Nice dig on the plastic oil pan. I also have the 2017 with the plastic oil pan. I also had a 2011 F350 6.7 with the plastic oil pan and put 100k miles on that motor/engine with no oil pan issues. No issues at all to be frank. That includes about 20k miles towing a 31' toy hauler loaded to 15k - 20k# easy with sand rail and dirt bikes/quads. Lots of challenging roads like 9 mile road to Kennedy Meadows half a dozen times. 9 degree grade constant for 9 miles. No turn offs. Also no oil pan issues.
