gasket leaks, piston slap, sierra 4x4: If there was coolant in the oil it would be visible on the dipstick, the fact that the noise goes away indicates to me that it is something like piston slap, which, once the piston heats up and expands goes away.

intake manifold gasket, chevy engine, timeing: I would start with the timing. The noise you are hearing is likely spark knock or detonation. Not good for things.
