From a viewers perspective, being able to watch you carry these works out would be a huge advantage.

[@AdrianJayeOnline]

I guess because we all know how to attack things with a chisel and hammer LOL, don't need to see 10 minutes of that

[@uswwt]

Great video. I need to replace the valve cover on my 11 528i soon. It's leaking oil into the spark plug wells. And a couple days ago it made some loud whistle noise. The PCV valve is probably bad.

[@mcgusto82]

I just replaced mine in my e83 07 X3. I went EPOXY, and I installed the spring. I wouldn’t do the RTV sealant as there’s more room for error. The epoxy dries in less than 15 minutes. If you remove the cowl, you have plenty of room to work it. Those tabs you see on top, if those line up with the vertical lines of the engine, you’re fine. Unfortunately for me, problem only got slightly better. The rubber was ripped, but it’s still misfiring. I’m doing the VANNOS check valves next. Which I unthreaded but won’t slide out of the block. I bet they are filthy.

[@mcgusto82]

whacky pax - yeah. They were filthy. They had metal in them. Sold the car for 1.5k. ☹️. Btw, I got those check valves out by cranking the engine with them loose. They bursted out and spilled about 2-3 liters of oil. My conclusion, old cars suck ass.

[@jacintogarciarivera5372]

Con la nueva pcv,se añade el muelle de la antigua o se deja sin muelle?

[@waileongwong4974]

Hi guys, how's the e46 1.9L with model m43b19 1.9L? May know where the ccv or pcv valve located on my machine? Is it possible modify with install the catch oil tank?

[@sakchaisajjasuwan2635]

Do you put hose in to ccv yet

[@allanconsuegra3815]

I'm not sure if you'll still reply, but does a hose connect to that valve? I see there's a piece that seems like a hose connected there

[@WarpDriveM]

There is no hose in there is just a release cap but you are right it looks like that 😅

[@atkmedia3006]

I have the same problem with the cold start by my n52 330i for 5 seconds that I have speed fluctuations as with you in the video even worse, I have cleaned the solenoid valves but no improvement, should I also change this membrane? thank you from Germany :)

[@WarpDriveM]

In my case solved the problem. But I've ended up buying a hole new engine cover because I couldn't really glue it perfectly on the cover and I've cleaned the non return valves as well. I have a video for that as well

[@atkmedia3006]

Warp Drive M I've already seen the video with the valves but you had no improvement there? I don't want to spend money unnecessarily. Your video looks very helpful. I've had the problem for over 7 months 😔

[@WarpDriveM]

After cleaning the valves and the new cover everything was like new. Not a single problem since. I hope this helps 🙏

[@atkmedia3006]

Warp Drive M So now I have to completely clean the valves and get a new valve cover where the membrane is already integrated?

[@mrallande105]

Taking that cover off is a pain. Bmw stuck the engine a good amount towards the firewall. Wish it was forward more.

[@WarpDriveM]

Yeah I feel the same. But if you remove the wipers and all the plastic parts you have room to work but still tight.

[@jorgetovar8206]

Is the nipple on the ccv or pcv blocked off ? Mine has a hose that ran to the Throttle body

[@WarpDriveM]

That is a vent pipe, in some models goes like your case to throttle body or directly out

[@boratkhan]

I have owned F10 5 series 2011 (n52) for the last 5 years and its been good to me. Issue and Symptoms: Every time I start my car it will start normally and in 5 sec after that I would hear a short hassling whistle and it would start to vibrate for 6 to 10 sec while the rpm needle would remain below 1000 and then it would pick up the RPM and stop vibrating (not completely you can feel light vibration). And driving if i step on the gas it somtimes delays in reacting and if I do stop at the light you can still feel is vibrating. I'm also getting some smell from the exhaust pipe but no smoke but its a strong scent. regardless of if the car is cold or hot if I start the car is would act in a similar manner. I believe it could be a vacuums issue (not sure though) Kindly assist me please

[@toqrulqeribov2043]

i have exatly same problem did you solve the problem?

[@mattporto4530]

I have the same problem. Could it be the PCV valve? Or CCV?

