   * From piston to head impact:
     * Can be caused by worn/damaged rod bearings or flywheels out of true.
     * Can be caused from improper installation. \\ Using a flywheel assembly from a previously destroyed engine without inspecting rod bearings and runout. \\ Always rotate the crank while the jugs are off and check for smooth feel and check up and down play in the rods. \\ It helps to have a quiet atmosphere. Dump oil on the bearings and listen all the way around in neutral. \\ Then spin it over by hand in before buttoning up. You can check the squish band dim with solder.
-    * Also, if the squish band has a layer of soot thick enough to touch the piston, it'll make piston slap noises. ((norseXL of the XLFORUM http://xlforum.net/forums/showthread.php?t=1575186&highlight=stethoscope&page=2))
