That's not in your head, that's in the crankcase. Are your PCV valve and crankcase vent both clear? Or is it just a worn-out oil cap.

Wouldn't be valve stem seals, there's not that kind of pressure there. It could be rings, which is "blowby".

Sorry, I don't much speak to turbocharging non-turbo motors.
