I'm a very cold morning earlier this week, i had the truck running on auto start for a few mins. When i came out i could smell the exhaust a little stronger than normal. Didn't think much of it since it's freezing. I left and came back to find a puddle of what I think is soot. It resembled a very thick oil. Upon investigating under the hood I see what is pictured appearing to be leaking. Can somebody help me to identify what this is? Looks like it needs to be replaced. Is this the DPF? Thanks!
