Go to Pepboys/Autozone and buy a Haynes repair manual. They come in handy for jobs like this.

As already stated, get a Haynes - the PCV valve is right on top of the rear valve cover (towards the drivers side of the valve cover).

The EGR system difficult to explain via text. Do you have any EGR codes?
