Engine Mitsubishi 4G64 Reliability Factors
Durability and Longevity
I have seen the Engine Mitsubishi 4G64 prove itself time and again. This engine stands out for its ability to last well beyond 200,000 miles when I give it regular maintenance. Many drivers in commercial fleets report that their 4G64 engines run smoothly past 250,000 miles. I trust this engine because Mitsubishi built it with high manufacturing standards, using ISO-certified suppliers and pressure testing every unit.
The design has a long history, dating back to 1985. Over the years, Mitsubishi refined the engine, making it more robust. The 4G64 shares its block with the famous 4G63, but it features a taller deck height and a larger bore. These changes make it even more durable. I also appreciate how easy it is to find parts for this engine. Mitsubishi used it in many models, and even Hyundai and Chrysler licensed it. This widespread use means I can keep my engine running without breaking the bank.
Tip: If you want your engine to last, stick to regular oil changes and replace the timing belt on schedule.
Here’s a quick look at what makes this engine so durable:
| Factor | Explanation |
|---|---|
| Long production history | Produced since 1985, refined over decades |
| Robust design | Shares block with 4G63, improved for strength |
| Proven longevity | Exceeds 200,000 miles with proper care |
| Parts availability | Used in many models, parts are easy to find |
| Solid construction | Strong block, good lubrication, handles stress well |
| Positive owner reports | Praised for toughness in towing and off-road use |
Common Issues
Even the most reliable engines have their weak spots. I have noticed that the Engine Mitsubishi 4G64 sometimes struggles with starting, especially in cold weather. Some owners report persistent starting problems, even after repairs. Sensor faults, like issues with the MAF sensor or the ECU, can cause headaches. Timing belt failures also show up in owner reports, and these can lead to serious engine damage if not addressed quickly.
Here are the most common issues I have seen:
- Persistent starting problems, especially in cold weather
- Sensor faults, including MAF sensor and ECU resets
- Timing belt snapping, which can cause major engine damage
- High repair costs if problems are ignored
- Smokey starts and stalling when cold
- Sputtering or dying when the engine warms up
I always recommend replacing the timing belt every 60,000 miles and using high-quality oil. Regular maintenance helps me avoid most of these problems. I also watch for signs of wear, like ticking noises from the lifters or oil leaks. These can signal deeper issues, but I find that catching them early keeps my engine healthy.
Performance Over Time
I have driven the Engine Mitsubishi 4G64 for many years, and I am impressed by how well it holds up. After 50,000 miles, I still get strong performance, as long as I keep up with oil changes and tune-ups. I check for oil leaks from the valve cover gasket and replace the timing belt, water pump, spark plugs, and wires around 60,000 miles. These steps keep my engine running smoothly.
Owners often report engines with over 126,000 miles, and some even reach 200,000 miles or more without major issues. I have learned that preventive maintenance is the key. I check belts, fluids, brakes, and suspension regularly. I also listen for unusual noises, which can warn me about lifter or balance shaft bearing problems.
| Sign of Wear | Description | Cause/Effect |
|---|---|---|
| Balance Shaft Bearing Failure | Bearings wear out, can cause timing belt failure | Timing belt snapping leads to engine damage; needs regular oil changes |
| Timing Belt Failure | Belt-driven shafts rely on timing belt; failure is catastrophic | Replace every 60,000 miles; failure bends valves and damages engine |
| Lifter Failure | Ticking noise, reduced intake efficiency | Poor oil pressure; fix with better lubrication and upgraded lifters |
| Crankwalk Problem | Excessive crankshaft movement and vibration | Leads to rapid engine failure; common at high RPM |
I believe the Engine Mitsubishi 4G64 rewards those who take care of it. With regular attention, I can count on reliable performance for years.

Engine Mitsubishi 4G64 Maintenance and Costs
Routine Maintenance
I always stick to a strict maintenance schedule for my Engine Mitsubishi 4G64. Regular oil changes keep my engine running smoothly. I change the oil every 3,000 to 5,000 miles with conventional oil, or every 7,500 to 10,000 miles if I use synthetic. I never skip an annual oil change, even if I drive less. This prevents sludge and moisture buildup, which can ruin an engine.
