Womala Automatic Transmission O Ring 30751874 Transmission Seal for Volvo XC40

Core Functions

• Oil Leak Prevention: It forms a tight seal between the valve cover and the cylinder head, stopping engine oil from leaking onto hot engine parts like exhaust manifolds (where it could burn and make smoke) or onto the ground. This prevents oil loss and possible engine damage.
• Contaminant Blocking: It keeps external dirt, dust, and debris from entering the valve cover and polluting the valvetrain. If the oil gets contaminated, it would speed up the wear on camshafts, valves, and lifters, shortening the engine's lifespan.
• Auxiliary Sealing (for sets): The set includes extra seals like spark plug tube seals to stop oil from seeping into spark plug wells. This avoids misfires caused by spark plugs contaminated with oil and protects ignition parts.

Notes: Valve cover gaskets are engine-specific (for example, 4-cylinder vs. 6-cylinder) even for the same model. For 100% fitment accuracy, confirm compatibility with your vehicle’s engine displacement and valve cover design via its VIN (Vehicle Identification Number) or consult Volvo’s official service manual. Additionally, check if the set includes all required auxiliary seals for your specific application.
