When the my civic starts up there is a tapping noise coming from the valve cover area. After about one minute it goes away as the motor gets warmer. I heard this is normal for high mileage civics and I shouldn't worry about it but i would like to get another opinion. Also The tapping noise frequency matches the engine rpm.
