Considering you have just 4 days I would not go to the city of Puerto Montt and, clearly, choose some of the options I gave you.
I second this, it is a Flyertalk firm favourite. Get a rental car from Pueto Montt airport, drive to Puerto Varas. Next day drive to Petrohue, drive up Volcán Osorno, have a hot chocolate. Drive back down, have a leisurely driver around Lago Llanquihue until you reach Frutillar, have tea and cake, drive back to Puerto Varas
That leaves you 2 spare days, I would honestly be inclined to stay in Puerto Varas, maybe a drive along the coast a bit.
Ancud on Chiloe is a place where I have had happy times, to really push it you can probably make it to Valdivia for a night but Ruta 5 tolls are not as cheap as they used to be. I love Valdivia, a trip to Niebla is a favourite, a boat ride around the rivers, a trip to the Kunstmann brewery, decent restaurants. According to Google Maps, Ancud is about the same time-wise as Valdivia, I would probably pick the latter.
