My turbo developed an external leak and after changing out all the other possible seals first (valve cover, oil filter housing, all turbo oil and coolant hoses, vacuum pump) I went and pulled the turbo and found the seal plate oring was pinched between the intake housing and the cartridge. I am surprised it lasted as long as it did.

Does anyone know what the part number is or have a source for them? I tried to find one by using the size charts but am not confident I did it right (109mm ID, 1.9 CS, Viton).

Thanks in advance.

 

Still looking for answers. ECS? WMW? Anybody?

 

If you can't find it in RealOEM illustrated parts list --- https://www.realoem.com/bmw/enUS/select it probably doesn't exist as a separate item.

 

Thanks. I am very familiar with RealOEM. For those that don't know it has every part BMW spares for the Mini (and many other BMW models) and several that they do not spare. No, RealOEM does not list it. Yes, it is available somewhere as I have seen it as part of turbo rebuild kits and turbo cartridges. I have NOT found anyone who lists it separately for the Mini although I have found it for Garrett turbos and a few others. Just not our Minis.

I am ordering a few generic orings in various sizes to see if I can find one that fits. I can't believe that no one has had this issue before.

 

Have not found that one yet. I will reach out to my suppliers and see what they have.

 

Thanks. I shotgun ordered 8 different sizes (ID and CS) hoping to find one that fits. Would be nice to know what I am supposed to be going for and get the right ones.