[@spuky02]

I'm one leg too and i'm fixing my 2011 325i, no current on back up sensors, radio and certer screen for all the infomation, any idea?

[@WarpDriveM]

This sounds like a fuse box or junction box problem. You can try to move the parts from glove box to see if something is starting to work

[@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?

[@WarpDriveM]

The hose from the vent goes under the intake in to an oil separator.you might want to check the intake as well but usually just just the engine cover is starting to leak. The valve regulates just the pressure from top of the engine....so nothing to worry about

[@silviataylor92]

Thank You, Friend !

[@arebelfromhell]

is there suppose to be a hose on that ccv valve? or does it just release to atmosphere?

[@WarpDriveM]

No hose, won't release to atmosphere because of the membrane, the hole is there just for membrane to be able to move otherwise will create vacuum

[@PrinceZariyab]

I have 2005 , 320i and have same smoke problem, i toke to workshop he check and said need to change the engine. 3 mechanic said same so i decided to change engine and its has same problem. Too much Smoke like before. What to do ?

[@WarpDriveM]

If the problem is the same....its simple...it's not the engine 😈😬. You have to check you Katalysator, exhaust, turbo (if your car is equipped with) intercooler piping, intake, egr, agr, all the recirculation exhaust system,aux air pump if your car has one....and so on

[@jochenb7653]

you can almost feel how the car is shaking if u pay attention how the idle is running! :))

[@WarpDriveM]

Ha ha

[@danil1417]

the car is undulating, the computer indicated a poor mixture, where to start? it is possible that I do not have catalysts

[@trade1713]

That looks painful to change the whole cover after the first attemp to fix it. Did you ever have problem with hydraulic lifters clunking/ticking after first start in the morning on your model?

[@WarpDriveM]

It is painful to change that cover...but if you take your time and remove everything even the wipers and the cawl you will have enough space. And I had some problems with the lifters but is all sorted now. It's a commune problem on this model

[@trade1713]

@@WarpDriveM how did you sort out the lifters?? I tried all kind of products for quiet lifter, none of them works! What did you do? It's driving me crazy! Mine clunks worse then diesel before it warms up and stops.

[@WarpDriveM]

@@trade1713 in my case the oil channels were blocked. I've opened the engine cover and oil pan and cleaned everything. After that everything was fine. It was clogged almost everywhere. I have a video about this on my channel somewhere

[@trade1713]

@@WarpDriveM I'll have to check out your video. Thanks mate, you're champ!

[@naderg2]

For lifters tick, rev the rpm at 3000 and hold it for 2-3mins. This will bleed the system and the noise will go. I do this after each oil change

[@AhmedIbrahim-lf1vv]

Is there a hose that connects to the pcv? I just bought my car, and found that the pcv nipple is not connected to anything. Thanks

[@WarpDriveM]

No. It's like this. No hose...

[@theamerican7080]

One port is usually capped off.

[@bgubs07]

If you still have the car, take a look at the hose connecting your intake air filter to the throttle body. If there's a little nipple on the black hose then that's where your pcv hose connects to

[@user-dd4hh7nz7j]

is rough idle disappear if AC turn on? I have the issue only when idle without AC. I want to make sure before change the CCV. Thank you from Indonesia.

[@Everybodyshinetogether1]

Same thing have u replaced this?and did u get a lean misfire code?

Did it solve the problem?

[@firasalwakeel5365]

The time you have installed it, at low idle did you get like engine vibration? I have replaced it and the engine stopped burning oil however, at low idle like 600 rpm. I have terrible vibration, and on warm start up I have got rough Idle. Thank you

[@WarpDriveM]

That means that you have a vacuum leak. Maybe the valve is not sealed properly or your hose from the back from cover is not plugged or somewhere else is leaking vacuum

[@firasalwakeel5365]

@@WarpDriveM Thank you, I will check it and I will let you know. I think I am better of just replace the whole cover.

[@coolbema]

@@firasalwakeel5365 best bet is to replace the whole cover it comes with built in CCv..by the I highly recommend you to replace eccentric shaft sensor same time along with rubber seal. It will be one time headache and avoid you for future trouble.

