Also, there is a 1"OD hose coming off the valve cover with a T connection for the normal PCV hose. The other section of the 1" hose goes to the intake manifold behind the throttle butterfly. Could this hose be providing all the extra air?
Everything is a bit tight to work on... I don't have small Korean hands either.

PCV system hoses are a common leak item. the intake area and the components mounted are suspected ..propane works good .. you do have a very large leak..
at idle the throttle plate need be closed. stuck open EGR will cause the engine to stall and run poorly due to reduced oxygen into the intake. then though the egr power head could have a vacuum leak..
