Headgasket Leak

Anyone have a hadgasket leak in their X. I have a 2002 and dropped it off at the dealership last night and low and behold...a head gasket leak. Not really sure what that all entails but thank goodness it's covered.

Recall maybe a couple, quite rare from what I've seen.

I've heard of coolant leaking into the engine as a recognized problem by Nissan, but not exactly a blown head gasket.

Only coolant-related problems I know of that are more than very rare are a leaking fast-idle cam, and a leak at the intake manifold water outlet (which has a TSB: http://www.nissan-techinfo.com/nissan/TSB/Augu/54050.asp)
