I have an oil leak but am not quite sure where it's from. If it is the o-ring, how much does a dealer charge for service? Also, I have an extended warranty, Gold plan from Mercury Insurance.. Would anyone know if it could possibly cover the work on that? I've had lots of service done to my car using that warranty. What other possible places could I be leaking from, at least most common?

 

turbo or non turbo?

 

2000 s80 T-6, sorry.

 

Could be the Vent box leaking or the turbo return line o-ring.
Both are pretty expensive to repair.

 

Tech, I called volvo today, looks like the part is about 260 plus shipping. However they're calling it an engine oil cooler, are they thinking of the same part??? either way, do you have any diagrams on how to replace this box???

 

It is called an oil trap.
You will have to remove the intake manifold to gain access to it.
Then replace the Vent box/oil trap.
