If it is intermittent it could be your not putting the right octane gasoline in the engine. Normally this will make it ping under load. If it has a clatter from the top of the engine all of the time you probably need to adjust your lifters. This is normally not a problem for today's lifters. Also if the noise is from the bottom of the engine you probably have worn bearings. Hope this helps.
