2012 X5 3.5ix Oil Leak

AngeloF15 · 04-03-2019, 03:04 PM

I have a 2012 X5 N55 that is also developing a leak where the bell housing meets the oil pan. Some background info, bought the truck with 100k on it no leaks. 5k later water pump went. After wp repair noticed the oil leak. Not sure if this is a coincidence or result of high temps from failing wp. Took it back to the dealer and they said either opg or rear main seal leak. I then removed skid plates cleaned all the oil below. Then i changed the oil and added 2 cans of liqui moly oil saver. 400 miles later the leak persists. Couple half dollar size drops on driveway. Checked vcg ofhg and looked ok. Engine is very clean all around. 3 mths later I rechecked the leak and can now see that there is oil coming from an exposed section of the opg. I guess this issue is worsening but at least I know for sure that the opg is leaking instead of wasting money on the rms. I am in North Jersey and was wondering if anyone had a good bmw shop with experience in changing x5 opg. Any suggestions on a different additive would be welcome as well. Thank you all.

Another member on E90 forum said a leak on the back of the valve cover gasket could be dripping on that area. Any thoughts? If I remove the skid plates there should be some signs above the opg if this is the case. Any help is much appreciated.

Very common issue the oil pan gasket, take it to an indy shop, it's about 1k to 1.2k mostly labor.

Here are some picture from my latest peek under the skirt. This is 400miles and 2mths after using the liqui moly oil saver. I pulled the inspection cap off the bell housing and rms is clean. Looks like its seeping all around the opg at this point so additive did not help me out. Can anyone see any other culprits from these pics? Thanks again.
