- This is a HUGE topic for me, I honestly don't know why I take it so seriously. Haha, it's a great system. I explain my thoughts, share my experience and describe bad methods all within this video. This video, is a must watch in regards to the CCV system as a whole. Stop deleting it with terrible setups.

Thanks for putting it all in perspective. Concise considering all the details. Your delivery bleeds of experience. Thanks from the community!
Nicely done. You presented your argument well. I think one big takeaway from this video is that these CCV systems last 100,000 miles. Who can complain about replacing a wear item that lasts that long.
Mine didn't last 100k miles. The aftermarket CCV aren't as good as the OEM CCV I suppose.
good video, well spoken...I can agree that 02Pilod Mod works, at least works for me. I have 330 and I had oil consumption about 1L on 1000km after I refreshed whole CCV with every single hose and O-Ring as preventive maintenance with Genuine BMW parts...after 02mod, consumption almost completely gone, and I am not a grandpa driving.
Your video just popped up as I was watching videos on catch can installs. I had just watched the 50s Kid on his installation. And then yours shows up! Perfect timing! After watching yours I am going to go with OEM CCV system as you suggested. Thanks for your insight.
Not a problem at all! I appreciate you for watching. 😁
Awesome education mate, thanks heaps! I now understand much more about the CCV system than ever before , and I agree, the catch can system is a bad idea!
That tiny hole on the back of the intake is wild!
There is a reason the turbo boys on the forums talk about adding more vents to the valve cover to very nice catch cans
Where on the back? LOL more holes for more hp? lmao
1998 BMW 528i M52 "330,000" and still going strong. I agree 100% I learned the hard way with my 2005 Audi TT. Unless you have a custom built race car with a custom tune, don't delete and just run with the OEM systems
I'm so glad I found this and the follow up video.
I have a 2000 E39 528i wagon M54 Auto. 144xxx miles
Diagnosing a oil leak and overheating amongst other minor issues. First time bmw owner and first time tearing a motor down. Used to the older 90s Ford😅🤣. Inline 6 for the win!
Bought it off a good friend around the First Stimmy check. He had bought it from a shop and had it for a month and it blew a upper radiator line. Parked it, later on gave me a good deal and I fix the line, got it running and drove home. Have Had it for a embarrassing long time and it had overheating issues . Didnt drive it much cuz of the issues. So We towed it at our family mechanics but before he could get to it he had medical issues come up first. Got the car back and decided to try to fix it myself with my father.
We've Torn the motor down to the cylinder head (intake off, exhaust system dropped, front bumper removed, cylinder head removed) and I'm getting ready to start the rebuild.
Going to redo to entire cooling system along with deleting both fan clutch and Aux fan to a single electric dual speed fan mounted on the radiator. Cooling lines, water pump, thermostat and since I'm already down to the head I'm going to replace the headgasket too. I think I got a fix for the fans but havnt yet tackled that issue.
More importantly. The CCV system on the intake I found when removing it. The oil return hose to the dipstick was blown. So I did my research and found Nathan'sbmwgarage and 50s Kid videos very helpful on the whole teardown process but I was thinking about going to a oil catch can on a stock NA system but seeing these videos I believe I'm just going to replace the CCV with a new one and continue on the rebuild. Too much hassle with a oil catch can unless I go full send and turn this wagon into a racecar.
Once I get the whole car running again I may looking into a transmission swap to a manual but I've heard those are a pain with German vs GM spec transmissions so maybe..maybe not. A topic to discuss after the cars fixed🤣.
Great information. Great explanation. Loved every minute of it. Thank for taking time to make this. Very helpful for first time bmw owners and people who are going thru the trouble of fixing these cars.
Welcome aboard! Loved reading your detailed story. Fun stuff! Inline 6 is definitely the way to go, always ❤
I wish you luck with your rebuild/project, 😁
Thank you for the information!
I currently work on a M52TU coming from a M50. All this is new to me.
Thank you for being so comprehensive. I will not run the delete. Just replace what's necessary
I’m going to replace my CCV on a ZHP and well done on the explanation. You should always remember engineers spend years figuring this out.
Thanks for the great explanation and discussion. I daily drive my 2003 325i (currently 240K miles), and am encountering the oil consumption issues like many others.
