Decided to check out the throttle body and make sure its clean because sometimes I get a flutter at idle when warmed up. Just wondering if a slight film of oil inside our intercoolers is normal. I did have to add just under a half quart of oil after 2k miles after my oil change, some warm city driving in there too. Again does this sound normal for our cars? It only has about 5k miles on it. I realize turbos leak a little oil just by design. Wondering too if the crankcase ventilation vents before or after the turbo? I've never owned a Subaru before and all the hoses seem to disappear under the intake manifold. I'd rather ask than tear apart the intake.
