i agree...i think the piston slap wouldve been there always, not just develop one day. i know GM has the same issue with a lot of their truck engines...they slap when cold because of the piston skirts.

if you have a tick i would suggest getting a long screwdriver, and touching it to different areas of the engine with your ear on the other end...cover your other ear. if the noise isnt normal, when you get close to it, it will make itself very pronounced.
