- BMW X5 E70 XDrive50i Turbo oil line replacement
& Oil return cover replacement.
One of the known issue in the N63 V8 engines. Temperature under the turbos get too high and the oil return cover gasket fails under the heat shields. In some cases the heat also causes oil to "boil" inside the return lines clogging them.
Same problem with 550i, 650i, 750i and X6 50i with V8 engine.
Symptoms: Oil leaking under the car between engine and transmission. There is a drain hole above the the rear main seal, letting leaked oil drip down from the V-valley.
(Often misdiagnosed to be leaking rear main seal or upper oil pan gasket.)

Good job! Refreshing to see someone else who actually cares about keeping stuff clean.
In the automotive world, a job is only as good as it is clean!
Also really nice editing :)
TK-R I respect your skills and knowledge. Thanks for sharing!
That is a lot of work for just replacing the oil lines! Holy cow!
Yes it is. And it's lots of work to replace anything in BMW 50i engines. It is so packed under the hood and tear down takes hours.
What's a job like that run?
avoid 50i... notorious
Actually it's very easy compared to turbos mounted between the engine block and the wheel well as some might even consider dropping the subframe. It takes some time for the N63, but it's very, very accessible!
I'm definetely thinking more about a 550i!
Thanks for the video!
What would it cost for that perfection? Amazing work.
You remodel bathrooms that look showroom quality and in your spare time you rebuild BMW engines. Dude! You are my hero..
Just got done doing that to my ActiveHybrid 7. No alternator on that car so saved a bit of time, but what a pain overall!
Awesome video. Perfect angle to see most everything required. Thx for making this !
im impressed how do you remember were everything goes? wow. great job. I have a 2010
Great video. It'd be nice to list all of the parts that need to be replaced during that process
Parts list is in my first comment on this video
Thankful I don’t have to dig this deep into my clients car. Just did an oil pan though. 😂
Please help me in removing the clamp which bolts exhaust to turbo. Did spend almost the whole day removing 1 of them i.e. driver side. Also once we remove the clamps and the t30 s to oil return line is anything else needed to remove the turbos?
How many hours was this approximately? I am considering upgrading the turbos on my G15 but not sure it's worthwhile.
this problem will be repeat .. two turbos between engine heads without cooling ... great idea engeneers from Munich ... :D :D :D
Yes it probably will. Many N63's have coolant leaks which causes turbos to run without cooling. Also the Aux pump sometimes fails or battery is too weak to run coolant 10mins after engine shutoff.
Ford does this too on the Powerstroke 6.7.
None of these problems exist on that platform. 🤔
Great work!
How did you get the first manifold bolt under downpipe? I’ve been trying for a whole day with no luck. Advice is highly appreciated! Thanks )
any special tools needed to remove the turbos???
I've just done this, took two of us 10 hours.. shockingly horrible job and limited access.
Excellent video and nice clean up. I'm in the middle of the same job on an X5M. What are thoughts on adding turbo blankets to protect non turbo parts?
Sorry late reply. I don't have experience on blankets. In theory they might save valve stem seals from overheating, and all the rubber and gaskets near turbos. X5M S63 runs a bit lower coolant temp and does not have so many issues.
Hallo do you have before smoke on idle when you put gas
good video like the music !!!
Can you provide all the part names (and we would be best friends if you could include part numbers) for the parts you replaced? Looks like you hit a few gaskets while you were in there and I’m needing to have this done. Great vid! Cheers
See my first comment on this video. Part list is there already..
TK-R can you provide again the parts no. I couldn’t see your mentioned parts to any of your comments.

