BMW E46 Oil Catch Can Install DIY
HTML-код
- Опубликовано: 29 сен 2024
- The experiment to determine if a catch can can reduce the oil consumption on the M54 engine is over. My results are:
394 miles: no oil consumption at all
NOTE: I have uninstalled the catch can that I installed in this video. I was getting an occasional problem where I could smell oil fumes and it was honestly very annoying and unpleasant. Please do not purchase the oil catch can I used in this video. Find a better one that doesn't have the oil level indicator on the side and thus will be better sealed to vacuum. Even then, take great care to completely seal up every part of that can.
There is an alternative to running a catch can if you live in a climate where condensation and clogging of the OEM CCV system is not a problem. Please see this video:
• BMW E46/E39 M54 Engine...

Just stumbled across this video and noticed you mentioned me in the comments. You are most welcome and thanks for mentioning me. I love your channel and videos! You are an amazing resource for E46 owners!
Nice done! We installed the System at the secondary Battery Port. But ur way is better cuz it is not so visible.
Also my Port is empty because i use WAES too.
THX for ur great Video!
Hi. I just watched your video on the catch can replacement of the CCV. I see that you have the vacuum source for the PCV valve on the wrong side. The vacuum source goes to the 3/8 side of the valve. Also, the way you ran the drain line from the catch can will eliminate your vacuum source. You'll be pulling vacuum from the oil fill line. You need a check valve in the drain line, but you have to be sure that you have enough vacuum to pull the check ball closed while the engine is running and falls open when it's shut off. You might be better off with an electronic valve that is closed when the motor is running,(power is on) and opens up when you shut the motor off. I think that you will have a vacuum leak and be pulling oil up from the dipstick tube. Remember that you are putting a vacuum on the whole crankcase, which is in the oil pan too. So the check valve you put in the drain line is getting vacuum, and being pulled from both sides!! If the electric valve is too much, you can use a manual "ball valve", which would still make you have to drain the catch can, but it will be much easier to do. Just open the ball valve, let it drain, then close it again. I may be wrong, but I don't think that you will have enough vacuum to pull that check valve closed. It's meant to stop liquids from back flowing, which push it closed. Remember that you don't have a high vacuum to the PCV valve, and you're also using that vacuum to pull from the crankcase. That gives you a vacuum pulling both sides of the check valve. Thanks for the diagnosis of the problem though. I have a 2003 330xi that's burning oil, missing, and a vacuum problem too. I noticed that the vacuum gauge on the dash, (gas mileage gauge) fluctuating, being low, and having to build back up after the throttle is closed at an idle. I was going crazy. I was a mechanic for 40 years, but like a Benz, BMW doesn't give out too much info. I was thinking "vacuum modulator" at first, but it didn't smell like tranny oil. I couldn't find a PCV valve, and then I thought that I had a cracked head or a bad valve guide. I'm not used to going online to find a problem, but it was a great idea, and you are a great help. I felt a lot better when I found out that I was on the right track with my thinking about PCV. (That I couldn't find). It figures that the Germans would make a simple system complicated!!!! LOL. Thanks for a very helpful site.
BMW CCV are used because the intake is lower than the valve cover IMO.
I ran a CCV delete on my 02 X5's without a catch can because I live in the midwest.
There are a few problems with the CCV system, The drain hose to the dipstick gets overlooked during maintenance, carbon deposit begin to restrict the flow of oil to the pan causing backup of oil into the intake (Summer) In the Winter the vehicle needs to reach operating temperature to boil off the moisture aka "Mayo" in the crankcase. People living in colder climates know what I'm talking about. Now with that fluff of "Mayo" and that hose to the dipstick restricted were is the fluff "Mayo" going to go? That's correct into the intake because the old & new CCV drain is plugged.So going back to the first sentence gives you the answer. The valve cover has to be lower the intake so that gravity will drain the oil back into the valve cover. Remove the CCV, Plug up the hose that goes to the dipstick.
Now you will have to connect the intake vacuum line to the valve cover connector. ALL THE CONNECTERS AND THE VALVE COVER CONNECTOR HAVE TO BE ABOVE THE INTAKE. (I'm not shouting just making this very important) Line and hoses to use: Use fuel line which is plastic, the rubber hoses use as little as possible or as a coupling to connect the plastic line to a fitting etc. If you run, to long of a piece of hose they will collapse due to vacuum.
When done no more Mayo or oil consumption ( as long as your rings are still good)
My 2 cents.
