I will get it out after I do the repair next weekend. If you have codes, the valves in the intake aren't working properly and likely causing more restriction on top of the buildup from the EGR and oil vapor. I have don't almost nothing but highway 150+ miles 4-5 days a week ( long sustained drives at temp) and minimal towing of the 111000 miles I have clocked so far. Based on other horror stories online of teardown pictures I fully expect to have intake ports that are was much as half plugged up. Based on the MAF numbers the computer is giving me, I expect mine to be mostly plugged.I’ll be looking for this write up. I’m running a diesel at 126K, and have been showing those codes for a little while. Still runs and still has power and great fuel milage, so I’ve been planning this as a post-season project.
At 1/3 throttle I can't get much passed half the air the computer is asking for. those numbers keep their spread at just about any throttle position. Plus I can't keep temps down at all no matter what I'm doing... cruising at 70deg ambient.... 224 water. Post egr and intake air temps are increasing too and the fact my EGR tube buildup is now dry... I have a hot intake from restriction. It's a time bomb that will destroy an eco diesel if not repaired. I will get a post up with documentation of the open chest surgery. I plan to do this next Friday. I think we all and JEEP need to see this shitbox we have been sold that they won't stand behind at all after selling us all on diesel longevity and fuel economy. Mass air flow discrepancy below...with 27 lbs of boost.. Not good at all.

I would have suggested the 3.6L but Im biased.
