If your truck was built after October 10, 2018 (I think, I know it was in October sometime) your engine already had the upgraded egr valve. Upgraded but still possibly defective. The pre-October egr valves just had the screws screwed in so some came out, the new ones had the screws welded. Now the issue seems to be the shaft can fracture. Go figure.Thanks for the knowledge..I looked on Ford Pass and it said 20E04, so Im assuming there was no 18E02 needed as my Ford Pass did not show it..Sometimes technology scares me..
