Thank you for your videos! I was quoted over $1,000 to replace valve cover gasket and ccv replacement. I'm a single mom and cant afford that.... so, believe it or not, I did the work myself. I tried the ccv replacement and it was a pain in the ass, so I followed your instructions from this video and my car is running better than it ever has!! The only issues I had were trying to explain to the guys at autozone what I was doing.

[@NathansBMWWorkshop]

+kristin walker You are not alone, alot of people are in the same spot as you on these car, the local shops hate me for these videos but who cares the owners deserve to be able to drive their cars and not have to pay $1000's to keep them up.

[@kristinwalker8601]

Ran a hose from valve cover to oil catch can, then from catch can to back of intake.

[@NathansBMWWorkshop]

You should b good to go, on those cheap catch cans i use o-rings on the top where the metal lines go in the can since they tend to leak vacuum, dont forget to cap your oil dipdtick otherwise it will a vacuum leak

[@nonimportant3505]

Have u cleaned the inside of catch can?

[@Subieadventures]

I’m getting codes I’m running lean guessing my ccv is bad Here my question .. will it pass a state inspection in Texas ? If I do this delete

[@excellenceinmotion9322]

Thanks Nathan!!! I have a 1997 528I as my daily with 147,000 miles. The previous owner deleted the CCV already. However, the the crankcase breather was routed back to the intake and the dipstick was capped. That resulted in a lot of oil being deposited infront of the throttle body. BTW, my car has an S50 intake and larger throttle body (no DISA) I ended up venting the crankcase and dipstick with small K&N filters. I did attach a long 3/8 hose to the dipstick in case some oil were to leak out. All you videos are awsome and very helpful. Thank you for your time.

[@beaferoner]

Hey thanks alot for the videos. I just finished my ccv delete w/ cath can last night. I chose to feed the return line through the stock ccv connection as I have seen many others do. Unfortunately the 3 series doesn't have much room by the intake for mounting the can, so I opted for placing it in the empty battery compartment on the passenger side. Every thing went smoothly except for stripping one of the DISA bolts. Bout to take her for a drive and see if every things ok, just wanted to show some appreciation for the vids, they helped me alot.

[@redraven6691]

How did it all last over time? Did you have any burning oil smell in the cabin?

[@christycurtis3152]

Thanks Nathan! I did the delete/catch-can on my 2006 x3 (m54) after buying a ccv that was too cheap to snap/catch connectors (inconvenient lesson learned cheap parts!) I used old BMW fittings that are strong and snap into place. Hose from valve to catch-can “in” with hose adapter and clamped all connections well; then catch-can “out” hose to pcv valve (yes, installed pcv valve going correct direction) and up through intake connector to a new return hose with solid connections at hose transitions. This cleared all 14 confirmed and pending codes. Only drive a few miles a day but 4 highway miles to town. 5 -days after catch-can install, I’m getting white smoke from exhaust and under hood, coming directly from under oil fill cap. Can smell exhaust in cabin (yes, I know that’s unsafe to breath in). Not causing engine temp gauge to change. No apparent oil anywhere but getting oil change today as oil is bad. Thoughts please?! (Not going back to BMW or local BMW shop who quoted $1200-$3400 for ccv & hose replacements!)

[@halfevilwelding5268]

Ever figure it out?

[@theprodistini2590]

Thanks Nathan. I recently purchased an x5 that was in mint condition but smoked like hell. Fixed it with the conversion. Sold it shortly after for a rather nice profit. Would have ended up spending an hour or two taking the manifold off to replace ccv had I not found this video.

[@99mustanggt09]

If u connect the valve cover to the vacumm port on back of intake it will push air back into the engine causing all the oil to be pushed out the vent on the dipstick lol

[@FreePalestineFromTerror]

The vacuum port make vacuum not pressure? But it will suck the hell out of oil seals and valve train if it is connected that way 🥳

[@bai2629]

Amigo, greetings from East Naranjos, Mexico. After waching this video now I can fix the whole village from mobile Dodge repair van with M50 motor laid in to it. CCV was easy but without this video, so lost trying to get the hose on the separator pipa on a 1999 320i. Nobody could tell how to do it until i wach this video. I have small problem after delete with motor pressure, but I replace with new rings and motor only smoke tiny bit now but only sometimes.

[@BMWe-oz9wk]

I’d stick with oem, typically only need to replace the ccv every 120k ish. So if anything you’ll probably only need to replace it once. But if you want an easier job I’d definitely pick one of these two options as they don’t require you to take off the entire manifold. Just do your research!

