Review CAN AM Mr Engine Motor Case Block fits OUTLANDER 570 2017–2023

The **AM 52879953 17-23 Outlander MR 570 Engine Motor Block** is a meticulously engineered, high-performance replacement component designed specifically for Mitsubishi s iconic **570 cc MR (Multi-Rotor) engine**, found in the **1998 2003 Outlander (Pajero) models**. This robust motor block represents the backbone of the vehicle s drivetrain, crafted from precision-cast **aluminum alloy** to deliver an optimal balance of strength, durability, and lightweight efficiency. The casting process ensures tight tolerances and smooth internal surfaces, which are critical for maintaining optimal compression ratios and minimizing friction within the engine s critical components. The block features **integrated cylinder bores** that align perfectly with the MR engine s unique multi-rotor design, allowing for seamless integration with the stock or upgraded pistons, rings, and connecting rods. Its **high-pressure die-cast construction** enhances resistance to thermal expansion and mechanical stress, making it ideal for both daily driving and demanding off-road conditions where the Outlander excels.

This motor block is engineered to meet or exceed **OEM specifications**, ensuring compatibility with the original engine s **camshaft drive system, oil passages, and mounting points**, while also accommodating aftermarket upgrades such as **high-flow gaskets, reinforced crankshaft bearings, or performance cylinder heads**. The **precision-machined surfaces** including the **main bearing caps, rod bolt holes, and oil gallery routes** are designed to work in tandem with modern lubrication systems, reducing wear and extending the engine s lifespan even under heavy loads. Whether used in a **restoration project, a performance rebuild, or as a direct replacement for a worn-out original block**, this component provides a solid foundation for restoring or enhancing the MR 570 s legendary reliability and torque output.

For enthusiasts and mechanics alike, the **AM 52879953 motor block** stands out as a **high-quality, drop-in replacement** that preserves the Outlander s heritage while accommodating modern tuning and maintenance practices. Its **rigorous quality control** ensures that every bore, deck surface, and oil passage meets strict dimensional standards, reducing the risk of leaks, misalignment, or premature failure. When paired with a **new crankshaft, pistons, and cylinder head**, this block can breathe new life into an aging MR engine, offering a **cost-effective alternative to sourcing a rare OEM replacement** while maintaining the integrity of Mitsubishi s legendary off-road powerplant. Whether restoring a classic Outlander or upgrading a project vehicle, this motor block delivers the **durability, precision, and performance** expected from a component built to exacting standards.

### **Pros and Cons of Buying a 1995 2003 Ford Outlander (MR 570 Engine, Motor Block #52879953)**

1. **Reliability and Durability** The MR 570 engine is a robust inline-six design known for lasting well beyond 200,000 miles with proper maintenance. Many examples from this era hold up better than expected, especially if the motor block is in good condition.

2. **Strong Performance** The MR 570 produces around 230 250 horsepower, making it capable of towing moderate loads (up to 5,000 6,000 lbs with proper setup) and providing smooth power delivery. It s a step up from the weaker 4.9L V8s found in earlier Outlanders.

3. **Proven Motor Block** The **52879953** block is a common and well-documented Ford casting, meaning parts, rebuild kits, and aftermarket support are widely available. It s not prone to catastrophic failure if maintained.

4. **Fuel Injection and Electronic Management** Unlike carbureted or early fuel-injected engines, the MR 570 uses a **Multiport Fuel Injection (MFI) system**, which is more reliable and easier to tune than older Ford fuel systems.

5. **Potential for Modifications** The MR 570 responds well to upgrades like **performance camshafts, headers, and fuel system enhancements**, making it a good candidate for power increases if you re mechanically inclined.

6. **Used Market Availability** Since these trucks are still common, finding one with a known-good MR 570 (especially with the correct block number) is easier than with rare or discontinued engines.

7. **Lower Running Costs (Compared to V8s)** While not fuel-efficient by modern standards, the MR 570 consumes less fuel than a 7.5L or 8.8L V8, reducing long-term operating costs.

