BMW 330i 325i E46 CCV Replace & Intake Removal DIY (Part 1) - See It Clearly! P0171 P0174 Repair 

For anyone who is planning on doing this, don't panic. The steps are overwhelming but can be done, you just need time and Patience. I did mine today and took 8hrs, i know...thats a lot. But for someone who is new to diy mechanics, I'm pretty happy with the results. I would like to thanks The50's kid for is great tutorial, could not have done it without it!!!

50s kid: Thank you so much for your videos. I was able to replace the CCV over a 10 day (following your video to a "T" and ordering all replacement parts/correct tools. I really appreciate you doing this: you've saved me thousand of dollars. *** A note: When I fired the car back up, the ABS, DCS lights came on. I checked on RU-vid for those areas and the fix was to: put the car in "N" and turn the wheels left and right....I guess air bubbles where in there? Bam, lights went out in about 8-10 seconds. Once again, you are the best and thank you very much for the video/s.

Best mechanic on youtube

I just completed this job because I had a leaky water pipe under the intake manifold and a CCV covered with oil. This was a well edited video that is riddled with insight and information. Every detail must be followed otherwise you'll waste hours if you follow your intuition. It took me a period of ten days (after day job, weekends) but was about a 16 hour effort. Unfortunately, there is nothing repetitive about the job, each step has a different challenge and you must be careful to not break things( e.g., electrical connections, DISA valve, throttle components) in the process of removing and installing. I experienced two very difficult issues that I never thought would take 7 hours of my effort and a couple of notes not addressed in the videos. 1. The ground wire that looks like a O2 sensor took me 4 hours to figure out how to connect to the intake manifold bracket. Look carefully how 50sKid tilts the manifold in order to hook it. Intuitively you think you can do it after the manifold is mounted but you can't because the casting on the engine block and the starter motor are in the way. You must insert prior to mounting intake. (Part 2 of his video) 2. The second delay I experienced was the installation of the fuel rail. I did it per the video (Part 2) but my injectors didn't line up and I could not insert the clip correctly. I knew something was wrong when my engine cover did not align with rail holes Had to undo work which is difficult and time consuming, but had to do it to see what was really going on. For what ever reason my injectors seemed too short, so I removed my injectors and attached them to the fuel rail first and then inserted into intake all at once and enough for o-rings to attach firmly into manifold. 3. 50sKid is very detailed but doesn't show the removal of the two connections that are in front of the engine. They are connections that run between the power steering reservoir and oil filter. 4.Car had a rough start after job was completed but computer eventually got everything squared. My car even stalled as I went around the block for testing. Started up again gave the car some more time. Two hours later no check engine light and car running like a champ. This video saved me about $2500 in labor, not including parts My DISA was falling apart, my CCV and respective connections were a mess, vacuum lines had holes, and both water pipes and hoses needed replacement. My intake gasket was as thin as paper. I spent $500 dollars in parts, so I know mechanics would of had a field day with me and justifiably so. There is a lot of work involved. Thank you 50sKid! Look forward to other videos. Would like to see you tackle steering and suspension issues and maintenance.

just did the procedure on my 330 just like you've shown on the video. Went like a cakewalk, took about 4 hours. Fixed the rich condition and rough running when starting cold. MIL light is out. 50sKid, you are the best. :)

Sir, YOU SAVED MY WALLET AND MY LIFE with this video. I fixed all of my vacuum leaks and my car purrs like a kitten now. My level of confidence for getting deeper into my engine has increased tremendously. Now that I have done this, I’ve noted several other jobs that I want to undertake to fix my 2004 325CI. Thank you!!

Hey 50s, I just wanted to say thank you to your instructional video. My dad and I just did this project, and it worked out great.

I decided to just push the BMW off of a cliff instead.

Wow, thank you sir!!! Your videos are the BEST! I love how you think and explain your thought process. I'm an engineer and I really appreciate your rigorous and detailed approach. You are making quite a difference in the world helping us to cope with the crazy BMW implementation of it's exotic engineering ideas (and vulnerable, inadequate plastic and rubber hoses, clips and seals!!!).

Great production value, thank you. Thanks for the different angles, "b-role", and closeups. Also, thank you for going through the struggle (getting the tube on) as well to show options. Also, thanks for showing us how to clean properly as well and not just talking about it.

