We sell engines, nothing else. A Detroit Diesel Series 60 engine for sale is one of the most common requests we get from truck owners, bus operators and equipment shops who need a proven heavy diesel without paying new engine money.
Below you will find the specs, the trucks it went into, the differences between the 11.1, 12.7 and 14 litre versions, the problems worth knowing about, how we test, and how buying from us works.
Why a Detroit Diesel Series 60 Engine for Sale Still Makes Sense
Detroit Diesel launched the Series 60 in 1987. At the time it was a big step. It was one of the first heavy truck engines built from day one with full electronic control, and it used an overhead camshaft at a time when most of its rivals still pushed rods. The result was a smooth, fuel efficient inline six that drivers liked and mechanics could work on.
It sold in huge numbers. For a long stretch of the 1990s and early 2000s it was the most popular Class 8 engine in North America, and it went on to power buses, fire trucks, cranes, boats and generators around the world. That popularity is exactly why a Detroit Diesel Series 60 engine for sale is still easy to support today. Parts are everywhere, almost every heavy truck mechanic knows it, and rebuild kits cost far less than parts for newer emissions engines.
The other reason people keep buying them is simplicity. A pre-EGR 12.7 has no particulate filter, no DEF and no exhaust gas recirculation. For buyers in countries with older emissions rules, or for anyone rebuilding a glider or an older truck, that matters a lot.
Detroit Diesel Series 60 Engine Specifications
The figures below cover the common truck versions of the Detroit Diesel Series 60 engine for sale in our stock. Exact ratings depend on the year, the DDEC calibration and what the engine was built for, so we always confirm the details from the data plate before quoting.
| Engine type | Inline 6 cylinder, four stroke turbo diesel |
| Displacements | 11.1 litres, 12.7 litres and 14.0 litres |
| Bore x stroke (12.7L) | 130 mm x 160 mm |
| Bore x stroke (14.0L) | 133 mm x 168 mm |
| Valve train | Single overhead camshaft, 4 valves per cylinder |
| Fuel system | Electronic unit injectors, cam driven |
| Engine control | DDEC II, III, IV, V and VI depending on year |
| Horsepower | About 330 to 500 hp (12.7L), up to about 515 hp (14.0L) |
| Peak torque | Up to about 1,650 lb-ft (12.7L) and 1,850 lb-ft (14.0L) |
| Firing order | 1-5-3-6-2-4 |
| Dry weight | Roughly 2,600 to 2,700 lb depending on version |
| Production | 1987 to about 2011 for on-highway trucks |
If you are comparing a Detroit Diesel Series 60 engine for sale from different sellers, ask for the engine serial number and the DDEC version first. Those two details tell you more about fit and wiring than the horsepower figure does.
Which Trucks and Machines Use the Series 60?
The Series 60 was offered by almost every North American truck builder at some point. The most common homes for it were:
- Freightliner FLD 120, Classic, Century Class, Columbia and Coronado
- Peterbilt 377, 378, 379 and 385
- Kenworth W900, T600 and T800
- Western Star 4900 and 5900 series
- International 9000 series and some Volvo and Sterling models
- Motor coaches and transit buses from MCI, Prevost and others
- Fire apparatus, cranes, marine propulsion and standby generators
The Peterbilt 379 in particular is a truck you will see with a Series 60 under the hood all over the world. Because the engine went into so many chassis, the accessories, oil pan, flywheel housing and wiring can differ a lot from one truck to the next. That is the main reason we ask what the engine is going into before we ship anything.
11.1 vs 12.7 vs 14 Litre: Which Version Do You Need?
The 11.1 litre was the early engine, mostly found in late 1980s and 1990s trucks and buses. It is lighter and was popular in fleet trucks that did not need big power. Good examples are harder to find now.
The 12.7 litre is the one most people mean when they say Series 60. It was built for the longest time and in the biggest numbers, and the DDEC IV 12.7 from the late 1990s and early 2000s, before EGR, is the version many drivers rate as the best of the lot. If you want a Detroit Diesel Series 60 engine for sale with the fewest headaches, this is usually the one we point people to.
The 14.0 litre arrived in the early 2000s for owners who wanted more torque for heavy haul and mountain work. Most 14 litre engines carry EGR, which adds parts to look after but also gives you more pulling power.
