M35 multi oil line for turbo bearings

[Andydieselpower]

We have an M35 that currently has a small leak on the oil line that feeds the turbo bearing. The line going to the fitting on top of the turbo is dry but the connection to the engine block is leaking.

I've never replaced one of these before- is this just an o ring that seals these?

Sorry for lack of pics.

Thanks,
Andy

Have you tried snugging it up? No O-ring, metal to metal surface I believe.

It seems pretty snug currently.
