Introduction: Why Inspection is Important When Purchasing a Mitsubishi Engine

Mitsubishi engine inspection guide. Whether you’re buying a reconditioned Mitsubishi engine to replace one that’s crashed or restoring a car, inspection is important. A second-hand or reconditioned engine might look like a deal—until you install it and have issues like oil leaks, low compression, or overheating. That’s why thorough inspection is necessary.

Here at [Your Company Name], we’re specialists in quality-tested used Mitsubishi engines that are guaranteed to run. Even when buying from a reputable seller such as ourselves, we believe you should be aware of what to inspect. This guide walks you through a detailed checklist, including DIY advice on what to inspect and how our team ensures the engines we’re selling are reliable, durable, and worth every penny.

Why Purchase a Used Mitsubishi Engine?

Let us address a simple question before we work on the inspection process: Why purchase a used Mitsubishi engine?

1. Affordable

Used engines are significantly less expensive than a new one. You save as much as 60–70% on the cost of a new engine while still getting to enjoy Mitsubishi’s established quality. Mitsubishi engine inspection guide

2. Solid Engineering

Mitsubishi engines are built to stand the test of time. In regular inspection and maintenance, even used units can last for years with trouble-free performance. Mitsubishi engine inspection guide

3. Years of Reliability Service

There is a used Mitsubishi engine inventory from 4G63 to 4M41 all over the world. You have options whether you’re driving a Lancer, Pajero, Triton, or Outlander.

4. Eco-Friendly

Reuse is waste-free and factory emission-free. You’re saving money and the earth.

🔍 We provide carefully examined, high-quality Mitsubishi engines for all models. Every unit we ship goes through a detailed inspection checklist like the one below. Mitsubishi engine inspection guide

Mitsubishi Engine Inspection Guide: Step-by-Step Checklist

Here is the step-by-step process on how to inspect a used Mitsubishi engine. If you are purchasing from a local market or individual, you would have to do this checklist. If you are purchasing from us, don’t worry because we do all these before selling an engine. Mitsubishi engine inspection guide

1. Check the Exterior Condition of the Engine

✅ Look for Oil Leaks

Inspect the cylinder head, valve cover, and oil pan. Oil leaks or heavy buildup may indicate worn gaskets or seals.

✅ Rust and Corrosion

Surface rust is okay in some climates, but severe corrosion can affect performance. Check around the exhaust manifold and coolant lines. Mitsubishi engine inspection guide

✅ Mounting Points

Check for broken or worn mounting brackets and stripped bolt threads. A poorly unbolted engine might have taken some damage.

🧼 Our Used Mitsubishi Engines are thoroughly dismantled, cleaned, and available for resale. We strip corrosion and rebuild worn-out outer components as needed. Mitsubishi engine inspection guide

2. Inspect the Cylinder Head and Valve Cover

✅ Valve Cover Gasket

Take off the valve cover (if accessible) and inspect the gasket. Cracks or heavy wear are indications of age and potential oil leaks. Mitsubishi engine inspection guide

✅ Sludge Buildup

Tar-like, heavy sludge in the valve train is a caution sign. It represents neglected oil maintenance. Avoid such engines. Mitsubishi engine inspection guide

🛠️ We service and check the engine components inside before resale. Sludge-friendly engines fail our inventory.

3. Compression Test

Compression tests evaluate the health of the piston rings and combustion chamber.

✅ Good Compression Levels

For Mitsubishi engines, ideal cylinder compression is 160–210 psi and no more than 10% difference from cylinder to cylinder.

✅ Dry and Wet Tests

A wet compression test (adding a little oil in the cylinder) helps to differentiate between ring and valve problems.

📊 We compression test all our engines. Reports can be supplied on request for most units.

4. Inspect the Spark Plugs and Ignition System

✅ Spark Plug Tips

Remove spark plugs and inspect them for fouling, oil, or excessive carbon buildup. That tells you a lot about engine performance.

✅ Ignition Coils

Check coils and wiring harnesses for wear or damage.

🔌 We also include ignition components in good shape or notify you in advance if they are not included.

5. Check the Timing Belt or Chain

✅ Belt/Chain Condition

Timing belts should never be cracked or missing teeth. Chains should be properly tensioned and not rattle.

✅ Tensioner and Pulleys

Worn-out tensioner will make timing fail. Check for free-running pulleys.

⛓️ We renew old timing components before resale. You will never get an engine from us with a timing belt or chain failing.

6. Check Engine Sensors and Electronics

✅ Oxygen Sensor, MAP, MAF, and Knock Sensors

These should be present and in good working condition. Broken or missing sensors create check engine lights.

✅ Compatibility of ECU

Make sure that the engine’s ECU is compatible with your car, especially if you are performing an engine swap across various Mitsubishi models.

💡 Our team helps equalize the correct ECU and harnesses for your model. Ask about plug-and-play availability.

7. Check the Exhaust Manifold and Gasket

Leaks or cracks within the exhaust manifold or exhaust leak symptoms (like black soot) are serious issues.

🧰 We inspect all manifolds visually and regularly replace gaskets during our reconditioning process.

8. Cooling System and Water Pump Inspection

✅ Radiator Ports and Hoses

Check for corrosion or cracked connectors.

✅ Water Pump Test

Turn the pulley—there should be no wobble or grinding. Leaks from the weep hole indicate pump failure.

💦 We leak check the cooling system and regularly replace pumps as necessary before selling the engine.

9. Oil Pan and Drain Plug

Inspect for broken pans or damaged threads. Shavings in the oil are a huge red flag.

🛢️ All of the engines at our shop have the oil pan removed and checked for debris before they’re cleared for sale.

10. Listen to the Engine (If It’s Running)

If you can listen to the engine rev before pulling or putting it in, listen for rough idle, knocks, or misfires. This is typically the most revealing inspection method.

🔊 We test drive much of our Mitsubishi engines before removal. Ask for running video or test report.

Items to Watch Out for in Pre-Owned Mitsubishi Engines

Even with best inspection, beware of the typical traps specific to Mitsubishi powerplants:

⚠️ We test our stock for these issues and fix them before we sell. No surprises.
