Check ecm connections and bulkhead. A man with a pressure washer can do a lot of damage that may not pop up for months

Verify the egr valve is working properly as well as the VGT. Both can cause high intake temps.

No other codes, now that you say that I wonder if the VGT is unable to actuate to full open or close. The truck ran for about 2 months putting a gallon of coolant each day from a failed EGR cooler. Talk about gunked up sticky mess... I’ll keep ya posted
