Camshaft seal Honda OEM 27x43x9 91203-PFB-013

Honda OEM camshaft seal 91203-PFB-013 is a genuine 27×43×9 mm cam seal used across many classic Honda engines. It seals the end of the camshaft at the cylinder head, preventing oil leaks from the camshaft area and ensuring clean, reliable engine operation.

This seal is used in both DOHC and SOHC engines:
– in DOHC engines (dual cam), the engine requires 2 seals — one for each camshaft,
– in SOHC engines (single cam), the engine uses 1 seal.

Why choose the original Honda camshaft seal?

• Exact OEM dimensions – perfect fit for 27×43×9 mm camshaft housings.
• Oil- and heat-resistant rubber designed specifically for camshaft rotation speed and temperature.
• Durable spring-loaded lip for long-term sealing performance.
• Replaces multiple discontinued OEM references.
• No modification required — drop-in fit exactly as original.

Symptoms of a worn camshaft seal

• oil leaking from the front of the cylinder head,
• oil on timing belt covers or around the cam sprocket,
• burnt oil smell from oil dripping onto hot components,
• unexplained oil loss with no other visible leaks.

Driving with a leaking cam seal can contaminate the timing belt with oil, which may reduce belt life and increase the risk of damage.

FAQ – Camshaft Seal 91203-PFB-013

How many seals does my engine need?
– DOHC engines require 2 seals,
– SOHC engines require 1 seal.

Does 91203-PFB-013 fit all B20 and D16 engines?
It fits many listed variants (B20A2/A5/A7/A8, B20B/Z, D16A3/A8/A9/Z5, ZC1), but not every single sub-version. Because Honda changed head designs across markets and years, verifying compatibility by VIN is recommended.

How is the OEM seal different from cheap aftermarket replacements?
OEM seals have the correct rubber hardness, moly-lip profile and spring tension. Many cheap aftermarket seals harden quickly, leak prematurely or have slight dimensional errors causing improper sealing.

Do I need to use silicone during installation?
No. A camshaft seal must be installed dry in a clean bore. Using silicone can prevent proper seating and may cause leaks.

Which way does the seal face?
The side with the visible spring must face toward the oil (inside the engine). This ensures correct lip pressure and long-term sealing.
