XC90 Oil leak from bell housing. I
guys, I think I am in trouble, I have a 2013 XC90 D5 with 81,000 KM. I have an oil leak from the little hole in the bell housing ( where the engine and gearbox come together).
For what I read online there are two possible causes:
1) core plug failure. Common on earlier engines but I would expect a 2013 built engine would not have a plastic core plug. To fix it it’s a shit job.
2) failed rear main seal, if this is the case it’s a really shitty job to fix as well.
it is a very slow leak, a small drop so often oil level went down by a very small amount.
any ideas what it could be? Any recommendations for a workshop to fix it? Or is there another component that could be causing the leak.
I have added a few pics.
