this process is going to be similar to all BMW with N63 engines 550i 650i 750i 750Li X5 50i X6 50i
pcv failure is a very common problem on BMW N63 engines causing misfire, high fuel consumption, smoke coming from the tailpipes and high oil consumption.
wiring problem
low fuel pressure
injector failure
sensor failure
timing incorrect
defective or broken engine
bad shifting solenoids
low transmissions oil pressure
transmission oil leaks
transmission sensor problems
etc,...

Thank you…Very thorough presentation! I would bet the dealer would recommend replacing all three components, rather than find out specifically which component is the culprit.
fixing the car the first time is better than playing a game of trial and error with customers cars, that is understandable. but i agree there is easily room for improvement on their end.
Good job talking about the dreaded valve stem seals and pcv valves. You seem very knowledgeable on this engine Francisco. I also live in I.E. and would like to connect with you. Thanks man.
Great job... thanks for explaining!
Excellent video, keep up the good work.
Hello from France et thank you. I've smoke on my 550i, i know how checking pcv valves now. thank you !
Good job you answered a lot of questions thank you
Great detailed Video!⭐️⭐️⭐️⭐️⭐️
You are a big help this car is scary
Most helpful!
Gracias amigo!
Great show 👏
Great video
Good video man very informative and u can tell u know your stuff. Just picked up a used 550i and I have light smoking at these pcv lines thinking of replacing them myself. Where in the I.E. are you located?
Great video. Thank you. What’s the mileage on this particular car,what’s the service history,etc.? Thanks
my car has this problem now . needed to see this before i go to BMW tomorrow to fix .
Hola hermano. Dios te bendiga grandemente a ti y toda tu familia yo tengo un problema con alto consumo de aceite las pcv son nuevas y no hay aceite en los turbos que podría ser
Hi there, do you have a video on the BMW X5M pcv valve replacement? Would love to see this. Thanks from New Zealand
I appreciate the education. I recently payed nearly $800 for a simple oil change at the dealership. Your explanation of the issues with the N63 really shows me how BMW stealerships are getting over on the customers.
Why did you pay that much…. True idiot
@@sirmo667 They didn't provide the estimate up front so rather than argue I paid it. I live in San Francisco so I expect to pay more - I can afford it.
@@MD-xs6fx Doesn’t matter if you can afford it. Why would you let them do that to you???? Stop being a push over
@@sirmo667 I get what your saying but I’m not in a position were I can express anger without serious ramifications. Better for me to be cool 😎
@@MD-xs6fx you don’t even have to be angry, just fair. There’s no way I could ever pay $800 for an oil change even if I had money like that
It would be nice to get some history on the vehicle you were working on.....year? Mileage? Etc. ?
Thank you So much. You have explained everything more than anyone has. They have recalls on bmw PCV problems. Will this cause a sluggish problem, whistle to screeching sound? & A sluggish gear change feeling?
No those symptoms wouldn’t match up
When figuring out if the PCV valve is bad can I just inspect it from the outside or would I have to remove it to look for excess
Hi i have a bmw 750li f02 with the issue of exhaust gas smell in the car. do you know what it can come from? the exhaust manifold gaskets have been changed but the problem is still present
Did replacing the pcv stop the smoking
Got a smokeu bmw n63 2011 650 Wondering that smoking at idle and as soon as I rev it lots of white smoke and also oil consumption.. how can I know if it's oil rings, valve stem seals, turbo,or pcv, or pcv down pipe to inlet manifold or manifold leak, ???? And can you use the updated pcv that does not connect to rhe inlet manifold
Hello Francisco, I change the both pcv valve on my 2011 X5 50i 4.4, and after that the engine start making a squeling noise. Any idea of that? I was thinking maybe the new ones valves are defective.
Same in my E66.
Yes there is just replaced in my m550
Hi, Francisco, I have a 2016 X5M, was getting a powertrain power loss code, injector #2 being shut off. When going into scan tool and checking, it shows history right away and not active. I reset it, good for a bit, then goes into power loss mode again. Have changed the coils and plugs. Ran good for a while, maybe because it was cold and not quite hot under the hood. Also lots of smoke coming from the passenger side as well. Using quite a bit of oil. The plugs I took out were fouled and also a bit on the loose side. Didn't take much effort to remove them. I have replaced the ccv piping on it. The power loss comes on more often after running for a while, like 30 minutes of driving, and will keep going into power loss mode. Any ideas? Thanks
Yo tengo uno igual esta tirando humo puede ser la valvula pvc
Hi, if PCV jest good, oil cup is vacuum, when pcv is bad behing oil cap there wiill no vacuum and engine burning oil. Check oil cap on running engine
Thank you! Great explanation!
