Does a 1999 Acura CL have a power steering O Ring?? on 1999 Acura CL

My car power steering fluid has air bubbles when you turn the wheels in the reservoir. It whines and worst in the am when its cold in the morning. A repair guy said it is a pump check valve? I have done some research and saw it may be a O ring? Any advice?

There are a couple different O-rings. I don't see a part listing for a pump check valve. Depending on what is actually leaking will determine what parts will be recommended for replacment. If something on the pump is leaking, you may need to replace the entire p/s pump.
