oil from the turbo, exhaust side
i have an 05 wrx. in the last few months i've had a few instances of smoke from under the hood...i pinpointed the source as the turbo/dp connection. when i installed my bellmouth i reused the gasket, which could have contributed. so, i took off my dp to check things out...i have a fair amount of oil in my intake tract which i know if pretty normal, and will be looking into catchcans soon. but i noticed there's oil in the exhaust turbine too. i found there is a very small amount of shaft play in the turbo, almost not noticable. I drive pretty agressively.
so is this normal after only 30K miles? or could there be an additional problem? i am stage 2 AP with a protune. I'm thinking of trying to get a new turbo under warranty, but don't want this to happen again if there's something else i can do to avoid it.
