Oily egr tube and map sensor

I keep pulling 2 codes on a regular basis, p24ae and p2459. After doing a forced regen they both come back within a few days. I finally pulled the egr tube and the map sensor and both were really oily instead of having the gummy build up I've seen in all the YouTube videos.

I also have a problem where if I'm doing a lot of city driving my exhaust will start to smoke heavily of and on. It will smoke the same way it does while doing a regen. I attached a pic for reference.

Truck isn't burning through coolant and doesn't appear to by burning through oil either. Am I having an oil blow by problem, or maybe something else?

Doesn't seem right but I don't have an answer. Maybe TC will see and chime in.

I forgot to mention, only the intake side of the egr tube was oily, the egr side was a lot drier and fairly clean