How much to do mine ?
My name is youssou from Gambia 🇬🇲
turbos still alive afterthe full return lines?!
Unbelievable but yes. I think there was still a small channel for oil to flow. Probably got completely stuck when I removed and twisted the lines.
I can't find your version of "Cheri Cheri Lady". Who is the artist/album for this version you have in your video?
It's still Modern Talking. Some of the Chery Chery Lady remixes. I don't know the year the remix was made.
Awesome video. Thank you for sharing. Dealing with broken injector retainer bolt right now. Actually not the bolt but the threads in the head are stripped out. I am going to tap the cone right at the shoulder to the oversized m7x1 inserts that use I believe an m9x1 tap. Drill for the set is included in the “Timecert” 7x1 thread repair set. Drill, Then a chamfer then tap then thread in the insert (10mm of threads on the insert. If this fails I will remove valve cover and do it correctly. Lol. Any experience on the 2013 n63tu motor? Not sure how different it is than the n63 with regards to the above parts. Question… Do you know if the turbos have come out to remove the valve cover?
2013 bmw 750Li xDrive 4.4 V8 twin turbo N63TU motor. Any comments or advice would be greatly appreciated! Seriously though, awesome video man. Thanks again
Would it require the same amount of work for the 2010 X6 Active hybrid?
Yes!
Do mine! How much?
What year is this n63? 2012?
2011 X5
Perfect I got it down! After 1 million pauses and stops. 😂. Great Job! Bro.
Came for the music, stayed for the bmw
Came for de miusic
Awesome video! Thank your for showing. Maybe it will help someone reading this: Check your Turbo auxillary coolant pump, to make sure it's running while and after (~25min) you run the engine. That typically fails and leaves the turbos hot, oil hot, and allows the oil to boil and clog the oil lines. It throws codes, so check that, but doesn't throw a check engine light so may go years unnoticed, so with heat soak you'll get cooked oil and clogged lines. To check that coolant is flowing after the engine is off, just touch the left hose that leads to the pump, you should feel vibrations from the impeller and turbulent coolant flow. The feed line to the turbos also has some vibrations, but less. You might be able to feel it during engine running, but will be difficult. I put an ammeter on mine to check it, but that takes some wiring mods. Hope that helps some people out! I've had two pumps go in 15,000 miles, so beware, it's a weak part prone to failure, and can lead to clogged oil lines and Turbo failure. It has also been the part that lead to some recalls. (Updated: I show how to check in my last post)
David.
Thanks for your good comment! Definitely worth to check the codes and AUX pump operation every once in a while
Good advice. Another simple thing you can do is to avoid driving hard the last few minutes before you switch the engine off, and to let the engine idle about 30 to 60 seconds before you do so. This just helps excess heat to dissipate. I learnt this with military turbo engines.
@@roadstardelta Great advice!! It's always very hard to refrain from going hard, but I'll definitely do that! It's kinda like the turbo timer on the old cars.
Definitely worth doing to drop the temps and increase turbo lifetime.
Thanks for the advice! Myself and everyone else who reads that and idle to cool down the turbos will benefit!
Cheers,
David.
@@roadstardelta Excellent advice. I got 260K miles from Mitsubishi Mirage Turbo engine with original turbo before selling to collector, no oil consumption, great power by 3K (synthetic) mile oil changes and allowing the turbo to cool down before shutoff.
Helo brother.
My engine n63 f02 110000 km ..
Is very hot overheat engine temp...
Maybe whats the problem? Thank you
Nothing pairs better with German car repair than Modern Talking eurodance remix :D
Well okay, you can mute the music!
T K-R music is awesome. Good taste. Keep up the good videos.
The music is cool
Cool
I loved Modern Talking 80S -90S.
I.......will not mute the music
I love the Modern Talking mix to go along with this disassembly and repair. And so thorough and precise in cleaning everything up prior to reinstall!
u hot tho
Very satisfying to see how you cleaned the engine before installing the new parts, a clean engine is a happy engine 😃

