I assume you mean the the o-rings between the turbo and the EBPV. The waste gate solenoid does not have anything to do with oil.
The turbo sits on top of the EBPV and is sealed with a couple o rings. They can be bought locally at any Ford dealer or ordered online at Diesel O Rings.com
They also have instructions to help you out.
