Technical Specifications

Vehicle Fitment

⚠️ 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 — the right-hand side uses a separate part number (C2D3527 / LR014346).

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.
