This is a 1993 SE. Having changed the water pump, upper & lower intake/plenum, throttle body and thermostat gaskets I have found coolant where the EGR "tube" ties into the block. It'* below the thermostat, but I can't feel any moisture on the upper hose etc.
Is common malady in this area that I have overlooked? :?:

The EGR doesn't tie into the block at any point, so we're either going to need a picture or a much better description of the location.

It is the tube (metal appx 1") from the bottom of egr that ties in with a single bolt retaining flange.

There is no coolant source there. The EGR mount bolts to the cylinder head. There is no coolant in the EGR itself.

You have to narrow it down. Gravity is your friend. Look up.