[@z4funkdreamer986]

hi i have also 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 as it is a bmw part it must have a genuine reason to be here please let me know thks

if its not damaged put the OEM cap back on

Can you give us an update if replacing the ccv helped you with the problem? Thanks

[@WarpDriveM]

That solved my problem but I didn't like it because it wasn't straight and not fully pressed. I didn't want to risk after a few weeks or months to have it redone again so I've ended up removing the engine cover and in the next video you can see the end result. BUT changing that valve it resolved my idling problem!

[@chrsbs]

Warp Drive M nice, I will try that this week. I did replace the vanos filter they where really nasty. Thanks

[@WarpDriveM]

If you are replacing the valve do not use the spring anymore because it won't seat properly because of the spring pressure OR put something on the valve to keep it pressed till the glue dries.

[@chrsbs]

Warp Drive M I just order a new valve cover with gaskets & bolts.

[@WarpDriveM]

@@chrsbs best choice ;)

[@z4funkdreamer986]

hi i have a z4 e86 with n52 engine 2007 model , after 10/2006 n52 has not anymore the ccv (please check real oem) but wondering wich n52 do you have as it should be same as mine and impossible to find this part on realoem please give me the bmw part number of the idle valve thks

[@WarpDriveM]

The idle control valve refers to ccv (crank case valve). The n52 doesn't have idle valve. It keeps the idle with the valvetrononic motor in conjunction with vanos. The valve is glue to the engin cover. You can replace it or you can replace the hole cover. First you have to be sure that that is your problem. Scan the car first

[@z4funkdreamer986]

Warp Drive M thank you very much i have a rough idle but seems it come from vanos filter i have to clean them but the problem is i have a leaking between transmission and engine and many people say it is due to bad pvc and accelerate pressure on the RMS that is why i would like before remove transmission check this valve on the cover gasket

[@diseld7956]

Bro I just replaced crankcase valve , everything went good so far but I'm getting p0012 code why ?

[@WarpDriveM]

You have to check if you plugged the sensor from the front of the engine cover correctly

Did you figure it out bud?

[@pgdmed]

I’m confused, I thought the ccv was the one under the exhaust manifold?

[@WarpDriveM]

On this model the ccv is glued into the engine cover and is connected with the "pcv" from under the intake manifold (not exhaust manifold) with that hose that comes out of the engine cover

[@GPTSkills]

The 1st gen N52 (with magnesium valve cover instead of plastic) has the ccv under the intake manifold

This is a "hmmm ok" fix, I wouldn't do that, too much danger of busting something, also having to silicone a new part in... do it once properly, these kinda botch jobs "could" cause more problems if you get unlucky, the proper fix is to replace the valve cover

[@iamher6422]

That has to be the dumbest design ever! There has to be an easier way to remove that valve.

[@glenglene8473]

Don't waste your time replacing the PCV, won't fix the problem. I talked to a few people including myself, replacing the PCV won't fix the problem.

why. how can you tell? my car have excess oil out of the pcv on the valve cover. especially under hard acceleration. what should i do?

​@@YorumiTechReplace your valve cover.

[@larryjohnson8168]

So the only way to replace it is to break it off? How stupid is that

Normally you have to replace the engine cover completely

[@stevenrogersfineart4224]

Such a garbage design. WHY does it have tabs if you can't ^@*$$ remove it ?!?!?! :P

[@warpdrive_m]

I'm pretty sure that if you remove the engine cover and change the valve on the bench it would work! By the way what kind of accident did u had?

[@WarpDriveM]

For sure on the bench I could probably do it right but I wanted to avoid removing the cover and I've ended up doing it!?! 😂 about accident....something really stupid! I've just felt on the street while crossing on the other side and I felt wrong on my right ankle and busted my left knee. Like I've said stupid accident and I can't walk for 3 weeks now....😥

[@mcgusto82]

No need. Use epoxy, hold it for 5 minutes. If thinking you’ll still own it in 10 years.. you might be thinking poor. And by then, the valve cover might be leaking anyways so you’ll need to replace seals. Mine is 13 yrs old with 155k miles. New Pcv should hold another 10 years.
