+internal engine sounds are usually rythmic. get louder and quieter in a pattern.
+
+listen with broomhandle. 
+
+a clattering disorganized sound would be external -- AC, power steering, etc
+    take the belt off and start the motor
+scattered disorganized sound could also be torque converter, loose bolts, flex plate, etc (will go away in gear, come back in park/neutral)
+
+tapping sounds -- lifter noise, bad lifter, broken valve spring, rocker is shot. often changes with rpms (also possibly loose timing chain)
+ping noises down low can sound similar, cracked piston, excessive space between rod and piston
+to tell the difference, apply load, vary gas at steady speed, a piston noise will change do to the load, lifter will not. if noise goes away, let off the gas, if it gets louder again it's the piston.
