4. Quick Answer

What is a used 6.4 Powerstroke engine? It is a factory Ford/International 6.4L Power Stroke diesel V8 removed from a donor 2008 to 2010 Super Duty truck, typically after an accident or a total loss rather than an engine failure. It is sold as a long block or complete engine assembly through independent sellers rather than manufactured new.

How much does a used 6.4 Powerstroke engine cost? Used 6.4L Powerstroke engines generally run $2,500 to $6,000, depending on mileage, documentation, and what accessories are included. A comparable remanufactured 6.4L typically starts around $9,000 and can exceed $13,000 before installation labor.

Why do buyers choose a used 6.4 Powerstroke over a remanufactured one? A used OEM engine costs a fraction of remanufactured pricing, uses factory components rather than a rebuild with mixed parts, and is usually available faster since it already exists rather than needing to be built to order.

How does Used Auto Parts Pro help? UAPP matches your VIN to compatible 6.4L Powerstroke listings across its seller network and lets you compare quotes. We do not inspect, test, warehouse, or ship the engines ourselves; those steps are handled by the individual seller, and terms vary from one seller to the next.

5. Key Takeaways

• The 6.4L Powerstroke was built for a short, single production run (2008 to 2010) in the Super Duty lineup, so applications are more consistent than longer-running engines, but documented mileage and maintenance history still vary a lot from one used unit to the next.
• Typical used pricing runs $2,500 to $6,000; remanufactured pricing typically starts around $9,000 and climbs from there before labor.
• The 6.4L is Ford’s first Power Stroke with a diesel particulate filter (DPF) and exhaust gas recirculation (EGR) system to meet 2007 emissions standards. Removing or bypassing these components is illegal for on-road use under federal and most state law, separate from any performance modification claims you may see elsewhere.
• A VIN match gives strong fitment confidence, but it is not an absolute guarantee. Confirm the physical engine code against the listing before you buy.
• Warranty terms are set by the individual seller, not by UAPP, and vary by seller and by part. Get warranty terms in writing before purchase.
• Inspection and testing practices vary by seller. Ask directly rather than assuming every listing was tested the same way.
• Shipping cost is included in the seller’s quoted price for the contiguous 48 states; it is not a separate line item and it is not advertised as free.
• Unlike Ford’s earlier 6.0L Power Stroke, there is no confirmed, widely documented class-action settlement specific to the 6.4L as of this writing. It shares some regulatory and design lineage with the 6.0L, but the two should not be treated as the same legal or reliability story. Check NHTSA directly for the most current recall status on your specific VIN.

6. Engine Overview: What the 6.4 Powerstroke Is

What Is the Ford 6.4 Powerstroke Engine?

The 6.4L Power Stroke is a twin-turbocharged diesel V8 jointly developed by Ford and International (Navistar), built for a single generation from 2008 to 2010 in the Super Duty lineup. It replaced the 6.0L Power Stroke and was itself replaced by the 6.7L Power Stroke starting with the 2011 model year. In stock form it produced roughly 350 horsepower and 650 lb-ft of torque, a meaningful jump over the 6.0L it replaced.

Applications: 2008 to 2010 Ford F-250 Super Duty, F-350 Super Duty, F-450 Super Duty, and F-550 Super Duty, in both pickup and chassis-cab configurations.

Production run notes. Because the 6.4L had only a three-model-year run, there is not a major internal generation split the way there is with longer-running engines like the 5.4L Triton or 6.7L Power Stroke. That said, Ford made calibration and component running changes over the course of production as early field issues came in, so a 2008 model-year engine is not guaranteed to have identical part numbers to a 2010 unit even though both are called “6.4L Power Stroke.” Confirming the physical engine code and production date against your VIN still matters.

Emissions equipment. The 6.4L was the first Power Stroke built to meet the EPA’s 2007 diesel emissions standards, which means it carries a diesel particulate filter (DPF) and EGR cooler system that earlier Power Strokes did not have. Removing or bypassing DPF or EGR components is illegal for on-road use under federal and most state law. This is separate from any manufacturer settlement or recall history and is worth knowing before you buy a used engine that someone may have modified.

