What exactly are these "dirty and clean" PCV lines that are mentioned in some posts? I have a 2004 V8 awd and would this be something to be concerned about? Have 70K on it with minimal problems(knock on wood!) and like to keep on top of things. Thanx

Re: PCV lines
The dirty line goes from the PCV orifice to the intake manifold to evacuate crankcase gasses. The clean line goes from the air supply side to a valve cover to supply clean make up air for the PCV system. Both lines can get brittle and leak, usually causing a DTC.__________________________________________________ ________________