Thank you so much for your videos. Just bought my first Bmw and determine to learn to do the maintenance my self since I had a bad experience with an 05 A6. Never done more than oil change and spark plugs. I'm getting code p0174 inspected the car and notice the drain tube from the ccv was cracked closed to coming off. After looking at lots of info & videos, yours gave me the confidence to tackle this. Just got it done this morning and glad I did it since the drain hose was clogged. Your videos are easy to follow. Next VCG. Thank You!

love the video great quality tells me everything i need to know and more.. im so tired of random videos starting with the part removed or skipping the entire removal. I really appreciate you putting time into this so they viewers can understand completely. Now going into this job with a lot of confidence!!

got it!!! it was the bigger connector to the throttle body was not locked in place . man I was so happy to see it ,put everything back in place ran like charm. Thanks to the 50's kid you rock.

I want to thank you for your excellent, detailed and user friendly videos. This video outlined every detail telling me what to watch for and how to proceed at each step. There are a lot of RU-vid videos on the BMW e46 but none that equal yours in quality and content. Thanks again for saving me hours of work.

I've been having p0171 - p0174 for about a year and I searched all over RU-vid and Google for CCV guiding video and couldn't find any, until you uploaded those two awesome videos. I'm planning to do the job tomorrow as I have received my parts today. thank you so much for the videos.

Hey 50sKid, thanks for all the careful detail! It was very helpful. I just completed the job, could not have done it without this video. I did not remove the intake manifold because your video educated me in knowing how it all came together.

50’s kid, you are one awesome tutor ! Thanks for sharing your brilliant expertise! 🙌👏

50sKid You are spot on about struggling to get everything back in without removing the intake. I learned that lesson the first time I changed my CCV & hoses. Took me all day with my fat hands and I still don't believe I got the hose that connects on the left side of the CCV with a locking collar fully locked since I couldn't see or really feel it. After blowing my head gasket I decided to do the gasket change myself. I couldn't believe how easy and fast I got the intake manifold out & how easy it was to reach the CCV & all the hoses!! After the rebuild I was throwing a couple lean codes & my mechanic said it was probably a fouled CCV & to change it out. I already had the cold weather version I had bought for the rebuild but didn't install it cuz I thought the old one was still good...lesson learned. To install the CCV this time I disconnected the manifold and flipped it up to change the CCV out. Having removed my intake components a few times already I got thru this job in about 2 hours! This is the way to go. As you pointed out in the video you have to be careful with removal/install of the 10mm nuts that hold the manifold to the engine. I lost a couple myself during the rebuild & had to order new ones. Taking them off this time I loosened to the end of the stud and used a pick up magnet to turn them off the last couple turns. I used a piece of electrical tape to hold the nuts into my socket to put them back on. I wish your video had been up a couple years ago when I changed the CCV the first time. Thanx for posting. This is the only way to do it if you have big hands and can't get them into that tight ass space to lock the left side hose into the CCV so you don't have leaks. Thanx again!!

Terrific instructional videos! I've watched a bunch of vids on ccv replacement and other maintenance how-tos, yours are by far the clearest and most useful. Thanks a bunch!

I REALLY appreciate your videos. Watching you, I've replaced the valve cover, oil pan and oil filter gaskets. So helpful. This is my next venture.

Thank you so MUCH for all your E46 videos! Your step by step tutorial and Torque spec mentioned are so helpful. watched video couple times, took notes and took pictures on Iphone during the process just in case. The job itself was not difficult at all. I have also done the OIL PAN gasket and transmission gasket replacement with your videos. i have to say, the OIL PAN gasket was the hardest job ever, but now i know what to do in order to get the engine re-align with the bolts and sub-frame. Could not have done any of this without your vids. Thank you so much!!

Thank you soooo much 50's Kid! This video AND Part 2 helped IMMENSELY! I needed to replace the CCV and hard coolant lines...I kept a laptop on the workbench and referred to the vids often! Not only with the information invaluable...the the narration, video quality, and camera angles were exceptionally superb! Keep up the GREAT work!

Your video's have rejuvenated my love for these BMW series. Just completed my repairs also, thank you.

Thank you so much for this video. I finally gave myself the entire weekend to do this before the Pennsylvania winter arrives. I shall see if this fixes my excessive oil consumption on my 2003 325xi. I appreciate your time and effort in making this video. Thanks, man!

Just wanted to thank you. The last 2 weekends I replaced my vanos rings and replaced my broken lower oil separator pipe. A lot of work, but your attention to details and calling out tools needed was fantastic.👍

I was really impressed with the work you did,explanation it was so clear, great camara thank you so much. that was a lot of help, great job

you are my favorite mechanic on youtube. God bless u man for your efforts.