---

1. **Age and Wear Concerns** At 20 years old, many MR 570 engines have accumulated miles. Without **regular valve adjustments, timing belt changes, and oil analysis**, internal wear (camshaft lobes, lifters, or bearings) can become an issue.

2. **Timing Chain vs. Belt** The MR 570 uses a **timing chain**, which lasts longer than a belt but can stretch or wear out over time. Some owners neglect chain inspection, leading to timing issues.

3. **Fuel System Vulnerabilities** The MFI system is better than carburetors, but **fuel injectors can clog**, and the **fuel pump** is a common failure point. A **fuel system flush and injector cleaning** are often needed after 150,000 miles.

4. **Transmission Wear** Many Outlanders from this era came with the **4R75E automatic**, which is known for **slippage, delayed shifts, and solenoid failures** if not serviced properly. A **transmission rebuild or fluid change** may be needed.

5. **Electrical and Sensor Issues** Older Ford trucks suffer from **failing sensors (MAF, TPS, crankshaft position)**, which can cause **check engine lights, rough idling, or stalling**. These repairs can add up.

6. **Suspension and Frame Rust** If the truck has seen **salt, off-roading, or poor storage**, the **frame rails, subframe, and suspension components** (control arms, bushings, shocks) may be rusted or worn.

7. **Emissions and Modern Compliance** Some states have **emissions testing**, and older trucks may fail due to **evaporative system leaks, O2 sensor failures, or PCM issues**. Retrofitting modern emissions gear can be costly.

8. **Resale Value and Parts Availability** While parts are still available, they are **not as cheap as they were 10 years ago**, and some aftermarket support has declined as Ford shifts focus to newer models.

### **Key Considerations Before Buying**

- **Compression test** (should be consistent across cylinders).

- **No oil leaks** (valve cover, oil pan, rear main seal).

- **No unusual noises** (ticking, knocking, or rattling under acceleration).

- **Service history** (timing chain, valve adjustments, fuel system work).

- **Smooth shifts** (no hesitation or jerking).

- **No burning smell** (indicates transmission fluid breakdown).

- **Transmission fluid color** (should be pinkish, not dark or burnt).

- **Rust in frame rails or subframe**.

- **Worn bushings or cracked control arms**.

- **Excessive play in steering or suspension**.

- **All lights, gauges, and warning lights**.

- **No check engine lights** (or at least a **free scan** to check for codes).

- **Battery and alternator health**.

- **No fuel leaks** (tank, lines, injectors).

- **Injectors spray evenly** (can be tested with a **fuel pressure gauge**).

- **Fuel pump priming** (no whining or failure to start).

---

### **Conclusion & Recommendation**

- **Find one with a well-maintained engine** (no major wear, proper fluid changes).

- **Budget for potential upgrades** (transmission service, fuel system refresh, suspension work).

- **Are prepared for some age-related quirks** (electrical issues, minor leaks, or emissions concerns).

**Best for:** Buyers who want a **reliable, capable work truck** with **good towing potential** and don t mind **some maintenance** to keep it running. It s a **stepping stone** to a newer truck or a **project** for someone comfortable with classic Ford repairs.

- You want a **plug-and-play, low-maintenance** vehicle.

- The truck has **neglected engine or transmission issues**.

- You re not willing to **invest in repairs** (fuel system, electrical, suspension).

- **If you find a clean example with a known-good MR 570, good transmission, and no major rust**, it can be a **solid buy** especially if you plan to **keep it for 5 10 years with proper care**.

- **Get a pre-purchase inspection** from a **Ford specialist** to catch hidden issues.

- **Budget at least $3,000 $5,000** for repairs and upgrades if buying used.

- **Consider a newer Ford Super Duty (2015 ) if reliability and warranty coverage** are top priorities.

The MR 570 is a **forgiving engine** when treated right, but like any older truck, it requires **attention and maintenance** to avoid costly failures. If you re willing to put in the work, it can be a **great long-term truck**.
