100k is pretty normal but the oil in the rad may be a damaged radiator if it has an internal oil cooler

GM has had a problem with the pink (or orange) antifreeze. It eats away at gaskets, then turns to a muddy colored gunk. I've had the same problem and my mechanic has switched to the green antifreeze. It takes some work to get the old stuff out. I've had the engine flushed 3 times in 3 years.
