boost control valve is continually sending oil into the turbo intake right before the impeller. Rearranged the valve position so it's hose does not suck from the bottom of the valve (this a Garrett). Is there an explanation for this such as seals? Will a rebuild stop this?

oil was leaking past the front seals behind the impeller and being pushed into the wastegate tube.

Rebuild time. Not too difficult. Make sure you use a run-out gauge of sorts to ensure the impeller shaft is true upon reassembly. Have fun.
