The last two parked regens, I had black/blue smoke rolling off the top and side of the filter box. And into the cab thru the air vents. Any idea where to start addressing this issue?
First on was in Tn. And it melted the plastic that was covering it. It melted on the box like hanging icycles. I removed that area thinking the heat cossed it to melt. And land on the filter box. But it smoked again even when the plastic was not there.
That is all I know as of now.