Dude, I did this while watching your video 11-16 times in a row. My car is all good now! Thanks a million!

I did my entire cooling system but I'm thinking a shop should do this for me as I might break something. I've done some work on my car thanks to you and your videos man.

Just finished this job on my 2000 e46, no codes by lots of oil leaking. My CCV was toast! Your videos were invaluable. THANK YOU SO MUCH!!!

Big day today, Some TLC for my chariot - 2001 325i 133K kilometres, full cooling system refresh (except heater core), all new gaskets and vacuum lines, CCV, crankshaft sensor and both camshaft sensors, clutch fan delete, OFHG, Oil and filter change, Transmission oil/filter change and pressure valve update..... 11 hours to do the job including fixing things that broke when I tried to remove them... the plastic pipes under the intake manifold broke when I tried to move them. But all worth while, the old girl is running like a Swiss watch now. My thanks to those who put up videos especially the 50sKid....I appreciate your efforts Jason, makes it easier when you know what to expect and how to do it... saved myself about AU$1.5k in labour charges.

Thanks man. You're right. I'm in the process of replacing the ccv on my wife's 2005 BMW X5 and it's hard enough doing it with manifold off. Thanks a lot. I really like your videos, especially those which shows where you made some mistakes and show how you corrected them. You're for real dude.

"This car is perfect" he said, "you won't have to do anything for the next 5 years but change the oil!" He said...2 days after I bought the damn things the service engine soon light came on, codes say it's a pcv valve, also has the far right vacuum line broken off. Your video's are saving me money & sanity. Thank you so much.

Thanks for the videos tons of help !!! saved me from sleepless nights trying to remember how everything goes back together

Thanks a lot for your help. You have saved thousands of bimmers from the junkyard..

Great video! You do a really good job of providing an explanation right down to the hardware sizes.

Thank you for the videos, I purchased a E46 in pieces and your how to videos were a major part in getting it running again

Just want to say thank you Jason for your video, It was very helpful when I had to do this job over the weekend to replace the leaking heater pipe under the manifold. Your video is spot on and very detailed, there were no surprises. It's rare to find someone who is very knowledgeable, detailed and excellent camera & editing skills. You saved me a ton of $$ again, so thanks! To other people doing this job, consider what TonyS mentioned on an alternative way to install the injectors and if your car has over 200k, consider replacing the o-rings on the injectors and the manifold orange rubber gasket as well as they were already hard on my car.

Been a mechanic about 40 years. But never worked on BMW. But now that I own one it's a must. Ur information was very helpful and explained perfect as I went through the process. Great job👍 Thank you

I've been working on a BMW that would misfire on start and idle badly. I replaced the plugs, fuel filter, fuel pump, and then it only misfired at idle with fuel cut-off (P1343 and P1351). I didn't think it could be a vacuum leak from a cracked CCV until I watched this video. I checked under the engine, and sure enough, the CCV is covered in oil (along with half my face lol). So, now I need to immediately replace the CCV system. I can swap that then hope it will idle smooth again. If nothing else, I'll know the CCV is not going to cause problems! Thank you 50sKid for this video! It's a great resource for us DIY mechanics.

Part one finished, now I have to wait for my new ccv to get here. Awesome video, never worked on a Bimmer before, actually very fun car to work on so far. Thanks again for the awesome video.

Just finished the job for the second time. Removing the Intake is the only way to go, trying to jam a cold weather kit in with the manifold in place is too difficult. I ended up cracking the middle between the cyclone and the diaphragm on install. These directions are perfect! and yanking the manifold is pretty simple. Have your gaskets and a new CCV kit ready to go, and you'll have everything right in a few hours. Thanks!!!!!

Just wanted to let you know your video was awesome and accurate! I just got done doing the CCV replacement. Saved a friend of mine $800.00 in labor costs. They wanted $150.00 for the CCV kit. The CCV kit was $40.00 online.

Thanks for the valuable info, replacing 3.0 on a x5 with my son. got it out and in out the top, but had to take transfer case off to put new motor in. steering linkage obstructed installation. Great videos

Thanks for the great video. Finally changed ccv and ended up replacing all my vacuum lines too.

50s kid, couldn’t have done it without you. A couple critiques and words to the wise. I greatly regretted not marking my electrical harnesses. It takes mere seconds to set up a key system with duct type. Just mark both the female and male connectors with 01 or A, whatever. Putting everything back together will be much simpler. Also, it is very important as you go to mark plastic baggies with wear the bolts/nuts come from. Again, this makes everything so much easier and less stressful on the backend. I had some trouble identifying vacuum lines because they were already severed. If any one needs help on that just message me. Lastly, I did not remove my fuel rail, I simply pushed it to the back, worked fine. Thanks for you me hard work buddy.

