Hello is the diafragma in the ccv stuck in the open position ? So the intake sucks alot of air ?

[@ReCverin]

There are lots of smart asses posting comments here, but this is a very useful video that shows what to expect when diagnosing the CCV valve membrane/diaphragm failure. A slight vacuum is normal, but this extreme vacuum is not. CCV failure is a lot more common than many people think; on the models listed here as well as every other BMW manufactured since the early 90's, as well as the VW 2.0 TSI, and I'm sure there are others. P0171 and/or P0174 are common. Other symptoms can include whistling/screeching/howling sounds of air being sucked into the crankcase, sometimes through the oil filler cap or valve cover gasket, sometimes through the front or rear crankshaft seal. On a VW 2.0 TSI, this problem can, and often does, pull their stupidly designed, cheap rear main seal loose, meaning you have to drop the transmission to repair the oil leak. This has also occurred on BMWs although less frequently. There is a TSB describing replacement of the front or rear main seals on certain BMWs era 2009-2011 due to CCV failure. Thanks Bimmer Zeit, ignore the smart asses.

[@BIMMERZEITT]

Thanks for the helpful comments bud, I appreciate it. Yes, it is good to mention that this CCV failure is a common cause of the P0171 and P0174 codes. On this car the vacuum was so strong that it put hairline cracks in the valve cover, further leaking air and causing lean codes.

when buying a used one with no history of maintenance you must methotically replace everything and start a new history, Thats why you should get it dirt cheap. you should turn your own wrenches and get INPA or some software to monitor its health regularily. They are attention whores and high maintenance but they also perform!!! if you're into gassing up and oil changes only, they are not a good car.

My 46 does this, I replaced the ccv for a catch can and it still pulls a strong vacuum. It doesn't use any oil whatsoever now and runs much better.

[@BIMMERZEITT]

Interesting! I haven't heard of that before. The CCV system is one of the most difficult DIY's on an E46, I have done one a few times on our old 325xi. I hated that car!

[@CableWrestler]

+BIMMER ZEIT You're right, it's a right bitch of a job. Very time consuming and fiddly, but I left this particular one in place. Basically, you block off the dipstick return pipe, install a bit of 1" pipe from the rocker cover where the VANOS is, put in a reducer to 3/16, and the run that pipe to a catch can. The return pipe from the catch can then goes to an outlet that is normally blocked off on the inlet manifold right near the firewall on cylinder 6 (this may or may not be on the m52 engine) It works very well, there's not much that can go wrong with it as long as quality parts are used. All in it cost me about £50 (~$70?), and half an hour to install. For those reading with a similar CCV problem, at least you know there's a couple options. This video is spot on at diagnosing a faulty CCV, thumbs up!

[@BIMMERZEITT]

Thanks for sharing the details!

[@zigo1965]

I replaced it last year, and i think it just blew the diaphragm out of it, the car started smoking pulling out at stops, checked the ccv and it was covered in oil. I'm done with that valve, going with the catch can, why bmw put that stupid valve in that location is beyond me. Did you just block the hose going to the fuel rail? I was thinking of using that one instead of the one on the back of the manifold.

[@CableWrestler]

+D rigo Yeah, I blocked those off. It took a little while to do. I think there's 6x T20 bolts holding it down. A gentle (I mean gentle) bit of persuasion with a crowbar precisely placed underneath it and the manifold, working from the front of the engine to the back. Eventually it'll pop off, make sure the grommets don't come off. There's 2 outlets on the piece we just removed, that can be used, but I think they're fairly different sizes. The reason I opted to go for the manifold and not the fuel rail section is that it's far easier to get to for maintenance, you'll have to block off one of the two outlets and that you would have to use the old connectors, put together some weird bends, and then that's before where you consider the routing of the vac pipe. Don't forget to block off the oil return for the sump either. I can't remember if I said that previously. It can't be accessed easily from above so... The passenger (UK) or driver (US) front wheel removed. Then it can be seen and worked on through the inner wing/undertray. You can just cut the pipe, shove a fat headed and equally suitable girth (giddedy) bolt in the pipe, then put a pipe clamp on it.

[@JMUDoc]

Another way to do this is to put a glove over the end of the intake boot and blow into the brake booster hose with the oil cap both on and off. If the CCV is working, air will come out with the cap off, but not with the cap on; if air does not come out with the cap off, the CCV is blocked.

Tried this on my e46 325i after watching this video and it started dumping white smoke out the exhaust after removing the cap.