When you changed the PCV valve location, I noticed that the valve was facing the same direction only closer to the valve cover. Did I see that correctly? Thank you for all your videos!
What about the moisture build up in the oil pan? I might have missed that. I will watch the video again shortly. Can the crank case be put into vacuum, without the CBC valve, and not coat the intake runners with oil?
hello Jason. my car is 2003 325i and I don't not Have any check engine light is on new while I am driving it look like car acceleration really slow and cusumming a lot of gas can I do pilot mood at and it will fix all the problems
I have recently purchased a 2001 e46 with 140,000 miles and I'm getting the p-0171 & P-0174 lean codes. If my intake boots check out without any leaks I'm gonna assume its my ccv system. At what outside temperature would you not recommend putting the drain line back to the dipstick tube. I live in Tennessee and our winter temps rarely get below 30 degrees F. I just don't want the check valve to gummed up with the mayo like buildup from water/oil emulsion. Thanks
If you're worried about that then just skip the drain line altogether and empty the catch can manually. For lean codes, check out my common vacuum leaks video
Hi 50sKid, really great informative tutorial, thanks for posting. i replaced the OEM CCV like for like several months ago and really wish i watched this video first a) because that vent hose you need to twist int the CCV body stumped me, and b) because i'm getting vacuum related issues now and lean bank codes. i also burn alot of oil so im going to try this mod immediately.
One thing though if you wouldn't mind, im in the UK, and part numbers you have suggested for the PCV are not available across the pond. do you have any kind of info regarding the pressure or flow that the PCV should be please?
Hi hunting, I'm UK also and just doing this mod to my Z4 E85. How did it go for u? I had no problem getting the fram pcv off amazon.
Your car has more silicone than a San Fernando Valley yoga studio.
Thanks for doing the videos, helpful as I work through my M54 oil consumption problem.
did u solve your M54 oil consumption problem ? If so can you share how, i needed to resolve this issue on my M54. thanks
sri nandu same
I did this mod a few years ago. In extreme cold (below 0F), the catch can or pcv would always freeze and blow out the valve cover. Maybe my crankcase generates excessive goo compared to others. I ditched the catch can and vented to atmosphere temporarily, and the pcv would still freeze. Ended up doing the m56 valve cover conversion which has worked out very well. In normal climates the catch can mod probably works perfectly, and I learned a ton from this video.
This channel remains the best resource for e46 owners!
Got a link to the m56 Valley cover conversion cant find one stupidly
For what You install a catch tank when this do not catch? The tank is for the water and oil mixed "soup". Please dont give this bad soup back to the engine. The engine will get a stomach pain from this Soup.
Hey there, hopefully you respond. I did a catch can install on my E46. I used the same PCV valve. How much vacuum do you have at idle? Is it easy or moderately difficult to remove your oil cap? I feel like this setup is giving me a little too much crankcase vacuum. Thank you.
So I used a slightly more expensive can, installed the PVC on the vacuum side and after about 30 miles of non stop driving I can say no oil smell, and it runs great.
awesome vid. definitely doing this. you called the DISA "vanos" lol
I thought I was the only one that caught that LoL
@ 18:31 comment I was looking for.
18:30
reinstall de "vanos" XD maybe u want to say Disa valve,
Hey man 3 yrs later would you still delete the ccv and add a catch can system?
.
, the M52 has an additional vacuum line attached to the Fuel Pressure Regulator. Has any one done a catch can on an m52? If so, how did you tie in the Fuel Pressure Regulator vacuum line
This is old but wondering the same thing for my m52tu 328i
My opinion as I'm currently installing this , replace valve cover seal + grommets first hopefully you already did. Then My best advice to all is remove the entire intake, yes it takes longer but pulling everything off and inspecting all your hoses and parts and seals is key. I was surprised to see what didn't work pulling mine off considering I drove from northstar to Lonestar state no issues.
That's a lot of bits, thanks for listing them all! I'm really surprised that no one sells a ready aftermarket kit for this!
Thanks for your videos, man! I always appreciate them!
(Having two M54s in the yard, I kinda am addicted, or at least depending on them.)
Short annotation @ 16:55: I once broke of the whole port and ended up with a hole in my rocker box cover.
So, folks, be a bit careful with each of those black plastic parts you 'll find in your engine compartment...!
From my own experience, I'd highly recommend to get each of those hoses, quick connectors and o-rings new. Otherwise, you will do all that, ähm, "funny" work twice...

