 Why People Buy Replacement V10s for Excursions

Excursions have become increasingly collectible, especially since Ford ceased production in 2005. With many examples racking up 200,000+ miles, engine swaps are becoming common — especially for those who tow RVs, horse trailers, or use the SUV for overlanding.

Common Reasons for Replacement:

• High Mileage Wear (rings, valves, bearings)

• Overheating Damage

• Blown Spark Plugs (yes, really)

• Cracked Cylinder Heads

• Oil Consumption and Valve Seal Failure

Whether your original V10 has given out or you’re doing a preemptive swap, getting a new or remanufactured V10 is often more cost-effective than a f Buying Options: Remanufactured vs. Used Engines

Let’s break down your main choices and where to find them.

Remanufactured Engines (Best for Warranty and Peace of Mind)

Top Reman Suppliers:

Pros:

• Fully rebuilt with new internals

• Warranty (3–5 years)

• Updated to fix known issues (spark plug threads, valve seats)

Cons:

• Higher upfront cost

• Core charges

• Long lead times in some regions

Used/Salvage Engines (Best for Budget Projects)

Found on eBay, salvage yards, or engine brokers. Prices range from $1,200 to $2,500 depending on mileage and condition.

• Google Motors: Ford Excursion 6.8L V10 Engine or E-Series vans (~$1,500–$3,000)

• Car-Part.com: Search nationwide salvage yards

• Local Junkyards: May offer install discounts

• LKQ Pick Your Part: Recycled engines with basic warranty

Cons:

• No warranty (or minimal)

• Unknown condition/mileage

• Possible compatibility issues

 Compatibility Notes (Ford F150 V8 Motor)

If you’re shopping for a used or reman engine, ensure you’re matching the following:

• VIN Match: Excursions typically used VIN “S” 2-valve V10s. Avoid VIN “Z” (3-valve) unless doing a custom swap.

• PCM/ECU: Check that the engine harness and ECM match your year/model.

• Transmission Bolt Pattern: Most V10s bolt to 4R100 or 5R110 transmissions—check for flywheel compatibility.

• Accessory Brackets: Some donor engines may come without alternator, A/C, or power steering brackets.

 Common Problems to Watch Out For (and How to Fix Them)

Even a new V10 isn’t perfect. Here are the most common issues:

 Spark Plug Blowout (Pre-2003)

• Why: Shallow threads in aluminum head can strip

• Fix: Install Time-Sert thread inserts or replace heads with updated design

 Coil Pack Failures

• Symptoms: Misfires, poor idle, stalling

• Fix: Replace with Motorcraft ignition coils only (cheap aftermarket fail quickly)

 Exhaust Manifold Leaks

• Cause: Corroded studs, broken bolts

• Fix: Use stainless manifold studs or aftermarket header kits

 Intake Manifold Cracks

• Fix: Upgrade to Dorman or aluminum intake manifold

 Oil Leaks (Valve Covers / Rear Main)

• Common in high-mileage units — inspect before install

 Installation Considerations Of Ford Excursion 6.8L V10 Engine

If you’re planning to do the engine swap yourself or with a mechanic, here are a few notes:

Tools/Skills Required:

• Engine hoist or lift

• Torque wrench set

• 2–3 days labor (DIY) or 8–12 hours shop time

• PCM reprogramming in some cases

Tips:

• Replace motor mounts, thermostat, spark plugs, coils, and rear main seal during install.

• If using a used engine, do a compression test and inspect for sludge/carbon deposits.

Installation Cost (Shop):

• Labor: $1,500–$2,500 (depending on region)

• Fluids, seals, misc parts: $300–$600

• Total: ~$2,000–$3,000 added to engine price

 Fuel Economy and Daily Driving 

Let’s be honest — the V10 was never meant to sip fuel. Expect:

• City: 7–9 MPG

• Highway: 10–13 MPG

• Towing: 6–8 MPG

Despite the low mileage, Ford Excursion 6.8L V10 Engine is smooth and powerful, and unlike diesels, it doesn’t suffer from emissions-related issues like DPF clogging or DEF refills.

• Flush coolant every 3 years

A well-maintained V10 is a beast — many fleet vehicles use this motor for 20+ years.