I've bought the ACDelco Upper Engine Cleaner. I plan to try the heat-soak in the Spring of 2023. I also appreciated the explanation of the O2Pilot Mod. All of this has helped me (a non pro, who likes DIY repair & maintenance) to understand what's going on.
With your skills of presentation and explanation, I'd love to see a video of the heat soak process.
Thank You for your kind words, I appreciate that.
Hoping one of those methods help you out. 👍
Best explanation I’ve seen. Really appreciate how you lay out the whole system and failing of these alternate concepts. Btw - fluid flow resistance is proportional to 1 over the radius of the pipe to the fourth power. This is why just a small build up in the intake manifold port can have such a large impact on performances.
😮so glad I learned this before swapping it out for a catch can and down sizing the hoses like Nathan said. But he knows this by now. Doesn't want to be wrong so he won't say anything probably
God bless you. The only one telling the WHOLE story. I would like to see your ideas on the PCV valve cover design, I have had endless problems with the diaphragm and excessive vacuum in the engines(on 07 328i,330xi,X3 3.0L)valve cover gaskets and eccentric sensor seal.
Dan
Man I’m a LS1 guy. Bought a E46 for my daughters first car. And I’m learning what to replace before I toss her the keys
Glad I could lend some useful knowledge 👍
Thank you so much dude, I was debating on doing a catch can because I’ve seen a bunch of people doing on the 330i, but after this it makes sense why the ccv is very stout and holds up. Definitely going to go oem again due to it being a daily and I’m not tracking it
Not a problem, glad I could help!
Thank you so much for this video! You are addressing all the points that seemed strange / wrong to me.
I couldn't find a single negative comment on this video and that's because you did an excellent job with it. I'm convinced you know exactly what you're talking about and I've decided against the catch can method. It must be nice being really smart?
Good and relevant info for our newly bought M54 project! Another good case of It's There For a Reason. Many thanks for the advice.
Great video. Really appreciate the info on the upper engine cleaner. I just picked up another m54b30 and its showing low compression on 2 cylinders dry, but good compression across all 6 with oil squirted in. Might give the upper engine clear a try. By the way, I picked up a bunch of 330 body parts from you back in the fall. Those are already coming in handy for some of the Spec E46 guys. Keep me in mind if you're ever parting out another! thanks man.
One of the best explanations ive seen thanks for sharing your knowledge
Not a problem, Thank You for your kind words.
The ccv and intake should both be replaced at the same time.
It's about 2/2 the price to replace both with Amazon items vs the catch can set-up.
Maybe if you were going turbo a catch can would be necessary. 👍
Great video
Thank you for helping to stop damage to individuals vehicles.
Once I seen the vacuum pressure on the crank case in those other videos... Lol 😮
That's me educated! I'll stick with OE set-up and a smoke test on those hoses. Great, as always!
Thanks for all of the info and experience. Love (and hate) my 2004 330i ZHP.
Epically clean e46 engine space , looks like new :D
Congrats!
I started with total reparation also. Almost entire bottom setup is new
I'm new to troubleshooting BMW vehicle, so your information is helpful
Thank you, it opened my scull up with that information
So... correct me if I;m wrong , the best way to delete a CCV is to just vent the valve cover with a hose downwards into the open ... loosing some oil but best and simplest if you don't care the potential smell
I had my ccv swapped out and my car started drinking oil more. It has 224k on it , M54 motor.. My car only has smoking issues when I leave from a light ( not all the time ) , off the throttle and getting back on the gas..
50's kid mentioned that people have installed new ccv's and had issues with more consumption , more than likely due to the piston ring moving out of its groove etc..
I have a feeling it's my valve guides. It's about a quart every 500 miles.
My e46 has 140k miles and still original CCV with yellow sauce inside. I am ready to replace new CCV but one hose has yellow sauce in the tube to the oil pan bottom. I need to take that out and also replace oil pan gasket.
Ok , I’m huge Bmw & e46 m54/m52tu fan . I believe this is the best explanation I’ve ever seen an heard. I personally just replaced mine with aftermarket an personally I ordered oem an replaced again . With time I learned only oem made in Germany parts work on these cars . Thanks for the information
You're welcome, Thank You for the kind words.
