Weird grinding noise after cold start??

Hey guys. I have a 2005 AT with about 1000 miles. I have been getting a weird grinding noise (only for about 1 second) everytime I hit the accelerator for the first time after a cold start. It only happens on that first touch of the accelerator. Runs fine after that. Its been there since I got the car last month. Anyone have any ideas on this before I take it to Infiniti? TIA

Jason

One of our members who works at Nissan/Infiniti (JustBrilliantX) explained that the chain sticks to the chain tension (front of engine) and until it gets some lubrication, it rattles mementarilly.
All of my VQ's have done this especially when cold.
