Q: My car's air smog pump check valve went out.

asked by on

So I basically have two pipe check valves on the same pipe line. They both went bad and my problem is I don't know what caused them to break. I'm really hoping they just broke from over time but I can't find anything that tells me how they necessarily go bad. Air is coming out from the end it's not suppose to and was causing hot air. Figured out it's because the pipe check valve is broken and trying to figure out if something else went bad as well. Please help.

My car has 200000 miles.
My car has an automatic transmission.
