Yep, check your EGR cooler, it may have failed/ruptured.
Park the truck facing down hill or jack up the rear, as long as the nose is lower than the rear. Let motor cool down, then remove EGR valve. Look at valve and inside the intake hole, look for coolant/moisture. If you find it wet inside, the EGR cooler has failed.
Which could also mean that your oil cooler is blocked up. Have you checked your ECT/EOT delta?
