Adrian,

The photo you should look at is http://www.gmcmhphotos.com/photos/455-oil-pan-capacity/p10800.html
which more accurately shows the relationship of the various parts (disregard the un-trimmed dipstick tube).

There, you'll see that the two rods just right of the dipstick tube are near the bottom of their strokes and that they're at least 4" below the pan flange. In other works, they swing to within less than 3/8" from the 3 q. oil pool. If there's 4 q. in the deep end of the pan, the rods will definitely be submerged.

I apologize to everyone for having not anticipated all these factors when I originally made and posted the photos -- I could have made them more clearly and less ambiguously display the parameters of interest.
