Yes, I think PCV was what was intended. I think Autocorrect happened.When you say pvc is that the pcv valve? Just for clarity.
Also any other maintenance done? What was whining? Like a power steering pump whine, radio hum/whine from alternator failing, maybe a tired belt or pulley?
If you replaced the pcv valve then there may be a vacuum leak like suggested. Get a bottle of $5 carb/choke cleaner and use the straw to apply it near vacuum lines, egr system, intake plenum and throttle body. If the rpm react to the spray investigate for a leak in that area.
