It's under the alternator. The grommet that it sits in will probably be hard as a rock, so get one of those too. Not an easy job as the alternator has to be removed.

I NEED to replace the pcv value in my 1991 buick century custom 3.3 engine car. how do i do that


Ok when you're looking at your engine look at the valve cover with a black rubber hose with a funny plastic piece which fits into a rubber grommet in the valve cover. This is the pcv positive crankcase ventilation valve. Remove the pcv from hose after you've obtained a replacement throw it away insert it into the hose then the valve cover and you're good to go
