The EGR valve is located in the center of the intake, at the front of the engine, between the alternator and the A/C compressor. I've added a picture of the location to the links on the right. It is titled "Picture of EGR valve location, on 1996 - 2001 4.3L (262c.i.) Vortec V6 engines"
It is right beside the thermostat housing, and that is where the top radiator hose hooks to the engine.
2003 4.3's do not have an egr valve.
Thank You
I am trying to find out if this is the correct t-case for my 98 jimmy 4l60e/4.7 vortec
You can find the PCV valve for your 1997 Mitsubishi Montero on top of the engine. The PCV valve will be in front of the air cleaner housing.
On the valve cover, with a large vacuum hose attached

Most major auto part stores will stock the standard EGR valve for a Vortec 4.3-liter engine. You may have to visit several to find one that has it.
It is inserted into the passenger side valve cover. It has a "thumb sized" rubber hose connected to it.
vacuum hose from window washer to where it runs from small hoses running under the window
It is just below the lower radiator hose.
If I'm not mistaken, it does not have a pcv valve, my 2000 doesn't have one on it...
