Hi, looking for advice. I have a 2013 x6 40d with a now pretty bad oil leak. No mechanic I have asked will even look at due to the engine being notoriously problematic apparently. So its now sitting rotting in my drive sadly. Does anyone know of anyone who would have a look at this in the Ayrshire area of Scotland??

Morning Gemma

Welcome to the Forum

Not easy to Diagnose without seeing the car but lets put the leak to one side for a moment. The engine in your car is basically the 3.0d 6 cylinder diesel that is fitted to many models and has been around for years with a reputation for being a really strong engine. Where it differs is rather than 1 Turbo it has 2 so whoever you have been talking to is just plain wrong it just needs a lot of covers removed before you can see the engine. I am not a Garage just a very enthusiastic BMW owner who has always carried out his own maintenance at home. I have seen 3 X5's with the 3.0d engine that have had oil leaks from the Oil Filter housing and a member on here has had a split Oil Filter housing (different engine) I have also seen leaks from the Turbo oil feeds and return pipes not difficult to fix just fiddly to get at particularly when your an Old Bloke who isn't as bendy as he used to be 😅

If you are not able to DIY Google the Register of BMW Specialists put your post code in and it will find a Specialist near you, I would talk to a few to check costs reference lists etc

Hope you get it fixed

Hello Dave, Thank you for your reply! Yes this is what I am being told, its just too difficult to work on, so Ive been sent away from a few places, one actually being a BMW specialist. They thought at first it was the rocker cover and this is when it was just a tiny leak, however after it was at BMW Irvine for a service the leak seemed to become worse and its now pretty leaky. That's the frustrating thing, its probably something easily fixed but I just cant get anyone to work on it 🤯

Thank you for the advice, I'll keep looking but failing that I was hoping an enthusiastic like yourself might fancy a project and try to salvage this lovely car 🤞

I find it hard to understand why any garage would say these cars are to difficult to work on let alone a supposed BMW Specialist.

You say there was a leak they thought was from the Rocker cover was that fixed? As it got worse after service it could be the leak was at the filter housing which has now cracked due to being disturbed (as said a member on this site has experienced just that)

You just need a decent Garage/Mechanic who is prepared to take off the engine covers and under tray so they can actually see where the oil is coming from. About half an hours effort to take them off (even for an Old Bloke) If the leak is on the passenger side that's where the Oil Filter housing is, drivers side could be Turbo Oil Feeds and Return pipes are.

Don't give up contact a few independents as well as specialists

Dave

Thanks Dave, I've managed to get a garage in Kilmarnock to look at it, so fingers crossed 🤞

Yay well done Gemma

Let us know how it goes 😄

Dave

If the oil leak is coming from the oil filter housing, your oil level will more than likely show too high, as coolant will be mixing in with it. Did this myself a couple of months ago.

Torque setting is 20nm for the bolts.

The other place it could be is the oil filler cap housing gasket, and that’s a 5 min job to do

Which side of the engine is the leak coming free m?
