From what I understand it should be dry where the valve goes. I would call it moist not wet but fairly moist. The top groove had the most wetness, the middle groove was dry and the bottom was nearly dry. Where do I go from here - the video I watched said to scrape out and vacuum - not dry enough.
You can get oily solids from the ccv system and even have a little un-burned fuel in the intake that does the same thing. It is different than actually having water/coolant in the intake.

I had the same issue with my 2006, I ended up doing a egr cooler delete, while there I cleaned my valve and had the intake hot tanked at a radiator shop. Now clean as a whistle.
That stuff was like Tar in mine
So you still have your valve with no cooler? If I put in the new valve will it clear out the code? (404/405)
On another note I bought a scan guage II thinking it would be a significant monitor of my engine - first glance makes it seem like MPG device - what am I missing
Did you buy a ScangaugeII ?? There are several models of scangauge.
If you have liquid under the EGR valve, it is most likely an EGR cooler leak and has nothing to do with the EGR valve itself. The P0405 is an electrical code for the EGR valve and has nothing to do with the potential of an EGR cooler leak.

To do the test you described above do I use the old valve or go ahead and install the new one? Question due to the fact I will have to pull it after parking downhill.
Installing a new valve - Will that get rid of the 404/405 codes?
Leave the old EGR valve in until you have driven it and parked it in a downhill position. Pull the old valve and inspect the intake.
Install the new valve.
The P0405 is from a bad EGR valve. A new one (assuming it is working) should clear that code. It is POSSIBLE that a P0405 might come from a bad connector, so inspect that carefully.
A P0404 is a flow code and can come from several causes. That one may or may not come back - depending on whether or not you have other issues.