7. Benefits of a Used 6.4 Powerstroke Engine

Why buy used OEM instead of remanufactured? A used 6.4L Powerstroke is a factory-built engine that already ran in a real Super Duty, at a fraction of remanufactured pricing, and it is generally available faster because it does not need to be built to order.

• Lower cost per mile of remaining life. A well-documented, lower-mileage pull can offer meaningful service life at a fraction of remanufactured pricing.
• Factory-correct fit. A used 6.4L pulled from another Super Duty uses the same mounting points, turbo plumbing, and wiring architecture your truck already expects.
• Faster turnaround. Used engines already exist in a seller’s yard rather than needing to be built, so they are typically available to ship sooner than a custom remanufactured order.
• A track record you can partially verify. Where mileage and service history are documented, you get more insight into a specific engine’s condition than you would with a mixed-parts rebuild.

8. Compatibility: What Actually Determines Fitment

Does every 6.4 Powerstroke fit every Super Duty that used one? Mostly yes at the core engine level, since the 6.4L had a short, relatively consistent production run, but accessory brackets, turbo plumbing, and PTO provisions can differ between an F-250 pickup and an F-450/F-550 chassis-cab built for commercial upfitting.

How does VIN matching help? Submitting your 17-digit VIN lets sellers in the UAPP network match your truck’s original engine code, model year, and platform to compatible listings. This gives strong fitment confidence and meaningfully narrows the field, but it is not an absolute guarantee of fit. Always confirm the physical engine code stamped on the block against the seller’s listing before finalizing a purchase, and ask whether accessories, the oil pan, and the flexplate are included, since these can differ by application even within the same engine code.

Common buyer mistakes worth avoiding:

• Assuming a pickup-spec 6.4L will bolt in cleanly to an F-450/F-550 commercial chassis without checking accessory and PTO differences.
• Assuming the 6.4L is interchangeable with the 6.0L it replaced or the 6.7L that replaced it; none of the three generations share the same block, turbo system, or emissions hardware.
• Buying based on model year alone without confirming the 8th-character engine code on the VIN and the physical engine tag.

9. Common Problems With the 6.4 Powerstroke

What commonly goes wrong with the 6.4 Powerstroke? The issues below are well documented in the diesel repair community, and most show up in a similar mileage window; none of them mean every used 6.4L is a bad buy, but they are worth asking about directly.

Oil dilution from fuel. The 6.4L uses a fuel-based DPF regeneration strategy that injects extra fuel into the exhaust stroke to burn off soot. In trucks used mostly for short trips or heavy stop-and-go work, unburned fuel can work its way past the rings and dilute the engine oil over time, which shortens oil life and can accelerate wear if oil changes are not kept current.

EGR cooler and cracked piston issues. EGR cooler failures can allow coolant into the intake or combustion path, and cracked pistons have been documented on high-mileage or hard-worked units, most commonly in trucks used for towing or fleet work. Both issues tend to show up somewhere in the 120,000 to 180,000 mile range, though this varies with maintenance and use.

High-pressure fuel pump and injector concerns. Like other high-pressure common-rail diesels, the 6.4L’s fuel system is sensitive to fuel quality and contamination. A failing high-pressure pump can send metal debris through the fuel system, which is why sellers and buyers alike should treat fuel system history as a real question, not an afterthought.

DPF and regeneration complications. Clogged or failing DPF systems can trigger reduced power modes or force frequent regeneration cycles. A check engine light or a DPF warning alone does not necessarily mean the engine itself needs replacement; it is worth having a shop diagnose the actual cause before assuming the worst.

