Information
O-ring cylinder base 102 x 2.
Fitted into the cylinder base sealing groove, the O-ring compresses between the cylinder and crankcase to form an oil-tight barrier that withstands temperature changes and engine vibration.
Sold each, 6 required per car.
Fits:
Porsche 964 Carrera 2 / Carrera 4 / RS / turbo 1989 - 1994
Porsche 993 Carrera 2 / Carrera 4 / Carrera S / Carrera 4S / turbo 1994 - 1997
Diagram ref no 2
This OE Match O-ring is manufactured to OE-equivalent dimensions and material properties to provide a reliable seal at the cylinder-to-case interface. Correct sealing here is essential to prevent oil seepage during heat cycles and maintain a clean, properly sealed engine during rebuild or maintenance work. Ideal for engine overhauls, reseals, or any time cylinders are removed, this direct-fit O-ring restores the original sealing function without modification.
Old O-rings can harden, flatten, or crack with age and heat, increasing the likelihood of oil seepage at the cylinder base. Replacing them during engine work helps ensure a proper reseal, reducing leaks and protecting surrounding components from oil contamination.
When to replace:
• During engine rebuilds or top-end work (cylinders removed)
• Any time cylinder bases are resealed
• Visible oil seepage at cylinder-to-case area
• High-mileage preventative reseal

Information
Cylinder head gasket.
OE Match cylinder head gasket (sealing ring) designed to seal the joint between the cylinder and cylinder head on air-cooled Porsche 964 and 993 engines, helping maintain proper compression and preventing leakage at the head-to-cylinder interface.
Sold each, 6 required per vehicle.
Fits:
Porsche 964 C2 / C4 / Carrera RS 1991-94
M 62M 06837 >>
M 62M 52758 >>
Porsche 964 Turbo 3.6L 1993 - 1994
Porsche 993 1995 - 1998
Diagram ref no 8
The gasket forms a critical seal at the combustion boundary where extreme heat and pressure are present. It helps keep combustion gases contained, supports stable compression, and prevents leakage that can lead to poor running, overheating, or costly engine damage.
Function:
• Seals the cylinder-to-head interface under high temperature and pressure
• Helps maintain compression and consistent combustion efficiency
• Reduces risk of blow-by and hot gas leakage at the sealing surface
• Supports long-term reliability during rebuilds or top-end refreshes
A compromised head gasket/sealing ring can cause compression loss and leakage at the head-to-cylinder joint, often showing up as poor performance, combustion leakage symptoms, and increased thermal stress. Replacing these gaskets during top-end work ensures correct sealing and protects freshly machined sealing surfaces.
When to replace:
• During top-end rebuild, head removal, or cylinder service
• Compression/leak-down results indicate sealing issues
• Evidence of leakage at head-to-cylinder interface
• Engine is apart and gaskets show wear, heat marking, or deformation
• Preventative replacement when refreshing 964/993 top end
