POSSIBLE VACUUM LEAK

1995 Buick Lesabre • 6 cylinder FWD Automatic • 159 miles

95 Buick Lesabre
Car stumbles under load. All sparks plugs and wires changed. Then I noticed a hole on the under side of my vacuum check valve. Is this a normal thing. I can hear a hissing sound. Maybe a vacuum leak there? Is that hole supposed to be there? Look like over time the heat ate away the bottom layer of the valve.

Not sure which valve you're referring to but if you hear vacuum leaking, then there is a problem.
