Chapter 1: Mitsubishi Engine Issues

Knowing what you’re up against before you can diagnose is a good thing. Mitsubishi engines, like all others, have some problems which occur more frequently. They are:

1.1 Overheating

Overheating is to be anticipated in motors with dirty radiators or poorly functioning water pumps. In older Mitsubishi motors like the 4G63 or 6G72, overheating is caused by a stuck thermostat, insufficient coolant, or blown head gasket. Used Engine Troubleshooting For Mitsubishi

1.2 Oil Leaks

Oil pan gasket or valve cover gasket leaks are common after extensive use. Engine damage and low oil pressure result from a leak that is ignored. Used Engine Troubleshooting For Mitsubishi

1.3 Timing Belt Failure

Some of the Mitsubishi engines are interference engines—if the timing belt breaks, it creates catastrophic engine destruction. That is usually the issue with vehicles such as the 4G64. Used Engine Troubleshooting For Mitsubishi

1.4 Engine Knocking or Tapping Noise

Engine knocks are an indicator that the engine will require bearings or piston slap to be replaced or experience detonation issues. These are pre-ignition precursors that the engine might require to be replaced. Used Engine Troubleshooting For Mitsubishi

1.5 Rough Idling or Stalling

This is caused by faulty fuel injectors, plugged throttle bodies, or faulty spark plugs. In other used engines, the trouble is a faulty idle air control valve. Used Engine Troubleshooting For Mitsubishi

Chapter 2: Diagnosing a Used Mitsubishi Engine

You don’t need to be a professional mechanic to diagnose your engine. Just follow these step-by-step procedures to know what’s wrong with your Mitsubishi engine. Used Engine Troubleshooting For Mitsubishi

2.1 Inspection of Engine Codes

Later Mitsubishi engines have onboard diagnostics (OBD-II). Scan for codes using a scanner—these can indicate ignition, sensor, or fuel system problems.

2.2 Listen and Look

Raise the hood and listen for strange noises—knocks, ticks, or hissing. Check for smoke, leaks, and worn-out belts. Used Engine Troubleshooting For Mitsubishi

2.3 Check Compression

Compression checks show whether internal components like pistons, rings, or valves are worn. Low or uneven compression means serious internal wear. Used Engine Troubleshooting For Mitsubishi

2.4 Check for Coolant and Oil Mix

Milky oil or coolant in the oil pan is an indication of a blown head gasket—one of the most common reasons that individuals end up with Mitsubishi engines replaced. Used Engine Troubleshooting For Mitsubishi

2.5 Check for Sludge

Pop the oil cap off and check. If you notice sludge or burned oil, the engine may not have been properly serviced.

In case you are facing any of the above problems, replacement time is already here. That is where our second-hand Mitsubishi engines fit in. Used Engine Troubleshooting For Mitsubishi

3.1 The Repairs Cost More Than a Replacement

Sometimes it is more costly to repair a worn engine than to just replace it. Rebuilt head, new gaskets, and timing components can quickly add up.

3.2 Severe Internal Damage

If your engine has thrown a rod, destroyed a bearing, or has a cracked block, you’d be better off to replace it.

1. Oil Leaks in Used Mitsubishi Engines

🚩 The Problem:

Reconditioned Mitsubishi engines, especially the older models such as the 4G63 or 6G72, will oil leak around the valve cover gasket, crankshaft seals, or oil pan. Mitsubishi engine problems

🛠️ The Fix:

  • Valve Cover Gasket Replacement: A replacement gasket kit is extremely inexpensive and can usually be done with simple tools.
  • Seal Replacement: Crankshaft or camshaft seal replacement involves a longer job, but it’s a standard procedure.
  • Prevention Tip: Drive your car on synthetic oil and have it changed regularly.

✅ What We Do:

We inspect for oil leaks prior to offering any used Mitsubishi engine for sale and replace faulty seals or gaskets when required. We sell leak-free, pre-tested engines so you won’t be left with someone else’s problem. Mitsubishi engine problems

2. Overheating Issues

🚩 The Issue:

Overheating is commonly caused by:

  • Blockages within radiators
  • Faulty water pumps
  • Warped cylinder heads due to prior abuse

Late Mitsubishi engines are also highly susceptible to heat damage if cooling systems were bypassed.