Will this system work on the x5 with the 3.0i
I have a couple of questions:
1) Should the PCV be positioned vertically?
2) my engine has 139,000km's and I don't think my oil rings are worn quite just yet. Will the added vacuum created by the PCV cause excessive wear of my oil control rings if they aren't as worn in?
3) What is the chance that the PCV valve freezes in the winter?
Any updates?…
when I installed my catch can I also started chasing vacuum leaks, I got those same 1/4 block off bolts and got rid of the clear tube. good work on finding those leaks
Thanks!
Damn you put quite some work into this. I'm gonna wait for the results in a month or so before I mod mine. For now I ordered a new CCV to replace the leaking sticky OEM one :) Btw, if anyone decides just to keep the OEM CCV on, check your dipstick drain as mine was so clogged that I had to burn it in order to be able to take all the gunk out and actually have a flow trough it. Nice work ! keep us up with the results.
I might have missed it but what did you do with the vacuum lines that run to the ccv?
Awesome work thanks for being honest cuz most likely i would've made the same mistakes but since u already showed us what not to do i hope we can install the oil catch can 👍
Just wanted to say thanks, your part numbers helped me solve my catch can issues by finding and using the correct pcv! Thanks dude!!
What was your issue to much suction? On the oil cap as mine sounds like a sound can when you open it haha

Yes, I'm a follower, 50kid , great explaining details, including possible common errors , where human :/ I also installed a decent priced aluminum square oil can on my E36 328i and at start up only, it smokes out the tail pipe slighty( 72,000 miles).. My Engine turns over 3 times before starting :( idle is not smooth, up & down 700-1200 RPM radically.. So I watch your video and discovered that not only does the pvc value needs to be facing the right direction, Thanks to you 50kid but mainly I must say that the check valve itself also should be facing vertical in place to work properly , meaning the (ball type) that's inside the check valve should be on top so it's closed even with just a little vacuum on it (idle).. (gravity is keeping it down closed ) however when thottle is increased the slightest vacuum increases enough that the valve opens (ball is pushed up) at that bmw recommended vacuum pressure .. if it's the wrong check valve (light duty ) or its laying horizontal the valve will never be closed( ball type) .. It will stay open at idle and uses engine vapor (incomplete combustion) that causes idle surges when warming up at cold starts only. When icv is fully opened at operating tempertures, restarting with this warm engine now, everything is fine until the next morning start ..other out there when you realize how a check valve works then you'll understand that it must be upright and pressure must open it at the right time .. that's why there's different pressures for different models... FIXED! THE RIGHT CHECK VALVE , ARROW TOWARDS VACUUM , VERTICAL INSTALLED.. Thanks 50 kid for leading me on..hope this helps others.. PEACE
Thank you ! Thi is absolutely damn correct !
@50sKid I just compact catch can for my BMW however it doesn't have a drain at the bottom should I drill it out to put the pilot mod on or just try without it? Please get back to me thank you also love watching your videos you're my go-to guy.
Kenny Springer most budget catch cans just have a canister that unscrews like an oil filter. Most of the budget one are too thin to drill and tap for a drain fitting.
can i use a one way check valve instead of PCV? (im not running mine back to oilpan)
Ive ran a pcv valve inside the same tube just be sure to check the valve especially if engine has milky foam from water in oil will clog pcv valve.
hey @50sKid
so I did basically the same install, used a different catch can also didn't do the oil drain like you did, my catch can doesn't have the little drain like yours but the rest I did pretty well similar
my question to you is about the pcv valve, I used the Napa one you provided at the bottom, I'm curious is that one of the part numbers you updated? my concern is I get a considerable amount of vacuum in the crank case, I figure that's something I should expect. but I get a bit of suction pulling the dipstick or oil cap while running, I'm concerned there would be residual side effects from that, besides the debatable benefit of the vacuum on the cyl rings.
any feedback will be much appreciated
That amount of vacuum is normal, that's the whole reason doing a mod like this improves your oil consumption. The side effects are if there are ANY vacuum leaks in your valve cover before you do the mod, they will be amplified by the increased vacuum now placed inside the crankcase. I recommend changing your valve cover gasket and grommets to a fresh one.
