I suppose next week while the EGR valve is off I could start her up and see if exhaust comes out of that port.

Also, I didn't even think to look, is it possible that the intake plenum is clogged up? Does it have any internal plumbing in it for EGR? I thought it was just basically a hole in the plenum so very little chance of clogging. I guess I should look into that before I order a new valve...
