Noise on Startup

When you say "enhance the noise" do you mean it'll be louder or quieter?

I have the same issue as the thread starter, engine makes about 3-5 taps from the engine like a dry lifter or valve and then is quiet... if i imediatly turn the engine off and then restart it the noise will not come back again until the engine has been sitting for more than 2 or 3 hours.