[@marcass100]

Antonio Wray what if it goes bad earlier at night? Not after 120k

[@Kashim_o]

Antonio Wray you can replace the CCV without removing the intake manifold. I did it the other day. Just remove air box, intake boots, DISA, ICV, and throttle body.

[@sasiedu562]

I'm catching nothing but oil daily man is crazy how much stuff is your intake but I will say it makes your car run so much better guys

Can someone please explain the first option to me in more detail Pleasee

[@andrewpeters7892]

what did you do with the small hose that came from the fuel rail down to the ccv when you installed the catch can? thanks for the video.

[@daytongriffin5103]

[@bdrook2]

i did it the first way, was venting to atmosphere bc i dont care i use the x5 as a work vehicle but threw check engine right away so decided to hook to back of intake like you did, everytime i hook it to back of intake oil shoots out the dipstick and all the motor oil goes with it over everything, can nottt figure out what im missing, any help would be greatly appreciated, i have to get this thing inspected and it keeps throwing p1092 when vented to atmosphere, back of the intake no code, but then run out of oil in 10 miles and its everywhere….

[@joeylopes6695]

I have this on my e39 the catch can, and it is great. it does keep the intake clean and it is so easy to do

[@omar1990seattle]

Hello! I want to do this catch can system too on my 530xi, but my question is, If I unplug all the connections front the ccv hoses will I get a engine light? How did you did yours

[@oe35]

Hello Nathan, thank you for your videos. I want to hear you suggestion , my 2003 E39 M54B22 125kW engine now in cleaning process because we seen engine burns oil. We will changed all gaskets, suction and exhaust subaps(valves), rings of the pistons, cranck/rod guides etc. And we will replace PCV system 4pcs hoses. Engine block have not got any physical demage, cylinders ok, main cylinder cover ok. When we dismantled all hoses inside covered with oil and black particules, camshaft cover also same. If engine master (my service technician) clean plastic camshaft cover and clean inside the PCV valve, is it enough or we need to be replace these 2 parts also? If I need to change, then how is Febi brand for camshaft cover and pcv valve? Im asking , because we have got huge price for original BMW parts. camshaft cover BMW 900euro Febi 220 euro, PCV valve BMW 100euro Febi 22euro. Actually if good cleaning ok for our dismantled original parts I do not want to replace with new ones. But I do not know inside of the factory pressed oil seperstor section of the camshaft cover wich is really expensive in Turkey. Please share your opinion with me. Regards

[@maxw5156]

Exactly what i was looking for.

[@adamkearns3420]

When deleting the PCV system does the ecu pick up any faults with it not being there or is it as straight forward as it seems?

[@e36fanatics]

no faults

[@Marrkmoore843]

thats what I thought too. it sucked it in. its a brand new rear seal. I put it in a month ago bc I just rebuilt the whole engine bc of a blown head gasket and the block was no good so I got another one. Anyways, I vented the valve cover and the dipstick and still leaking. If the blue devils dont work, I only know one way to fix it and thats tear the engine back down and take the engine and transmission back apart.

[@NathansBMWWorkshop]

+Mark Moore Well Well if you remember when you installed the rear main in the holder it gets tapped in and it has a stop behind it, what about the upper oil pan gasket, did yours have a gasket or just sealer?

[@chasemcdaniel9680]

Does this not consume oil tho not hating just wondering if I did it this way would I have to top the oil off when I drain the catch can?

[@miguelkeener3122]

Thanks for the info Bless your heart

[@motobevy7850]

Is it better to run the crankcase gasses back into the intake manifold? It seems to me to just vent it off under the car or straight to the exhaust is better for fresher air and more oxygen going into your intake. The only problem I could see arising with that method is the car actually wanting to run with the crankcase gases, like it's tuned that way. Or it will adjust itself based off o2 and maf sensor? Any answers to the venting method?

[@David-yh5po]

Great video thanks for sharing this with us.

[@brianandrews7099]

In option 2, is it a good idea to install a universal or generic PCV inline between the intake and valve cover or no?

So the 1st method is the same as on older engines, correct?

[@JusMeChillin]

Correct. It is pretty much the same as a pcv on any other engine.

Is there a conclusive test to determine CCV? I don’t have suction from the oil fill cap, but I do have oil smoke, which seems to only really occur under load. 03 X5 134k. No codes, runs great otherwise.

[@Dr_Noble]

Can you take the factory pcv valve and hoses off and blow them out and clean them with cleaner and it work again if it was stopped up?