I have gone through 5 vacuum caps on my dipstick tube since installing my catch can exactly as you did. Please tell me what is wrong because I can not figure it out
Also, I purchased a $200 mishimoto catch can to install initially
Ok, need some help, did a whole top end gasket replacement on my 325xi, and I'm stuck and getting the dipstick in. Lol, of all things. It seems to be 1/2" off the bolt hole. Does it really bolt in to the engine mount??? Also my car is on 4 jackstands. Any ideas? Do I need to jack the back engine/tranny up?????
For me you is a wonderful bimmer,other person was desmount all air intakes for this operation,nice explained and nice videos,for me is bit dificult for language,but dont worry,I practice hehe,thank you very much,and testing Obd later and change o-rings thats good idea companion,nice your job,perfect job

I don’t think it’s a good idea to recirculate the catch can into the oil pan via dipstick tube.
Excellent content on your channel, great work! Interesting you say, you smell oil vapers and your catch can is not vented. I've been running a vented catch can on my G35 for like 10 years now, no pcv valve at all. When I modified the lower plenum and saw all of the oil residue in the intake system, I was like how is oil in here? Then I discovered the vented catch can, which stopped this and oil consumption. The gf's e46 has been consuming more oil than normal and this is what brought me to your channel. BMW definitely made this way more difficult than it should be, but I"m impressed they made something to address it vs just recycling blow by oil through the motor. Not sure how the diaphragm in the CCV helps stop the blow by oil, but interesting. I was told that the diaphragm can get stuck open and that is a reason for more consumption, but I was also told an engine code will come up when it does. No engine code. This upload really gave me some insight to the install.
Any reason for not doing a vented catch can? Once vented, you don't need vacuum to pull open the pcv valve and can just drill it out. Can't I just vent the the valve covers and plug manifold to ensure no oil vapers are being recycled back through the motor? Thanks for this upload and I've always thought the e46 is a legendary design.
You can, but you'll smell oil in the car due to the way the fresh air intake is designed as well as the amount of blowby these engines have at this point in their lives. You're not really recycling that much oil into the intake at the end of the day--I know the inside looks oily after a while but it's not like you are burning oil or dirtying the back of the intake valves or anything. People get too paranoid about an oily residue on their intakes.
Thanks for the response, but as I dive further into your video's I'm making you repeat yourself, sorry about that. After watching Cyclone Crankcase Ventilation System Explained, you know what is up.
I believe by that installation you've made more pressure in the crankcase (blocking the hose from the deep stick). I have an idea which I've already done on my car just need to make milage to check if I'm right. I've just cut the hose coming from the separator to the intake, and I leave it to breathe in the air, then I block the intake, so no more vacuum in the ccv, just running as the older cars.
the catch can i got wont fit a 1/4 male mip adapter to barb... literaly must be like a 7/16 female instead of 1/4 it looks liek it fits perfect just doesnt thread
Amazing video, how is the setup holding so far? Im about to do this myself...
This entire excursion is just not worth it for me .....thanks for your experiments.
Got my bmw back on the road today after studying this over and over the finally got all the lil parts thank you boss man
Great video @50sKid, the best one I've seen on this mod. Good camera and sound production, thanks!
Question: Will this make it so I don't pass a smog test in New Yorkistan where they use computer devices? (BTW, it's probably not a bad idea to replace the lower dipstick O-ring with a new one, as long as you're in there, no?)
Just FYI, (Being an ex-certified gas and marine pipefitter)Teflon does hold up to fuels, but it's much better to use a high quality (not cheap hardware store junk) non-hardening pipe thread sealant on both the threaded connections and the gaskets. (I used Permatex White Teflon pipe dope). Believe me, it's well worth it. Tape for amateurs, lol
So, keep up with the great videos Kid!!!
Probably don’t want that vapor draining back down into the pan. It’s not just oil being ventilated.
I have an important question... So, I keep coming back to this video. Thank you for explaining everything in depth. However, the PCV location and direction you kinda rushed through at the end, and I couldn't exactly understand. I bought the purolator 1050 PCV, same like yours. I'm also going to drain the oil back to the oil pan with a check valve. BUT, Where do I put the PCV. Between valve cover and catch can, OR between catch can and intake manifold? You mention something about your mistake causing the PCV to stay closed. And then you show edited footage of you putting it back where it looks like you're switching around which hose you said to go into. THANK YOU VERY MUCH =)
Pcv between catch can outlet and inlet manifold. Pcv threads towards inlet manifold. Imagine the flow of air out of valve cover through catch can and into inlet manifold. Blow on the pcv valve, it'll only flow 1 way. Then fit it the way the air is flowing so it doesn't cause a blockage.