[@BIMMERZEITT]

Arnold Rimmer that’s perfect. It should be a very slight amount of suction. As in, you can lift up the oil cap with 2 fingers easily. The intense suction here indicates a ccv failure or clogged dipstick tube.

[@arnolduk123]

@@BIMMERZEITT I see, thanks for confirmation. I've never removed the oil cap on a running engine, but after seeing your video I just had to do it :)

Arnold Rimmer some old school cars you can’t remove it while running or it can spray oil everywhere. The design of this engine allows you to do it though.

[@Tonil875]

So, why the ventilation system doesn't work correctly? I think, this is normal becayse when you take off the oil cap and the idle and rpm of the engine change, and the engine is turning rough, this means that the CCV valve is working correctly. On the other hand, if you take off the cap and don't see rough on iddle as change the rpm, it would be a bad CCV valve. (I mean the opposite of your work. Please explain me minuciously this part of the CCV calve) Regards from Spain!!

[@martymacfly4002]

I think it's the right answer, as long as we remove the engine spinning it must stall!! excuse me from my english I'm french lol

[@cankose4581]

That's what I'm thinking. You are compressing unmeasured air to the engine. That's why engine is stalling.

[@cankose4581]

Technically engine is a closed system right? I'm trying to find an answer cuz I changed my PCV but my engine have strong suction. My old PCV was broken when I remove it and I didn't have any suction before I change it.

[@HowToDoitright]

did you ever get a proper explaination for this? i am in the same Delima...very confusing.

[@Tonil875]

@@HowToDoitright The crankcase ventilation system works under vacuum, which means that when there is an air leak (considering the CCV valve works well), the engine starts to vibrate and the idle is unstable. In contrast, when the system is clogged, the engine loses power and consumes more oil, and idling is also unstable. To check the CCV system, when you quit the oil plug idling, it is normal for the engine to shut off.

[@BIMMERZEITT]

Thanks for the great question. I can't answer it for you though, I don't have any diesel engine experience as they aren't common here in the US. Hopefully another viewer can chime in.

[@albertobellato7009]

On my M57 diesel the vacuum is a lot weaker, as normal for a turbo diesel engine. One can open the cap without particular force or hiss. The most important thing to look for on M57 engines it the health of the PCV filter/separator, located on the top of the head cover: it often gets clogged (because of poor manteinance), increasing the pressure in the crankcase, ultimately leading to turbo failure due to lack of lubrication. On the other hand, if it breaks, rue turbo can start to breathe oil drops, leading to failure. Keep your PCV filters clean and changed, I do mine every 10.000 km. Regarding vortex filters, I received mixed opinions from friends with the same engine, therefore I prefer to stick with the classic cotton filter and increase manteinance. No issues so far (230.000 km).

My car m52 328 1997 lost around 2 liters of oil @3000 miles the car has 104000 miles; ive tested the ccv no suction when opening the oil cap but only idle change and also testing if the car is burning oil ( no symptoms of smoke ) could it be a bad ccv ?

[@smooveking773]

i noticed my oil dip stick is sucking air is that from a bad ccv? or normal

[@Drippppppppp]

Thanks .

[@lalocunha2574]

One question please, in this case would the engine be leaking oil and smoking?

[@Shinko666]

Mine is clogged at the moment I had smoke and pressure coming out of the oil cap and some oil leaked due to the pressure inside the engine

[@lorithomas6914]

Thanks for the info on CCV issues. In the video I saw the coolant tank filler cap on left side when facing the engine and windshield fluid tank in left firewall box. I have only seen that configuration twice and wonder if It is a stock option on 330 CI. I was hoping that I could improve performance on my 330 CI by replacing the air filter box by changing configuration to match what I saw on video. Is the air flow significantly better on your engine than my standard oem 330 CI air flow system. I only want OEM components not after market non stock parts.

[@BIMMERZEITT]

Lori Thomas thanks Lori. This was on my e39 5 series which shares the engine with your E46 3 series. The air box design is different. You will see best performance by keeping the air box stock. Just get a K&N or high flow panel filter is what I recommend. Be well.

[@tiagovids]

Nice video, i have a m52b28 single vanos, i did a leak test on the intake with a smoke machine, and i notice 2 things, with the throttle body fully close there is a little leak in there, is that normal? Also, i saw that the ccv is getting air through the intake to the crank case(didnt see any smoke, but as the smoke machine build pressure i heard air comming through the oil cap), is that normal? Or so i have a problem in the ccv?

