davids,
It is normal to have a little corrosion/white powder buildup on the head gasket - my 2000 C115 has done it since brand new. For this, I just lightly spray the gasket with WD-40 and wipe down.
On the other hand, you could possibly have a couple of loose head bolts - if there is any question, take it back to the dealer since it is under warranty and show them your problem - they may retorque the head bolts.
Good luck,
