Any other complications etc.?

Also have a valve cover gasket that is leaking... is that also a simple job?

By simple I mean like a 1hr job on the clock. Also, why do these leaks occur? Is it just lifespan of the part (temps/exposure), or is it possible that a small animal got to it. I ask because a squirrel had previously caused gas leaks on this car. It had been crawling through it for many weeks, but that was months ago.