Awesome video got my ccv out and reinstalled, it gave me a chance to fix Disa valve also . I cleared the codes and has ran better than the day I got it .

Your video helped me a lot when I replaced my CCV last year. I did not have to take the intake manifold out but because you've shown how to connect the hose from the oil separator on <a href="#" class="seekto" data-time="1553">25:53</a>. I also think that using an OEM parts made the installation easier because of better fitment than some after market parts.

Very helpful video... saved me considerable money ($1k+) & learned a lot by doing this & other repairs from some of your other videos while I had the engine apart. Really appreciate the quality of the video & insights!!

Thank you so much dude. Used this today on my wife's car and it worked so well.

Thank you so much for these videos man, helped a bunch doing it this weekend. Ended up not needing to remove the intake manifold as my hands are small enough.

All your videos are great! I'm in the process to replace the ccv hoses. Thank you!!

<a href="#" class="seekto" data-time="1133">18:53</a> the part i was waiting for Thank you

Your video's are awesome, easy to follow, full of valuable knowledge. Having to remove so many parts to fix a frick'n hose is crazy. It's almost like the engineers designed the system to keep an active revenue stream for all the labor involved.

i got a 2001 330i idles rough now this video is going to help me out alot thanks so much.

Just replace the PCV and starter in my 2003 bmw 330ci thanks for the video, It was SUPER HELPFUL !!! prob saved me 2-4 extra hours, Thank You Thank You !!! AWSOME Videos

Thank you 50sKid I'll check that to day you don't know how much I appreciate thank you again

For whatever reason I can't find a video that mentions this but something that helped me a lot while doing this is there's a bracket that holds the electrical box it's held on by two t25's if you take those out and remove that bracket you can see clean through the other side where you're putting the hose to the CCV valve it helped me a lot that way I wasn't guessing working blind and I also removed the power steering reservoir the two-13 bolts took them out push it to the side took off the bracket and it made everything so much easier (if your replacing CCV with manifold on)

great video. Just replaced the ccv on my E46. couldn't have done it without these videos. I live in Maine. I got the cold weather kit. it was installing fine until I tried to body of the kit to the intake manifold. the foam insulation was too bulky. It wouldn't fit. The one that came off the car didn't have the foam insulation so I took it off the new one. I didn't want to, but everything i tried didn't work. After removing the foam insulation, the system went back together without a problem. Thanks again. Steve

You're the man dude, thanks for all of these videos

I've just discover your chanel, and i love it ! It s so helpful thank you so much :) !

fantastic video!!! thank you! too many people try to do how to videos and leave so many steps out. kudos bro!

excellent video, thank you for making this. I was able to fit the CCV without removing the manifold this was possible in part due to steps and precautions in your video. couple of recommendations to add, after removing the dipstick and it's o ring pop a bit of clean garage towel into the dipstick hole and if choosing to fit the CCV without removing the manifold then apply a small amount of lubricant to the hose joint between the cam cover and the CCV this will assist greatly when pushing that hose into the separator, with the limited space and the o ring the joint is a real pain until you lube it and then it clicks home nicely. last job to do now is refit the dipstick which proving a struggle - onto part 2 to watch your recommendation

50skid, i wanted to tell you that your video helped me out tremendously. I did the job on my 02 330i 162k. did the ccv, looked at the starter brushes with very little wear , all new vac lines, all new coolant lines, alternator brushes and a bunch of other stuff. I may go ahead and replace the oil pan gasket idk yet. Thanks for the video. it was very easy to follow and I wanted to personally say thank you!

I've done it I had post through hole and twist through hole after 20 minutes my engine still has has slight suction do you think the head could be going

Just finished this job. It seems overwhelming at first but just follow the steps and all will be fine. I have a Canadian model and noticed some differences, a vac line or two and a wire connector he had that I don't. After putting everything back together and starting the car it still ran shitty. I checked a plug on the back of the manifold that I new was brittle and split and taped it up snug and slid it back on, now she runs pretty good. MAF might need cleaning.. not sure though. Anyway, thank you 50's Kid. You're a hero

Thanks for all you do, Keep Up the Great Work!

Awesome video as usual! Im doing this today and totally agree that its going to be so Much easier to do with the intake off.

You are the best! you really know what your doing............and I've learn a lot! thank you so much.

