My daughter has a 99 S80 and she has an oil leak. It's probably the O ring on the Turbo Return Line. Is this any tougher to replace on the S80 than it is on the 850? I thought I read somewhere where you have to remove something on the S80 to get the line off the turbo. She does have the dual turbo T6. I was going to do it for her, but don't want to tackle more than I can handle. It's not the daughter who is married to the mechanic, it's the other daughter. Maybe I should get the mechanic to fix his sister in-laws car?

 

Good luck they are a pain. It is alot harder to do the S80.
One side is pretty easy but the other side is a B****.
