A friend of mine wants me to replace the valve cover gaskets on the 3.3 v6. How bad of a job is it? The front looks like it will be easy to get to, the back looks like I will have to pull the intake manifold off of it for sure.

 

Removing the wiper tray will open up a lot of room to access the back of the engine.

See the following thread (post #5) for instructions: https://dodgeforum.com/forum/dodge-c...ml#post2928990

 

The front is easy as you said. The rear requires removal of the upper intake manifold to get at it.
It's not a bad job to do, just make sure you have new upper intake gasket ready.