I appreciate these videos, my mom went ahead and purchased a 2010 750i recently and after i looked at all it problems im gonna have to dig in . Not my first rodeo but never seen or touched an N63 so every bit of info helps. The car is actually pristine with only 13k miles but im still going to get into it to try and remedy the common issues as well as give it a little more umph . My mom doesnt drive hard at all so it wont make much of a difference with the extra power, but I find it necessary to battle the extreme heat due to this terrible engineering nightmare lol.
That mileage is crazy, congrats to her, how’s it been?
@@Kyronsk8 it rides like a dream , feels like a brand new car despite the age of the vehicle . Currently have it in the garage as it’s getting some upgrades .
ARM intake
VRSF downpipes
84degree thermostat
Oil Cooler valve upgrade
JB4 Tuner
Downpipes, turbos , intercoolers and manifolds are all being Cerakoted . I’m not really doing this for the power as it is an older lady that will be driving it , but more so to keep cooler temps to save the motor from the typical problems caused by stupid engineering decisions lol .
More than ready to beat the brutal southern humidity and have peace of mind it won’t start dumping oil .
@@JAK1981 lmao I can see how all those upgrades can help with the cooling, but the jb4? Yeah I wonder how you convinced her to do that 😂😂😂
@@Kyronsk8 well I need the JB4 to tune everything together so it runs right , otherwise without a proper tune it could cause issues and run rich .
As the car will have power capabilities it can be tuned to just run smooth . Besides as fickle as these transmissions can be it won’t be at the track or racing on the freeway lol.
@@Kyronsk8 besides don’t underestimate my mom , she can drive haha. Back in the day I had a 500whp STi and she handled that just fine .
The song “Little old lady from Pasadena” perfectly describes her 🤣
I enjoyed that first song way more than I care to admit. Had my dad bod cutting shapes like Terry Crews in White Chicks for 4 minutes and 47 seconds Thanks for that.

Btw. I'm playing this song at my wedding 😁

@@timlawz the problem is
It's a BMW 😅
After watching this I don't think I'll be getting a local x6 2009 50i. I liked it and it has great service records but at 130k I don't want this kinda headache. I have years of experience as a mechanic but this is to much 😂
what a nightmare. I'm dealing with this right now. I was able to remove both heads without removing the engine.
now i know why this is such an expensive job :D ")
We bought a 2010 X5 N63 motor, motor needing service related repairs 100k kms. I will be removing the whole thing to do a full re seal and anything that they are known for. Probably the piston rings too. This video has given me so much clarity, I really appreciate it.
Nice repair of a badass engine! Considering one of these to pull my car to the track? When it's tuned, seems like it runs great!
Exactly what I needed to watch plus the Modern Talking in the background makes this a top tier video
I wanted one of these so bad but all I find on the internet is problem after problem with these cars I feel like as soon as I buy one with 50,000 miles it's going to break 2000 later
At 1:54 would that also be a good time to clean out the intake valves which will be full of carbon buildup?
those are exhaust valves. carbon would have been burned off
This engine uses an "inboard" exhaust configuration. On this setup the exhaust and intake locations are flipped. The intake manifolds are located on the sides of the engine under the valve covers, and the exhaust manifold is located up top in the valley pan. They did this to save space. There is no room to mount twin turbos in the conventional format. The Ford PS 6.7 also uses this configuration.
As for carbon blasting the intake tracts, well on the N63, one does that through the wheel wells.
Tearing one down now and its on the tougher/ involved setups especially with that hot vee and coolant lines and I've been on main line at dealers and indys. Once you try you get it.
Btw.. does the poster know if a rebuild in turbos was needed for the mileage the car had? Thanks.
I didn't open the turbos. I'm sure there were some burnt oil residue so cleaning the oil channels might have been good idea. Anyway no play in axels and wheels were spinning smooth.
Amazing video, I think I have a semi problem on my 2011 BMW X5 xdrive50i 😟
I also have a 2011 50i. Did you ever find out if this was your issue? If so did you repair yourself?
Yes I do it
@@philipshroyer6522 yes I do it
thank you for the video. mileage? approx how long it took you? (1st time?)
I imagine this can happen on S63s as well
Great video! looks extremely complicated. I am an owner of a 2011 550i with this shitty engine. Can only go 583 miles before I get the add oil light! What a joke!
my X6 50i 400 miles 1 l oil :)
Ferenc Holczknecht maybe the turbos?
Ferenc Holczknecht or it could be piston rings
If you are in US, you can now take your car to BMW dealer and ask them to do "oil consumption test". There was a class action lawsuit and settlement includes instructions for dealers to complete the consumption test. If the test fails you might get repairs free of charge.
T K-R You are correct! I am getting new valve stem seals as I type this. 12,000 value!
Where are you located? Can i have some support? I have a 2013 501 x5 heavy smoking and shaking, i think i need the same job. Any contact number? Thanks.
Holy shit! I know this video is 5 years old, but Modern Talking? Really?
That's 40 years freaking years ago and the 1st Gen MR2 was brand new...
So how much would that labor and parts cost?
How the hell did you managed to get to the bolt of the clamp thats connecting the turbo to the exhaust manifold???
Clean neat and professionally done👍🏻
Great job!! Can I ask what did you use for cleaning?
I think I used Armor All Wheel cleaner. It's goof stuff and cleans everything!

