Using oil and has a vacuum suction during idle where I add oil.

5.2 V-8

It aint breathing, pcv is working great but the engine breather not so good! Tat is all i got.

Had my uncle, that used to rebuild engines, take a look at it as I was stumped. He immediately noticed the vacuum, and showed me suction associated with the air filter on top as well. He did say the pcv was not bad, but told me intake manifold gasket was prob blown. I've never owed a Dodge, so didn't know anything about them, I was just in awe when I saw the immaculate condition of the truck, and didn't ask questions. It did, however, loose oil pressure going up a hill last week, thought that might have been when the gasket blew.
