thanks Erik
yes, the disconnect was post-turbo
and yes, the turbo was 'boosting' that whole time, judging by the mess of oil all over everything
but are you saying that the turbo puts out more air than the engine sucks in?
i.e. how much 'suction' does the intake create, vs how much pressure does the turbo produce?
by definition, since the turbo comes from the exhaust, and the exhaust comes from the intake, and the intake comes from pistons drawing down and sucking air in, due at least to friction losses, wouldn't turbo pressure inherently be lower than intake vacuum?
and if that's the case, AND the pipe was disconnected, so at least SOME turbo pressure was spilling, wouldn't there be a fair amount of sucking happening at that disconnected pipe of whatever was floating around under the hood - dust, dirt, insects, loose screws, old oily rags? I'm lucky I didn't get sucked right out of the driver's seat
