SCR weep hole?

2013 CXU with SCR. Noticed what appeared to be exhaust pulsations leaking out of the SCR under the mounting strap along with a trail of soot while regening. Dealer says this is normal to see from a weep hole which is apparently intended to drain condensate from between the inner and outer shell of the SCR? But with a trail of soot? Thanks in advance for any comments.

I have seen steam from water collected in the system coming out from under the front mounting strap before, usually disappears after a couple of minutes. First started noticing this in 2013 trucks. There should not be any soot coming from there though, indicates a problem with the filter or excess smoke being exhausted from the engine.
