check valves coming off manifolds

I Have a check valve on each side of the engine that goes to the manifolds on one end and the other end goes to two valves on the passenger side above the valve cover, The two valves are part of the air pump system I believe,
Problem is I broke one of valves where the rubber hose hooks up, Can I just leave these unhooked for now without causing any problems?? It does gurgle now when decelerating which is annoying but I can live with it for now.

You may end up with a vacuum leak while you are cruising.

Obviously something is not going to work as designed if you broke something.

You should try to plug or cap what you broke to avoid a vacuum leak.

Damn I read my first post today and even confused myself,

The Line I broke is coming off one of the air pump check valves above the right valve cover. The rubber hose runs to a check valve above the rear of the drivers valve cover, and then a steel line runs into the exhaust manifold, Their is also the same setup for the passenger side. I plugged the lines going to the manifolds, so the air pump is just pumping air under the hood, all the vacuum lines are still hooked up and functioning, There is just no air being pumped into the exhaust manifolds,
Weird thing is it seems to run better now than when it was all hooked up LOL,