Pre-EGR and EGR engines
From late 2002 the Series 60 picked up exhaust gas recirculation to meet tighter US emissions rules. EGR engines have a cooler, a valve, extra sensors and a variable geometry turbo. They work fine when maintained, but they cost more to keep running. 2007 versions also gained a diesel particulate filter in the exhaust. If you can legally run a pre-EGR engine where you are, it is usually the simpler choice. If your truck was built with EGR, the swap back is not always straightforward, so tell us what you have and we will help you weigh it up.
DDEC Versions and Wiring
DDEC is the Detroit Diesel Electronic Control system, and it changed several times over the life of the engine. DDEC II and III are found on older engines, DDEC IV covers roughly 1998 to 2002, and DDEC V and VI came in with the EGR era. Each one uses different harness connectors and different software.
You can sometimes put a newer engine in an older truck, but the ECM, harness and sometimes the dash wiring have to go with it. When you buy a Detroit Diesel Series 60 engine for sale from us we tell you which DDEC version it carries and whether the ECM is included, so there are no surprises once it arrives.
Known Series 60 Weak Spots
No engine is perfect, and even a good Detroit Diesel Series 60 engine for sale has a few habits worth knowing about before you buy.
- EGR cooler failures. On EGR engines the cooler can crack and leak coolant into the intake. White smoke and coolant loss are the warning signs.
- Cylinder liner cavitation. Poor coolant care can pit the liners from the water side. Good coolant and correct additive levels prevent it.
- Cam follower and rocker wear. High mileage engines can show wear on the overhead cam gear. We check this when we inspect.
- Oil consumption. Some engines start using oil as rings and liners wear, especially after hard idling.
- Sensor and harness faults. Old wiring gets brittle. Many running problems turn out to be a connector, not the engine.
- Head gaskets on EGR engines. Overheating from a plugged cooler can push a gasket.
None of these are reasons to avoid the engine. They are reasons to buy a Detroit Diesel Series 60 engine for sale from someone who actually looks for them.
How We Test Every Detroit Diesel Series 60 Engine for Sale
Here is what happens before any Detroit Diesel Series 60 engine for sale leaves our yard:
- We record the engine serial number, the DDEC version and the rating from the plate.
- We run a compression or cylinder cut-out test to check every cylinder is doing its share.
- We look at oil condition and check for coolant or fuel in the oil.
- Where the engine can be run, we run it and check oil pressure, blow-by and smoke.
- We check the turbo for shaft play and the cooler for leaks on EGR engines.
- We look over the overhead for cam and rocker wear when the valve cover is off.
- We photograph the engine from every side and send you those exact photos.
You get the real results with your quote. If something is worn, we say so. You can read more about our process in our guide to tested used engines.
What Comes With the Engine
Most Detroit Diesel Series 60 engine for sale listings in our stock are sold as complete engines. That usually means the block, head, injectors, turbo, manifolds, oil pan and front cover. Some engines come with the ECM and part of the harness. Accessories like the air compressor, power steering pump, starter and alternator vary from engine to engine.
We list exactly what is included on every quote. If you only need a long block, say so and we can price that instead. It often saves money when your old accessories are still good.
Used, Rebuilt or Remanufactured?
Used engines come out of running trucks and are sold after testing. They cost the least and make sense when the truck has a few more years of work in it.
Rebuilt engines are the next step up from a used Detroit Diesel Series 60 engine for sale. They have been opened up and had worn parts replaced, usually liners, pistons, rings, bearings and gaskets. They cost more but restart the clock on the main wear items.
Remanufactured engines go back to factory measurements across the whole engine. They are the most expensive option.
Most of our buyers choose a tested used Detroit Diesel Series 60 engine for sale because it gets the truck back to work for the lowest cost. We are happy to talk through which option fits your budget.
7 Checks Before You Buy Any Detroit Diesel Series 60 Engine for Sale
1. Match the serial number and version
Before you pay for any Detroit Diesel Series 60 engine for sale, find the engine serial number on your old block or data plate. It tells you the displacement, the build and often the original rating. Matching it is the fastest way to avoid a mismatch.
2. Confirm the DDEC version
Your truck harness was built for one DDEC version. Know which one you have before you buy.
3. Ask for compression or cut-out results
A seller who tested their Detroit Diesel Series 60 engine for sale can show you the numbers. A seller who did not will tell you it runs good.
4. Ask for real photos
Stock photos tell you nothing. Ask for pictures of the actual engine, including the serial plate.
5. Check the EGR parts
If the Detroit Diesel Series 60 engine for sale is an EGR model, ask about the cooler and valve condition. A failing cooler is an expensive fix.
