That 3.0 engine has a pretty common problem with worn valve guides and valve seals. If the guides are worn out, that pretty major surgery to repair that but you can replace the valve seals a little easier. Even that is a good size job to replace the seals but it will help, at least for a while on most vehicles. It's almost 6 hours labor to do both banks so your looking at a little over $500 plus parts.
