[@lmc333]

Thank you for taking the time to explain, unlike other videos that made it sound easy when it is not. Thanks Man!

[@JohnsonMotorsports]

Glad it helped! Let me know if you have any questions.

[@bsearzz]

thanks for the video! i had my valve cover gasket replaced a few months ago because of the squealing but it recently decided to start doing it again. Im going to try this today

[@JohnsonMotorsports]

B Sears It’s worth a shot, however I ended up having to replace the whole valve cover. If you checkout my intake valve cleaning video, I do a review of the unit I picked up and provide a link to the part.

[@busnezz89]

Grant that's true.. Keeping your intake system clean makes a very smooth ride.. I clena my own every 2 months depending on how much I'm driving.

[@JohnsonMotorsports]

That’s a good idea.

[@mtthomas5049]

Grant, Thanks for the PCV help….my second attempt worked great based on your help….smooth idle, and 2.5 additional MPG ….✅✅✅…..thanks a ton

[@JohnsonMotorsports]

Glad the video helped, but keep in mind this fix only helped me for a couple of weeks. I eventually had to replace the valve cover. I picked up one for $100 and the quality was great!

[@Aku-sm6xx]

Did you change the valve cover too or just the pcv cap?

[@BmwFinatik]

Another good diy fix I’m glad I found out about this replacement pcv valve cap . I’m getting that squealing noise and was about to have to replace the valve cover and I’m dreading that cuz I had a oil leak about a year ago and replaced the valve cover gasket-I 11:18 snapped one of the valve cover bolts in the process so will probably have to tap n die to extract it. I just do not want to do that job again any time soon But I am almost positive I need a new valvetronic/servo motor anyway because I am getting codes for that as well so unfortunately that is something I am going to have to take on Another great video my guy 🤘 & wish me luck 🤞

[@JohnsonMotorsports]

Probably best to just pick up the Valvetronic kit which includes the Valvecover gasket and just knock it out. This fix worked temporarily for me until I could replace the Valvecover.

[@Dejan_Beganovic]

What code are you getting exactly. If it's a deactivation too frequent code. Doesn't need replacing. Just needs relearning with a scanner

[@trevorschnedler4472]

Sorry to ask, this is a dumb question. What was the car doing incorrectly for this replacement to be necessary? Thanks!

[@Sebastian-p6k9k]

Hey. Could you make a video of what part they mean with the latest recall of BMW about drops of liquid to the coolant pump connector?

[@shawnmacarthur5464]

Great Video. Gonna tackle this on my 2015 M4 tonight.

[@JohnsonMotorsports]

Nice! Just keep in mind this is a temporary fix, I still replaced my Valvecover to correct the issue.

[@mohammadalam7245]

Hello. I have a p147D code and I’ve replaced most of the parts regarding that code and the engine light is still there. Will this help get rid of the code?

[@JohnsonMotorsports]

Sorry, I don't have the information. What is the p147D code for?

[@MWS1960]

When you put the cap on before pushing it into position…start the engine and it will suck it into the right position and ensure it’s tight. Snap the cap on and your good

[@JaimeAlvarez-k5q]

Would this cause my car to vibrate at different speeds like a vacuum leak? Some times around25/30mph and 45/50mph, unless I accelerate it hard. I have no codes coming up or a check engine light.

[@JohnsonMotorsports]

I can definitely feel like a vacuum leak, however I don’t recall vibrations.

[@Ashley_van_Schooneveld]

I have an EWG N55 with 115k mi still on the original valve cover and PCV. I wanted run a quick test by slowing removing the oil filter on a fully warmed up engine at idle and I when removed the car I felt air being sucked in the crankcase with with a psssshh sound then engine idled rough for a few second until I replaced the cap. I drove the car the next day, there was no CEL but I noticed about max 2 teaspoon of oil on the driveway in only one spot. I typically don't burn any oil between OCI, no rough idle, no smoke, no CEL and this engine pulls hard since it has MPPK retrofitted. Btw the valve cover and gasket are scheduled for replacement since I notice some oil sweating in passenger side of the gasket towards the back. Any advice on that?

[@JohnsonMotorsports]

Yeah, I would definitely replace the valve cover. Removing the oil cap on our engines will always result in the car stumbling and a rough idle. That is due to the vacuum system being built in the valvecover. Replacing the valvecover may also fix the oil leak, however you may want to inspect your oil pan gasket.

