquad2015]

How long did it lost

[@MrArcsifun]

I did this, PCV valve change, i had the same old PCV like in this video, but the new one is not working for me, i had brutal oil consumption after the change...

BMW 535i 2011 to 2016 n55 engine Valve Cover part: # 11127570292 Comes with all build in screws. All valve cover screws need to be torqued to 6.2 lbs. Also highly recommended: Get the Valvetronic Actuator Seal: # 11377502022 along with the valve cover.

[@hellanaughtyy406]

After that job did you see any oil spitting out of the oil cap at idle when you took off the cap ?

[@HowToDoitright]

Not at all

[@StillBrokeOff]

i did

[@eddieshirazi2179]

i've got an e90 2011 335i N55 same problem; can you put a link or help with where your purchashed this CCV kit? also, how has it been holding up since?

[@Trump-The-GREATEST]

This is a total waste of time and money! If you are having CCV problems you MUST change the whole valve cover as it also has delicate vents inside that also get clogged and fail making this Micky Mouse bootleg job a giant FAIL! Valve Cover Replacement for the F10 n55 engine is just $90 - $130 total OE high quality on Ebay or Amazon! Replacing the Valve cover brand new will fix lots of issues, trust me! Its worth it! Stop going the lazy route, you will pay for it ... 😂

[@eddieshirazi2179]

@@Trump-The-GREATEST I did this ccv change and surgically removed the oem ccv and used JB Weld to attach it in place. I was careful to use it around the circumference while not putting too much as to potentially clog the membrane and diaphragm. It has been a week and I still get a howling sound + erratic idle at cold start only. Once it is warmed up, it runs fine. Prior my car was stalling; now I can drive the car fine (post warm-up). Note this is a short term fix and I will sooner than later have to install a new valve cover to have a smoother start at idle and remove the pestering howling. Please not that this part for

[@derekkchung]

It is troubleshooting that counts. Now u have spent time, effort, and money and the valve is actually not defective.

[@Jet3ch]

Can the fire test be done before or after warm engine?

[@HowToDoitright]

So after my personal experience I suggest just change the entire valve cover man. I honestly don’t think it worked at this point. I endup changing my valve cover. I have videos on it on my channel F10 playlist.

[@user-kg3gc1se4n]

may I know what is rear main? I followed your way but still squealing noise..

[@BurrNinja]

@@user-kg3gc1se4n I ended up replacing the whole valve cover. Theres more to the pcv system then just the circle diaphram you see. Theres paasages built inside the cover that can get caked of oil causing fsilure. After I change the cover myself I still slightly hear the rear main seal but it shouldnt cause anymore damage to it. The rear main seal is a rubber O ring that sits between the transmission and engine to seal off the input shaft to transmission.

[@user-kg3gc1se4n]

@@BurrNinja thanks for detail explanation. if so do I have to take the transmission out to solve this issue?

[@florenbaron7111]

When you sold that car you better have told the buyer about that problem. I hate people without integrity.

[@HowToDoitright]

Thank you for the lecture but It’s dealers responsibility to check. Not mine to tell every detail about the car to the dealer. Not like they use it for themselves. Most likely they auction these cars.

[@BurrNinja]

It idles better but still hear squealing. I'm gonna buy a new valve cover plus get my rear main seal done too.

Oh damn. Let me know how much it cost to do the rear seals. Post a video of you can

did it fix the squealing?

You have to drive it about 100 miles after you put new pcv to allow the rest of oil goes out of the catalytic converter

It blows white smoke? Is that normal after?

I have changed the pcv valve, but I still get a screeching sound when the engine is warmed up. Can you help me? I am at my wit's end.

Bro I realized later on but the pcv valve replacement didn’t last me more then a few months. Endup replacing the entire valve cover. See a video I posted on that. Bought one for 100bucks on eBay. My video shows detail comparison and installation. Hope that helps you.

Heat it up only you don’t need to cut it

Too much heat will cause damage to your cover. Cutting is much safer

[@evoquesquad2015]

Is it still working

[@HowToDoitright]

Yes working great but if I have to redo it I would go with a new valve cover

[@evoquesquad2015]

So why wood you get a new one

[@battersf4153]

You know you can just pop it off right!!!!

[@HowToDoitright]

Pop what off?

[@battersf4153]

@HowtoDoit the pcv. Unless it's literally glued on. But you should be gluing anything on with jb or anything if it's meant to be popped off. At that point whoever is doing this might as well get a whole new valve cover.

[@HowToDoitright]

Good point

[@indyguy5570]

The pcv is plastic welded on at the factory, it will not just pop off because it is not considered a replaceable part. In true BMW fashion they expect you to replace the entire valve cover since it involves more than just the pcv valve. This is a tempting short cut and may fix the issue for a few lucky ones but most have the same problem return after a few days and end up having to replace the entire cover to fix it correclty. I am all for saving money but sometimes there is just not a short cut.
