Broken manifold studs on my 4.7 PITA!!!!!

3.7's/4.7's are maintainence whores....fix the obvious things wrong with it and ditch it!

They like to also get gummed up oil passages to the cams/heads and kill timing cains with a vengence....they do make good power though. For a driver, I wouldnt use one, simply because of the required mechanical up-keep.
