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.
+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.
Ran a hose from valve cover to oil catch can, then from catch can to back of intake.
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
Have u cleaned the inside of catch can?
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
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.
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.
How did it all last over time? Did you have any burning oil smell in the cabin?
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!)
Ever figure it out?
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.
Hey Nathan, I did this CCV delete to my E 53, and I have had problems with vacuum issues. I had lots of problems with his car but I like driving it so much I am willing to work on it. What should I have done with the CCV output from the intake?
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!
Antonio Wray what if it goes bad earlier at night? Not after 120k
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.
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.
Drop Performance would also like to see
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
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?
no faults
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?
In option 2, is it a good idea to install a universal or generic PCV inline between the intake and valve cover or no?
no need
@@hmongkieyaaj1491 what about back fire?
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….
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?
Mr Nathan Can I Just vent The camcase right to atmosphere and seal The dipstick hole? Tqvm
Can u make a video with the whole proses and wat u do with exiting hoses
besides everything shown in video all you have to do is plug the dipstick drain port and youre good to go.
Can someone please explain the first option to me in more detail Pleasee
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.
Nathan's DIY Garage Hi Nathan, I am a fan of you. Always watch your videos cause I can tell that you have knowledge of the way the BMWs work. I do have a question dough. 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
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?
@@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.
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.
k max if you have problems let me know I can snap some photos of my setup that works flawlessly and help you out.
How much suction should there be after a catch can install as mine sounds like opening a soda if I open my oil cap
Hi Nathan, cheers from Mexico. What you do with the hose that comes from the botom of trhe fuel rail? Would I need a pcv valve inline?
Gracias
do you have the euro engine ? 520, 523?
Where do I get the catch can do I already have it on the motor? Problem with my car is that I have an E36 Z3 and I'm not sure how similar it is
So do you just leave the oil separator hose that’s connected from the ccv to dipstick under the manifold hanging
so then do you plug the intake lines that go to ccv aswell or what happens with them ?
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.
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
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
Where is that plugged vacuum port from factory near the intake boot.. I can’t find it
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
Any chance you can show me your set up?
, 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
Cap it off
hey Nate this Ty quick question if seeing white smoke can you just change the "Crank Case Vent Valve(s)...on the E53 2006 X5 3.0i sport activity vehicle?
just bought the same oil catch can kit off ebay, definitely need to do this my m54 2.2 its on 105k (miles). Not showing any signs of the ccv on its way out but I don't want to wait for it to happen
+red i predator You are getting close to failure at 100k
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.
1997 BMW 528i M52 ... I asked this same question on another of your videos...Do I have to Remove the CCV to do this Bypass...or just leave it in place.... and Hose from the Front Valve cover to the Rear Intake and then Plug or Vent the Dip Stick hose ? OR can I leave the CCV in place but put a filter on both the Valve Cover hose and a filter on the DipStick Hose ?
Mr. Nathan please answer a question for me as soon as you have time. I’ve ordered my oil catch can actually very excited however I have a e90 with an aluminum valve cover can you please send me instructions on how to do this delete. I can’t find info on any forums on internet. Really was hoping to do this ASAP. I do watch your videos I feel you are a very knowledgeable man on these things and I certainly would appreciate any info you can provide thank you
By the way it’s a n52 if that matters thanks again
Which port on the back of the intake did you hook it up to? Pretty sure I saw 2 or 3 of them on mine.
I think it doesn't matter,I know it's maybe a bit late😂
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?
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?
Ok I know this is a very old video but I need some help. I bypassed my OSV on my E39 540 (M62tu) and am running a catch can now. But literally it's full within 30 minutes of driving and I just don't know what to do. Is there a way to fully delete this system or safely block it off?
I have a catch can on my 540i as well. Your can should not be filling up that fast if it is check the oil level make sure it’s not too high. I’ve never heard of that problem before
Lmk if you did fix it tho I know it’s been 5 months
What you do with the other components under intake?
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
Can this be done in a M62TU in an E38? My oil separator behind the timing chain has failed. I'm trying to bypass it but now my oil leaks, I'm guessing it's coming from the ccv which is brand new
just got finished installing catch can. is it normal to have a large suction on the oil filler cap? also, I unhooked the hose on the catch can coming from the top of the valve cover just to see what was happening bc im curious and it was blowing a smoke mixture out.is this normal? thanks soo much for answering all my questions through out this conversion.
+Mark Moore Hello yes it is normal to have suction at the oil cap after the catch can install, and the steam from the valve cover hose is normal.
Why my mini cooper smoking blue after i drive it for 10 to 15 minutes then i stop when the engine is on then i accelerate it some smoke exit from my muffler?thsnks for response and good day
Block dip stick or vent 🤔 I read venting will spray oil all over?
don't block it, its there to allow crankcase oil/fume pressure to exit, run it to the catch can if possible, or have a long hose go up then back down.
@@justrockon426 thanks was kind of figured but wasn't sure!
@@justrockon426 nice corvair also!
@@LoonAtNoon not mine, o just took it from the web, my grandpa had one red convertible. i have a e92 328xi, hence how i ended up here.
So the 1st method is the same as on older engines, correct?
