Where is the PCV valve for a 1990 LeSabre?

The elusive PCV valve does not leap out at you on the '90 LaSabre. Since, if your engine and it's spark plug wiring wiring is configured the same as mine, and hopefully it is for the sake of this answer, the PCV valve is hidden beneath those wires and, mostly, is further camouflaged by oil. Anyway, here's how you find the little sucker: As you stand next to your left tire, looking into the engine compartment, follow the 3 rear spark wires, from rear to front, ABOUT 3 inches PAST the REAR rocker arm cover. Pull the wires aside and look down a bit. There, at what might be called the south-west cornor of the rectangle engine block, if you consider the way you are facing to be "north", is the PCV valve. It's real close to the engine block. It fits stright down into its gromet with the hose the conects to the top/plactic part of the valve being only an inch long.
