A: Westco Automotive regularly services all three "Big 3" diesel platforms across their most common engine generations—Ford Power Stroke (6.7L, 6.4L, 6.0L, 7.3L), Cummins (5.9L and 6.7L), and Duramax (3.0L and 6.6L). Across all these engines, the most common diesel repairs and services include: Fuel system service – diesel fuel filter replacements, injector diagnostics/replacement, high-pressure fuel pump repairs, and water separator maintenance Engine diagnostics and repair – check engine light diagnosis, loss of power complaints, hard starting in cold weather, excessive exhaust smoke (black, white, or blue), and blow-by/crankcase pressure issues Routine preventive maintenance – oil changes using diesel-specific oil, battery and electrical system checks, fuel filter changes, and comprehensive vehicle inspections Ford Power Stroke Engines 6.7L Power Stroke (2011-present): CP4 fuel pump failure – The high-pressure fuel pump can self-destruct, sending metal debris throughout the entire fuel system, often requiring replacement of the pump, all injectors, fuel rails, and lines (a $10,000+ repair). Disaster Prevention Kits (DPK) are available to contain damage . Crank/no-start conditions – Often related to fuel pressure issues; requires monitoring of desired vs. actual rail pressure during cranking; P0016 code (crankshaft/camshaft correlation) is a common diagnostic challenge . Cold side intercooler pipe failure – Known failure point that can leave you stranded; the pipe can blow off under hard acceleration . 6.4L Power Stroke (2008-2010): Radiator and cooling system failures – Radiators are a common failure ($1,100+ installed); leaking radiator hoses cause low coolant, leading to cavitated front covers (coolant in engine oil) and failed EGR coolers . Excessive crankcase pressure (blow-by) – Fuel and moisture forced past piston rings; often caused by sticking piston rings; can be diagnosed by placing the oil fill cap upside down on the hole – if it blows off, blow-by is excessive . Catastrophic engine failure – Many 6.4L engines don't make it past 150,000 miles; complete engine replacements often run near $20,000; common failures include lifter failure, cracked pistons, and cracked heads . DPF/EGR system issues – The emissions systems cause most of the havoc; many owners choose to delete these systems (where legal), but Westco can diagnose and repair factory components . 6.0L Power Stroke (2003-2007): Head gasket failures – Factory torque-to-yield head bolts stretch under high boost; upgraded ARP head studs are the standard fix. Oil cooler clogging – Coolant contamination (often from casting sand left in the block) clogs the oil cooler, leading to EGR cooler failure and white smoke. High-pressure oil system (HPOS) issues – Failed STC (Snap-to-Connect) fittings on 2004-2007 models, clogged HPOP screens, and standpipe/dummy plug leaks cause crank/no-start conditions. FICM (Fuel Injection Control Module) failure – Low voltage or logic board failure causes rough running or no-start. 7.3L Power Stroke (1994-2003): Injector Driver Module (IDM) failures – Code P1316 indicates IDM or wiring issues; can be caused by faulty IDM relay, poor electrical connections, or injector harness shorts . Fuel bowl leaks – The yellow fuel bowl drain valve is a common leak point (approximately $80 repair) . Hard start/no-start conditions – Often related to fuel system issues or IDM/PCM communication problems . Cummins Engines 5.9L Cummins (Common Rail, 2003-2007): Injector return line issues – Excess return flow from failed injector solenoids prevents rail from building pressure; a hung-open injector return can cause sudden engine shutdown; capping return lines individually helps identify the problem cylinder . CP3 high-pressure fuel pump – Generally reliable, but can develop internal issues; debris contamination is the primary concern . ECM and wiring issues – Wiring inspection and pin checks at the ECM connector are common diagnostic procedures . 6.7L Cummins (2007-present): EGR system carbon buildup – Carbon sticking in the EGR valve and cooler is common; requires cleaning or replacement . Variable Geometry Turbo (VGT) issues – The variable nozzle turbo can stick due to soot buildup; actuator testing and cleaning are common repairs . After-treatment system (DPF/DOC) – Regeneration strategies and diesel particulate filter cleaning or replacement are common on higher-mileage trucks . Both 5.9L and 6.7L Cummins: Common rail injection system diagnosis – Low pressure system checks, return system testing, and injector balance testing . Cooling system issues – Coolant consumption requires specific refill procedures and testing . Duramax Engines 3.0L Duramax (LM2/LZ0, 2019-present): Westco Automotive has documented experience with the 3.0L Duramax diesel engine found in vehicles like the Chevrolet Tahoe. Common services include check engine light diagnostics, preventive maintenance, and fuel system work. 6.6L Duramax (Multiple generations: LB7, LLY, LBZ, LMM, LML, L5P): Thermostat replacement – A common maintenance item on the 6.6L; involves draining coolant, removing the alternator, and accessing the thermostat housing . Injector failure (LB7) – Early LB7 engines (2001-2004) are known for injector failures requiring replacement. Head gasket issues (LLY/LBZ) – Similar to Ford 6.0L, head gaskets can fail under high boost; ARP head studs are the common upgrade. CP4 pump failure (LML, 2011-2016) – Like the Ford 6.7L, the CP4 high-pressure fuel pump can fail catastrophically, taking out the entire fuel system. Summary Westco Automotive is equipped to handle all these diesel platforms as a trusted, fairly priced alternative to dealerships. They are known for tackling complex issues that other shops may overlook and providing transparent diagnostics with multiple repair options . Regular preventive maintenance—including fuel filter changes at every other oil change, water separator draining, and quality fuel additives for lubrication—can significantly extend the life of any diesel engine .