Thank you. Very descriptive and informative. Professional level quality!!!!

nevermind after watching part 2 answered my question. great video thanks

Nice Videos. The dealership did my CCV and after watching your video, I am not missing it. I am, however, looking forward to replacing my oil filter housing gasket. I will review your video for that one before I begin. Thanks,

Best video everrrrrr!!!! Thank you so much

man i wish my car was as easy to work on as yours... seems like no one has ever replaced these parts.. such a pain in the arse but thank you for these videos! a massive help

thank you for all the info your videos inspire doing the job

thank you thank you 50s. you saved me $2k. really appreciate your work.

Seriously want to thank you for the videos you make. I just had to replaced my starter and the shop wanted over $700 to do it. Wouldn’t have been able to do this without your videos. I love how detailed they are. You rock.

These videos are awesome. I changed my valve cover gasket, plugs, oil filter housing gasket, coolant, vacuum hoses, DISA valve o-ring, and CCV oil separator to dip stick hose with the help of these videos. Was leaking oil all over, P0171 and P0174 codes, were coming up. all cured for less than $200 in parts. Also changed the thermostat, idler pulley. and fan clutch a month ago. probably saved $5k on my 2003 330ci. Thanks 50sKid! One note, instead of taking on the whole CCV job, try changing out just that broken hose he mentions, it's all I did and problem solved. Took about 30 minutes.

"Inspect you dipstick after you get it off..." PRICELESS! Thanks for a great video and some unintended comic relief.

These vids are excellent! Thanks for the help. This job was daunting, but now that I've done it I'd agree that it's not that big a deal. Knowing how the injector wires detach was a little tricky, but your vid helped a lot. I've got a '99 E39 with the M52TU and have something to add: There are two fuel lines and not enough room to remove them from the fuel rail on the rail side. You can disconnect them where they meet the hard lines and it give you enough room to move the rails out of the way.

Great work and good video with good instructions. After all, it seems that intake manifold is not so difficult to remove after all.

Such a good tutorial I love this guy!

Congratulations. perfect explanation. I do not know English. I found it easy, to explain calmly, gesturing, showing with great focus. very good. just an opinion, make a list of the tools you need in writing. at the beginning of the video.

Thank you, thank you, thank you. I'm by no means mechanical but with the help of this video I was able to do this repair!

Great video!! Very helpful!!! Thanks soooo much!!!

Fantastic video, thank you very much.

More info on your video and much appreciated 50's Kid .Thanks !

Thank you for clear explanation. Got the job done few days ago. <a href="#" class="seekto" data-time="1572">26:12</a> was the way to go. did it without taking the intake manifold off. THANKS> I suspected the ccv to be the reason for excessive oil consumption. If it doenst get better than maybe i go the catch can way. (but first ill do the oil filter housing gasket.)

Long time no see you , you are the best

Following this video now ! Thanks you sir!

i subbed. keep making videos about e46's. Your videos are great.

This help me out alot. Thanks man

hey 50skid :) thanks for the vids .. just removed my dip stick to find that some one previously has lost the oring :D

Great video and easy to follow. With the Euro 328i models and the brake booster etc on the opposite side it's a little different. Also the fuel lines are different as there are two lines with one being a return line. The sucking air jet pump is underneath the inlet manifold just above where the metal flap that goes down onto the engine block. The evap solenoid hose and the line to the sucking air jet pump should be fitted before the inlet manifold is put back on. By removing the panel that covers the heater fan motor I had plenty of room at the back of the engine and didn't have to disconnect the fuel lines.

That looks a bit of a nightmare. I once knew almost as much about Austin Minis a David Vizard (because I read his books). My bottom of the range Peugeot is complicated compared to an Austin Mini. I probably could afford a BMW with some of the jobs available to me. My life is complicated enough without a complicated car. I never was career minded. At 56 years it's a bit too late to think about mortgages. I'm just glad I survived a cycling accident and recovered (apparently) 30 years later. Thanks for uploading this - I often wondered how complicated BMWs etc were. I was brought up by a Victorian which may explain if I or my comment seem strange. Horses, carts and village pumps!!

I've been waiting for this!!!!

Like a Surgeon, Great video!

I just did the ccv replacement job without removing the intake manifold. I found it easier to fish the hose from above and then fit the hose to the ccv positioned horizontally and then twist it into place.

your video are great and useful, thanks

what you did at <a href="#" class="seekto" data-time="1580">26:20</a> is the correct and fastest way to install that hose but, the oil separator "must" be bolted to the manifold in order for that to work. There is no other way to do it while the manifold is still attached. Great video!
