Introduction: Finding a Used 6.7 Cummins Engine for Sale
The 6.7-liter Cummins diesel engine represents the pinnacle of modern heavy-duty truck power. Since 2007, this legendary inline-six diesel has powered Ram 2500 and 3500 trucks through millions of miles of towing, hauling, and serious work throughout America. Known for exceptional torque, impressive longevity, and proven reliability, the 6.7 Cummins remains the gold standard among diesel truck enthusiasts.
But even Cummins’ legendary durability eventually faces high mileage, emissions system issues, or catastrophic failures. When your Ram diesel needs engine replacement, you’re confronted with staggering costs. Dealerships quote $12,000 to $18,000 for new engines plus installation. Remanufactured options run $8,000 to $14,000. Both figures often exceed your truck’s current value.
At 603 Auto Salvage in New Hampshire, we specialize in quality used 6.7 Cummins engines for sale at prices that make keeping your heavy-duty truck working practical. Our typical pricing ranges from $4,500 to $9,500 for tested diesel motors pulled from accident vehicles and low-mileage donor Ram trucks. You can browse our shop or contact us for current inventory.
The 6.7 Cummins evolved through multiple generations with important improvements:
Understanding which generation your truck uses determines compatibility, emissions compliance, and performance expectations. At 603 Auto Salvage, we identify engines precisely through VIN decoding and casting number verification.
Let’s examine actual costs for 6.7 Cummins engine replacement across different sources:
| Source | Price Range | Shipping | Warranty | Availability |
|---|---|---|---|---|
| Ram Dealership (New) | $12,000–$18,000 | Included | 3 years | Order: 4–8 weeks |
| Remanufactured | $8,000–$14,000 | $400–$800 | 1–3 years | Order: 2–6 weeks |
| National Online Retailers | $6,500–$12,000 | $500–$1,000 | 30–90 days | Varies widely |
| Local Salvage Yard | $4,500–$9,500 | Pickup only | 30–90 days | Limited |
At 603 Auto Salvage, our 6.7 Cummins engines typically fall into these price ranges:
These prices represent complete engines with turbochargers, high-pressure fuel systems, accessories, sensors, and wiring harnesses when available. Note: Higher mileage is more acceptable on diesel engines due to exceptional durability. For today’s availability in New England, contact us.
Understanding typical failure patterns helps you recognize when replacement makes sense:
DPF (Diesel Particulate Filter) clogs, DEF system failures, and EGR valve issues plague 6.7 Cummins engines. While these are emissions components rather than core engine failures, extensive damage from neglected emissions issues can necessitate engine replacement. Symptoms include loss of power, warning lights, and limp mode operation.
VGT turbochargers fail from carbon buildup, actuator problems, or bearing wear. Symptoms include smoke, loss of power, turbo whine, or oil leaks. Turbo replacement alone costs $2,500–$4,500. When combined with other issues, complete engine replacement becomes economical.
High-pressure fuel injection pumps fail causing hard starting, rough running, or no-start conditions. Failed CP3 pumps send metal debris through the fuel system potentially damaging injectors and fuel rails. Contaminated fuel systems often justify complete engine replacement versus extensive component replacement.
Fuel injectors fail from wear, contamination, or electrical issues. Failed injectors cause rough running, smoke, poor fuel economy, and potential engine damage from fuel washing cylinder walls. Six injector replacements cost $2,000–$4,000 depending on parts quality.
While less common than gasoline engines, overheating or over-boost situations cause head gasket failures. Symptoms include coolant loss, white smoke, and mixing of oil and coolant. Head gasket replacement on diesel engines costs $2,500–$4,500 due to labor intensity.
Some early 6.7 engines experienced crankshaft failures from manufacturing issues or extreme use. This requires complete engine replacement. Later generations resolved these issues.
EGR coolers crack causing coolant loss into exhaust or intake systems. Replacement costs $800–$1,800. Often accompanies other high-mileage issues making replacement practical.
When repair costs approach $5,000–$8,000, installing a quality used 6.7 Cummins engine often provides better value, especially for trucks exceeding 300,000 miles where multiple systems show wear.
When shopping for used 6.7 Cummins engines for sale, evaluate these critical factors:
Request odometer photos from donor vehicles. Check title documentation. Diesel trucks often accumulate 15,000–25,000 miles annually through work use. High mileage is less concerning on diesels than gasoline engines. We provide complete mileage verification.
