Just for that, I'd treat myself to some Accufab goodies.

oil residue in Intake is somewhat normal with car equipped with EGR. That light brown color in throtlle plate is normal color to me as well.

I'm not sure about that ugly bump. Mine wasn't like that when I ported it. I have heard of there being a casting bump, but mine wasn't that bad. Maybe they fixed it somewhat through the years. Couldn't hurt to dremel that down through. While your at it you could go ahead and port it a little and polish the inside, that wouldn't cast anything if you have the dremel. If you don't have one and would have to guy one, No better time then then put that money into an Accufab.
