is there ne way to tell if i bent a valve without taken the head off
cause i was driven last night and my car started to bog and go putt putt so i poped the hood and my 4th spark plug wire was off compeletey could it just be bad wires or maybe i bent a valve?

 

If your 4th plug wire conductor is right off, I would say it's just your wires that need to be replaced. Borrow that one wire, and test it. You can check for bent valves by performing a leak down test.
