If the vehicle is subject to nothing more than just short trips, then this would be normal. It would also cause accelerated engine wear due to corrosion. What you are seeing is condensation mixed with some of the oil/residues inside the engine. Remove the oil cap, and the underside should be just covered with the same. Take the car for a run of about ten miles, and check the condition again, while the engine is still warm. If the condition remains the same, you may have bad intake, or head gasket(s).

Why does the engine light keep coming on indicating EGR valve in a 2000 Chevy impala after the EGR valve was replaced?

I just replaced my egr valve and my light went off, however some reasons for yours not to go off might be that the hose/pipe coming out to the eghaust manifold into the egr valve has enough deposits in it to cause a blockage.....signifying that your old egr valve was good, just not getting any unburned fuel to it. I don't know how to clean the blockage out so maybe search the net and see if you can find out how to do that. perhaps a carborator cleaner will work?
