Default EGR cleaned, still faulty?

on my 2005 3500 I took out the EGR valve and cleaned it with Deep Creep. I spent an hour with a toothbrush but still it had a bit of black residue on it, and wouldn't close all the way by itself. It still ends up belching dark smoke, but usually only after an hour or so of driving. I also had an O2 sensor replaced, which I fear may be fouled again.
Wondering if I should just buy a new EGR, or if there is something else to do?