🛠️ The Solution:

  • Drain and flush the cooling system and replace the radiator if plugged.
  • Replace the water pump and thermostat and check.
  • Compression test the engine to determine if the head has been warped or compromised parts.

✅ What We Do:

We check all of our engines for thermal efficiency and conduct a cooling system integrity test. If an engine shows signs of prior overheating damage, we don’t sell it—period. Mitsubishi engine problems

3. Low Compression in Cylinders

🚩 The Problem:

Compression loss in older Mitsubishi engines is caused by:

  • Worn piston rings
  • Cracked valves
  • Blown head gaskets

Symptoms include hard starting, poor acceleration, and increased oil consumption.

🛠️ The Fix:

  • Do a wet/dry compression test to find out the issue.
  • Head gaskets or valves replaced where needed.
  • Rebuild if the lower end is badly worn.

✅ What We Do:

Every one of our used Mitsubishi engines is compression and leak-down tested. Only those with strong, even compression in all of the cylinders are presented for sale. Mitsubishi engine problems

4. Timing Belt Failures

🚩 The Problem:

Most Mitsubishi engines, including the popular 4G63 engine, have a timing belt instead of a chain. Belts will break down or crack after a period and lead to destruction in the engine if the engine is interference-type.

🛠️ The Fix:

  • Replace timing belts at every 60,000 to 100,000 km.
  • Replace tensioner and water pump at service.

✅ What We Do:

Before shipping, we check the condition of the timing belt and replace it with a brand new OEM-spec belt if there is any sign of wear or aging. That’s our value-added inspection. Mitsubishi engine problems

5. Worn Engine Mounts

🚩 The Problem:

Engine mounts wear out with age and use, especially in turbo engines because of higher engine motion.

🛠️ The Repair:

  • Replace damaged mounts with OEM or improved polyurethane parts.
  • Check transmission mounts as well since these also wear simultaneously.

✅ What We Do:

Our sale mechanics inspect engine mounts and replace them if they exhibit even a trace of cracking, sagging, or excessive wear. Mitsubishi engine problems

6. Carbon Deposit in Intake or Valves

🚩 The Problem:

Sideline direct inject Mitsubishi engines like the 4B11T are more likely to carbon deposit, which destroys fuel economy and performance. Mitsubishi engine problems

🛠️ The Fix:

  • Do a walnut blasting on intake valves to clean out buildup.
  • Use fuel additives and routine maintenance.

✅ What We Do:

We completely clean out any intake system that has signs of excessive buildup. When necessary, we also replace re-used EGR components and injectors and clean them before selling the engine.

7. Excessive Engine Noise or Knocking

🚩 The Problem:

High-mileage older used engines may experience:

  • Rod knock
  • Lifter noise
  • Worn timing components

🛠️ The Fix:

  • Minor noise: engine treatment or high-mileage oil.
  • Rod knock: the engine must be rebuilt or replaced.

✅ What We Do:

Our engines undergo sound analysis and vibration testing. If it knocks, we don’t take it. We’re providing quiet, clean-sounding Mitsubishi engines, not bombs to time. Mitsubishi engine problems

8. Sensor Malfunctions (O2 Sensor, MAF, Knock Sensor)

Old sensors are too commonly neglected. An old Mitsubishi engine could have old sensors that result in:

  • Rough idling
  • Poor fuel economy
  • Check engine light (CEL)

🛠️ The Fix:

  • Replace defective sensors
  • Scan the ECU to clear codes after install

✅ What We Do:

We check for failing major sensors and only supply functioning parts with our used Mitsubishi engines. If a sensor shows failure, it is replaced before shipping. Mitsubishi engine problems

9. PCV System Failures and Oil Blow-By

🚩 The Problem:

PCV systems clog up, and there is too much pressure and oil blow-by into the intake.

🛠️ The Fix:

  • Replace PCV valve
  • Clean entire system up
  • Use an oil catch can on turbos

✅ What We Do:

Oil blow-by indicators are noted, cleaned, and tested again on engines. We make sure every engine departs with a functional PCV system. Mitsubishi engine problems

  • Frayed bearings
  • Shaft play
  • Oil leaking seals
