I deleted my washer fluid just now. I'm going to take a look at the TB coolant thing, but I may need to just button it up and make a parts run for that first.
Anyways, two other incidental things while I have the car in pieces. One, for those who were wondering about the closed-off ducts in the fangs of the front bumper, here's a pic from inside the bumper when the bumper is off the car:
Also, I had started the car up for a few minutes on the ramps and then shut it back down, and I started inspecting the exhaust. Turns out the big center flange (near the crossmember we had clearance issues with) has a bad gasket. The condensation in the exhaust system was leaking out from the bottom of the flange, that's how I noticed. When I went back and felt it cold, you can tell there's a chunk missing from the bottom of the gasket's edge. Hopefully replacing this gasket will solve some of my rasp issue, but I'll need to find an appropriate replacement first.
It probably got torn up from having that flange loosened and retightened (and the general area beaten and heated) many times over the course of a week or so while I was getting the crossmember clearance thing sorted out. Makes me suspicious of the other gaskets forward of this too, as they were also loosened and re-tightened multiple times.
