Engines with high failure rates 

• 6.0L and 6.4L Power Stroke diesel engines: These engines (2003-2007 and 2008-2010, respectively) are notorious for expensive problems, including head gasket failures, injector issues, and turbocharger failures. 
• 5.4L Triton V8: This engine (1997-2010) is infamous for spark plugs breaking during removal and cam phaser/timing chain issues. 
• 3.8L SX V6: From 1982 to 2008, this engine had issues with weak head bolts causing head gasket failures, and early versions were prone to coolant leaks.

Problematic EcoBoost engines

• 1.0L EcoBoost (early versions): Early models used a rubber timing belt in hot engine oil, which could degrade and clog the oil pickup, leading to oil starvation and engine damage. 
• 1.6L EcoBoost: This engine has been associated with overheating and coolant leaks. 
• 3.5L EcoBoost: Problems can include carbon buildup, premature timing chain wear, and water pump failures. 
• 2.7L EcoBoost: Early models (around 2016-2017) experienced issues with defective valve guides, excessive oil consumption, and leaking plastic oil pans.

How long do Ford 5.0 engines last?

A Ford 5.0L Coyote engine can have a life expectancy of 200,000 to 300,000 miles or more with proper maintenance, but this varies depending on factors like driving conditions and service history. Some well-maintained engines have exceeded 400,000 miles. Consistent oil changes, timely replacements of worn parts, and other regular maintenance are crucial for maximizing the engine's longevity.

Factors influencing engine life expectancy

• Maintenance: Regular oil changes and other scheduled maintenance are the most critical factors. 
• Driving habits: Driving the vehicle hard or using it for heavy towing can increase wear and tear. 
• Component care: Addressing issues like oil consumption or minor problems promptly can prevent major damage. 
• Part quality: Using high-quality replacement parts can help maintain the engine's performance and longevity. 

What to expect with proper care

• 200,000-300,000 miles: This is the expected lifespan with proper maintenance. 
• Over 400,000 miles: Some engines have reached this milestone, particularly those with meticulous care and original parts, as shown by anecdotal evidence from owners. 
• Performance over time: With age, components like timing chains or cam phasers may need replacement, even if the engine is still running well. 
• Potential issues: Common problems include overheating, engine misfires, oil leaks, or cylinder head gasket failure. Addressing these promptly can prevent more severe damage. 

What is Ford's most reliable V8?

The most reliable modern Ford V8 is generally considered to be the 5.0L "Coyote" V8 due to its simpler design, while for heavy-duty trucks, the 7.3L "Godzilla" V8 is highly reliable. Historically, older V8s like the 5.0L "302" from the 1980s and the 4.6L Modular V8 have also built reputations for longevity.