@@OLearysBMW no problem you deserve it for sharing this information. I do have a quick question. When you showed the vacuum ports on back of I take . Do all 3 of those have a hole for vaccum? I noticed only the 1st one you pointed to and shined the light in on mine has a rubber cap . The other 2 are open
@@chadriddle3517 yes, that's totally normal. There is a cap there on 325/330 models.
You have so much experience with these motors. Awesome discussion
Still learning new things about these cars to this day as well, haha. Thank You for your kind words. You may Subscribe if you'd like, I appreciate it greatly in exchange for my time 😁
I remember that comment. Might switch back to CCV after watching this. Lmaooo, cheers from e46 owners group! (Richard Sagra)
🤣 I was looking for it again. LOL.
Cheers! 🍻
😂🤣🤣🍻
Hey Tyler, could you explain what CCV setup you’re running?
@@bobafittness1346 custom oil separator system inspired by the P54B20 engine.
pls drop more knowledge, as much as i know everything around my e46 id like to learn "secrets"
Brilliant, very informative video. Thank you, Tyler. 🏁
Thank You for the kind words, you're welcome of course!
My original CCV was still working after 130k but replaced it anyway. They usually go wrong when they get gunked up from driving short journeys and not letting engine fully warm up.
Yep! As stated, The Ultimate Driving Machine. You have to drive these babies, not put put around town.
And number 3 people also move that catch can away from the engine it's close to the engine on purpose that way it can heat up the oil and separate the oil from vapor
True. Overall, they knew what they were doing when designing the system. Just very inconvenient with M54 series getting those crappy piston rings.
I forgot to add, the method I described in the video of soaking the cylinders is also used for recall services at dealerships, for the older Scion TC and other cars. Because they have severe oil consumption from the same thing, piston ring tolerance. Sometimes it works, other times not. Haha
Glad to see someone appreciate the design of a component. BMW will spend more today on R&D than any of us will earn in a lifetime (or two). There’s a reason that everything that’s on the car is there. And you need a very good reason to think that someone else has come up with something better. Especially a used coke can and a couple of straws. The muppet comment is classic UK… and another one for WAT for you - Thumping the nuts off it
Amazing video and very thorough. Have you ever replaced the piston rings on one of these? (Are they serviceable for an engine builder?) I love working on the M54 family and I’m planning a B30 swap for my 325i for fun.
This month I’m doing my 100-150k+ maintenance on two E46s I have and the cold weather CCV is on the list for both. It’s actually the main thing. I love the placement of it, it’s out of the way during other minor maintenance items and when you take it off to do the long term maintenance, you then get to change everything else like the hard coolant lines and misc gaskets. I honestly think a lot of people that take these off are scared of normal maintenance or don’t do it themselves, so they feel that labor burn at the dealer.
People that “delete” the OEM stuff for “ease of use” really don’t think it through in my opinion. You can’t usually out engineer a German. 😂
The piston rings of M54 can be swapped out for that of an M52TU. At that point it'd be a full on rebuild/refresh of engine.
And yes, an unbaffled sub $50 catch can believed to be better than an OE CCV is laughable. There are decent kits available from Radium, as these are proper cans with suitable hosing. Much preferred.
All in all, OEM CCV does as it should for 100k+ miles.
Out engineer a Team of German Techs is Almost impossible! OEM All the Way!
Smart people listen to other smart people. Great Advice Here!
Hi I found your channel and I want to say that you to a Great job of explaining what you are doing and why! Love learning new perspectives on things I already know something about!! Haha like this video! I have to say I agree with you on this ...but .. in learning a lot from Nathan also, I put a oil catch can on 3 of my M54 engine x5's first about 5 years ago and still running fine. I am not sure it is running primo but still going. Basically my thoughts are like this ... not everyone knows everything and not everything needs to be perfect because these are not aircraft carrying people they are just (old) cars!! But love it! You do an awsome job here! Thanks!! Have a Happy Day!!((
Have you looked at the G.A.S. CCV? Probably the best solution by far, but pricey.
Great video! Now you just need to review the GAS solution.
Thank you for your response and assistance. Misfires. I think it’s the CCV is burnt and I’ll swap it to make sure it is. I will look that up. When you say to smoke tested, do you have any videos on how to do that test?
