If the 1991 lumina's engine is the same as the corsica LT's, then location is pretty easy to find. In the back of the engine, located in the middle, a few inches down, should be a rubber hose about 3/4inches wide. This hose goes into a gromment in the valve covers. It should be easy to pull out by hand. At the end of the hose will be the pcv valve which should resemble a car cigarette lighter. Shake it. If it rattles then it should be okay to go. If it doesn't, then replace. Good luck. The following web address will lead you to an image of the engine and the area you will find the pcv valve in. http://img113.exs.cx/img113/182/pcv-valve.jpg
