These cars are famous for leaky seals where the valve cover interfaces with the cylinder head, at the spark plug journals. They fill with oil, short the coils and cause a misfire. Driving it any significant distance can destroy your catalytic converters ad unburnt fuel ignites therein, creating inferno-like conditions and a fire hazard too. You'll get a "300 code", such as 301 if cylinder 1 is misfiring, 302 for # 2, etc. Pull the coil off the spark plug for that cylinder and if it is moist at all, that's your issue. Have new seals put in, or you'll just keep blowing coils at $50 a whack.

Very common problem is about a dime size hole wearing in the rubber elbow on the PCV valve located on the driver side rear of the intake manifold.

The cooling fan on the LS-V8 is hydraulic yes. But it also has a pressure switch on the pump that drives the fan. It is controlled by the temperature sensor. All these things must be taken into account. But the whining sound my lead me to believe that the pump is either low on fluid or is wearing out. The fluid the fan pump uses is the same as the power steering pump container so check it first. The same thing happened to my wife's Lincoln. I replaced the fan as well because everybody told me to do that but it didn't work. I found out that the fan is just a hydraulic motor in reverse it only spins as fast as the pump makes it spin and that is controlled by the temp. sensors. When the engine get's hotter the pressure goes up and the fan spins faster. This adds more power to the engine when it's running cooler because the fan doesn't have to spin at max speed. So good luck. I hope this has solved your problem.
