i've gone to Napa and Canadian Tire and they can't even come up with a part number in their computers for an EGR valve for my car... i'm somewhat sure i have one as i can see this square box with a vacuum hose leading up to a port on the intake manifold...

it's a 1991 civic DX 4-door with the auto tranny if it makes a difference.. it has the dual point injection.

Mines a 91 LX 5spd with the same motor and not equipped with an EGR system..

 

I don't think they had EGR valves. But i'm not 100% sure about that. Lets see a picture of your square box.

 

i don't have a camera available to me right now :\

someone else HAS to have this thing on their engine :D

between the 2nd and 3rd port coming from the fuel injection/throttle crap leading into the engine, there's an additional port that ends, then a vacuum hose is attached to the top of it. it leads downwards to this box thing (it's connected to the right side of the box thing if you're standing in front of the car). the box thing seems to be attached with just one bolt that attaches via a bracket that seems to reach around an intake pipe of some sort...

that intake pipe also has a hose attached to it that leads up, is tied together with another hose, and then ends at the air intake.

the box thing is directly above the oil filter.
