Womala Valve Cover Seal C2D3526 for Jaguar

Product Overview

The Spark Plug Tube Seal C2D3526 is a Genuine OE-grade sealing component for for Jaguar and for Land Rover vehicles with 3.0L V6 and 5.0L V8 petrol engines (AJ126 / AJ133). Also known as a spark plug hole gasket or valve cover washer seal, this seal fits into the valve cover around each spark plug tube, preventing engine oil from leaking into the spark plug wells . Over time, these rubber seals can harden and shrink due to heat cycling, allowing oil to contaminate the spark plugs and ignition coils . C2D3526 is the Jaguar part number; LR014345 is the Land Rover equivalent . Each seal is sold individually – quantity required depends on the engine (V6 requires 6, V8 requires 8) .

Land Rover Applications

⚠️ Important: This seal is specifically for petrol engines (3.0L V6 AJ126 and 5.0L V8 AJ133) . Not for diesel or 2.0L variants. This is the left-hand side seal – for right-hand side, a separate part number is required . Quantity required: V6 engines need 6 seals (3 per bank), V8 engines need 8 seals (4 per bank) .

Signs of Failure

• Oil in spark plug wells – visible oil around the spark plugs when ignition coils are removed

• Engine misfire – oil-contaminated spark plugs causing rough idle or misfire under load

• Check engine light – misfire-related DTCs

• Burning oil smell – from the engine bay

• Blue smoke from exhaust – oil entering the combustion chambers

💡 Spark plug tube seals are a common failure point on high-mileage AJ126 and AJ133 engines. If oil is present in the spark plug wells, the ignition coils and spark plugs should be inspected and replaced if contaminated .