[@rolly.999]

Replace the seal on the oil cap

[@marcorivera7154]

my car is trowing alot of white smoke from the exaust. i think it might be the valve but i did the same think and my oil cap is easy to remove and if i open it while on it throws oil

[@bekimretkoceri7636]

Did you fix it yet

[@sammycrack0dirt]

I just changed my ccv, all vac hoses, and intake boots. Now I have a high idle and can't rev past 3,000 and drive over 15mph.. any ideas?

[@BIMMERZEITT]

Did you have a high idle condition before performing the work? If the answer is no, then I would go back and check over your work. Sometimes it is something very simple and obvious that you overlook after a long afternoon of wrenching. Happens to all of us. Just check it tomorrow when you are fresh. Check the connections, sensors plugged in, hose clamps tight, etc. Report back here with what you find...

[@sammycrack0dirt]

BIMMER ZEIT hey man so to answer you question, no it did not have a high idle previously but it did have and low idle. When I turn the car on it idle around 1300 rpms for about 2 mins the come back down to normal and I drive away. If I didn't drive away right after the idle came to normal it would want to stall but doesn't. Did my homework checked around and found : The tube that runs from the bottom of the ccv to the oil dipstick was completely broke in half. And there was also another tube that was cracked badly. I think it was the one that ran thru the manifold. I also changed the upper and lower boots I forgot to mention that. I was really thinking after I replaced and cleaned everything my cars was going to run super nice. It did not! I was really was hoping it was something stupid that I've done. I took it apart and put it back together 5 times now and every time I still get the same results. I do have a video of my issue I'm trying to post later today. I built a smoke tester and I'm going to try that today see what I get. I will be sure to let you know how it all goes, thanks.

[@sammycrack0dirt]

So I did the smoke test and no leaks. Now I'm really stumped

[@djslammedxd6262]

I Got A Bimmer! have you fixed it?

[@BIMMERZEITT]

Is the idle control valve plugged in? You must have a service engine soon light on and some codes stored?

[@cipmars]

A friend of mine has this problem on a 1.8 Z3. We've swapped the PCV to a new one and the problem persists. Any ideas please?

[@BIMMERZEITT]

cipmars check the dipstick tube is it clogged? There is an updated tube on the m54 6 cyl I am not familiar with the 4 cyl engines

[@cipmars]

@@BIMMERZEITT it works just fine with the engine off, the tube is clean. You need to stop the engine to be able to take the oil filler cap off. If we start it with the cap off, it sucks in air.

[@TheJay911]

Should have avoided 4 cyl BMW mate get a proper BMW 😂👍

[@MrFerrill]

Maybe you can help, I got 645 that does the same thing when you remove the oil cap and blowing white smoke, I already replaced both crank ventilation valves and no change, if I let it suck in little air (by no tightening the oil cap) it stops smoking... What else could it be that's keeping the engine all pressurized like that?

[@BIMMERZEITT]

+Alfred Ferrill hi Alfred, I am not familiar with the 645 motor- however- on the M54 the dipstick tubes get clogged due to poor original design and are a part of this whole problem with the crank case valves. An updated dipstick guide tube was added to the parts catalog at some point. Maybe check into the dipstick guide tube for your model, hope it helps.

[@andreyayrapetov]

Your problem is that you have bad valve stem seals.

[@GrzegorzDurda]

There is not "both" ccv's on bmw. The I6 and V8's use a single one. You might have gotten ripped off.

[@MrFerrill]

Grzegorz Durda no sir... pretty sure there was two. replaced both didn't help tho

[@GrzegorzDurda]

I have the 540 with the same V8 and replaced it and i know there is one on the back on the intake and it can be done with intake no removal required.

[@sasiedu562]

Can You do a Video on where the valves are located please

[@adamodri6184]

+CoolinKofi the valve is under the suction pipe, so it not visible. You have to remove many parts to replace it.... big amount of work. (work is more expensive than the ccv valve)

[@laquanmurphy5248]

My 2010 328I BMW is making a loud whistling sound when it get hot after I went and got a oil change

[@paulloper8333]

@@laquanmurphy5248 Mine has the same, see my video, what was the cause? I know this comment is really old, but it's worth a try.

[@StepByStepStudio]

Anyone know roughly how much someone should expect to pay an indie to replace a CCV? The vacuum isn't as bad as this but I do have a slight suction and I do have the yellow gunk ('bmw mayo') around the oil cap. Think it's a combination of thermostat stuck open (never getting up to temp), O2 sensor, really cold weather and possible CCV

[@chrischambers7103]

The Documentary Dude 130 with overnight shipping

[@BIMMERZEITT]

Not sure for an indie but I did ask my service advisor at a local dealership out of curiosity and they charge $1,067 for parts and labor. They remove the intake manifold to do all of it.