6. Know what is included
Two listings for a Detroit Diesel Series 60 engine for sale can look alike and still be very different deals. Turbo, injectors, ECM, flywheel and accessories all change the real price. Get the list in writing.
7. Read the warranty
Know how long it lasts and what it covers before you pay. Our used engine warranty guide explains what to look for.
What Affects the Price
The price of a Detroit Diesel Series 60 engine for sale depends on displacement, mileage, DDEC version, condition and what is bolted to it. A clean pre-EGR 12.7 with low miles usually costs more than an EGR engine with high hours, because demand for the older engine is stronger. Fourteen litre engines also tend to sit near the top of the range.
Shipping is the other big piece. A complete Series 60 weighs well over a ton once it is crated, so freight to your country can be a real part of the total. We include freight options in your quote so you can compare properly. For a wider view, read our guide on replacement engine cost.
Worldwide Shipping
We ship engines to buyers across Africa, Europe, the Middle East, Asia, Latin America, the Caribbean and North America. Each engine is drained, sealed, strapped to a pallet or crated and shipped by sea or road freight with tracking. We prepare the export paperwork and work with your clearing agent at the destination port.
Our shipping policy explains timing and how freight is handled. Ask us for a door or port price when you request your quote.
Installation Tips
When your Detroit Diesel Series 60 engine for sale arrives, a few things make the install go smoother:
- Flush the cooling system and radiator. Old debris can damage a good engine fast.
- Replace or clean the charge air cooler if the old engine failed with oil or metal in the intake.
- Fit new filters and fresh oil before first start, and prime the fuel system.
- Check the ECM settings, road speed limits and cruise settings match your truck.
- Let it idle and come up to temperature, then check for leaks before the first load.

Series 60 vs Newer Detroit Engines
The Series 60 was replaced in trucks by the DD15 from around 2008, and production for road trucks wound down by 2011. The DD15 is more fuel efficient and meets newer emissions rules, but it is also more complicated, with common rail injection and a full aftertreatment system. If you are weighing the two, read our guide to the Detroit DD15 engine for sale.

How Long Does a Series 60 Last?
A well kept 12.7 can go a million miles before it needs an in-frame overhaul, and we have seen plenty that went further. The ones that die early usually share the same story: dirty coolant, long periods of idling, skipped oil changes or an overheating event that nobody caught in time. Dust is another killer in hot, dry countries, so an air filter that seals properly matters as much as the oil.
When you look at a Detroit Diesel Series 60 engine for sale, the mileage on the ECM is useful but it is not the full picture. A 600,000 mile engine from a highway truck that was serviced on time can be in better shape than a 300,000 mile engine that sat idling on a job site all day. That is why we test instead of relying on the odometer.
Simple habits that add years
- Change oil and filters on schedule, and use the right heavy duty grade.
- Keep coolant clean and test the additive level so the liners stay protected.
- Avoid long idling. It loads up the engine and dilutes the oil.
- Fix small leaks early, especially around the turbo and EGR parts.
- Do a valve and injector adjustment at the intervals in the service manual.
Buses, Generators and Marine Use
Not every buyer runs a truck. A good share of the Detroit Diesel Series 60 engine for sale requests we handle come from coach operators, farms, mines, hospitals and boat owners.
Coaches and buses. The Series 60 powered a lot of highway coaches. If you want a Detroit Diesel Series 60 engine for sale for a coach, keep in mind that rear mounted bus engines often use different oil pans, fan drives and cooling setups from truck engines, so we always check the application before quoting.
Generators. Standby and prime power sets ran the Series 60 at a fixed speed. These engines often have low hours because standby sets spend most of their life waiting. They can be a smart buy if the cooling and fuel system match what you need.
Marine. Marine versions use heat exchangers, wet exhaust and their own ratings. A road truck engine is not a direct swap into a boat, so tell us the hull and gearbox and we will look for the right match.
Whatever the job, a Detroit Diesel Series 60 engine for sale from us comes with the same testing and the same honest description.
Questions We Ask Before Quoting
To find the right Detroit Diesel Series 60 engine for sale for you, we usually ask:
- What is the engine serial number on your old engine?
- What truck, bus or machine is it going into, and what year?
- Do you need the ECM and harness, or are you keeping yours?
- Do you want a complete engine or a long block?
- Which port or city should we ship to?
With those answers we can send a quote with photos, test results and freight costs, usually the same day.