Understand the condition of DPF, DEF, and EGR systems. Some donor trucks enter salvage from emissions failures with otherwise good engines. Verify emissions components are intact or budget for replacements. We document emissions system condition.
Verify turbo operates properly without excessive noise, smoke, or shaft play. Check for oil leaks from turbo seals. Inspect turbo impeller for damage. Failed turbos significantly reduce engine value. We test turbo operation when possible.
Check CP3 pump operation and fuel system cleanliness. Contaminated fuel systems from previous pump failures justify lower pricing or necessitate extensive cleaning. We inspect fuel systems for evidence of contamination.
Understand why donor vehicles entered salvage. Many diesel trucks total from collision damage, body deterioration, or frame issues while engines remain excellent. Rear-end and side-impact totals typically have perfect engines. We disclose complete source information.
All six cylinders should read within manufacturer specifications (typically 300–400 PSI depending on engine temperature) with less than 10% variation. Diesel compression testing requires proper procedure and equipment. We compression test when possible and document results.
Remove valve cover and inspect with proper lighting. Clean synthetic oil indicates proper maintenance. Heavy sludge or metallic debris suggests severe neglect or internal damage. Diesel engines require proper oil viscosity and change intervals. We document oil condition.
Verify engines include turbocharger, high-pressure fuel pump, fuel rails with injectors, EGR components, all sensors, and wiring harness. Missing diesel-specific components cost thousands to replace. We specify exactly what’s included.
When you purchase a 6.7 Cummins engine from 603 Auto Salvage, here’s what typically comes with your motor:
This comprehensive approach ensures you receive everything needed for successful installation without hunting for expensive diesel-specific components.
The 6.7 Cummins diesel enjoys exceptional longevity compared to gasoline engines:
With proper maintenance, 6.7 Cummins engines regularly exceed 400,000–500,000 miles. Many documented examples surpass 600,000–700,000 miles. Commercial applications routinely see 1,000,000+ miles with proper care and periodic rebuilds.
This exceptional durability means high-mileage used diesels remain viable. A 250,000-mile 6.7 Cummins has potentially another 250,000–350,000 miles remaining—far longer than most gasoline engines at similar mileage.
Heavy-duty diesel trucks retain value better than gasoline equivalents. The 6.7 Cummins commands premium pricing in used truck markets. This value retention justifies engine replacement investments that wouldn’t make sense for gasoline trucks.
For commercial users, work trucks generate revenue justifying repair investments. A $8,000 engine replacement on a truck generating $40,000+ annual revenue makes excellent business sense. Replacing rather than purchasing new saves $30,000–$50,000.
Understanding diesel economics helps frame replacement decisions differently than gasoline vehicle repairs.
Tom Sullivan, Concord NH
“My 2011 Ram 2500 developed fuel system contamination from CP3 pump failure at 287,000 miles. Dealer quoted $15,800 for complete engine replacement. Found 603 Auto Salvage with a 6.7 Cummins from 2012 with 198,000 verified miles for $8,200. My diesel specialist installed it for $4,500. Total $12,700 versus $15,800. Truck’s back working hauling equipment daily.”
Mike Chen, Manchester NH
“Run a small construction company with three older Ram diesels. Can’t afford dealer pricing. We’ve sourced two 6.7 Cummins engines from 603 Auto Salvage over three years. Quality has been excellent. Staff understands diesel engines and document condition honestly. Pricing lets us keep older work trucks running versus expensive new truck purchases.”
Robert Martinez, Nashua NH
“My 2015 Ram 3500 needed an engine from catastrophic turbo failure causing extensive damage at 312,000 miles. Found 603 Auto Salvage with a 6.7 from 2016 with 176,000 miles for $11,400. My mechanic installed it. Truck now runs excellent pulling my 30-foot gooseneck trailer. Saved probably $8,000 versus remanufactured options.”
Jennifer Wilson, Portsmouth NH
“Bought a non-running 2013 Ram 2500 cheap as a project knowing it had major engine issues. Got a 6.7 from 603 Auto Salvage with 224,000 miles but excellent compression for $7,800. Friend helped install it. Truck now runs great for my landscaping business. Total investment was $18,500 including the truck. Perfect work vehicle now.”
