What does a PVC do and what does it stand for and where does it go in an engine?

Well, keep in mind I'm not a mechanic. I think you mean a PCV valve, not a PVC valve. PCV stands for Positive Crankcase Ventilation. A system using a PCV valve evacuates gases from an engine's crankcase, and I believe they always go on top of the crankcase. It's purpose is for fuel economy and the environment.

Where is the PCV valve located on a 1989 Park Avenue?

On my 1994 with a 3.8liter. i found it by popping the plastic shield off the area above the fuel injectors. saw a vertical stand pipe with a plastic cap. tiny letters "pcv" on it. removed the cap by giving it a 1/8 turn with a 3/8in drive. carefully, look to see which way it goes. you can just see the top of the pcv down in the pipe. needle nose to get it out. carefully note the o-rings on the old one. may need to use one of them on the new pcv.