Correct. It is pretty much the same as a pcv on any other engine.
was wondering witch catch can on 2004 e60 m54 with or without breather and 2 Port or 3 Port catch can
Nathan, Great video,...thanks. 2 questions: Could a bad CCV cause oil consumption on a 2004 X3 3.0? Where do you recommend purchasing the oil catch can?
+Brian Collins yes it will cause a huge amount oil oil usage, get the catch can off eBay
Just using a small amount and no smoking at the tailpipe
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.
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?
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.
+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?
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.
Hey Nathan, I installed the catch can and drove it today for about 20miles and it was dripping oil on the exhaust and running down the bottom of the engine on the transmission pan. also my oil light would come on and off. what do you think is causing this?? I have no codes coming up and the car ran great. also have a HUGE suction on the oil filler cap.
+Mark Moore Might have to reseal the valve cover, i have had that a couple times, the suction at the oil cap is normal
I've done the cvs twice 242,000 on my 2002 e39 . this repair sounds good but emission insp. is my issue. also info on Trans. failsafe program with brake warning lights . symtoms on my car are intermittent light knock on warmup in the trans bellhouse area and while driving intermittent lost of power, feels like loss of electric or fuel and a few seconds later I get the idiot lights then it drives normally, for now
+raymond yanger If you live in california and have to pass the sniffer test you will need to run the oil catch can, your loss of power would have to be icv or a coil pack, any codes would be helpfull
+Nathan's DIY Garage Thanks for the prompt response it is appreciated from Texas! I will pull up the codes and get back to you. Thanks Nathan.
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
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 🥳
If anyone can help me out that would be great, i current have a 2004 x3 2.5 , rough idle and stumble, multiple misfire codes and lean codes, large amounts of suction at oil cap. lots of oil in intake believe ccv has failed, has random clank sound as well which people have mentioned happens when delete is done incorrectly. thanks would like to delete but have heard to many horror stories a chinese ccv and hoses is only $30
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.
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.
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!
what exact car do you have?
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.
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...
Nathan, couldn't you just put a small breather on the valve cover like an old chevy or ford eng?
Do I need a 3/8 ID hose for the back of the intake?
I have a BMW X5 2008 4.8i what do you recommend ?
Hi Nathan! I delete the PCV in my X5 e53 and the valve hose go to the atmosphere. 4 day later I have a leak code. Can be this? Thanks!
yes
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.
You cannot loop it to the dipstick , it will create pressure , the catch can is really the best way to go for $15
Nathan's DIY Garage when using the single hose conversion, which hose do you plug it into? 3 holes on the back of the intake
Can you do this on e38 4.4?
Hi, is it possible to remove ccv, and just plug the hose to intake, like an old m50 engine ?
ok. I have a new one on standby. ill do that today. do you think I should put blue gasket sealer all the way around the gasket or just were the vanos meets the engine head? also does the catch can have a inlet and outlet or it will work either way?
+Mark Moore Dont use blue rtv, but do use ultra black or mega grey all around the gasket, check the cover for cracks carefully when its off around the bolt holes, it does not matter which is in and which is out on the catch can.
Ok. One last question. What about the oil pressure light coming on and off? It seemed to come on at idle and off upon acceleration. Its got the right amount of oil.
Oh, why not use blue rtv? It says oil resistance and high temperature.
it always leaks, its more for like a thermostat housing
Im doing this to my car, but where do i connect the line from.the fuel rail that went to the ccv?
Hi its is any way to do this on 4.8 engine?
I just drove 20miles with everything the same except I vented the dipstick and no oil pressure light came on but I don't think it ran as good.
How do you vent the crank if the breather port on the dip stick is plugged
Thankyou for your Videos. I have a Japan spec RHD 1999 E39 528i. I have done the single hose CCV delete conversion and blocked the dipstick port. Now I have a P0505 fault code I cant get rid of. I ended up removing all intakes boots and checked them for leaks. I have replaced the ICV with a second hand unit. I did have a perished vac hoses running from manifold to sec air valve which I have replaced. There is a check valve in that line white/black. Which way round does it go? I have tried both ways with no joy. The car starts instantly but idles high when cold. When I pump the throttle the car revs to approx 2000 rpm then as it comes down it stumbles and then ASC light comes on and ENGINE FAILSAFE MODE. My car has a fuel regulator on the end of the fuel rail that used to have a vac hose to the CCV. What shoukd happen with this hose after the delete? I have check ed there is slack in the throttle cable as per you P0505 video. Any help much appreciated
plug the small vacuum line that went to the ccv, your icv needs to be cleaned and inspect the rubber hose gong to it, also if the throttle cables are too tight it will cause this exact problem, make sue they are not holding the throttle plate open at idle or it will cause the icv code
Got it working. It was the throttle plate inside the throttle body stuck shut. A lot of black gunge glueing it shut. Thanks again for your videos
ah ok good to know , i glad you got it running
what happens if you just disconnect the 3 vacuum lines?
Do you have to take the intake off to do this job?
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?
Is the hose you used kinked shut? make sure its a heavy hose because if it kinks closed it will pressurize the crankcase
+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.