I love the design, but obviously a maintenance nightmare.
too much heat.
Terrible design, and no excuse for it. Mercedes TT V8 doesn't see half the problems these do.
I just completed this repair. Took roughly 20-25 hours over about 2 weeks with 2 of us. Parts came to roughly $550. This completely removed the burning oil smell coming in through the vents. I've yet to see how much difference it will make in general for the vehicle consuming oil
What part did you order? I have the same issue and smoke coming out the exhaust too
Have you seen a difference yet ?
@@ValuableShort it didn't completely fix the smell. Sold the car.
hi there what'd use to take off the stud bolts under the catalytic convertors? what size socket/wrench combo?
it is so cool to hear Modern Talking and fix Ultimated Driving Machine. Right.
Total respect to your work and to the video quality and edit.
Thanks!
look like i am doing this soonif it is 8K job, the seals on my turbos are leaking.
I need you to do this to my n63tu, you are wizard in tour craft, I can only dream of doing this to my own car
Inspirational! Just completed similar project and this video was very helpful
I'm glad if this video helps!
I have a 650 i and I can honestly say it’s just not worth it thank god for Japanese cars
I wish this engine came with less plastic and better set up for cooling.
Do you know the torque specs on the exhaust manifold?

I need to do this to my E70. I think I could do about 65% of this (with three weeks in the evening), but would need some support for the other 35%. Wonder how I could find a good advisor/pro that could fill in the gap.
You work very fast
I have a 550i 2013 change the pcv valves because they had oil in them change oil to 5w-40 and it still smokes no check engine light on
This seems way easier than my E53 valley pan was. I am considering a 750i with this motor. CCP and trans recall completed.
As someone who owns a 750i xdrivre, make sure to only get the G12 chassis an above. So anything MY 2016 - after. These cars have the N63TU2 engine variant, which eliminates all the oil and leak problems of the past
About how much will this work cost at a BMW shop? I am losing oil but already replaced the oil pan gaskets. This may be next...
If I remember correct the estimate was around 2k USD at the Dealer. Individual shops might do it cheaper..
Instead just buy a Toyota! You will never have this problem! The new supra is coming! It will last fore....wait,what? Someone told me the new supra Have a BMW engine! Oh men.....
@Samuel Murzyn Fuck Yea ! Fuck Toyota ! X6 xdrive50i here.
Samuel Murzyn yeah, but you’ll be stuck on the side of the road in 20k miles and having to do this repair on this shitty boat anchor of an engine again. You’ll learn one day...
I have the exact car. 2013 x5 xdrive50i n63. I’m trying to tackle this on my own and haven’t talked myself into it yet. I definitely want to replace all the oil and coolant lines and turbo return housing. I know there is a ton of oil buildup. There has to be. My car has 120000 and runs like a clock
Neat video! What were the symptoms that suggested the oil return lines were so clogged? What's your opinion on the long-term reliability of the N63, given the rash of issues related to turbos, injectors, batteries, and valve-stem seals?
I didn't have any symptoms on turbo oil lines. I believe the oil was still flowing through and they got completely clogged only when removed, twisted and splitter apart.
I wouldn't recommend early years N63 to anyone who doesn't like to DIY. Newer 2014--> N63TU is more reliable because improved design. These are crazy expensive to maintain if you take them to shop because engine bay is so full that it takes hours of labor to replace anything. Valve stem seals are the biggest problem after 70k miles. Injectors are under BMW warranty for 10years.
Every owner should keep their battery fully charged and replace it often enough. Battery power is needed for the turbo coolant pump, which MUST run after every engine shutdown for 10 minutes or everything will be cooked under the hood.
Thanks for the reply. When you say "turbo coolant pump," does that refer to the electronic water pump? The N54 (in my 335i) has that as well, which runs after car shut-off.
N63 V8 has 2 coolant pumps. The main one is belt driven, and the auxiliary pump is electric. The electric pump runs 10-30min after shut off to cool down turbos.
mrmax1984 I think he is referring to n63’s intercooler’s water pump system. The n54 is air to air cooled, the n63 is water to air cooled . Thank you for the info TK-R!
How many hours shop time would you estimate ? Wonder what an indy shop would charge for labor and parts...
Can’t I find this video anywhere not speed up?