[@Marrkmoore843]

just to give anyone who is thinking about switching to a catch can and deleting the pcv valve. be sure you use the hard hose bc I made the mistake of using the hose that came with my catch can and it sucked flat and caused excessive crankcase pressure and blew my rear main seal. Nathan doesn't mention that in the video nor does he mention that you should buy some metal scrubby things that most people use to clean pots and pans with and put 2 or 3 in the catch can to catch the gases and fumes otherwise they will end up in cylinder 4,5,6 and fill them with gunk as well as your valves.filling them with gunk that is worse than having in your intake manifold. Google the catch can fillers and you will find out what im talking about and save yourself a huge headache and use hard or semi hard hose to route the catch can. im not exactly sure what will work bc I haven't but my engine back together but go for the hose you cant squeeze.

[@robertocamilo1450]

I have 1994 BMW 325i, there's no much diy for them. Do you have any knowledge of the pcv valve routing?. I can't find anything on the web. It's an old car and it should be easy to work on them but nobody has inf. Do they have crankcase ventilation? If so let me know how is the routing. Thank you. I would appreciate any help

[@johnkaing98]

Thanks for leaving this response. I have this issue and am looking to find the correct hose for it. Could you provide a link to where you purchased the hose that doesn't bend or flex with the vacuum pressure?

[@kmax7163]

@@johnkaing98I spent 50 bucks on a 3/4 inch inside diameter hose that is advertised as PCV (vacuum) hose. Yesterday i installed it on my catch can system...started it up and it sucked close. I immediately turned off my engine. Wtf? I bought it directly from Radium Engineering out of Oregon. I was pissed...and still am. I still haven't found a solution so I put everything back as stock for the time being.

[@johnkaing98]

k max I was able to solve this problem by purchasing some 3/8 in vacuum hose from autozone and it works fine. It did not get sucked in. I did not route the hoses the same way as Nathan in the video. I did not use a catch can and basically upgraded my valve cover to the m56 aluminum one.

Hey im really sorry for everyone whos car got messed up but listen closely ima tell u how I just won a amazing deal, I just turned 18 and bought a 2006 bmw 530xi for 1600$ thats with title transfer, cars in beautiful condition and everything is very very clean, the lady who owned it said its smoking really bad and she thinks its the head gasket but she does not have the money or time to get it fixed and needs the money. So I bought it thinking simple tear down to gasket and replace reseal and all is well aslong as their are no cracks anywhere. When I did the title transfer with her she gave me a envelope from bmw that had a recall on it for the pcv valve and said that it needs to be fixed she never took it in. I took the car into bmw dealership near me they fixed it for free (I called first to see if they had the part), I now got a beautiful 530xi for only 2100$ (I did a tune up, didnt need it but better safe than sorry)

Where is that plugged vacuum port from factory near the intake boot.. I can’t find it

You don't say what to do with the old CCV hoses and connections. The vacuum side is still connected and I don't know if it will be drawing unmetered air into the system through the CCV.

ok. explain why the oil light was coming on and off. mainly on at stops. it has to be the cause bc I have done nothing else to the car. I took out the pcv valve and installed the catch can exactly how you recommended.now, after driving 20miles, my rear seal is leaking pretty bad. somehow their was a buildup of pressure and the only change I made was the catch can.

This is so hokey, just do it the right way and be glad to did! remove the throttle body to access the crankcase valve and be sure to get a new oil dipstick O-ring. put the O-ring on the tube before putting it back in as opposed to trying to put the O-ring in the oil pan. the first option shown is just bad, the second option shown in the video would be more involved then just doing it the right way. be sure to get a kit with all the hoses needed and watch a good instructional video

Uhm...I'm guessing you mispoke regarding the function of the CCV/PVC/EGR/OSV valve being "to separate the oil from the water"... and meant to say somehing more like "oil from the air" which is indeed one of its function, as well as regulating the presure inside the crackcase to avoid blow-by and blowing out seals in the more extreme cases.

Could we just connect one end of the hose to the valve cover and the other end to the dipstick? I have removed the distribution piece on the intake malifold and blocked the 6 holes using 6 blanking plugs. Fitted 1 inch air filter to the valve cover and blocked the dipstick tube ( where the drain hose would fit from the ccv valve ). Runs fine but it still consumes oil because a lot of vapor comes out of that 1 inch filter.