Hi ,I have 2011 BMW X6M
And I was getting low oil level on I drive top up couple times still coming up I have zero smoke from the exhust and no oil underneath the car
My mechanich said I have to replace valve seals and all PCV valve and Turbo return lines ,
Like seriously how could all these go bad all at once
I want to skip the valve seals may be just do the PCV and turbo return pipes
Please nay advise would be appreciated
Where are you guys located?
A occ valve is an oil separator smart guy
I took a video of the sound it's making if I can send it to you it would be very helpful
After the crank case tubes/pcv valve tubes were installed on My N63 engine I am getting a chirping sound that gets louder when the engine is turned off. I did not replace the 2 orange seals that see on the bottom of the air box that you did in your video. Do you think those seals can be the problem of the chirping sound
did you find out whats was the problem?
Como puedo limpiar para que yano tire el humo
Thanks alot for clear explanation..
I need yiur urgent help..
I have 550i 2011, oil level comes down 1ltr approximately every 3000 km ... there is no smoke from exhaust... the car is well maintained...
i am suspecting some leak somewhere... down the care i didnt see any leak ..
Do you recommend me to check anything specific
Spec is up to 1L per 750mi in the turbo. Add oil as required.
Where are you located
Great info, just replace them but I have a question, after you replace the PCV valves the smoke will stop?? How long it will take? Does you know?
Does somebody know??
If you only replace pipes smoke will continue. Oil is coming from oil separators under valve covers, you need to replace them
If 550 f10 smile only in idle?
I changed that top pvc valves on both sides now it’s whistling 😗 on the bottom
Amigo tengo un problema con un BMW X6 ,cae aceite por el tubo de escape del lado derecho y consume mucho aceite , pero no bota humo azul , espero puedas ayudarme
tengo la misma situación ahorita, pudiste arreglarla?
😢 my bmw 550i is smoking a little and the pcv valve are broken
I have to add 1 qt every 300 miles. Always has dtmalf cide...but no white smoke 183k miles 2011 750lixdrive
What was the problem please?
Does the oil from bad PCV like the one in this video get into the turbo Coolant, or no?
No it would not. Do you have oil and coolant mixing?
I need some help , i have a p1561 code with misfire code cylinder 6 and 7 . i already change all spark plugs and all coil packs. It starts but dies in 3 seconds . its a 2013 BMW X6 M SPORT 4.4L twin turbo . PLEASE HELP ME !
Timing chain…
do you have any youtube video to replace intake manifold bmw 750li xdrive
Only when the engine is already taken off. With engine in place it is almost impossible to get to nuts that holds intake manifold to cylinder head
I have a similar problem , after being idle for around 5 min , i start moving forward the smoke appears from tailpipes ,Where would the valve stim valves be ? & how to replace them ?
Valve stem seals are in the motor block bro u have to take out the whole motor to replace then
@@kevinmaruky5483no you don’t have to remove the engine, for gods sake man…..
Much easier if you can remove the engine but not necessary
Do you recommend installing oil catch cans on this engine after replacing PCV valves? Will that help reduce the tailpipe smoke?
That’s a good thing, i’ve it on my 550i
And remove the cover
Great vid, i have a question...i have a 2013 BMW M6 f-12 just did catless downpipes from rktunes and i did the tune they sell.....i had to do the rear o2 sensor delete. The car seems to run great...but now has a smell from the exhaust ( expected with the tune ) but also i see a cloud of white-ish smoke coming from exhaust when i take off from a stop ( never noticed it before ). Any advice or start with pcv valves and work from there ?
Thanks and keep up the great video’s
Me too
Ok, so the car does have 79,500 miles on it. I took it to two different places and i am bringing it in for a valve guide seal job. The smoke is progressively getting worse…they tell me the turbo’s and pcv valves are ok.
Goes in this monday to get done, i will let you know if it fixes it
Getting the valve guide seals replaced
I have a 2020 m550i 48k and had the Rk tunes front mounts and vrsf catless down pipes installed. Running Bm3 stg 2 93 ots. . Just noticed some smoke at idle 🤦🏽♂️ . How did your car end up ?
@@venomyzf1977 i ended up having the valve guide seals replaced…stopped the smoke and a lot of the excessive consumption…now i only add oil every 1000 miles compared to the 300 i was adding a qt
Sadly I have bad valve seals 👍🏻
I've already replaced the PCV on both sides, but only the top ones and there's not much improvement. There is no smoking only when adding gas at a standstill. Oil burning didn't improve, maybe a little. I don't know what to do with it? Maybe you can advise me?
At this point after replacing the Pcv it may be valve stem seals I just got hit with this nightmare of the valve stem seals 10k in repairs from dealer.
