If it ain't broken, don't fix it.
Generally you should separate db and app servers.. but if the machine can handle the load why not.. As for network issues, you should be able to derive from db how much data is send in/out and see if you can accomodate such demands.

Separating the two would also help figuring out where the problems are (if any) especially if both db and app use the same disks.

You're also underutilizing your Oracle licenes, or you bought too many.