[@NathansBMWWorkshop]

You cannot loop it to the dipstick , it will create pressure , the catch can is really the best way to go for $15

[@NathansBMWWorkshop]

+Mark Moore The dipstick tube must be capped off with the catch can installed

[@Marrkmoore843]

With the dipstick vented, I still have a little vacuum on the oil filler cap.

how long does the mod take when doing the 1st option ? Using 3/8" hose with 3/8" x 1/2' shark bite male adapter or connector you described within this video does my 2006 have this cap you mention on the intake rear of motor as you describe here? I see the kit to fix this has various prices for cost $39.68 seems to be the least expensive way of going to fix if someone has this problem. i have the new coolant recovery tank installed guy says he burped it so no air was in the system but after driving it on NYS Thruway it dipped towards hot but then corrected itself and remained in the center of the temperature range indicator in the dash cluster. The SID information display says check coolant level, is this normal and i just need to now top it off? or do i take it back to the guy shop and have them go over the system again to double check that they got all the air out of my system? lot of these shops are very shady characters...and you just never fully know whether your getting good to great service or being shafted...and my other post was regarding these: CCV PCV

[@rockiemosley]

What would be wrong with an open pipe setup where you just attach a hose to the valve cover and just run it down towards the oil pan and just let it belch out on the ground like a 57 chevy? And plug off the intake vacuum port and dipstick port?

+Mark Moore Might have to reseal the valve cover, i have had that a couple times, the suction at the oil cap is normal

[@stokes81ks]

Nathan, I have tried the single line conversion for a few months now. It cured my smoking problem. However, my engine now seems to be leaking oil from every available seal. I don't think this is a coincidence. Have I missed something?

[@NathansBMWWorkshop]

Is the hose you used kinked shut? make sure its a heavy hose because if it kinks closed it will pressurize the crankcase

[@stokes81ks]

+Nathan's DIY Garage I have checked the hose and it isn't kinked. I have very good vacuum at the cap but seem to have a fairly large leak somewhere under/near the inlet manifold (possibly filter housing gasket?). Would this leak cause problems to make other seals/gaskets 'sweat' - as that is what appears to be happening. Thanks for the quick response.

[@NathansBMWWorkshop]

Check the oil line going to the vanos also, they like to drip, but the biggest leak could be from the dipstick o-ring, also make sure your block off on the dipstick tube i secure with clamps

[@jimridenour5308]

What did you ever find was the problem

[@streetracingsuriname7980]

Vaccuum at the back of the intake is the problem!!!! You need to use the vaccuum port of the Diagram on top of the Intake.

[@LetsPlayDaPc]

what hose os going to the back of the intake my 99 didnt have one

[@PaulSmith-oy8xp]

Hey everyone - after NOT getting to this (nor installing the "cold weather kit"), I just suffered the infamous Oil Suck Issue: No hydrolock, thankfully...but about two quarts of oils shoved through the engine and out the tailpipe...:-( Before I embark on a bypass approach

[@turdrocket]

Nathan. I deleted my acc capped off dipstick tube and both holes in the intake like you said. left the front hose 1" opening open. and am getting a lot of smoke from that hole under the hood. is this normal?

[@hectorcazarez9857]

what about 2006bmw 550i makes white smoke

[@williamrondon1459]

Hi. How fix this problem my bmw 550i . 2006 Where buy parts Thanks

[@231mac]

Hi Nathan, quick question, I installed the catch can and the car runs SO much better, but I have an occasional oil smell inside the car and also I'm pulling a lot of suction when removing the oil cap when the car is running. Common sense says since I have the catch can installed, that I'll pull a lot of vacuum, but is it normal at the oil cap? Any ideas about the oil smell? Thanks a million for your time.

[@NathansBMWWorkshop]

Hello vacuum at the oil cap is normal, sometimes the catch can can make a valve cover gasket leak worse, i would remove the cover and if the gasket is still soft just reseal the whole thing not just the corners also check the valve cover for cracks, dont forget to cap off your oil dipstick tube rubber line.

[@231mac]

Thanks for the speedy reply! I did cap the dipstick and I figured there should be vacuum at the cap with the install of the catch can. I'm searching the valve cover this weekend and I don't see any leaks as of yet. I'm still throwing P0471 and 0474 codes. And can't for the life of me find the vacuum leak. I even replaced the fuel regulator hose, lol. I'll cigar test it this weekend. Your videos are a huge help and this is coming from a mechanic. Thanks again!

[@NathansBMWWorkshop]

what exact car do you have?

[@231mac]

Nathan's DIY Garage I have a 2002 325I with an automatic trans and 98K miles. Sweet car. I'm going to do the smoke test tomorrow morning.

