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.
