[QUOTE="Maryland dieselnick, post: 1272592, member: 22661"] First, I'm not saying it's rampant but there are trucks including 16s doing it. Ford needs EPA approval for PCM changes. One is supposedly going to be tried in the second quarter of 2016. These trucks have the same strategies. Some are fine in this condition dept. goes while others do not. Once the head is on the bench with the springs removed, the true root cause is revealed. A quality control defect, guide stem clearances too tight and every truck and or guides are just a bit different manifesting itself at different miles. Some do it regen number one and the clearance on the bench at room temp is way too tight, let alone at high temps. There engineers are even saying they are not sure a new calibration will take care of it. This is because some are tighter than others. [/QUOTE]