Fuck that is very Nice! Goooood Jooob man. Salute from Germany 💪
Kid . Finally a video on a catch can !!!! I have been running this setup for about 5 months . Good idea to change the can it gets filthy on the inside . And yes teflon melts with oil it makes a mess inside de can . Great video my friend
Cheers from Mexico !!!
I ended up removing the ccv system and routing a line from the valve cover port down to the ground to avoid smelling the vapors. I Sealed off the two small ports on top of the intake and put a cap on the oil return line port @ the dip stick.
6 months and probably 5 thousand miles later it seems to be runing ok. I'm no enginer- I dont know how much vacuum goes through the system but I need to know what and how much damage it might cause. # 02 E53 X5 @240k
Purpose of CCV (PCV) system is reduce air pollution (1950), and became a law in 1961 (California) that every car require it to reduce pollution.
BMW (and many other) engineers designed the vacuum system by considering the pressure of CCV to archive the optimal performance/operation.
In practical for car's life that is 20 year, removed the CCV and drain directly to atmosphere does not make significant damage to the car. However, the contamination is damaging entire human population for easily next 100 year, not to mention food contamination (due to soil + air + water + river + ocean = vegetable + meat + fish + drinking water + animals)
Did anyone have a oil catch can on their m54 during a California smog test? Did it pass and did the see the the oil catch can?
Hi 50’s kid m ur big fan plss reply me this -i hve installed catch can on my e46 330i yesterday same as u did but i did not use pcv valve and now i hve soo much vacuum dat i hardly can take the cap off and it throw the engine light on i did read the codes about 5 of them all abt lambda sensor bank 1 bank 2 soo my question is -is it all coz i did not use pcv valve Thanks
Fixed needed pcv valve 👍🏻
you shouldn't step down the pipe sizes to fit the catch can, you should get a catch can with ports the same size as the breather ports because it can restrict the ventilation.
also i wouldnt want to run my disgusting catch can blow by oil back into my engine. if you really cant be fucked draining a catch can just vent to atmosphere.
Yes Yes Yes ! Comment of the year ! Only somebody foolish would not keep the OE diameters.
Am doing this to my 2.5 Z4 but I want to install it and keep my PCV system “oil separator” thing. “Getting a new one” trying to figure out how to have both....
Jose Perez that’s pointless though...
Stock PCV works fine if maintained properly
What should we do if we have the m52tu and there’s a vaccum line going from the oil separator to the fuel pressure regulator (if I’m correct) what should we do with that vaccum line
run a longer vacuum line to the back of the intake manifold, there are capped off vacuum fittings which you can use
I've been running with the PCV valve mentioned in the video. It's great, at idle engine speeds but starts to work improperly at highway cruise speeds, resulting in higher fuel trims and spikes in fuel trims. The solution to this is to probably get an adjustable PCV valve like the Wagner DV-17. You can't use it in below freezing temps though.
Addendum to this. Do not use the Fram345 pcv valve or the DF17 Wagner. Neither solve the fuel trims. PCV valves are flow type valves. These do not allow for proper crankcase vacuum of 16mbar. Use the oem ccv vacuum regulator portion inline with catch can to maintain right fuel trims and bypass the cyclone separator.
The problem is that you can't use the vacuum from the rail it must be from the rear intake port or it will be too much and suck oil through the catch can, also the pcv is not needed, if installed sideways the valve will not operate right, that is what your $15 catch can install didn't work.
That's what the PCV valve is for dude, to reduce the air flow through as well as to provide a check valve against pressure going the other way (in case of backfires). It's just a little round ball or plug on the inside with a tiny opening to reduce the flow through it. Who told you they need to be installed upright? I've only ever seen them installed sideways in cars. Doesn't matter which way they go. And it did work, it just sucked and smelled like oil like you were talking about in your video.
