from the picture, and not knowing what your pointing at.. I would say that is the HVAP purge Solenoid/valve.

Check with the Dealter for a replacement part for the PCV or you can try using other fitting and hoses to repair it. Maybe find one at the junk yards.

Yeah, the first one is the EVAP purge valve.

The second one, I can't tell for sure either. Looks like the PCV fitting in the drivers side valve cover? Mine's busted off, and looks kinda like that.

one end of the valve goes to the port on the Intake (driver side) and the other port on the vavle goes to the Fuel tank. When the PCM triggers the Soleniod, it purges the fumes from the tank.

Can't you just program out the evap system and delete all of the components?

YEs you can delete EVAP and the associated codes from the PCM. From my understanding, the EVAP solenoid works even if it isn't plugged into the PCM. When the fuel tank reaches a certain pressure, it purges the excess fumes. There was a thread somewhere on here discussing this.

The PCV system is to draw oil mist out of the engine, and help with ring seal a little bit, I guess.

I am going to add a catch can on mine once I get all my turbo pipes ran. With a regular engine, there are places that sell a little filter that can go there, or I suppose you could drill it, and tap it, and thread in a hose barb with a nipple the same size as that stock piece.