[@231mac]

Nathan's DIY Garage One last thing, I started hearing a clacking noise from the engine compartment at around 2500 rpm's, when I moderately accelerate. Engine doesn't make any strange noises when you rev it in park. I'm starting to suspect my DISA. I checked it about a month ago and it seemed fine, but the rough idle on initial start up, those P codes and the noise are making me think it's taking a shit. Dunno...

[@thomasdrouin3643]

I have a question.

[@williamcruz364]

Where Can I get The CATCH CAN ?

[@javiesolis8093]

I agree that ccv- is trash... bmw needs to do a recall on that part and a lot of transmission as well !!

[@priceda332]

Nathan -- your videos are great and very helpful. I certainly appreciate the effort you have put into making them! I have a 2004 4.4L with about 180K on it -- it runs like a scalded ape -- but if I sit at a light for a couple of minutes; when I start moving, I leave a very distinct blue cloud of smoke behind me. :( I thought that this engine I have is an E53 (?) but it looks like your videos are for 6-cylinders -- so that makes me wonder if this will work for my 8-cylinder? I've been quoted ridiculous numbers to have this fixed at a shop --> "your valve guide seals are shot and the engine needs to be rebuilt/replaced for ~$6000". WTH?! Any advice/tips/suggestions will be sincerely appreciated. :)Dan

[@SalisburySnake]

You should have an N62 engine. I'm not familiar with them, but you can bet they have a similar oil separating system. Definitely sounds like your problem. Bad valve seals would smoke the most when releasing the throttle at high revs (high engine vacuum sucks oil past the seals). A bad CCV system will smoke the most when accelerating as you said, as the oil builds up in the manifold and pipes when idling.

[@Marrkmoore843]

well, after installing a catch can on my bmw m54 I blew the rear main seal. thanks Nathan. beware because this will cause extreme engine pressure.

[@NathansBMWWorkshop]

+Mark Moore No way i dont buy that for a second, i do this all the time and i never have a problem, the catch can creates negative pressure and there is no way that can blow a rear main.

[@Sroor2023]

Nathan's DIY Garage That's because you didn't install pcv valve from the head Where the hose started so the air will Not go back and hose will not Be sucked as if you didn't put pcv valve

[@marcass100]

Nathan's DIY Garage is negative pressure ok for the engine? On idle there should be big vacuum in a crankcase on a single hose conversion if there is no filter on dipstick

[@grumpyoldrockers1048]

Will this pass smog test?

[@MyRcGoSlow]

Nope

[@sportbike1006]

I did the single line and now the car is blowing white smoke? should i cap off the hoses to the ccv valve? What did I miss

[@NathansBMWWorkshop]

Jon B the hose has to be kinked closed , you have to use a reinforced hose to make the bend from the rear of the intake, lately running a vented catch can without vacuum has been working the best

[@sportbike1006]

I did used reinforced hose and there are no kinks. does the ccv need to be removed or can I cap off the hoses going to it?

[@johnnyboy4882]

If you delete the CCV (oil separator) you will just get all the oil from the crankcase directly into your intake manifold. That's why they put the CCV there. The White smoke you see is the oil from the crankcase being burnt into your cylinders. The single line mod is the dumbest thing I've ever seen, I don't know how this guy can recommend people do it. You will either need an catch can or a new CCV and do the 02Pilot mod.

[@he162a]

No link to parts, thanks.

[@MohammedAli-hu2dp]

Hi nathan,can you show me how to by pass the oil separator on my e52 4.4i ?Thanks

[@NathansBMWWorkshop]

Hello do not have a video up for the e53 4.4 yet, but the separator is located on the passenger side rear of the intake depending on the year of x5 , it runs to vacuum and then down to the oil pan.

[@hobonatilife9357]

Nathan's DIY Garage I also am looking to do this on My 4.to but no info on it. Helppp!!

[@hobonatilife9357]

4.4

[@danielbailey848]

Hey bro. Good video. I noticed that you didn't mention using a pcv valve in the catch can setup. Is it necessary to use one or is it fine without it? Thanks man!

[@als5995]

Daniel Bailey pcv is necessary

[@jerryharriman1160]

What’s the hard line coming over transmission? Small about 3/8

[@LoonAtNoon]

Coolant

[@LoonAtNoon]

Maybe

[@Bigjamez2011]

This does not work for the e90 06 330i

[@ArturoGonzalez-yj8pg]

hi a did this on my 2004 x3 bmw 2.5i but it doesn't have the back intake houses were you recommend I should connect the hose to

[@justingierok703]

did you ever figure this out?
