Are they forged pistons? if so its probably piston slap, nothing to worry about, I belive its the piston inside the bore, where its not up to temp its smaller than the bore and theres movement as they heat up and expand, they fit, I think thats right anyway.

forged pistons are known to be noisy in our cars.....this is a bit natural......some even complain the car sounds like a diesel when the engine is cold
that's why its critical to get the clearances within manufacturer's range when fiting these pistons....so that it minimises any ill effects---noise, oil seepage, seizure from expansion, etc.