Tenias algun problema con el vehiculo antes de hacer esta reparacion??
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
Any chance I can get a little bit slower version with audio instructions? I’ve had two shops do thousands do dollars of work for a coolant leak they can’t fix so I’m going to do this myself what you did in this awesome video! I need your help pretty please!!!!
My engine is leaking from the bell housing and also in the front coming off a/c pump, also seen oil under alternator and when i shut my car off I see smoke coming from turbo area so I'm guessing that I need to pull my turbos and do this.. yikes.
How did u get that bottom bolt off of the left turbo Ive been trying everything and can't get it it's the ones to the oil feed on the bottom
Warranty will pay this guy 4hrs for all his work. Because they did the entire job with the engine out of the vehicle.
I severely need to do this on my f15…. I thought it was my valve stem seals causing oil consumption but pretty sure it’s one of the turbos
I`m about to get 750i and only can read bad stories about this engine. What have you done to yours (seen the videos, thumbs up!) and is it still running :D
I understand this is for turbo oil return lines leaking into the valley and down the back of the engine. I have a lot of smoke (burning oil) coming from the top of the engine, seems like oil is dripping onto the exhaust manifolds or something else extremely hot. Could this be the same issue or does that sound like something else?
The heat shield with oxygen sensors the bolts at back of heat shield rusted any advice on how to remove them? Also how hard was it to remove turbos and exhaust manifold pls I see in video you tried to reach in for some time before the exhaust manifold came off .... if you can clarify how hard to remove these thanks
As long as bmw and mercedes keep producing junk ill never have lack of work, talk about job security.
You did a hell of a job! Left everything squeaky clean! I'm the same way...
Signed a fellow German auto tech
Thanks for the video. My coolant is low, I cannot see the leak, but I can hear leak after the engine is off. This video definitely help. Do you have the information on torque spec?
@T K-R I'm doing this job right now. What is the sensor that's attached to the turbo? I accidentally broke the line that's attached to it...not the connector, but the thin line (I didn't expect it to be brittle).
Unnecessary to takeoff the alternator unless you replacing vent line 👍🏻
thank you, I was wondering why he had to go upfront
Can you tell me how long did it take you!?!!
Any help with the torque specs to all this stuff?
I was considering a 2009+ 750i or lexus ls460,thank god i didnt get the bmw nothing but problems on those v8s.

Someone tell me price for this work in dollars ?
Bardzo dobra robota 👍👍
Great video, but heat is still there, how long until next failure? .BMW use to be a great brand , I hope it will be again but nos with N63 engines.
I am a BMW enthusiast but why should an engine be so complicated?
Gotta squeeze all that stuff somewhere. Also controlling emissions is a big part of the complication.
Power & efficiency came at a price. It’s really not that complicated.
This is the biggest boat anchor BMW ever made. Stay far, far, away. I work on these for a living. BMW died in 2005 with the introduction of the N series engines, the e90, e60, etc. Egregious design principals and practices.