I follow these steps to keep my engine in top shape:
- Replace the timing belt every 60,000 to 100,000 miles
- Change spark plugs every 15,000 miles (I prefer NGK copper plugs)
- Flush coolant and replace the thermostat
- Swap out spark wires and fuel filter
- Clean or replace the air filter
- Clean the MAF sensor
- Change transmission oil
- Flush power steering, brake, and clutch fluids every 2 to 3 years
Tip: I always use manufacturer-recommended oil types for better protection.
Repair Costs
I know that some repairs are more common than others. Valve stem seal replacement is usually affordable. Intake guides cost between $165 and $248, while exhaust guides run about $275 each. These repairs help my engine stay reliable without breaking the bank. I watch for signs of wear and fix problems early, which saves me money in the long run.
- Valve stem seal replacement: low cost
- Intake guides: $165–$248
- Exhaust guides: $275 each
Maximizing Engine Life
I believe regular maintenance is the secret to a long-lasting engine. Frequent oil changes prevent sludge, reduce friction, and keep my engine cool. I pay attention to driving conditions. Short trips, towing, and off-roading mean I change oil more often. I always choose synthetic blends when recommended. Professional oil changes include inspections that catch problems early.
| Aspect | Impact on Engine Longevity |
|---|---|
| Regular oil changes | Prevent sludge, reduce wear, extend engine life |
| Correct oil type | Enhances protection, reduces risk of overheating |
| Professional service | Early detection of issues, saves money on major repairs |
I trust my Engine Mitsubishi 4G64 to last for years because I never skip maintenance.
Engine Mitsubishi 4G64 vs. Other Engines
Comparison with Other Mitsubishi Engines
I have compared the 4G64 with other Mitsubishi engines like the 4G94 and 4G63T. I noticed that the 4G64 offers a great balance between cost and performance. When I look at maintenance and upgrade costs, the 4G64 sits right in the middle. The 4G94 is cheaper to buy and upgrade, but it does not match the power potential of the 4G64. The 4G63T is powerful, but it costs much more to maintain and upgrade. I want to show you a quick breakdown:
| Engine | Initial Cost | Upgrade Cost | Total Cost | Power Potential |
|---|---|---|---|---|
| 4G94 | $300–$800 | ~$2,500 | ~$3,300 | Up to 300hp |
| 4G64 | $400–$1,500 | ~$4,000 | ~$5,500 | 300–350hp |
| 4G63T | $2,000–$3,000 | ~$3,500 | ~$6,500 | 350hp+ |
I choose the 4G64 because it gives me strong performance without the high costs of the 4G63T. The longer connecting rods and larger bore help with durability and breathing. I do see that sourcing parts for upgrades can be more expensive, but the engine’s design makes it worth the investment.
Tip: If you want a reliable engine with good power, the 4G64 is a smart choice for most drivers.
Comparison with Competing Brands
I have owned engines from Toyota and Honda, so I know how they compare. Many people say Toyota and Honda engines are more reliable, and I agree that they often need less maintenance. Mitsubishi engines, including the 4G64, have a strong cast iron block and aluminum head, which help with durability. The 4G64 has lasted over 40 years in production, showing its reliability and strong aftermarket support.
- The 4G64’s longer rods reduce piston side-loading, which helps the engine last longer.
- The larger bore improves breathing and performance.
- Some issues, like crank walk and balance shaft failures, do happen. Toyota and Honda engines use timing chains, so they avoid these problems.
- I find that Mitsubishi engines need more attention, but proper maintenance keeps them running well.
- I get better value buying used Mitsubishi vehicles, even if resale value is lower.
I believe the 4G64 offers unique advantages in durability and performance. If you want a tough engine and do not mind regular maintenance, the 4G64 stands out against the competition.
I trust this engine to deliver reliable performance year after year. Regular maintenance keeps it running strong. I recommend this engine to anyone who wants peace of mind on the road.
Take care of your engine, and it will take care of you.
