  • Knocking Noises

    Hey everyone,
    Got a question ... I have a '99 Camaro. When I start it up in the morning I hear a slight knocking sound while the engine is still cold. Once it warms up the noise goes away. Any ideas as to what the knocking is and is it a big deal?

    I Have no idea but mine is a 99 and it does the exact same thing... I remember a Chevy tech told me that these engines have a lot of piston slap... makes me feel safe running NOS