The e39 smells because of the terrible unsealable cabin air filter boxes, the e46 does not do that, that clear tube got pulled down from hitting your wire loom and made it leak, you have to make sure it is straight and locked in, I'm not trying to be a Nancy but look at all the cars that go through my channel and never a lean code after the can is installed, also you have to use fuel line or it will collapse on itself under vacuum, and that will push the seals out on the engine , we both can agree that the original CCV does not work, which is more than most BMW shops will admit, they don't want to give up those $600 CCTV replacement jobs I guess lol
I did make sure the clear tube was locked in. I showed proof on video that it DOES leak and showed why. Those things are not air tight, man. Not only do the little teeth leak in between them, the blue "quick-disconnect-like" thing does not seal around itself because it's plastic and not rubber coated. I'm not the only one to discover positive fuel trims after installing one of these. Like I said when I was commenting on your video, it's not enough positive fuel trim to throw a code, it's about half way there. But trust me half way there is enough to cause poorer gas mileage. If those lines were going to collapse they would have done so during idling which is when vacuum is highest. I'm also not the only one to have the problem of oil smell after installing these either. Gotta use a better can, there's no doubt in my mind. I suspect with all the RTV and the o-rings and what not I had some small leak somewhere when the can got hot. I'm not knocking you for what you choose to use or install, btw, I hope you don't take offense. I'm just sharing my experience with this.
Btw I'm gonna have to disagree that the original CCV does not work--it actually works just fine and only needs to be replaced maybe once in a car's life except under extreme conditions like very very cold winters. I recall hearing about one guy who replaces them every year because he's in the Colorado mountains or something, but that's a unusual climate. Just because something that is made out of rubber needed to be replaced after 100k miles doesn't necessarily mean I'm ready to re-engineer it, ya know? Bushings, o-rings, gaskets, it all goes to crap after that long. We'd be replacing everything that is rubber on these cars. My big goal for this was to get the increased vacuum to solve the oil consumption issue for now. After I'm done with my rebuild I'll switch back to the stock CCV. I'm good with the check valve providing me protection in case the diaphragm ever fails and causes too high of a vacuum/suction.
But... I've got the M5 oil separator from the E39 sitting on my bench and I will do an install of that along with testing if it produces fumes, which I know it won't but I'd like to be sure. I honestly think it's gonna be the best way to go because it's got a built in drain valve fitting and is all plastic which will provide more insulation than a metal can.
You do have a point about the 3/8" line that I chose to use. I remember it getting my hand dirty when I pulled it off. Definitely should have used fuel line (I was only planning to keep the install for a week, that's why I used it). Perhaps those lines were oozing oil through them and when everything got hot under the hood, it was baking and causing the smell. I mean, it's possible. Because I did have that catch can sealed up vacuum tight...
You can also get those separators on the x5 with the m62tu, the 540i and 740i use the kind behind the timing chain, but remember those drain to a banjo fitting line at the top of the oil pan and it does not actually sit in the oil on the m62tu , i think it will pull oil through but i will let you experiment and see what you find out, remember the v8 cars still have the ccv diaphragm on the rear of the intake so the vacuum is very little going to the separator
Can we just fix it the right way in stead doing all this
Thanks for all your knowledge on these vehicles and your how to videos
Hi. Wondered if you can help me. I love ur videos. I installed a catch can. Blocked off oil dipstick. Used the pcv valve you suggested. But im getting a massive vaccume which is stucking oil cap down a lot and maybe causing oil to be sucked up from the sump. Any ideas? Would really appreciate any help you can give. Thanks
How is the oil consumption now after 3 months?
Vielen Dank und liebe Grüße aus Deutschland.
Hi
There’s something wrong with my ccv valve. Is installing an oil catch can gonna “fix” the problem? Thanks
Yeah but it'll end up creating more problems. Do yourself a favor and take the day to fix it properly. There are many things that can reasonably be bypassed, but this is not one of them.
@@Wmoore1 thanks
These quick connect fittings are terrible choice for vacuum applications, they are only sealing with positive pressure, explains why you had such a bad luck with it!
Hey man. Great video. Looking forward to see your long-term test results. This solution could well be my saviour!
I've seen M54B30 race cars use an E39 M5 oil separator, part number 11151406788. I will attempt this if/ when my ccv fails! Thanks.
Niaaal wow, I didn't even know such a thing existed! I wonder what it looks like on the inside...
And here we go, this is what it looks like inside: i1095.photobucket.com/albums/i467/mach-schnell/M5OS.jpg It's basically the exact same thing as the catch can I installed, only plastic and a different shape. But at least you don't have to plug anything up or worry about vacuum leaks. Just super simple, connect 3 hoses and be done with it. I like it.