Yeah I'm just in the process right now I'm replacing CCV on E39 528 I destroyed my e34 by fitting catch can it just wauld not run correct so I put I back to stock but it still never did run right I ended up selling it catch can is a no go zone on bmw
Good video, well explained and laid out, nice job. One thing you never told us is, "why do people feel tempted to do the catch can set ups? " is it because they feel it makes the car faster somehow? what's the appeal to even do it in the first place?
Hey there again, man. So people will resort to installing a catch can in replacement of the OE CCV typically due to laziness, they see an easy method done online and figure that's the best route. There are other reasons as well, example being with the M54 engines having the weaker oil control rings, can potentially slow or stop excessive oil consumption. (When done properly)
Thanks for the very thorough explanation, loved it.
I recently had a b30 engine swapped into my car and the guy that did it put a oil catch can setup in it, it’s a Amazon baffled catch can I don’t know if it’s setup wrong but it smells bad when I drive the car like gas and oil I can’t take it, I know he used a pcv valve and the hoses look ok, I ordered a oem ccv kit hoping that will take care of the problem, appreciate your input on this subject 👍🏼
I enjoyed this I’m trying to get my e46 running again
Glad i found your video, im curious if having an open filter on top of the catch can would reduce the high vacuum that you say a catch can would produce. Ive owner my e46 since 13 and was on the verge of installing a CC due to the high milage and not caring so much about doing things by the book
Exactly what Im telling people for years, but nobody listens when there are so many tuning companies advertising their next catch can over and over again. Just take a look at professional products, like the Mann & Hummel Provents to get a perspective how big these systems need to be.
Two questions I have about the video:
1- All the catch cans you mentioned both didn't have baffles to catch vapors & had undersized ports. If these weren't the case, would they function as intended?
2-You mention venting to atmosphere for track cars only. If you're building a wheel to wheel race car would you vent to atmosphere and delete the factory CCV?
Hey there! Baffling of course helps the purpose of the catch can, the main objective here is regulating proper vacuum and crankcase pressure.
Loads of Spec E46 racecars use the OEM system, as well as an endurance/road racecar team that I partner up with.
Hope this helps!
This is exactly what I was thinking. The engineers designed the drivetrain the way they did and these hack mods can cause various damage. The people doing these mods are not mentally on the level to be modifying these systems. Further, they are deleting parts like throttle regulators, etc... Which is way beyond their mental authority. Also, the mods are a liability dealing with California smog tests, mechanic shops and trying to sell the vehicle and preserve the value of the car.
Excellent video, Tyler, thank you.
Just wondering about the three vacuum ports at 9:20 - should they not be plugged in normal operation? Otherwise aren’t they a constant vacuum leak?
The bigger one is plugged naturally on 325/330 M54 cars, but used on 323/320/328 M52TU for EVAP. The smaller ports are used for SAP solenoid and muffler flap vacuum canister if equipped.
Please help changed starter but have a vacuum line that’s a little bigger and do not know where it goes I can send pictures
What about converting to an m56 valve cover? Im putting together a 328 for my 325 wagon and using an m56 valve cover with a serviceable valve.
Very well said!!! Thank you for all of this!
I’m so glad I stumbled upon this video ty you my good man
You're welcome, I appreciate you for watching. Wishing best of luck upon all of your projects, 😁
great job explaining
Very informative video. I am looking into doing a M50 manifold swap on my M54B30 engine. Would I have to re-install my CCV system so I don't run into those issues?
Good stuff. Any thoughts about bypassing the original failed ccv to a new ccv but relocated to a more accessible place in the engine bay?
Thanks for the video you really helped me understand exactly what this system does… im currently sorting out my 330ci msport and want to replace everything on the ccv, if original bmw isn’t an option due to the cost in aus is there a aftermarket brand that stands out for quality? Febi, rein, meyle etc etc ?
You're welcome, 👍 Rein is okay, not sure if Febi makes a kit or not for CCV.
Awesome discussion!, thanks a million bro.
Hello! Great informative video! I have the m54b25 and have just completed the m50 manifold swap. How should I go about ccv/catch can? Car is tracked with occasional driving! I planned to run a catch can ran to valve cover, and intake manifold. But thinking filtered catch can ran to valve cover only may be best? Hoping to hear back from you!
