Information
Exhaust valve, (Sodium-filled).
This is a sodium-filled exhaust valve designed to Porsche’s original specifications, as used in 964 Carrera (C2 / C4) 3.6L engines (1990–94). The sodium fill helps dissipate heat from the valve head into the valve stem, improving thermal management under exhaust conditions.
Sold each, 6 required per car.
Fits:
Porsche 964 Carrera 2 / Carrera 4 3.6L 1989 - 1994 (M64.01 / M64.02)
Porsche 964 RS Carrera 3.6L 1991 - 1994 (M96.03)
Diagram Ref No 12.
What exhaust valve does:
• Seals the combustion chamber on the exhaust side, opening and closing at the correct times to allow exhaust gases to exit
• The internal sodium enhances heat transfer, reducing valve temperature, helping prevent distortion or burning
• Works in tandem with valve springs, guides, and seats to maintain consistent cylinder head performance
Over time, exhaust valves undergo extreme heat cycles, which can lead to wear, bending, warping, or pitting on the sealing face. A faulty or damaged exhaust valve can lead to compression loss, misfires, reduced power, excessive smoking, or engine damage. Replacement improves reliability, restores engine efficiency, and ensures long life under high temperature conditions
• It fits in the cylinder head’s exhaust valve seat for Porsche 964 the exhaust port side of each combustion chamber
• The valve stem goes through the valve guide in the head, and the head of the valve seals against the exhaust seat when closed, with its tip actuated by the rocker or cam mechanism.
