BMW E46 Oil Catch Can Install DIY

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!

[@adamtomcheck4328]

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!

[@noneya96]

Got a link to the m56 Valley cover conversion cant find one stupidly

[@LG396]

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!

[@ducewill]

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 !!!

[@rustyastra]

Just wanted to say thanks, your part numbers helped me solve my catch can issues by finding and using the correct pcv! Thanks dude!!

[@noneya96]

What was your issue to much suction? On the oil cap as mine sounds like a sound can when you open it haha

[@noneya96]

[@redhouse409]

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

[@TheMetaliXPlays]

Hey man. Great video. Looking forward to see your long-term test results. This solution could well be my saviour!

[@parsedout2576]

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.

[@srinandu4597]

did u solve your M54 oil consumption problem ? If so can you share how, i needed to resolve this issue on my M54. thanks

[@EnzoSw20]

sri nandu same

[@MARVELB3ATZ]

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 👍

[@chadfoust6942]

First class DIY! I love how you edited it. Subscribed.

[@themechanic6117]

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

[@50sKid]

Thanks!

[@zackaryzamiar1926]

Hay man. Thanks, I copied your build on my 2000 e39 and it saved a lot of time. I love your content.

Wow. Like we talked under CCV video! :D Thank You very much for this movie! On next season i'm doing it in my M52TUB28 ;)

[@Chungi2020]

Thanks for all your knowledge on these vehicles and your how to videos

[@molliarti]

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

[@bdjohn1]

Done. Thank you. I ran my lines over to the empty space on the passenger side and mounted the catch can there.

[@GigiBeleaDK]

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.

[@christophedawson7481]

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

[@solutionseeker5680]

Thank you ! Thi is absolutely damn correct !

[@mercilessBLOOD]

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!

[@jukezauxe]

you’re the best dude !!! you got solution for it all shout out to you

[@TedSchoenling]

very interesting. I'm going to combined this with Nathan's DIY video and see if I can take the best of both.

[@tazak786]

one of the video I've seen in a long time. thank you for this video

[@Alteisen_]

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... kr from Munich! Markus

[@emalvic]

Will this system work on the x5 with the 3.0i

[@vidgarage7577]

I installed my ecs tuning catch can on 330ci e46 2 days ago, runs perfect no leaks, i used the napa pcv valve and completely deleted the stock ccv. I installed the can in the open battery space in the top left very impressed!

[@50sKid]

Nice, let us know if you get any oil smell as time goes on.

[@vidgarage7577]

nothing so far the fitting are great with o rings and the can screws on together very nicely o ring as well, everything seals nicely.

[@TheBSHE]

Since it has been one year. did it fix the oil consumption?

[@LoonAtNoon]

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.

[@RashadSultanov]

Thank you!!!!!!!! Will wait for description

[@DavidRamirez-ck2ph]

I been doing your hose method and it runs awesome. I been using air water separator. Next step is to use the same pvc as for the return oil line. Oil will only return when the car is off.

[@vahramshahmiryan2214]

Thank you for the video bro,alredy ordered the Can.

[@SirFrancoQ]

Great job bro, really enjoyed this Vid& thanks for trouble shooting the system so thoroughly too. I am considering installing the kit, will have to source a good catch can here in OZ! Fortunately we do have the “Smog” test here in OZ👍😄🇦🇺🇺🇸🚗

[@dkay129]

I used a 3/8in vacuum cap to cap off the dip stick CCV line but after 3 months the cap split open and started gushing oil everywhere! I didn't see that leak spot only until after replacing the oil filter housing gasket (thanks for another great vid). Now I'm using a 1/2in vacuum cap with a hose clamp to keep things sealed off. The 3/8in vacuum cap was stretched too far for this tube size so I had to avoid using that same size again.

[@50sKid]

wow, good to know

[@THEDRUMMERJOSH]

This should be sold as a complete kit. I like the feed back into the dipstick

[@skinprison]

So awesome! Your videos are the best they have saved me so much time and money. They're clear, detailed and well made all of them. I think you had the PCV valve right the first time though I put it on the intake side threads going towards the manifold. Thanks and please keep it going!

