- BMW N63B44 Engine
BMW models : 750, 650, 550, X5, X6
DIY Job completed : 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. Often misdiagnosed to be leaking rear main seal or upper oil pan gasket. The problem is well known and appears on all bmw`s with N63B44 ENGINE - (F10)550, (F12) 650, (F1) 750, E70 X5 50i, X6 50I
⚠️Symptoms: Oil leaking under the car between engine and transmission. There is a drain hole above the rear main seal, letting leaked oil drip down from the V-valley.

great one boss,keep posting such videos
GREAT JOB,
Thanks 😊
Hi, nice video, is it necessary for the alternator to be removed?
yes it must be removed, in order to get out alternator bracket..
was this oil leak causing the engine malfunction warning to come on? I have 2011 x5 50i E70 N63. I believe same as this BMW
I was loosing oil, that is a common oil leak on this engine.. for the warning light scan the car
Torque specs for all this??
Did any of that have to be torqued
Hi sorry for the incomplete video, it was not easy to capture all, cause I was alone doing it. Honestly for me the most important to be torqued was the oil return cover 10Nm .. All the rest is mostly clamps, isolation, hoses etc..
exhaust manifolds as well 20 Nm
Exelent, it would be just little more helpful if you showed how to disconnect turbo oil drain hoses and how to connect them. I mean the pattern, since that is the most complicated job because everything is pretty tight once you return turbos. Also bank two bottom manifold clamp installation? How? No space! You didn’t show that .
How did you screw torx back the vacuum tank under lower head shield ? I am ready to put back together but can't them screwed in.
I did it, with small rachet .. but you can try with small spanner and torx socket short one
@@SuperFastDriver Heh, also tried with mini rached. But was going in little by little and end up stripping end head ( likely was able to go back and remove so going to attempt with spanner tmrw. On a side note maybe you would know, so originally i had metal vacuum tank just like on your video, but new came as a plastic although same part number. do you know if it's new replacement by bmw or mistake ?
@@boriskaraoglanov strongly recommend you do not put the plastic one.. it is for updated version of N63B44TU .. find the metal one
jag har en 750 med samma motor som misständer efter 20 min körning. får felkoder om att olika cylindrar misständer aldrig samma undrar om det är tjuvluft? har du någon erfarenhet av det?
did you replace your injectors? They must be index 11 or higher
Can this issue also causes smoke 💨 coming out the muffler ?
unfortunately.. no.. most probably you deal with bad injectors if black smoke.. or if it’s blue.. bad stem seals
@@SuperFastDriver thank you
