Questions after changing air cleaner bracket.

[Biodiesel300TD]

Two things came up while I had the air cleaner off to change the broken air cleaner braket today.
1. The line in the two photos below very easly wiggles back and fourth quite and bit. The photos show how much it moves. The lines connects to a nipple on the bottom of the air cleaner housing, and the line appears to go down to the oil pan. Is is supposed to move like that? And, what is this line?


2. I had to loosen the hard line that goes into the turbo to get the old braket out and the new bracket in. Does breaking the seal on this line cause any probems? Hopefullly not. The line is the one dead center in the photo below.


Cheers,
Andrew