[@50sKid]

Thanks dude. It's not a matter of where the PCV valve was installed, it's which way it was installed. I wasn't able to flip it around and put it in the same spot the 2nd time because it had a 1/2" end and a 3/8" end, so I had to put it in the other hose.

[@khaledkisswani3904]

YEP YOU ARE great just one note this problem happens when you decelerating for a long time going down a slope when you push the accelerator you'll note the smoke

[@dawiskid187]

love the set up clean work thks for the upload..

[@vasilbachev6592]

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.

[@BlackDahliaFan]

awesome vid. definitely doing this. you called the DISA "vanos" lol

[@patrickpoeling]

I thought I was the only one that caught that LoL

[@rasonjason4066]

@ 18:31 comment I was looking for.

[@burntnougat5341]

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.

[@burntnougat5341]

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.

[@yoshi1u2]

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.

[@tylermorrison5858]

cap the side oil level clear tube. you don't need it and is a source of oil smell. keep making these videos we love it!

[@50sKid]

I did it cap it and it still smells like oil.

[@solutionseeker5680]

@@50sKid Hey, do you happen to remember the hose size for the dipstick tube ? Is it really a 3/8 as you mentioned it ? Seems smaller, like a 5/16? .. Could you remember, please, please ? Thank you !

[@billfly2186]

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.

[@raddegickel3927]

Das hast du sehr schön gemacht. Nice

[@tommyzed1]

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.

[@benjaminbonsall3715]

Ingenious. Thanks buddy!

[@brucevictor5433]

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!

[@brennenblancarte8280]

Love your videos bro thank u a million do helpful

[@Cywilian]

Hi, great content, very helpful. Just one question on catch can, I assume there will be water vapour gathering in the can, so depending on climate you my be getting fair bit of water in your oil?

[@MotordyneG35]

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.

[@50sKid]

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.

[@MotordyneG35]

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.

[@legocommanderstar]

I might have missed it but what did you do with the vacuum lines that run to the ccv?

[@ShakotanRon]

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?

[@AlphaFlight]

Niche video! Like these install ones

[@carlnoki]

found your other video on the scanning tools. got it. :-)

[@davidblair2007]

I have watched almost all of your videos and I absolutely use them as a Manuel lol this one however confuses me in the beginning it seems you have the pcv valve in the tube from the valve cover then at the end you say it's in the one from the intake runner please specify witch tube it goes in I am going to install this system today and am confused also I bought all the parts in your description and the catch can is different have you done a vacuum test on this can you recommended a quick reply would be great and again thank you so much for the videos I absolutely love them

[@larryklassen6770]

NO MORE WHITE FOAM IN MY OIL Love your videos. I've had my 2004 e46 330i for 13 years now and love working on it. I'm currently doing the notorious plastic heater hoses and getting the starter rebuilt for the first. When I first got the car I noticed white foam under the oil fill cap which concerned me and designed my own catch can which I quickly realized won't work in the part of Canada I live in with super high humidity in the summer and -30 in the winter. The reason a catch-can won't work here is mainly the freezing in the winter so I had to come up with another solution and quickly as the heavy foam was totally plugging my ccv system. I replaced my CCV system as I thought it wasn't working but it was. The BMW CCV is very good but can't handle the super cold and high humidity of where I live combined with short trips. My solution is very simple, 100% effective and free and you keep your BMW CCV system. All I do when I come home is lift the hood and remove the oil fill cap and watch the steam bellow out as the engine cools down. Summer or -30 winter is no different. It's amazing how much steam comes out and in the last 10 years I've never had a speck of white foam anywhere in my engine. The thing that bogs the factory system down is when you turn off your engine at freezing temperatures all that water in the engine and CCV system freezes. By eliminating all the moisture every time you turn your engine off helps the factory system manage the larger percent of the moisture while the engine is running. Hope someone finds this helpful

[@domenico1388]

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!

[@sergeypasutin6940]

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?

[@OLearysBMW]

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.

[@busterscrugs]

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.

[@judgegarry]

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!!!

[@arnie3a]

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.

[@busybob25]

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

[@kennyspringer7668]

@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.

[@TheMysticSpade]

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.