Have a look to the reference 11151705237 (oil separator for X5). I have found it on eBay even cheaper. Not bad at all! Thank you for your very interesting videos! (E46 small 4 cylinder N46B20 owner)

@@50sKid hi, i know its an old topic but hey we stil have our cars hey haha, anyway trying to clarify which is the best method closest to stock CCV, if am correct the CCV somehow filters the moist in the oil or something like that? On the oil Catch can you installed does it not just sent back the oil direct or does it have a filter in it or is there a better alternative, seen on the link the plastic one with a filter. Is that better or its the same? Please advise.
I realize it's a 6-year old video, but I'm setting up a Catch Can in a 2004 e83 M54 2.5l and I want to know how to select the correct PCV for my application? How did you select the Napa 2-9358 for your application? I really prefer not to attach a hose to a threaded end; Really prefer to have a PCV that will seal to a hose.... I'd appreciate your thoughts/comments.
1 quart of oil every 1000 miles? Wtf. My 2001 330ci burns nothing. Maybe you got a shity car? Did you use the vacuum from the intake rail? That's way to much. Use the lower vacuumed plug from the back of the intake.
Hello engine m52tu mileage 400000km oil consumption is not !! but the original valve is very problematic! This air suction oil in the collector and its replacement !!! made oil catch with fuel filter valve FV345! Vacuum is strong, I understand that it is good, but only for those who have oil levels, I don’t have such problems because m52 and m54 motors are different !!! the difference in the piston group because m54 eats oil like a bull)))) author many thanks !!!!! Only there is a question I can not understand how the valve FV345 should work !! I have it blown in 2 directions ?? I need help!!!!
help help help
today I was out for a test drive and much oil comes out of the exhaust ... I installed a PCV ( PTC 345 ) but i was wondered these is a metall and its clicking when the PCV Valve is chacked, should the is a sping inside?
I open my catch and see there is no vaccum the direction of the PCV is correct
Also I wonder the catch on my last 30 KM around 20 Miles testdrive have catched much water // I must say I drive the car most time in short distance
next step the check the valve or installation without a pcv valve // or close the intake ports and output from catch to the air filter
It’s actually routed the wrong way, my valve cover now has a crack in it & is now leaking onto my exhaust.
There’s 2 lines. U literally can’t mess this up
After installing my catch can, I did not experience any oil smell in the cabin. I notice you did not install hose clamps at each juncture. Could that be the issue?
If it's not baffled what's keeping all the vapor and other crap from going right back into the dipstick tube? I'm curious cuz I need to replace my ccv system and just wanna eliminate it all together with a catch can.
Nothing is keeping the crap from going right back into the oil pan. If you don't like that arrangement, do not use the detain line. Just use the stopper bolt and drain it out on the regular
Hey, what might happen if i dont use those valves ? Only straight hose ?
Great work ! Very nice videos, thanks for all of them ! :)
Any small vacuum leak becomes a much bigger vacuum leak because you're putting full vacuum on the system.
He ment the pvc valve and non return valve on your return pipe
The catch can is completely pointless using your method!! Why return the manky crap back to your sump? This is blow by gasses and burnt oil, why would you want it back in your sump??
Hey there, going to use this on my Supercharged M54B30 instead of the way Active Autowerkz system now vents CCV back in to the charged pipe... Hate it! If you are going to dump oil back in to the pan through dipstick just 86' the sight tube on the can and block off. Thanks for your vids.
Hi 50skid!
Im Laszlo from Hungary!
I would like to ask a little help if you can please!!!
I saw your M54 engine Oil Catch Can video. I really would like to do it on my E39 but I have a M52B20 engine.
Any differences in install or same ?
Please help me if you can! :)
Thank you very much!!
I installed it works fine. Drive about 40 km 25 miles, and check the tank or container that comes in the decanter and it is almost full. For what is this?
hi 50skid!! I have got m52tu engine . my ccv have fpr vacuum hose if I delete my ccv then where I can put it in my fpr vacuum hose plz tell me I have done m54 oil cathch can but m52tu engine it have problem the fpr vacuum hose so what am I have to do!!
Thanks your video.
I have some questions
My E39 is M54 525i engine
Are there any disadvantage to delete original ccv systems after long time test?
For example: oil consumption or air leak problem
Will OBD detect error code after delete ccv systems?
Thank you for the Video. I did the same installation on my car and when I drive for a test it drive really smooth but start smoking from the tilt pipe so I pull over and check the oil dipstick and nothing on it so I towed back yo my house and find out spark plugs are wet of oil do you thing I installed it wrong. Catch can has an input and output which one goes where? Thank you!
