Recipes

EGR system repair for a 6.7 Cummins with a failed valve and/or cooler (modes fm-c67-egr-valve / fm-c67-egr-cooler: soot-clogged valve, coolant-loss cooler)
Fuel-supply health for a 6.7 Cummins on the CP3 common-rail (mode fm-c67-fuel-delivery): filter discipline, a healthy lift pump and a fresh FCA are what keep a $3-4k injection system alive
Grid heater bolt fix for a 6.7 Cummins (mode fm-c67-grid-heater-bolt): the intake-grid heater fasteners corrode/shear in the aluminum manifold, causing cold-start smoke, hard starts and an air leak
VGT turbo replacement for a 6.7 Cummins with sticking/failing variable-geometry turbo (mode fm-c67-vgt-turbo: VGT stick from soot, unison-ring wear, actuator faults)