[@vicwahbyphotography4866]

Hi Grant. As much as I liked your video, the diagnosis producing a failing PCV valve would be very helpful. As you say in the comments below, you eventually replaced the whole valve cover, but you don't actually say why. So, as us DIY'ers look for solutions, it's key to get the diagnosis correct before jumping to the cost saving fix. In this case, I think you should tack-on some text saying you eventually replaced the valve cover. I do have a question though... If the PCV test OK, but the valve cover needs replacing, might it be OK to replace just the valve cover gasket? Cheers, Vic

[@JohnsonMotorsports]

Thanks for your input. I will update the video description. As far as the PCV testing good and just replacing the gasket. From what I have found it is more efficient to just pick up a replacement Valve cover and gasket and replace. The run around $100 online for a non OEM unit and they are almost identical. In most cases the plastic Valve cover has also got gunked up in the vacuum ports or has an internal vacuum leak between chambers that will continue to cause issues.

[@mikeeonfiya]

I’m replacing this today - thanks for the heads up! Was burning oil, low coolant in reservoir, and a lot of white smoke from exhaust upon starting/accelerating from a stop, is indicative of pcv/ccv valve? Is it also called the oil separator? Thanks again!

[@ademfeka9633]

Did you also lose power ?!

[@HowToDoitright]

hey bro ...i replaced my part but i dont think that resolve anything. i wonder if i should just replace my entire valve cover. i see you replaced yours with the one on ebay....how is that holding up for you and did that fix the issues with your car?

[@JohnsonMotorsports]

Yes, I think you may be in the same situation and need to replace your entire valve cover. When you have a chance check out my video on Valve Intake cleaning. In that video I show you were to check for an internal vacuum leak that could be your culprit. How many miles are on your car?

[@HowToDoitright]

@Grant Johnson i have 79k on mine....ill check out your video now..

[@jonrandall5490]

Nice video, Grant. My friends have a 2014 X3 35i F25 with N55 "twin scroll" turbo motor. They have 123,000 on the clock, and have done some oil changes, but not enough, my opinion. Their car has some fairly serious oil leaks. Most of it seems to be dripping down near the back of the valve cover on the passenger side (USA car) onto the exhaust of cat. conv. We recently replaced the valve cover gasket, but it still leaks in the same spot. We used a Mahle valve cover gasket. We are getting this much mentioned 101F01 code and mainly have a rough idle now. I'm wondering what to try next on their X3. The rough idle is often caused by the PCV valve on these N55 cars ?

[@JohnsonMotorsports]

I had to replace my Valve Cover to due to the PCV valve. The fix in this video on helped temporarily. I assume you will need to do the same. The new valve cover could possibly fix the oil leak issue as well.

[@purityautohygienics]

Possibly check and clean or replace Vanos Solenoids for further rough Idle and “timing” symptoms. The oil leak is a different story… not really sure there.

[@chrismanb]

How did alumin foil taping it make the chipmunk sound go away?

[@JohnsonMotorsports]

It was actually replacing the diaphragm underneath and it was only temporary. Best to get a new Valvecover.

[@zeroalcohol]

Did the fix worked at the end?

[@JohnsonMotorsports]

It worked for a few weeks, the. I had to replace my Valve cover. Mine was too far gone.

[@dgoldman2846]

thanks for the video, I have a Permanent code 101f01 on a 2011 535ix, Replaced the boost pressure sensor and it did not clear the code. I guess this PCV "Cap" is the main issue for the permanent code on these cars?

That’s definitely a possibility. I’m not familiar with the 101f01 code. How many miles are on your car? What maintenance has been done?

D GOldman if your valve cover hasn’t been replaced in the last 75k miles, I would definitely start there. I picked up a new one for around $100. Check out my video on intake valve cleaning, I have a link to the valve cover I bought.

Can a bad PCV valve make your car smoke out the exhaust I have a 2012 BMW 535i f10 I thought it was a bad turbo I replaced the turbo on it still smoke sometime

[@JohnsonMotorsports]

Not typically. It will usually just mimic a vacuum leak.