Not sure if you’ll see my comment but about a year and a half two years ago I had a lot of issues with my car E 53 b30 n54 I fixed all of them and ended up doing the AC Delco cleaner on all of the cylinders and the car ran amazing after haven’t had issues besides little things. Fast forward to now I’m getting weird rough idol sometimes when it’s cold and other things and a lot of oil consumption as of recently, I went through and checked a lot of my vacuum lines and seems good. Do you think I should do the AC Delco cleaner again? And CCV was replaced about the same time. I did the cleaner also no check engine lights.
Excellent explanation. I'm glad I always stick to stock! Do you have any recommendations on how to take care of a code P1092? Thanks in advance!!!
Great video.What if I adapt this BMW sistem on a VW TDI ENGINE?
Hey im building a drift car so i don't want plastic stuff. Im venting to atmosphere and im consuming 1l per 1000km or so. Keep in mind i sit on limiter alot.
M54b30 car.
I want to have a catchcan and some crankcase vaccum. Stock stuff is 3/4" lines. My catchcan is 1/2" so i think it will be ok for flow. Just trying to figure out where to hook it up. I guess i need a big inline pcv or just go straight to the intake manifold? Local bmw guru said intake between tb and maf. So then i don't need a pcv and i just get slight vaccum at wot which is when i care about it.
Hi , Can you help me please? "I replaced the valve cover gasket and after starting the engine, it started to hum and the engine ran as if a cylinder was misfiring. The humming noise comes from the CCV tube that goes into the valve cover. When I disconnect it, there is pressure coming from the tube that causes the humming. When I block the tube with my hand, the engine runs well. Do you know how to solve this problem?" Thanks Josep
Very good explanation 👏🏼!
I recently got a conversion done from European n42b20 engine to m52tub28.
The guy who done the conversion has applied the o2 pilot mode and the vaccum is crazy ,it’s difficult to remove oil cap when the engine is running.
I knew that this wasn’t necessary mod as it’s the m52tu.
Now I’m questioning if this excessive vaccum can do any harm to the engine ?
Before I had a standard CCV set up on my old engine and installed a catch can to the valve cover out put and the the return to the original CCV pipe that was originally connected to valve cover.
Is it worth doing this again while I have the o2 pilot mod ? Or should I just leave it as it is ?
Thanks !
Excessive vacuum only from the O2 pilot mod tends to be harmless. You can simply remove/cap the vacuum line that completes the mod if you'd like. You should see the vacuum created from the other setup I talked about, it's immense. Lol
Great Video! You saved me much time & money.
Very knowledgeable A+
Thank You for watching, 😁
Hello! I have a m54b25 with m50 manifold swap. I’m wondering if routing the catch can to valve cover, and then to the large ICV port? Since I deleted the icv could I use this and save my rear main seal?
Very informative! I came across your video while researching my sudden increase in oil usage on my 1999 BMW E36 M3 convertible. I also own a 1999 E36 323i convertible.
I’m thinking the CCV valve is bad on the M3. I guess my first question would be is the system on the E36’s the same as the E46’s? The M3 has the S52 engine and the 323i has the M52.
If they are the same, do you have a video showing how to remove and replace the CCV valve and hoses on the E36?
Thanks so much for the great video…I was about to do one of the suggestions of Nathan’s on the M3. I hope he’s not incorrect when it comes to adjusting the bands in my 323i auto transmission because I just followed his procedure when I changed my trans fluid and filter!
Hello, the E36 system is different from E46, but still operates somewhat the same.
I've always been wary of the catch can setup, which is why I still have my ccv that was replaced years ago. My problem now, is I'm getting started with an m50 manifold swap, and everyone just switches to a catch can for simplicity. Any thoughts on how to retain the ccv with an m50 manifold, or is it possible to plumb a baffled catch can to work well?
This was a discussion in one of the FB groups, people have retained the OE CCV with M50 manifold, they got tired of fiddling with different PCV valves, haha. I'm not exactly sure of routing, but it's been done numerous times with the original CCV
Yeah, I lost track of that thread and couldn't find it again, lol. I'm sure I'll figure something out once I have all the parts.