10. Inspection and Quality Standards

Are used 6.4 Powerstroke engines tested before sale? Inspection and testing practices vary by seller and by engine; there is no single industry-wide standard applied to every listing in the UAPP network. Ask each seller directly:

• Is documented mileage available, and does it come from the donor truck’s title, dashboard photo, or a CARFAX-style record?
• Was a compression test performed, and can the results be shared in writing?
• Is there a run video or cold-start video available?
• Has the EGR cooler, high-pressure fuel pump, or DPF condition been checked or serviced?
• What does the engine include: turbos, accessories, oil pan, flexplate, sensors, wiring harness?

11. Warranty Information

Do used 6.4 Powerstroke engines come with a warranty? Warranty coverage is not standardized across the marketplace. It varies by seller and by part, and is set individually by each seller rather than by UAPP. Some sellers offer 30-day, 60-day, or longer warranties on the engine itself; others sell as-is. Warranties typically cover the engine assembly and usually exclude labor, consumables, and damage from improper installation. Always get warranty terms in writing before purchase, and confirm exactly what is and is not covered, including turbos and fuel system components.

12. Shipping Information

How is a used 6.4 Powerstroke engine shipped? Shipping cost is included in the seller’s quoted price for the contiguous 48 states; it is not billed separately and it is not offered as a free add-on. Given the engine’s weight, most 6.4L units ship via LTL freight on a pallet, typically within 3 to 10 business days depending on the seller’s location and your destination. Alaska and Hawaii shipments usually take longer; ask your seller for a specific timeline before you commit to a quote.

13. Buying Guide

How do I buy a used 6.4 Powerstroke the right way?

1. Confirm your engine code. Check your VIN’s 8th character and the physical engine tag to confirm you are getting a genuine 6.4L Power Stroke and not a 6.0L or 6.7L listed incorrectly.
2. Submit your VIN through UAPP. This lets sellers in the network match listings to your specific Super Duty configuration.
3. Compare quotes, not just price. Look at mileage, documentation, what is included (turbos, accessories, oil pan), and warranty terms side by side.
4. Ask about fuel system and DPF history. Given the 6.4L’s documented weak points, ask specifically about high-pressure fuel pump, EGR cooler, and DPF condition, not just general running condition.
5. Confirm installation requirements. Ask whether the engine includes the wiring harness and sensors your specific application needs, and whether any PCM programming will be required.
6. Get everything in writing. Price, warranty terms, what is included, and estimated shipping timeline should all be confirmed in writing before you pay.

14. Installation Considerations

Installing a 6.4L Powerstroke is a major job that most owners have a diesel shop handle rather than a home garage project. A few things worth planning for:

• PCM and emissions system compatibility. The replacement engine’s emissions calibration needs to match or be properly programmed to your truck’s PCM, particularly if the donor engine came from a different production run within the 2008 to 2010 window.
• Turbo and accessory transfer. Turbochargers, the high-pressure oil pump, and accessories are sometimes transferred from your original engine rather than included with the used long block. Confirm what the listing includes before assuming a plug-and-play swap.
• Wear-item replacement. Given the labor already involved in a diesel engine swap, most shops recommend replacing gaskets, the EGR cooler if not recently serviced, and fluids at the same time rather than reusing worn parts.
• Emissions system integrity. Never install a used 6.4L with a deleted or bypassed DPF/EGR system for on-road use; doing so is illegal under federal and most state law regardless of who performed the modification originally.

15. Why Choose Used Auto Parts Pro

• Verified seller network. UAPP works with vetted salvage yards and engine sellers across the country rather than an anonymous listing board.
• VIN-based matching. Submitting your VIN gives you strong fitment confidence for your specific F-250, F-350, F-450, or F-550 Super Duty.
• Nationwide reach. More sellers in the network means more chances to find a well-documented, lower-mileage 6.4L Powerstroke.
• Transparent, quote-based pricing. Shipping cost is included in your seller’s quote, with no separate freight surprise later.
• OEM-first, with transparency on alternatives. UAPP prioritizes OEM used engines, and where a seller lists a remanufactured or non-OEM-component unit, that distinction is disclosed so you can choose what fits your budget and expectations.
• Marketplace transparency. UAPP does not hold inventory and does not sell engines directly; we connect you to sellers and let you compare their terms.
