Yeah ... it's insane. That was the video I actually watched to figure out where the hell it was after 20 minutes of looking. My girl hit 30,000 miles so I wanted to get it changed out.
Tried to see if I could get to it from underneath the car, and no dice. Manifold has to be removed.
Unlike that guy though, I'll most likely unbolt the throttle body from the manifold (so I don't have to drain the coolant nor worry about flexing the lines too much).
I'm curious if Toyota increased the interval considering that it is positioned in a manner where, theoretically, it should suck up less oil and crud that will cause it to fail in the first place.