I could never understand putting less size pipe on it. Its supposed to have the correct size.
great explaination, can't thank you enough
You're extra welcome. Thank You for the support, love my viewers 😁
Hi! I have this oil consumption issue on my M52TU that maybe you might be able to help, since it seems you have this whole CCV system perfectly under your grips :)
So, I bought my car with a CCV that was making duck noises 🤣. It was not consuming any oil at that point. Decided to replace it: bought the OE CCV, but bought the hoses from Febi (keep this in mind). Even though the system was working fine, the pipes were in horrible condition. The one that goes down to the dipstick tube literally just crumbled when I barely touched it.
After changing the system, the car started drinking 1 quart every 6-700 miles! Fiddled a bit with the hoses and it was not burning oil again. Forward a bit and I decided to change the engine mounts, for which the oil dipstick tube had to be untied -> the car started drinking oil again. At that point I was baffled. Bought a new dipstick tube gasket, replaced that, no change. It now drinks oil at an alarming rate.
What I think: those damn Febi hoses are not up to spec and they are preventing the system from operating normally, especially since this is a very sensitive system. I plan on buying them OE and see if that changes anything. What do you think? Is it possible or is just money thrown down the drain?
Thank you for the great video!
That's an odd one. So the car is for sure only burning at this rate and not leaking it?
It does leak a bit through the oil pan gasket, but it can’t be leaking all that. It would have a huge pool of oil under at the current rate. The small quantity that it leaks is captured by the plastic tray underneath and is not pooling there either. The exhaust tips are pitch black and, of course, they weren’t like that before, they were actually spotless, like new. Thanks for the reply, much appreciated.
@@mariuszanfir2298 okay, defintely sounds like a buggy CCV. Hm, interesting. Perhaps a bad one out of the box. How much vacuum is present at your oil fill location with engine idling?
Well, the CCV did work well for a while, but maybe it is indeed defective. However, considering how it did not work well and then worked well after fiddling with the pipes, I’m inclined to believe the pipes are s**t :). Will check the vacuum, though last time I checked there was some.
Checked the vacuum and it does have some. Now, I do not know how strong it should be. It's there, but is not very strong. It just slightly pulls in a napkin.
Hi man!
Can you answer me to a question?
Why my N52 engine runs rough with the stock ccv (a new one) and when I install catch can betwen valve cover and CCV it is running smooth like a new baby :)).When I m running without catch can the pressure on the oil cap is higher, it is open harder then with catch can.
I m trying to figure what is the best mode for my engine.I run a day with catch can, it get some moisture, smelling like gasoline, and after I read somewhere about the pressure on the VCG I removed it imediately.Now I m searching for a solution, I know that my engine doesnt require a catch can so hard but I don;t want any moisture on my disa anymore ...
THX!
Hello, thanks for the vídeo, my m54b30 e60 is driving me crazy and now is undriveable, on cold start has an rough up and down idle and it stalls, lot's of white smoke like vapor, lot's of fuel in the mix and smell, little's pops on the coils, isolated spark plugs with fuel, lambdas accusing bad mix, and all almost disappear after the 70+ temperature system mark, a lot of sensors and mechanics revised and changed for nothing, now I'm focusing in the ccv my last hope and thinking it might be it 200k km and never changed, your vídeo is the most logical one. Do you think this is related to my problems? My car consumes oil at an alarming rate 1l in 3k to 5k km before this problem the rotation in idle sometimes goes up 500rpm to 800rpm briefly and and without warning wouldn't start at first try like it was flooded... I've tested and changed injectors and the rail completely, maf, checked disa, idle valve, lambdas, thermostat, electric cables and terminals, dme, you name it.... I'm losing my mind
Great explanation and answers a lot of questions I’ve had!! I do have to ask though, how do you feel about the m56 valve cover to stock Ccv option? Or even m56 valve cover with an o2 pilot mod,
The M56 valve cover is good for heat resistance. I like seeing them used in vent to atmosphere setups.
I've had 3 M56 cars in my shop, every one I've seen, the intake manifold is very dirty and oil contaminated, compared to traditional CCV system.
It's ultimately up to you, it's a popular modification.
Hey, I found your channel because I bought an e39 with 3.0 have you ever had an issue when you get in it, it cuts out completely?