[@dominikmartinez4748]

Hey quick question have you fixed the smoking problem??my 2016 340i started blowing out huge clouds of smoke out the exhaust i just bought the car 6 days ago so im not really that knowledgeable of the engine itself i took it to the shop already im just waiting on the diagnosis so i would really like to have an idea of whats going and ofcourse slowly get into DIY mechanics on bmws...i would really appreciate you letting me know what worked out for you👍👍

[@juanponce1078]

Hey brother, you said tht the only way this cover would stay on is by securing it with the tape... it won't stay on with just the silicone

[@JohnsonMotorsports]

Mine wouldn’t, but I only used this temporary repair for a week or so, until my new valve cover came in.

[@rcadventuresoffical]

How long did you let the rtv cure before you drove the vehicle?

[@JohnsonMotorsports]

I let mine cure overnight before driving. Probably a little excessive. Although, this repair only worked temporarily. I ended up replacing the valve cover with an eBay one a few weeks later.

I used my high speed cutoff wheel to remove the cap. Cut a few reliefs and then used a flat head screwdriver to carefully pry it off.

[@eddieshirazi2179]

Hey brother, can you put a link on where you bought the part? Based on my research there's a company in Ukraine called vanos-bmw that sells this part as a repair kit for $20 + shipping; also Ebay has one for under $20 coming from China. Your thoughts.

I just started having issues again with the engine whistling from one of the seals, as well as a lean bank code, but I think I have a bigger issue with my valve cover. I will update as soon as I am able to determine the culprit. Thanks for checking out my videos!

[@eddiaz2956]

[@spadethebarber8696]

I just changed my valve cover and its still running rough and making a noise

[@JohnsonMotorsports]

What type of noise? Whistling?? If the Valvecover was bad for a long time. You may have damaged the front main seal and it could be causing a vacuum leak.

[@spadethebarber8696]

Yea the whistling sound. Turns out buddy only changed the gasket for the valve cover and not the cover itself.

[@JohnsonMotorsports]

Gotcha. Yeah, you will need the whole Valvecover replaced since the PCV system is built into the cover.

[@silviataylor92]

Hi, My bmw E83 crankcase vent valve went bad with pressure in engine & blow out my valve cover gasket. Do you think it could have damage any other seals?

[@JohnsonMotorsports]

Honestly I’m not familiar with your engine, but my buddy that works for BMW suggested performing a compression test. Because vent valves tend to fail simply from plastic dry rotting. If in fact it AND the VCG failed due to high crankcase pressure, that is a very troublesome situation.

[@foxkris]

[@nikosusa]

[@KimboDogg07]

This is worst shit you can do... Being a BMW ASE Certified technician these types of videos bother the shit out of me. It steers people in the complete wrong direction, wastes money and causes following issues to derive later on. On this system you should never be replacing just this part separately, the entire valve cover needs to be replaced. Yes the entire valve cover, yes just because the PCV is bad. Sorry but that’s the perks that come with owning a BMW.

[@chucke3305]

What caused the diafram to burst? I tried the quick fix and it only worked a week. I don't want the new valve cover to fail also. Can you point me in the right direction please.🧐🤓

[@JohnsonMotorsports]

I think the issue has to die with age. Just the heat cycling overtime makes the plastic parts brittle and they eventually crack. A new valve cover is eventually needed.

[@mihalym.6876]

Got a reply typical for ASE: telling nothing. If you are so proud of being ASE than explain for us how the whole PCV system is designed, including all the valves in the VC and PCV pipes, possible malfunction points, etc. Instead of that the result of all of your ASE education tells us: replace the VC. Sorry to brother you, the administrator at the BMW dealer desk can tell the same without any ASE paper. If you do not want or have information to share to help DIY guys to repair their stuff than do something else and do not waste anybodies time.

[@drdavetexas]

The WORSE shit you can do is to pay BMW $200/h for very simply repairs. I have the money, that is beside the point many who drive a little older BMW do not. Additionally, many of us who work on cars like to solve problems & are proud of the solutions we find. Lastly, the primary thing that separates a mechanically inclined "DIY " individual from a BMW mechanic is access to information which BWM attempts to lock down. Also , you speak as if OEM BMW valve covers are superior products, which most of us "DIY" aka BMW owners have disproved that myth on "most common replaced ( problem ) parts.
