I guess intake manifold/gasket. No idea really, but that's my guess.

Isn't this problem usually the reverse? Water in Oil? Never heard of oil in the water. Check your oil too just to verify.

sounds like a head gasket issue. and yes this does happen from time to time instead of water in the oil.I really doubt its an intake leak.

Guy's, don't forget that the sport LS's have an oil to water cooler at the oil filter. I'd look there first since it is an area where the oil pressure would be higher than the water pressure, so the oil would go into the water and not the other way. It looks like an easy part to remove.

I haven't heard of any head gasket failures on the V8.

Are you sure it is oil? It could be rust,

Yes, if he's never flushed the coolant (should have done it twice by now, at least), then it could just be very dirty.
