ISB 6.7 Too Much Soot Guidance

[Craig]

Thanks so much for you input, I will have to take your response back and try and get the answers. Sounds like it's going to be expensive, however, they just bought a new truck and I think you may have saved it from the same fate as this one. I'm going up there this weekend so I'll get some answers and try to create a game plan to go through all the systems you mentioned. Or, after reading your response, he may just want to demandate it because of cost. I'm trying to get him to fix it for obvious reasons, yearly inspections and such but didn't really know where to start but now I think we have a jumping off point for sure, can't thank you guys enough :).
