Power Stroke Diesel Engines: Complete Guide to Ford's 6.0L, 6.4L & 6.7L

Ford's Power Stroke Diesel Legacy

Ford's Power Stroke diesel engines have powered Super Duty trucks for over two decades. While some generations had serious issues, the modern 6.7L Power Stroke has redeemed Ford's diesel reputation. Understanding which Power Stroke to choose is critical when replacing your diesel engine.

At Used Engines Store, we specialize in Power Stroke diesel engines and know which generations to recommend and which to avoid. Here's your complete guide to Ford Power Stroke diesel engines.

Power Stroke Engine Generations

6.0L Power Stroke (2003-2007) - Avoid Unless Bulletproofed

  • Power: 325-350 hp
  • Torque: 560-650 lb-ft
  • Common issues: EGR cooler failures, head gaskets, oil cooler, FICM, injectors
  • Reputation: Notorious reliability problems, expensive repairs
  • Cost to bulletproof: $5,000-$8,000

6.4L Power Stroke (2008-2010) - Avoid Completely

  • Power: 350-390 hp
  • Torque: 650-735 lb-ft
  • Common issues: Cracked pistons, turbo failures, DPF problems, fuel dilution
  • Reputation: Worst Power Stroke ever made
  • Our advice: Don't buy, even cheap

6.7L Power Stroke (2011-2019) - The Redemption

  • Power: 390-450 hp
  • Torque: 735-935 lb-ft
  • Common issues: CP4 fuel pump (2011-2016), turbo failures (minor)
  • Reputation: Finally reliable, competitive with Cummins/Duramax

6.7L Power Stroke (2020-Present) - Best Ever

  • Power: 475-500 hp
  • Torque: 1,050-1,200 lb-ft
  • Common issues: Too new to determine
  • Reputation: Best Power Stroke ever, rivals all competitors

Why 6.0L and 6.4L Failed

6.0L Problems: EGR cooler failures, head gasket issues, oil cooler failures, FICM problems, injector failures. Total bulletproofing cost: $5,000-$8,000.

6.4L Problems: Cracked pistons, twin turbo failures, DPF issues, fuel dilution. No fix available - avoid completely.

6.7L Power Stroke: Ford's Success

Why it's better:

  • ✅ In-house Ford design (not International)
  • ✅ Stronger CGI block and internals
  • ✅ Reverse-flow heads for better cooling
  • ✅ 200,000-300,000+ mile lifespan
  • ✅ Competitive reliability with Cummins/Duramax

Common 6.7L issues (minor):

  • CP4 fuel pump failures (2011-2016) - $8,000-$12,000 to fix
  • Turbo failures - $2,000-$4,000
  • EGR cooler issues - $800-$1,500

Best Power Stroke to Buy

Best choice: 6.7L (2017+) - Fixed CP4 issue, proven reliability

Good choice: 6.7L (2011-2016) - Consider CP3 conversion

Avoid: 6.0L unless fully bulletproofed

Never buy: 6.4L - worst diesel ever made

Cost Comparison

Example: 2015 F-250 with 6.7L Power Stroke failure

New from Ford: $15,000-$20,000 total

Remanufactured: $11,000-$15,000 total

Used (Used Engines Store): $9,000-$13,000 total

Savings: $6,000-$7,000 vs new
