ive never heard any piston slap in my engine. but i do have a noise up front at idle that kinda sounds like marbles moving around. im pretty sure that its caused from the oil pump not pumping enough oil at idle. its a timing rattle. other people on this site have the same issue and they have been hearing it for a long time so i wouldnt worry about it.

im just curious, are you having piston slap on yours? how many miles are on the engine?