[@StepByStepStudio]

Wow, I guess if it's a show car or a newer BMW it would be worth it. These cars (e46) in the UK are about £1000 and go up to about £2000, dirt cheap for a lot of car but the price of parts is horrible.

[@albertdavidian4694]

BIMMER ZEIT I just had it done it came to $1,077 with tax. There must be a universal price book on this service! But the car is running great now. I thought I may have a bad valve. happy camper

Can a failing ccv system cause oil to travel to cylinder(combustion chamber)?

[@tarikosmanovic4723]

Da moze

[@proflytebyron]

Help? I have air pumping out of the hole in the side of the pcv valve on my e36 328 . Sounds like some kind of musical instrument. The cap isn’t hard to remove and there’s no’s smoke out the exhaust. Is the valve shot? Possibly a split pipe? Cars running fine.is it bad to drive it like this? Thanks

[@9N3]

It’s not bad but fuel consumption will be higher may loose power or cause a lean code

[@AllEyezOnMe13]

I have e60 , check for ignition because of the fuel ventilation, help me :)

[@simiongradinaru7381]

That thing look brand new

[@FX-fk8yt]

my engine m54 makes only a little vacum and rpms changes a little in only few seconds. Is it normal ? All ventilation pipes and CCV were cleaned and the valve is in very good condition.

[@BIMMERZEITT]

That sounds normal to me, slight vacuum from the cap is normal. The problem is when the oil cap sucked down hard like a vacuum cleaner and hard to remove.

[@fal121]

2 and a half minute video about something you could explain in a short

[@thooke222]

Okay but this may be a dumb question... If the valve is defective wouldn't there be an increase in pressure inside the crankcase due to the blow-by gases being trapped?

[@KerryxxIanxx]

thooke222 my thoughts exactly if anything it's better that it's sucking air rather than blowing You want the crack case pressure to be removed

[@Z4loorit]

Valve can stick open or closed. So u can have either as a failure. As bimma said better to have it fail open than closed.

[@dantheman1337]

Ccv valve should open and close to keep engine pressure the sane as atmosphere or slightly lower. So under idle the ccv should be shut, not letting air past, and under fast load it should be totally open, allowing lots of blowbu gas to make it to the intake.

[@MrMarx-qg3wu]

I have the same problem. I have been replace ccv and that not solve my problem. Shows bank 1 and 2 all the time and car wont run fine....what the typical issue ? Catalytic conv or 02 sensors

[@BIMMERZEITT]

Bank 1 and 2 what? Lean? You have to be specific. First step should be a proper smoke test of the intake to find leaks. There are numerous areas that can leak including but not limited to: DISA, intake bellow upper, intake bellow lower, hairline cracks in valve cover, valve cover gasket, CCV and its associated connections, oil dipstick tube can be clogged.

[@KamilMrowicki]

So if the valve is functioning correctly should there be any vacuum at all? I had errors for my pre cat lambda sensors and replaced both today with new Bosh but car is still underpowered and theres a minimal suction when removing oil filler cap

[@FStan-co8vv]

Will a bad CCV act the same if your car suffers from a leaking gasket?

[@BIMMERZEITT]

Well, to a certain extent. Leaking VC gasket, cracked VC, clogged dipstick tube on 01 and earlier e39, can all cause lean codes and car to ingest unmetered air.

[@ryedubs1789]

I have bank 1 and bank 2 codes as well. Problem is is I've already replaced the PCV valve and all hoses. What I did do recently was attempt to resolve the P0455 code. I guessed and just changed the purge valve solenoid. One has to remove air box to get to it. It's a pain anyway because of the last hose that connects can be a big problem to remove and put together right. I erased the code and then got these bank codes along with a fuel level low code misfire......where my fuel was running very low. Now, I wonder if these new codes are simply me NOT connecting the valve right? But then I thought why wouldn't the P0455 just pop back up if that were the case? I'm sick of this darn car. I've dumped thousands into it making it run good and efficient and this is never-ending.

[@BIMMERZEITT]

Rye Dubs sorry to hear, they can def be tough to resolve all the way. Some cars have numerous issues or neglect from previous owners, so it takes time to iron it all out. What model and year car do you have and what mileage?

I've done a lot can't list it all but I suspect maybe TPS or MAF and I'm doing tests on that this week. But wondering if this sounds like CCV? THANK YOU FOR ANY HELP
