The Seal Ring, cylinder head cover bolt (32145) seals combustion, oil, and coolant passages between head and block. Replacing it with Porza quality restores compression and prevents engine damage.
A seal ring for a cylinder head cover bolt is a sealing component placed under or around the bolt that secures the valve cover. Its function is to prevent engine oil leaks around the bolt area and maintain a tight seal of the cylinder head cover.
Key specifications include inner and outer diameter, thickness, material (such as oil-resistant rubber or elastomer), temperature resistance, and compatibility with the engine. It must withstand heat, oil exposure, and pressure variations.
Replacement is necessary when the seal is worn, hardened, cracked, or leaking. It is also recommended to replace it during valve cover gasket service or engine maintenance.
Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.
Porza provides high-quality engine sealing components with fast delivery across Europe and options for online ordering or in-store pickup.
If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
