What is a blown seal?
On rear wheel drive engines, the oil pan at the bottom of the engine does not completely connect to the block. It has to make room for the crankshaft at the front and the drive shaft/crankshaft at the rear. this is a half circle design in the oil pan to match the same design at the bottom of the block. In order to keep your oil in the system, there is a gasket that is either heavy cork or rubber that conforms to the shapes of the pan and block while at the same time it is wrapped around the crankshaft. When either the front or rear "main seal" "blows", it is simply worn too thin to prevent the oil from leaking out. The same theory applie to front wheel drive engines.

I am assuming that you mean the main seal on the crankshaft. Generally replacing the main seal requires that the crankshaft be removed. Which usually means the engine has to come out. I don't know anything about the 3.0l engine. Any of the vehicles that I owned that had a main seal leak never got changed.
