I may be looking at this wrong then. At the passenger firewall the is what
I think is an expansion valve (rectangular block that the hoses connect to).
I also believe this contains the orifice tube that extends into the valve
and has a large diameter flat piece on the top of the valve.

You can't run both expansion valve/block and orifice tube...they're two
different systems that do the same thing. As for the auto-adjusting orifice
tube...i'd like to see that. The newer models ('05+) do have something like
this, but on your model, it's just a metal/plastic tube with a screen.
Just replace the orifice tube.

For a '93 318 there are 2 options for an orifice tube. One is $3.88 and the
other is an "automatic adjusting orifice tube for normal climates (105
degrees)" for $24.94.
What is an auto adjusting orifice tube?
These can be replaced without replacing the entire expansion block? My
friends '97 Caravan was a one piece block/tube.
In what case would I need to replace the expansion block too?
Thanks,
James
