Product Information
Engine Cylinder Head Exhaust Valve.
Restore dependable engine performance with this OE Match Engine Cylinder Head Exhaust Valve, manufactured as a direct replacement. Produced to OE-style specifications, this exhaust valve is designed to control the release of combustion gases from the cylinder, maintaining efficient engine operation, correct compression, and reliable valve train performance.

Fits:
  • Porsche 911 1965-1968 2.0L / 912 SWB (F)
  • Porsche 356A 1955-59
  • Porsche 356B 1959-63
  • Porsche 356C 1963-65
  
Diagram Ref No 11

Exhaust valves operate under extreme temperatures and repeated combustion cycles, making them one of the most highly stressed components within the engine. Over time, heat, carbon deposits, corrosion, or insufficient lubrication can cause the valve face, stem, or seating surface to wear or burn, leading to poor sealing and reduced engine efficiency. Replacing worn or damaged exhaust valves restores proper combustion sealing and exhaust gas flow, making this OE Match component ideal for routine maintenance, engine repairs, rebuilds, and Porsche restoration projects.  

What This Product Does:
  • Controls the release of exhaust gases from the combustion chamber.
  • Maintains correct cylinder sealing during the combustion cycle.
  • Supports efficient engine performance and combustion.
  • Helps maintain correct compression and valve timing.
  • Restores proper exhaust gas flow.
  • Replaces worn, burnt, or damaged original exhaust valves.
  • Provides an OE-style fit and dependable quality.

Symptoms Of Wear Or Failure:
  • Loss of engine power.
  • Reduced engine compression.
  • Rough or uneven idle.
  • Engine misfires.
  • Excessive valve train noise.
  • Burnt, pitted, or cracked valve faces.
  • Increased exhaust emissions.
  • Excessive heat damage or carbon build-up on the valve.

Why Replacement Matters:

  • The exhaust valve plays a critical role in allowing spent combustion gases to exit the engine while maintaining an effective seal during compression and combustion. A worn, burnt, or damaged exhaust valve can reduce engine performance, lower compression, increase fuel consumption, and eventually cause serious engine damage if left unresolved.
  • Replacing the exhaust valve restores efficient exhaust gas flow, reliable cylinder sealing, and smooth engine operation while helping to protect other valve train components from unnecessary wear. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match engine cylinder head exhaust valve provides the correct fit, dependable quality, and long-lasting durability, making it an ideal choice for Porsche maintenance, engine rebuilds, repairs, and restoration projects.
