It looks like I have a leak between the 2 sides of the turbo. Can't imagine there is an o-ring or gasket in there, wouldn't it burn up. Any idea what is leaking and what the fix would be? I've been smelling burnt oil, but only when pulling one of the trailers, for some time. I'm guessing this is why.

Looks like the shaft seals are leaking. Probably gonna have to rebuild the turbo.
