I wouldn't waste my time putting it back in all the time, after all there are two small drain holes for condensation relief in my DOC and the "after can" that is "in" from the DPF and "out" via the stacks.
If the OEM can do it, why can't I?
Better point, prove I did it and not the OEM.
I understand Waterloo's concern after already having a bad CO hit, but check your DPF housing, it may have the same 2 small holes mine has. I don't think a hole that small would be a major CO concern.
This is why I have a smoke and CO alarm in my truck.