Thoughts on vacuum from exhaust going to radium catch can
Keep up the good work!!!
im swapping my valve cover out soon with the m56 with the ccv already built in i just have to figure out where that port is going to go and how to block the old system off
M56 valve cover is 'okay'. I like seeing that cover used for vent to atmosphere setups on track and turbo cars. After having three M56 cars at the shop, I find the intake manifold to be much more dirty versus standard CCV system when using the M56 cover as it's intended.
Hi... first of all. I 'm not good at English.
Great video what i wanted!!!!!!!
I deleted CCV and installed oil separator (genuine parts for korea vehicle).. any way
I installed the gas hose to the back of manifold which you mentioned on video.
You mean.. the vacuum hole of the back of manifold is terrible? Not recommend??
If then... it will be more better if i use big hole of air DISTRIBUTER?
*Of course i understand you recommend Original CCV system.
For the time being. I can not do replacement
Original CCV.
*My vehicle is BMW E39 (M54 engine)
Hello. Yes, back of manifold is bad. Using big hole for distribution rail is better, but still problems because you need need proper PCV vacuum pressure.
Using hole at back of intake will be okay for a short while only. Do not use it long term or you will ruin gaskets and seals.

Thank for your advises.
Yesterday i changed hose line from back to front big hole (distribution piece). Sooner or later. I wll add one more return hose for another small hole (distribution piece).....
I have been using the hole of back of manifold almost 1 year. But did not drive
hard. Almost city (traffic jam)
Anyway I have to test more. I really really
Understand your comments for Original CCV and pressure.
Thanks again!!!!!!!!!😀😀😀😀😀

Today... i added one more small hole of distribution. Of course. I'm using Seperator with Diaphragm (Not just catch can)
Anyway thanks for your VIDEO!!!!!
Hey - question- when u soak the pistons with that liquid- u mention - next morning crank the pistons to get it out - can u explain on that please ?
Yes, you don't want excessive cleaning solution in the cylinders.. Leave spark plugs out and crank engine to blow out cleaner.
i have a 2009 128i.. im getting the occasional blast of blue smoke amd rough idle... im thing pvc/ccv... how do i know if its the one under my intake manifold or the one in my valve cover ? i seem to have 2 ?
15:29 mine isn’t capped off it has a small hose coming out of it I have a 04-1 / 330ci
Probably has O2 pilot mod then. No 325/330 use that port from factory.
Any equivalent product to that ACDelco stuff? Having a heck of a time finding it.
great job my friend many thanks ❤❤❤
Great vid. How much, if any, vacuum is acceptable in valve cover? With car running when I open my oil filler cap I have vacuum and when removed the engine runs rough. I've been told when this happens it means the CCV is bad (or hoses....etc) Is this true or should I always have vacuum in the valve cover?
There should be some vacuum at the valve cover, yes. The car will idle a tad rough when removing oil cap while running, as you're creating a vacuum leak. Normal CCV operation is a light/moderate sucking, not excessive. Either way, car won't enjoy removal of oil cap while running.
Outstanding! Where is a good source for OEM CCV system?
FCP Euro, definitely. Lifetime warranty on all products. Even oil changes, Awesome company.
Hey, so how can I reduce oil comsumption without overhauling?
So, for a track purpouse car (best configuration for perfomance) yo recommend venting to the atmosphere directly from the crankcase? passing through a cheap catch can or mantaining the ccv and venting to the air instead of the intake? Thanks!
I have a friend/customer who road races their 330ci. 8 hour track sessions, they use the original CCV without hitch.
But yep, vent to atmosphere will also be okay.
@@OLearysBMW Many thanks for the answer! I'm from Spain so my technical english is not perfect, ..what do you mean to use original CCV without hitch? Do you mean without connect it to the Intake and venting to the atmoshere from the CCV?
And when you say vent to the atmosphere will also be okay you mean using catchcan or venting directly from the crankcase?
Apart from my english I'm also a noob with this kind of cars, I get my 330i just some months ago, I want to use it in trackdays mainly.
@@rafaelricogarcia9550 "without hitch" means without any problems. The original CCV works fine in his track car. No modifications.
-Vent to atmosphere, allowing the valve cover to breathe on it's own, with or without catch can/ with breather filter.
