I’ve been waiting for a video like this forever, no one does videos on the n55 thank you so much

6.38, you had me going! (thanks for posting)

A few comments. By partially removing the intake manifold and not cleaning the mating surfaces or replacing the gaskets, you're asking for an intake manifold leak, as well as for debris to fall into the intake ports or onto the mating surface. You should completely remove the intake manifold, clean the mating surfaces and replace the gaskets. Also, you should prime the oil system after replacing the oil filter housing. You do that by disconnecting the injectors and the coils, removing the spark plugs and turning over the motor. I think you're supposed to do that three times or until the oil light goes off. That way, you know the engine will have oil when it starts for the first time. Finally, to BMW, after decades of producing shitty oil filter housing gaskets, maybe it's time to fire the engineering department.

What’s that’s sharp tool you were using

Do you need to drain oil before doing this job?
