Condition: What Fairly Used Means
Fairly used means the engine came out of a running vehicle, not from a fire or flood. It shows normal wear for its mileage, it is not rebuilt, and it is priced as a used engine. Anything we notice, such as soot around an injector or a weeping gasket, goes into your notes before you pay.
How We Check Each Mercedes OM612 Engine for Sale
- Record the engine number, mileage and donor vehicle where known
- Compression test on all five cylinders
- Inspect oil and coolant for contamination
- Look around the injectors for signs of leaking seals
- Check the turbo for play and the actuator for movement
- Listen for timing chain noise
- Inspect the block and head for cracks and repairs
- Photograph the engine from every side
- Drain, cap and pack for transport
Known OM612 Weak Points
- Injector seals. The copper washers can fail and let combustion gas escape, leaving black tar around the injectors. Fit new seals and hold-down bolts during the swap.
- Injector wear. High mileage injectors can leak back too much fuel.
- Intercooler hoses. Common on Sprinters. Split hoses cause power loss and limp mode.
- EGR and intake soot. Clean the intake during the swap.
- Fuel pressure faults. Pump, regulator and air leaks in the lines.
- Overheating in working vans. Blocked radiators and weak fan clutches.
These are normal wear points that good mechanics know well. They do not stop a Mercedes OM612 engine for sale being a smart buy.
Price and What Affects It
The price shown is for a complete, fairly used 2.7 litre engine. The final price can change with:
- Version: van, car or AMG
- Mileage
- Complete engine or long block
- Included parts such as injectors and turbo
- Shipping method and destination
Your quote lists the engine, parts and freight separately. See our guide to replacement engine cost to plan the full job.
Complete Engine or Long Block?
A complete engine includes the injectors, pump, rail, turbo and intake and is quickest to fit. A long block is the core only. A long block Mercedes OM612 engine for sale costs less and suits you if your own fuel system and turbo are healthy.
Used, Rebuilt or Remanufactured?
This listing is a fairly used engine, the cheapest and fastest option. Rebuilt and remanufactured engines cost more. Our guide to remanufactured vs rebuilt engines explains the difference. For a working van or a well kept ML, a tested used Mercedes OM612 engine for sale usually gives the best return.
Why Replace Like for Like
The OM612 sits between the four-cylinder OM611 and the six-cylinder OM613, and it was followed by the updated OM647 and the V6 OM642. They look similar in places, but lengths, wiring, fuel systems and engine computers differ. If your vehicle left the factory with an OM612, another one is the quickest fix. If yours has the V6, see our OM642 diesel engine page, and for newer four-cylinder vans the OM651 engine.
Notes for Sprinter Owners and Fleets
Many of our OM612 engines go into T1N Sprinters that work full days with heavy loads. When you fit the new engine, check the radiator and intercooler for blockage, replace boost hoses, look at the fan clutch and change the fuel filter. Fleets can order several engines at once and ship them together to save freight. Tell us how many vans you run and we will plan a Mercedes OM612 engine for sale for each.
Notes for ML270 and G270 Owners
These SUVs often work in dust, heat and water. Change the air filter, check the intake for dust or water damage and clean the radiator fins when you fit the new engine.
Fuel Quality
Common rail engines dislike water and dirt in the fuel. Fit a good water separating filter, drain it often and never run the tank nearly empty. Treat the fuel system well and a Mercedes OM612 engine for sale will treat you well in return.
Fitting Advice
- Fix whatever killed the old engine first.
- Fit new injector seals and hold-down bolts if in doubt.
- Replace intercooler hoses and clamps.
- Clean or replace the radiator and intercooler.
- Fit new fuel filters and bleed the system properly.
- Use the diesel oil Mercedes lists and change it early.
- Check the engine control unit suits the engine and vehicle.
Looking After Your New Engine
- Warm the engine up gently before working it hard.
- Let the turbo cool briefly after towing or long climbs.
- Avoid long idling.
- Watch the temperature gauge when towing in hot weather.
- Change oil and filters on time.
Notes for Workshops and Importers
We can quote several units together and ship them in one load. Many trade buyers order a Mercedes OM612 engine for sale alongside OM642 and OM651 units. Each engine is labelled with its number and quote reference, with photos and test notes for your customers.
A Short History of the Five-Cylinder Mercedes Diesel
Mercedes has built five-cylinder diesels for decades. The OM617 made the brand famous for diesel cars that would not die, and the OM602 and OM605 carried that idea into the 1990s. The OM612 brought it into the common rail era with four valves per cylinder, while keeping the iron block and five-cylinder layout people trusted. That is why mechanics almost everywhere are comfortable with it, and why buying a Mercedes OM612 engine for sale is not a leap into the unknown.
Signs a Replacement Makes Sense
Many OM612 faults are simple repairs. A replacement engine becomes the better value when you have:
- A knock from the bottom end from a spun bearing.
- A cracked head or block after overheating.
- Coolant in the oil that keeps returning.
- Low compression on several cylinders.
- A head badly eaten away by years of leaking injector seals.
- Valve damage after a timing chain failure.
Send the symptoms or a workshop report and we will tell you honestly whether a Mercedes OM612 engine for sale is the right call.
What Your Workshop Will Need
The OM612 is a straightforward engine to fit. Plan for new injector seals, fresh coolant, the correct diesel oil, new fuel filters and new gaskets for any parts moved from the old engine. On Sprinters, replace the boost hoses and check the engine mounts while everything is apart. Ask your mechanic to bleed the fuel system properly before the first start, because air in a common rail system causes hard starting. With that done, fitting a Mercedes OM612 engine for sale is routine work for any diesel workshop.
Matching the Engine to Your Vehicle
