How is the car performing? Does it idle rough? Stall? Do your brakes feel normal or is the pedal harder than usual? This could indicate a vacuum leak in the vacuum line going to the brake booster.
Besure to check the PCV hose for cracks or leaks (follow it from one end to the other as well as any vacuum line which attaches to the same vacuum source as the PCV).
There could be other sources of a vacuum leak as well so check all vacuum lines (large and small).