@@dannyruiz8654 holy shit
No. Bang v BMW is a class action lawsuit where BMW will cover valve stem seals. They did mine $0 under this class action.
Downstream O2 sensors
@@jeffreymedeiros6253 I’m guessing it to late to jump on that bandwagon? If not more info please
Amigo ese problema causa mis fires también
si
2008 n62 4.8l car st idle is rough feels like it’s going to stall. Codes say combustion cylinder 8 misfire other misfires. I changed the plugs and the coils I changed in may when I bought the car. They are fine still. I changed the pcv hose from intake. O2 bank 2 sensor before the plugs and pcv cause I had a code for that one no voltage. I changed that then code for throttle bottle sensor. That code went to catalytic converter low threshold. Then misfire so that’s why I did the plugs now. Car still misfires at idle. When I drove it to see power was really bad then good then bad. Came home. Today switched the coils one side to the opposite I seen your other video to do that. Still misfires from cylinder 8. Any suggestions what to try now !? I’m in New Jersey btw don’t know if your around this area. Thanks for your time and thanks for the awesome explanation of all your work. Your a good man ! God bless you
Salut
Tu dois prendre les compression pour voir si tout va bien
Je pense que tu n'as pas de compression dabs ton cylindre numéro 8.
I have the same problem.
Oil consumption/smoke/ car idling terrible and drive terrible
Low power warning/ English malfunction warning
Every-time I change the spark plug in cylinder 8 it blows in 2/3 weeks .
The fucking dealer wants to charge me 1800 to diagnose
@@48hourrecordsteam45 What did you end up doing?
Can you run a regular n63 pcv on a n63tu to eliminate the hose that runs across ?
No
At the very least You would have an opening in the valve cover that accepts the other end of the hose definitely causing some issues
how expenisive might it be to fix?
Both side PCV Valve come as an assembly with a hose connecting the two sides.. this assembly is $340.00 USD
Then there is another hose “connection hose” that connects to passenger side valve cover to the other side valve
Connection hose $140.00 USD
Then each side valve cover has an
“oil separator” internal to each valve cover. This also comes as a set which DOES include EACH SIDE valve cover gaskets and internal oil separators.
$150.00 for the complete set.
Then it is roughy $675.00 with tax for oil separator complete kit with PCV BOTH SIDES and connection hose and will take you roughly 15-20 hours if you have all the tools and do both sides. If changing internal oil separators
Fan cowl has to come out. Ignition coils. Spark plugs. . Intercoolers need to be separated from engine not removed completely but all fuel injectors need to come out and be resealed with teflon rings AND new decoupling elements but if over 50-75k miles replace all injectors. Another 90$ each for the EU6 variant which is perfectly fine to use for 2013 BMW 750Li XDrive and do NOT need to input injector values to the module. If you get EU5 injectors you will need a scan tool roughy $300-400 for a foxwell scan tool (I recommend) that will work fine to input the 8 injector values. Be sure to write down ALL NUMBER FROM EACH INJECTOR. NEW AND OLD IF USING EU5 verison fuel injectors.
Just use the Eu6 versions high pressure fuel injectors. Also dont forget the high pressure fuel pump gasket each side. I did not need to loosen or remove any coolant hoses. Have enough room to just move everything aside. But if anything is leaking or loose or faulty now is the time to replace it. All 8 injectors come new with teflon seals new on them but need 8 decoupling elements. Roughly 10$ each.
So $850 total roughy for all injectors if you do yourself. Also spend the $300 for the fuel injector removal and installer master tool kit or 50$ for the single tool version on amazon.
Fuel injector removal/ installer tool
Total for entire oil separator system
I have a 550i that is burning/ leaking oil. Does it help to add 15w-50 racing oil to help with leaks.?
I had a strange case f02 750Li, engine have new valve seals, new timming, new injector new sparks and ignitions. I drive the car freely but something is smoking behind me (I think it is steam) but the engine was already at 90 degrees, I accelerate and I still see a little smoke then I drive freely and a cloud of bright blue smoke. After a while everything stopped and so far such a problem did not appear (at that moment I already thought that something broke, maybe turbines, maybe new sealants, maybe something broke?) but that would be all the time and it appeared for a while and stopped And I bet on PVC but PCV crankcase is only plastic pipe so what will do when I replace for new one ? maybe in those PCV are some valve ?
If you replace only PCV pipes you change nothing actually. Because they are only pipes. You have to replace both oil separators located under valve covers
Please check your PCV information. There is no PCV Valve, instead there is an Oil Separator in each Valve Cover, one on each bank; they fail. BMW quoted me $1800 per side to replace.
It’s a shame BMW builds such unreliable junk. This is why they depreciate like bricks. No one wants to own one out of warranty.
