Maybe it's my PC but I see no attached pix.
What I use to find vac leaks is spray carb cleaner on suspected areas, which is flammable so the eng revs up when it sucks it in.
I'm guessing intake gasket leak but I'm not familiar enough with that motor to know what else it could be. Like the PCV system, which if the hose popped off or broke etc would cause your problem.
