So last night while doing pulls I thought I heard a bit of whining but wasn't sure. After just driving around regularly the rest of the night it started getting louder and louder. At this point I was concerned so I was babying it. It now sounds like the infamous "supercharger" whine but only if its loaded. Starts maybe around 10inHg and gets louder as pressure increases. I limped her home last night really gently so as not to make the noise anymore. Pulled the intake off and no axial shaft play and a little radial but not so much that it can contact the housing, There was a little puddle of oil in the intake pipe and the turbo inlet. But that has been there for quite a while and there was no more than usual. Doesn't smoke under boost either. 200mi old oil. Turbo fed off the head. Ideas?