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
What did you ever find was the problem
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.
I put the gasket and sealer were the rear seal meet the block. torqued to specs.oh and the rear seal bracket has a new gasket that seals to block.what you think.
+Mark Moore The only problems i ever had from a catch can is a whistling noise if your valve cover is cracked and that dipstick o-ring or problems with the dipstick tube hose having a leak if it has a pin hole in it.
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
did you ever figure this out?
I now have the valve cover tube going to catch can and the other side of the catch can going to the back of the intake manifold and the dipstick tube vented and the two holes on top of the intake manifold closed off. having it hooked up the way you stated, I could barely pull the oil filler cap off and I couldn't pull the dipstick out.
+Mark Moore The dipstick tube must be capped off with the catch can installed
Its soo much suction that I think it might be sucking all the oil out the bottom of the engine or something bad bc my oil light kept coming on and off and it just started with the catch can. Have you ever experienced this?
With the dipstick vented, I still have a little vacuum on the oil filler cap.
No and i have tons of cars running them, as far as the suction goes yes the can pulls hard on the crank case just like you stated, a good working ccv does it too just not as much as the catch can.
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?
This is what I bn thinking bout doing
Exactly what i was looking for.
Thanks for the info Bless your heart
Hi Nathan, Thank you for your videos! I have a 2000 528i touring with the m52tu engine and I'd like to use a catch can instead of the CCV. I looked through your videos but I think I missed what you did to the fuel vacuum line that connects from the fuel rail to the middle of the ccv (the small tube that the m54 doesn't use). Did you cap that line on the fuel vacuum line under the head cover?
I just cap it off, do not forget to cap off the oil dipstick rubber line also
+Nathan's DIY Garage thanks!
what hose os going to the back of the intake my 99 didnt have one
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!
Daniel Bailey pcv is necessary
Hey, I just got a 1996 328i and I'm wondering, does this bypass work on the older M52s? My CCV was deleted but the breather hose is literally connected to nothing and the vacuum lines are all blocked off.
On the m52 you can just put a catch can on the valve cover tube and not hook the other side to vacuum, i have video up of the m52 delete on my channel
Hey Nathan, on the 1997 528i m52 if using a catch can, it's only hook the inlet of catch can to the valve cover and the other inlet of catch can just let open to the atmosphire or do we need any small air filter? Do we need also to cap off the dipstick oil hose from ccv or just let open (should cap off or should open) if using a catch can?
oh, do we need also to put a pcv valve if using a catch can on the 1997 528i m52?
Thank you :)
hey Nathan, where I connect the hose to the back of the intake, it doesn't allow alot of air through. I know this bc the hooked a hose to it and blew and it did let air into the intake but it felt restricted. is this normal?
+Mark Moore By holding your finger over the plastic nipple it dont feel like much but once you hook a hose to it and hold your finger over it it actually has quite a bit
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
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
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?
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.
Do I need to cap off all the CCV hoses? Or just the dipstick? Thanks!
install the rubber plug in place of the dipstick, then cap the dipstick tube, never cap the valve cover tube , you need to leave it open or run it to vacuum
+Nathan's DIY Garage sorry, I guess I should have been more specific. I meant if I left the ccv valve in, do I have to cap off all the hoses when I disconnect it? Or can I just by pass it and leave it in? Thanks for these great videos!
if the hoses are disconnected from the valve you do not have to bloc off the valve itself
Great video thanks for sharing this with us.
Hey, I installed my catch can by using the port on the back of the intake. It fixed the idle issues but now it's causing oil to leak onto my exhaust manifold. Just installed a new valve cover gasket and it didn't help. any solutions ?
Did you ever figure it out?
@@marc8979 yeah. I took it off and replaced it w/ a new ccv kit that I bought on ecstuning.
Hopefully you dont get a back fire in the intake.😮
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.
I'll start out by saying thank you. I was stuck two hrs away from home and while this trick didnt get me home, it got me to my city. I followed your other video where you didnt mention you could put a straight hose from the valve cover to the intake port so I left the valve cover opened. Down shifting to 4th blew my valve cover gasket due to excessive pressure build up and now my car leaks 1 qt every 7 mins. Wish you would have mentioned the straight hose in the other video. Regardless thanks, but next time, pleases try and be a little more consistent..
Would this fix my problem with pressure building up in my valve cover. It's odd to me when I take the oil cap off and has all the pressure built up and blows off.
Hi.
How fix this problem my bmw 550i . 2006
Where buy parts
Thanks
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
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.
What’s the hard line coming over transmission? Small about 3/8
Coolant
Maybe
Hi nathan,can you show me how to by pass the oil separator on my e52 4.4i ?Thanks
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.
Nathan's DIY Garage I also am looking to do this on My 4.to but no info on it. Helppp!!
4.4
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
very helpful ... i thought about a similar solution for my E46
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
Complete delete without catch Can?
Nathan, does this supersede your video on removing the CCV?
Nathan, does this procedure supersede your video on removing the CCV>
I have the same question
I know, an old video.. They make barbed adapters in plastic and metal so you don't have to use threaded fittings on hoses.
Will this pass smog test?
Nope
