⚙️ WHAT THIS PART DOES - CRITICAL ENGINE COMPONENT

This small but vital O-ring gasket is a crucial component in your Subaru's turbocharged engine system. It serves as the primary seal for the turbocharger bypass valve (BPV), also known as the blow-off valve.

🔒 Pressure Seal

Creates an airtight seal between the bypass valve and intercooler system

🎯 Boost Control

Maintains proper boost pressure regulation during throttle transitions

🛡️ System Protection

Prevents boost leaks and protects turbocharger from damage

⚠️ WHY YOU NEED THIS PART - SYMPTOMS OF FAILURE

🔍 Common Warning Signs:

  • Audible boost leaks (hissing sounds)
  • Loss of turbo boost pressure
  • Poor throttle response
  • Check engine light activation
  • Increased fuel consumption
  • Turbo flutter or surge

💥 Consequences of Ignoring:

  • Reduced engine power and torque
  • Poor fuel economy
  • Potential turbocharger damage
  • Engine management complications
  • Failed emissions testing

🔄 HOW THE TURBOCHARGER BYPASS VALVE SYSTEM WORKS

1
Boost Building

Turbocharger compresses air through intercooler to engine

2
Throttle Closure

Throttle body closes, creating high-pressure wall

3
Pressure Relief

Bypass valve opens to relieve pressure

4
Air Recirculation

Pressurized air redirected back to intake system

🎯 The O-ring (Part #22656AA020) seals the connection between the bypass valve and intercooler piping, ensuring no boost pressure escapes during this critical process.

📍 SYSTEM LOCATION & INSTALLATION

Component Connections:

  • Intercooler outlet piping (high-pressure side)
  • Bypass valve assembly (mounted on intercooler or piping)
  • Recirculation line (returns to turbo inlet)
🔧 Installation Recommendations:
  • Professional installation recommended for optimal results
  • Replace during bypass valve service or when boost leaks detected
  • Use genuine Subaru assembly lube for proper installation
  • Follow torque specifications to prevent damage
