I know this is not an X3 forum, but i do own a 3 series as well as a x3, but i thought i would get more assistance on e90post.


I have a small issue. I just finished doing an oil change for my 2007 BMW X3, this is the first time that i am doing an oil change myself on this car in particular. When i first open the drain bolt, the oil comes out like normal, but i also notice that the oil leaks out not only from the drain bolt but a small rectangular hole near the bolt (SEE RED ARROW BELOW), as well as the rectangular door that is just below the door (SEE BLUE ARROWS BELOW) that contains the bolt.


I thought nothing of it at first, but after i let all the oil drain, i wiped up the surrounding area went along with the rest of the procedure and when i put the drain bolt back on (tightly) and the trap door back on, later i noticed that it was leaking oil a lot of oil dirty oil from that small rectangular hole (See Red Arrow Below) and the trap door that contains the drain bolt so i opened the trap door again and wiped everything up and checked the bolt again. But it was still leaking dirty oil, especially after i started the car up.

At this time i had already poured the new clean oil in so i figured it wasn't leaking from the bolt because the oil that was leaking was still dirty oil. Is there another place that the dirty oil leaks from?

when you drain the oil, it comes out so fast that sometimes it splashes into the undertray and doesnt make it into whatever you are draining oil into. once the car is on the ground, it starts leaking out from wherever it can until it dries up.

this, at least, happens on multiple e90's i have worked with. hope this helps

it sucks because it happens every. single. time.

I wonder how BMW drains the oil, do they take off the plastics or do they have a deflector that redirects all the oil into the catch pan?

My n52 2006's drain bolt faces down so this isn't an issue.
