Its hard to say for sure .But the most likely thing would be a lifter sticking .It rides on the cam shaft and the push rod sits on top of it and in turn pushse the rocker arm up and thatopens the valve. The lifter is filled with oil but also has a spring inside of it .If the spring hangs up when the engine is cold you will hear a knocking noise until the engine warms up and things expand. It may go away on its owen but make sure you change the oil regulary dirty oil cause this
