2005 WRX 2.0. I've been noticing varying smoke out of my tailpipe more frequently; idling or when I give it gas. The exhaust reeks of oil. And I sometimes smell oil in the cabin when I drive. The other day I looked at my turbo and noticed oil on the bearing housing. It seems to be leaking oil out of the hot-side seal. Slowly, but is leaking nontheless. Sometimes nothing seems to happen, other times it's pretty noticable. Is this usual at 60k?
