valves don't knock...they tick
more then likely you got a spun bearing = rod knock.
Listen to the engine while somebody is reving it for you. Try to hear the engine by the oil pan/bottom of the block and that will give you an idea where the knock is comming from.

Re: motor is making a knock noise (Mr.RHTuner)
ok, but rod knock doesnt not happen at idle right? At a stand still it sounds normal. but yea it does sound like its coming from the bottom portion of the motor. Am i putting the motor at a danger if i drive it like this?

rod knock can happen at any RPM
-dont drive the car anymore as your just doing more and more damage
