I am trying to figure out if the 2004 is prone to the cracking issues that plagued the earlier 4.6's. Some days it is fine, other days it leaks like a holey bucket. Would pulling the intake and replacing the -o rings help?

Thanks!

My 04 cracked leaked too. I located my leak right behind and underneath the thermostat housing. Never heard of an intake leaking that wasn't broken but it is best to try and locate the actual source of the leak prior to going all in on an intake swap. If you pull the intake you will ultimately find the source but I haven't heard of anyone just replacing the gaskets and fixing the issue.
 
You need to find the source of the leak. If you have a cracked manifold it's and easy replacement project. Several write-up here as well as Chiltons or Haynes manual would get you through it.
