Some oil in the intake system is normal as it is carried over from the crankcase breather which filters out most of the oil in the crankcase vapors before they are routed to the intake. So no, your engine is not going bad based on that... depends on what you mean by "a lot" however and that can be subjective depending on who is observing it. The failed intake tube is a well known pattern failure. The crack and separate usually taking some time to do so. When boost air in the tube can leak out it throws off the entire air management and exhaust aftertreatment systems because the MAF sensor reading is no longer accurate. It is not uncommon for the DPF to clog when these fail slowly and I have changed a few for this very scenario however it is not always the case. I suggest that if the truck was driveable the filter is not actually clogged and can be effectively cleaned with a manual regen. But, if there is soot in the tailpipe it is bad... and at 54K replacing it only benefits you in the long run to be honest. As fo the fuel economy I think I normally see numbers like yours on customers trucks... some are indeed higher 14-16. Fuel economy is affected by many things as I am sure you are aware therefore difficult to determine if there is actually a problem or simply your diving habits, driving conditions and towing for example. Some fuel in the oil is also normal. Do you know the percentage? Once the CAC tube and DPF issue is corrected your fuel/oil numbers will likely come down a little since regeneration problems can affect that.