50sKid hi, I'm struggling to find a good PCV valve here in UK that could suit for the catch can system on my 330i, I bought one for a JEEP CJ 3.8 and 4.2lt, but seems to be quite small. I still didn't start the mod, so I'm still on time to buy another PCV that will be the right one. Meanwhile, thank you for all the videos you do, I've learned a lot about my 330i thanks to you, and saved lots of money doing the jobs myself!
I've got a question about the catch can installation. Can it somehow be connected with the check engine ligth on after you install it, particularly depending on the diameter of the tubes used? I did mine and I used the N54 original catch can that perfectly corresponds to the 19 mm tubes in and out - this fits to oem connectors and FRAM FV 345 PCV. After installation everything runs perfect, but the check engine light appeared. Can we assume that this diameter gives more O2 after MAF and causes CEL? What's your opinion?
50sKid. The AddW1 catch can does not have that rubber line,.Its a little more money, but is is all metal.I am running it on my 04 e46 320i for about 3mths now,no problems. P.S i bought it for $90.00
Not going to work. The check valve to the dipstick is spring loaded , the can wont drain. If you take it out it will suck from the pan
50s kid is one of the few people who understands that PCV valve is still needed if you use oil catch can. Basically you rebuild the original M52 PCV system with aftermarket components. Without PCV valve the high vacuum (when car is idling) will suck a lot of oil fumes from the crank case. This is the purpose of PCV it should be only open when throttle body is open.
I have stock CCV with the O2 pilot mod. I don't live in a cold climate. However, once my stock CCV eventually fails, do you think a catch can is an upgrade? Or should I just replace with new stock CCV to avoid vacuum leaks and whatnot? My fuel trims are under 5% at idle and it'd be nice to keep it that way.
Oil catch can is a nasty name for a part I would want to install on my M54 BMW. I would suggest looking at the German Auto Solutions upgrade. It looks very professional, opposite to an eBay product.
Great hard work though!
Would someone care to explain me why this is an improvement? What is wrong with the original system?
I have an E39 525d 2001, no oil consumption. Why does this install prevent oil consumption for petrol BMW?
Anyone know the thread on that PCV valve? As a builder of PC cooling systems, the idea wading it up and jamming it in there instead of getting proper fittings, makes my OCD tweak. Oddly the dude in me sees no problem with this ;).
I got the fram fv345 ,how do I assemble it ...it comes in 4x parts. Thank you
Basically that is a Pneumatic connector and due to it connects pneumatic tubes (so air flows inside), means they should not leak. I don't understand why yours had problem.
Hello what is the easiest way to find out if you have a bad oil separator i have a 2004 545i that's smoking. Pcvs are good too out 4 spark plugs no oil plug is dry ?
Do your self the favor and get the cheaper catch can. I’m having the same vacuum issues on the mishimoto universal catch can. Also please make sure you get the proper o rings for the dipstick and clean the mating surfaces of the dipstick. Story of vacuum leaks with my 330. Disa valve vacuum chamber failure. Catch can flaws. Improper dipstick o ring. Day three and finally getting a grip on it.
HI 50's Kid, just asking hows the vehicle oil consumption rates at about 1000 miles and engine oil smell or smoke inside the vehicle as what you mentioned in the video. I'd like to know what is your final assessment on the oil catch can project and it's latest part update. I have an X5 with M54 engine and interested with your modification, as usual and normal oil consumption issue.
Did this, everything went well, 8 months later, massive oil leak from the valve cover, and later learned there is a pcv valve built into the m54 valve cover and it was whining. I’m going to take the intake manifold back off to install the oe Ccv system, anyone have any suggestions on what I should do differently? Like a specific pcv valve? I have no kinked lines and I’m running a return line going into the dip stick on my setup.
Hi there, looking at catch can on E85 Z4. Do u think I would need a pcv valve if I used the smaller vacuum inlet located on the bulk head end of the inlet manifold? M54 engine.
Thanks in advance....... Tim.
I installed a catch can the same way you had done in the video using the fram Pcv valve. Now I have pressure coming from my oil dipstick. If I remove the dipstick on my catch can (causing a small vacuum leak) I have no pressure coming out from my oil dipstick.
Please advise what is happening and how I can fix this.
Any leads on after installing this, having misfire and SES light but no limp mode EML light, you can just feel it misfiring at certain throttle positions.
Funny on such a modern car that you have to add something old hot rodders used to do in the 60s. That was way to complicated and time consuming. But you have a great knowledge on the bits of your car.