@@OLearysBMW Thanks! What is the valve cover? So, will you recomend to mantainnde CCV and then instead of connecting it to the intake put a breather filter after the CCV?
hey there,
im driving a supercharged 325i (Infinitas/G-Power) with water/meth injection, runs very fine. CCV is about 2 years old, OEM.
I have a massive oilconsumption, about 1 liter per 500-700km atm. Got worse after installing the Supercharger. I read a lot about thos Oil Catch Can stuff or the O2-Pilotmod, cause i thaught that might help a bit. But as you mentioned in your Vid, i am not a big fan of those "mods". O2PM might be worth the try, but read bad things about this either. Also the CCV-Piping is now a bit different due to the Supercharger setup.
As im planning to do a renewed b30 swap, i dont want to change to M52 Piston Rings, but do you have any recommendation what might help to reduce the consumption? Oil is getting more and more expensive though ^^ Currently running a 5W-50
What is your opinion on better "catch can" set ups that function as Air Oil Separator - Return (AOS-R) systems such as Radium and IAG. They run heater hoses through the system to facilitate evaporation of air/water/fuel and filtering systems (IAG even has a spiral) to ensure only oil returns to your engine. I guess technically the CCV system is an AOS-R of sorts. However, I have read quite a bit that runs contrary to the longevity and durability of the stock CCV system. Wondering if you think they would be better overall than stock CCV if done properly (ie crank case pressure, oil consumption and durability)...
Oh yes, I absolutely stand by tried and tested products. That would be a separate video, this one aims more towards the typical daily driven E46.
There are a couple decent kits on the market, Radium.. etc. I personally don't have hands on experience with such kits, as to why I don't commonly talk about them. As who am I to advertise something I haven't tried myself.
Very useful video! Do you think I can leave the crank case breather out and daily drive it? Got a m54b30
Hello, yes. If you plug off the vacuum ports and leave the valve cover vented to atmosphere. My personal car is currently like this until I get a replacement CCV. Be warned, with your heater-AC on, oil/blowby vapor can make it's way into the cabin with the engine vented to atmosphere. You'll smell it. Not entirely healthy to be breathing for a long duration.
When putting a turbo or supercharger on the M54, what do you think about running 2 original CCV valves then instead of a catch can?
With turbo, it simply will not work. It's a headache. Throughout the groups I'm apart of, there have been years of testing on both street and circuit cars. They either vent to atmosphere or use venturi exhaust scavenging evacuation methods. With supercharger, it has been shown that some sealed setups work with them.
Great explanation of the CCV system, best I have seen so far. I wonder what you think about a catch can setup which works inline with CCV. I have a catch can lying around and want to install it while keeping the CCV, my goal is collecting all the liquid instead of burning or recirculating or returning to crankcase (oil, gas vapor, water wapor etc) I replaced my CCV with a Febi one and I think it works well since my oil consumption is almost zero (except sustained spirited drives for days) but oily film in manifold and throttle always disgusts me. Living in a relatively hot and humid climate. Didn’t see any mayo anywhere yet. What are your thoughts?
These engines being port injected, keeps the intake valves very clean. Even in high mileage, so the burning of said vapors doesn't really harm anything.
Any extra moisture that does make it's way down the dipstick tube will be burnt off with normal operation.
I myself have ran a catch can with an OE CCV, I found it to only gather condensation/mayo within the lines. As the OE setup uses relatively short hoses, which in return doesn't give the crankcase vapors time to cool and gather.
Hope this helps, 👍
@@OLearysBMW thank you for your promptly answer. So with an engine which doesn’t consume significant oil (rings replaced 30.000 km ago), working CCV, does it mean I shouldn’t consider catch can? Oil cap feels like doesn’t vacuums enough to me, not much resistance on idle. That was why I considered the can in first place. Short trims are around 7-9 and couldn’t find a vacuum leak (at least not an easy one).
I have to admit I got a little bit distracted around the end of the video and couldn’t apprehend your setup :)
Thanks again mate for great video and answering the comments!
@ absolutely, you're welcome! I will reply answering your other question when I'm home, about to lose phone service as I'm heading out to enjoy some fishing 👌😁
Help me, i have replaced my ccv and now the ecu say me an error on gaz pedal captor and butterfly, i said butterfly because in french is papillon
Make sure throttle body plug is properly fastened.
