CM2250 Leaking doser

[fargonaz]

I have an old Gordon truck 2012. It seems to be fairly well kept.
Goes through 0.75 gal of oil in 16K. Power seems fine considering it is a 369/922 tune according to quickserve.

I can't remember the code I got, about 6K ago, but when I researched it, it is was for the DPF. It stayed lit for about 1.2K and then was gone(around Thanksgiving.) Have noticed in the last 2 weeks (because fan clutch is acting up) that the doser elbow is wet stained with fuel at both ends and I get the associated kerosene/hot fuel smell and cloud until it is at operating temp.

So the question is: Any long term damaging effects from this, planning on replacing it the middle of this month when I get the annual done.

Thanks