[@mike.135i]

can i use a one way check valve instead of PCV? (im not running mine back to oilpan)

[@shopscott1735]

hey man awesome videos great job is there any plugs to the stock ccv that will throw a code after deleting system ? or does computer just forget about it ? per say

[@redbach23tube]

great video. this is so much easier on a VW GTi.

[@e46.r]

Greetings.Great video! I just wonder, I have seen a few setups without PCV valve. What is the worse that can happen if we do the same setup without the PCV valve?

[@jaydenwiggins1995]

We’ll with this, the oil catch cam going to the dipstick tub would gather water and dump it right back into your engine, which is very bad, you would need to add a water separator, if you do the second method by blocking off the tub on the dip stick you could get Hugh crank case pressure and blow some engine seals

[@Z4loorit]

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.

[@bouba958]

hello, you put a PCV valve between the rocker cover to the inlet of the oil vapour recovery and a second valve between the outlet of the catch can and the inlet ?

[@DGrant1801]

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

[@50sKid]

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.

[@DavidN5X]

Prompt please buttered close to the probe have the valve closes to dull or not explained to how to do?

[@APP150]

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?

[@jd7896]

Does this also function to provide increased crank case vacuum (like the O2Pilot mod)?

[@scottcrawford3328]

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.

[@PETEFLICK]

Thanks again for this great vid! But what is a cold climate? I live in The Netherlands and it can be cold... Like to hear your opinion on this. Keep up the great work for posting these great vid's!

[@jimbeam9977]

I heard you say your located in California, what area if you don't mind me asking, I'd love to have you take a look at my E46

[@victoranguiano7401]

What do you do with the hose that you cut do you plug it or do you take the whole thing out and then plug it? confused about that part

[@TedSchoenling]

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.

[@mariodelcampo8164]

What would happen If I connect the hose from the oil catch can to the vacuum port on the back of the intake manifold instead of to the intake equalizer distribution? I'm talking about keeping the equalizer and not capping it off. Is it possible to let the intake of the equalizer free absorbing athmospheric air? Or maybe it would work to run a hose with a tee from the catch can as well to keep this part absorbing vapors? Great channel Jason. I'm impressed with the amount of knowledge you share and the way you do it.

Essentially nothing. It's just another source of vacuum and I doubt it would change anything on the catch can side of things.

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, I think the turbo charged engine , they suck this along with the external air.and push into the manifold. in that case , does the vaccum leak is a trouble ?

[@mcycleserv]

another great video..question on M52tu the vacuum line from fuel regulator connects to the CCV ..so if you replace the ccv with oil catch tank what happens to the fuel reg vacuum line ... this vacuum line does not have much vacuum and is for leaking regulator diaphragm isn't it ..maybe connect to oil drain before the one way valve with 3/8 to 1/8 garden Tpiece. am going to do one of these PCV units but will use the 16 mm inlet and outlet on the catch can so only have one odd size ...great work again

[@50sKid]

The fuel pressure regulator doesn't need vacuum in order to function, that line is just to route fumes/gas in case the diaphragm ever bursts. You can leave that line disconnected.

Thanks for the vids your awesome 😎👍

Hi again 50s kid, ive been trying to find you catch can install video where you found that you put the PCV valve in the wrong way, so it was being sucked close constantly. I have bought the correct PCV valce for my 318 and im not to sure which was the flow goes as there are no flow marks on the valve. Do the threads do towards the valve cover and the non threaded end towards the catch can? thanks Mark

[@mfadzlijamaluddin]

Hey Mark. If the pcv doesn't has any flow arrow, just try to mouth blow to each sides. If you could blow it through, that means the side you're blowing is the upstream.

Nice informative video

[@bwalyabwalya2796]

What's the advantage of deleting the CCV as opposed to replacing it with a new CCV?

Vielen Dank und liebe Grüße aus Deutschland.

[@ricardotorreblanca1269]

Soo the hole of the oil separator will be left open? I feel I missed if you capped it off or something also about to top hose is it just left connected?

[@DriftSpec.]

where do you hook up the oil catch can line that hooks up to the manifold, does it matter? also should i plug any open holes?

[@rictorkooldude10]

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?

[@johnnystock7294]

Any updates?…

[@MrRobe1028]

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!

[@ThatE46]

So then the CCV just vents to atmosphere since we cut that hose that goes to it?
