Platform recipes (5)

• Aftertreatment repair for the 2011-2022 6.7 (modes fm-ps67-def-system / fm-ps67-dpf-clog): sensors lie first - verify the DPS and EGT sensors before any assembly spend
• Full repair path after a confirmed CP4.2 high-pressure pump contamination event (fm-ps67-cp4-fuel-pump): metal debris in the fuel filter means the pump, injectors, rails, and lines are all contaminated, not just the pump
• Preventive measures against the CP4.2 contamination cascade (fm-ps67-cp4-fuel-pump) and the separately-documented plastic fuel-filter-housing cracking issue (fm-ps67-fuel-delivery) - cheap insurance against the platform's single costliest failure mode, applicable across all three generations since the CP4.2 pump has been used throughout (an aftermarket parts maker's 6.7L Power Stroke guide, a parts retailer's 6.7L Power Stroke guide)
• EGR repair by generation (modes fm-ps67-egr-valve / fm-ps67-egr-cooler): the 6.7's EGR hardware is generation- AND frame-split
• Turbocharger repair for fm-ps67-vgt-turbo - and the platform's clearest illustration of why generation matters: gen1 (2011-2014, Garrett GT32 ceramic-bearing) and gen3 (2020-22, per Ford's own catalog note) use ENTIRELY DIFFERENT turbocharger assembly part numbers (BC3Z-6K682-A/C vs LC3Z-6K682-A) - ordering the wrong one is not a simple supersession mistake, it is the wrong physical part
