BMW M47 / M57 Crankcase Breather Replacement

[@mrz007]

I have to say, that my BMW dealer chief mechanic told me that the "old" version, which was not old anymore as it was re-introduced on newer models, the one with the little sponge filter inside instead of the vortex, is more efficient and does a better job than the vortex one IF, and only IF, you are going to change the little filter every 2nd oil change...this is what I am actually doing on my e90 320d M47 163HP

[@carlwood5501]

Correct Mr Z the reason this one is covered in oil is because its not efficient, i have just removed my original one on a 2001 330d 150k and it was almost spotless apart from the filter

[@pedrofalves]

@@carlwood5501 I have a M47 136hp and i rather have the old one than this updated version. Everytime i change it the filter is dirty but the housing is pretty clean. Since its a bit of work to access the air filter and the filter is very cheap i change it everytime i change the air filter. I service the car every 6.5 - 7k miles or every year since i dont do too many miles.

Just replaced the CVV on my own 320d touring, I'm very new to working on cars. And now it no longer smokes on hard acceleration, woo! Cheers for the very clear guide, I wouldn't have attempted this had I not seen this video. Next up, glow plugs.

Did it puff black smoke on hard acceleration?

[@martinbcooper]

​@@shaunhollis1624 It was pretty smokey off the line, especially after idling about for a while. Much better after changing the CCV.I've also cleaned up my intake and replaced the gaskets, made a good difference.

[@ismaelemamally5858]

Does your engine oil level decreases frequently.1litre every week for my bmw x3 2006 2.0 diesel.no oil leak no smoke running well.engine check ok.they r telling me its crankcase.

[@theonlyhowsie4281]

Well done mate! I’m doing mine this week. Fingers crossed for the same outcome 😅 My CVV had smoke coming from it (not a lot!) and oil was leaking out of it a little

[@georgiosz.]

Too many M47 owners complained of too much oil into the intake pipes because of this vortex type air oil seperator.Additionaly,charge air temperature sensor failures may occur because of this big oil concentration on the sensitive electrical component of the sensor with bad affects to injection fuel rate.Too much oil into the intake manifold could also produce soot and DPF cloggage dont you agree?The older loo roll type was more effective in oil gas filtering and prevent oil leakage into the intake pipes...The only disedvantage was the required maintenance every 20000-30000 km (filter replacement).What is your opinion on this?

[@nbrtr4141]

Definitely you're right!

[@georgiosz.]

@@nbrtr4141 Charge air temperature sensor operates badly in my X3 E83 2.0d.Only when engine is on high load on turbo boost shows normal values. On idle or when cruising or deceleration temperature values drop below ambient temperature. I believe is because of oil. If I put sensor somewhere under the hood (I use a 2nd sensor) temperature reacts normally...

[@kent8280]

@@georgiosz. First of all M47 does not have a DPF and second, all the oil who get in the manifold its burned because of the high level air temperature. I removed the manifold because of this thought and it was pretty clean, but I have egr and swirl flaps off and remap.

[@mlgmounted9599]

my vortex breather did send lots of oil to intake, so yeah, you still need to clean that at least,( and i mean cleaning of vortex separator and intake itself) so it is much better to use good "old" fabric filter to prevent that, not to say diesel engine can use oil as a fuel, so it can start revving on its own

Just had my 2007 325D breather replaced after 150K miles (don't think it had ever been serviced) so is now the vortex type. It's like night and day now, had some other major work done and it's like a new car. Love that engine.

I tried to drive with EGR vacuum hose plugged and throttle response was def. better but i plugged it back. I think when car was new and everything was clean, engine was responsive. BMW wouldnt sell it in state in which we have our cars now with everything dirty and on half-way to death :) Thats why i believe egr is not (or wasnt) a problem when engine works as it should. Im also planning to replace MAF. I heard that it was best mod from basically every m57 diesel owner i know. Lot of MAFs are malfunctioning and not throwing code. And also, MAF is controlling EGR as well.

Hi George, great video. I replaced mine ages before my turbo blew. It's been a couple of months since I changed my turbo and I'm having a bit of an issue I hope you can help me with. The engine runs sweet and I'm getting no smoke from the exhaust at all now etc however, when I remove my oil filler cap or dip stick, there is a fair amount of white smoke flying out. I've been scratching my head over it for weeks as I'm sure it's not normal and indicates too much pressure? I'm double check but I don't think there's suction pulling the cap down. Do you have any suggestions? Thanks!

[@anassnouri6129]

I have exact same thing

[@Salamethusayn]

@anassnouri6129 hi mate, don't worry, it's normal. Just make sure your vortex/pcv isn't blocked. I just removed the internal filter altogether. They all have white smoke. That's the smoke that runs from the vortex/pcv valve, along the air box and back into the intake system. I've deleted all this now and chopped the air box off to put an inducting kit on. I made a blank plate to replace the pcv vortex, got a brass elbow on it with a pipe that runs back into the intake, so no need for a vortex filter any more . Cars way faster now 😜

[@Fender7495]

I have the same issue, changed turbo (that blow up) and togheter with the breather... I saw that my engine is "breathing" from the oil cap cus it was dirty with oil, than the same turbo belw up again and smoked white smoke and half a litre of oil (thinking that the engine did breathe throw the turbo, changed again turbo and breather). Checked compression and everithing, it was still breathing through the oil cap. The only thing that helped me was an oil catch can that i connected to the oil hose and the engine is not breathing anymore from the oil cap, but my impression is that she smokes a bit, but oil consumption is not so excessive. Someone can help me? i'm out of ideas, and the oil catch can whitin 1000 km is compleatly empty...
