Rattle

Hi, I've got a 2001 Z24 with the 2.4L (duh!), it has 99,000 kms or 61,000 miles roughly. In the mornings (usually), or if the car has sat for a while, I get a rattle for about 1-2 seconds upon startup. Does anyone know if this is normal for this engine or should I have a dealer look at it before the powertrain warranty expires next month. Anyone who can help be would be doing me a hugh favor, especially if I can get some engine repair work for free.


Thanx in advance.
