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.

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!

Thank you so much for this video! You are addressing all the points that seemed strange / wrong to me.

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.

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.

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.

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.

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

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.

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?

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.

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.

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.

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)

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.

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!!!

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.

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?

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

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

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.

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 !

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.

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 ...

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.

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.

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.

When I block the tube with my hand, the engine runs well. Do you know how to solve this problem?" Thanks Josep

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?

@OLearysBMW

2 жыл бұрын

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 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?

@OLearysBMW

2 жыл бұрын

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.

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?

@OLearysBMW

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!

Hey, so how can I reduce oil comsumption without overhauling?

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.

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

@OLearysBMW

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

Thanks for this great video. I'm running a M52b25 with M50 inlet. The PCV is removed and the hole in the maniefold is plugged off. I'm running a AN10 line from the valvecover to a catchcan with an airfilter on top. No vacuum. The car is only used for trackdays, and has no numberplates. When I drive the car with full throttle down the straight and let off the throttle in to the corner, there is comming alot of blue smoke from the exhaust. Is the because of the missing vacumm or is the pistonrings ready for a replacement ?

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.

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.

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.

Will this cause misfire in 3 4 cilinder if cloged

Hey! Do the three vacuum endings on the intake, on its right side(cabin side), should be closed?

Hey there, depends what model your car is. 323/328 cars use the bigger port for EVAP. One small one for SAP solenoid, and last one capped Typical 325/330 have the bigger port capped, and use both small ones for SAP solenoid and vacuum canister for muffler flap.

Outstanding! Where is a good source for OEM CCV system?
