engine bay oil leaks

[john-freda]

Hi and happy new year to all, More problems with my 2008 x3, gawd, I hate this car and if the wife didn't like it it'd be long gone!!!.

So now I appear to have a slight oil drip from the engine bay, I cannot actually see the leak, but it appears to be from the oil filler, this appears to be a common problem om BMWs???

My car has a 2.0 N47 diesel, and this looks like a right pain to remove the oil filler and replace the gasket, Has anybody done this job with the N47 engine? any tips would be welcome. 

So far I have had to replace the turbo ( twice ) and fit a new gearbox, this car would be costing an absolute fortune if I had to be using a dealer. Not impressed!!!, 

Mind, I do have a BMW bike which I quite like!!!!.

Thanks for any information received.

Hi John

The BMW remote filter system is a common source of leaks normally the "O" ring under the screw cap is the culprit very rarely renewed even by Dealers. I always use OEM Mann Filters after having an after market one break up in the housing, now that was a royal PITA to get all the bits out.

Happy New Year Good Luck

it's me again, well I bit the bullet and managed to renew the gasket and 'o' rings on the filter / cooler my car (x3 n47 motor) this was an absolute sod of a job, anyway, I am  gutted to find that I still have an oil leak, this engine space is so tight I just cannot see where the drip is coming from, even using a boroscope I just cannot see the leak.       When I am under the car with motor running the oil seems to collect on the transfer box and drip. Has anyone got any ideas, suggestions, experience. please.

Hi John

If the drip is at the transfer case are you sure it's Engine oil ? There is an Electrical Connector to the gearbox that often is the source of leaks (another "O" ring) Unplug the Plug the connector is a twist lock affair with the "O" on it 

Hope that's it
