Information
Chain housing O-ring, 6 x 2.5 mm
This original Porsche O-ring is used in the chain housing / oil bridge sealing area, helping prevent oil leaks and maintain correct sealing around the timing chain housing assembly.
Sold individually
Fits:
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998
Diagram ref no 22
What This Part Does / Functions
• Seals the chain housing / oil bridge connection
• Helps prevent engine oil leaks
• Supports correct sealing around the timing chain housing area
• Helps maintain clean and reliable engine operation
• Replaces a hardened, flattened, cut or leaking original O-ring
• Provides correct OE Porsche size, material and fitment
• Supports correct reassembly after chain housing or oil bridge service
• Helps maintain factory engine sealing performance.
Why Replace This Part?
O-rings are exposed to engine oil, heat, pressure and age-related hardening. Over time, the seal can flatten, crack, swell or lose elasticity. Once the chain housing or oil bridge area has been disturbed, the O-ring should normally be replaced to ensure a reliable seal when reassembled. Replacing it with a Genuine Porsche OE chain housing O-ring helps prevent oil leaks and supports correct engine sealing.
Common Symptoms of a Failed Chain Housing O-Ring
• Oil leak around the chain housing area
• Oil residue near the oil bridge or chain tensioner area
• Persistent seepage after previous engine work
• Hardened, flattened or cracked O-ring during inspection
• Oil smell from hot engine components
• Oil drips underneath the vehicle
• Seal damage after chain housing service
• Need to reseal the oil bridge / chain housing connection.
When to Replace This Part
• When removing or refitting the chain housing components
• During chain housing, oil bridge or chain tensioner service
• If oil leakage is traced to the chain housing sealing area
• If the O-ring is hardened, flattened, cracked or damaged
• During engine rebuild or top-end repair
• When replacing related timing chain housing sealing components
• After separating the oil bridge from the chain housing
Where It Fits on the Car
This O-ring fits in the engine chain housing / oil bridge sealing area. It is used around the timing chain housing system on the flat-six engine and helps seal the oil passage connection where specified. Correct installation is important. The sealing surfaces should be clean, and the O-ring should be fitted without twisting, pinching or damage.
