2022 Ford F-350 Super Duty Chassis Cab
Reliability tier: verified - see /disclosure/
Engine: 6.7L (Power Stroke, 6.7L)
gen3 - 330hp/825-950lb-ft (825 2020-2022, 950 2023+ per our editorial notes) - no High-Output option on chassis cab
Applicable failure modes (11)
- Dual-circuit cooling system leaks (radiator / crossover tube / degas bottle / water pump)
- CP4.2 high-pressure fuel pump contamination cascade
- DEF / SCR / NOx sensor faults
- DPF clogging / regeneration problems
- EGR cooler thermal-fatigue coolant leak
- EGR valve soot clogging / sticking
- Low-pressure fuel supply weakness (lift pump, filters, water-in-fuel)
- Glow plug wear and cold-start faults, plus an isolated 2011-2013 tip-separation defect
- Piezo injector wear and fuel dilution of engine oil
- Intercooler condensation ingestion + cold-side charge-pipe fatigue
- VGT turbocharger failure - generation dependent (ceramic-bearing GT32 vs journal-bearing GT37+)
Applicable parts (10)
- Banks Power Boost Tube System, hot and cold side (2017-2026 6.7L Power Stroke, standard output)

- 6.7L Power Stroke CP4-to-DCR Pump Conversion (S&S Diesel Motorsport)
- 6.7L Power Stroke CP4 Disaster Prevention Bypass Kit, Gen2.1 (S&S Diesel Motorsport)
- 6.7L Power Stroke LPK/DPK Replacement Filter Kit (S&S Diesel Motorsport)
- 6.7L Power Stroke Turbocharger Assembly, gen3 (2020-22), Chassis Cab
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
