Womala Valve Stem Seal LR054369 Valve Spring Seat for Land Rover Range Rover Discovery 4

Product Overview

The Valve Stem Seal LR054369 is a Genuine OE-grade engine sealing component for 3.0L V6 and 5.0L V8 petrol engines (AJ126 / AJ133) in select for Land Rover and for Jaguar vehicles. This precision seal fits at the top of the valve guide beneath the valve spring, controlling the oil film on the valve stem and preventing engine oil from being drawn into the combustion chamber or exhaust port. LR078819 is the current replacement part, superseding LR054369, LR010753, AJ811473, and AJ813623.

Key Features

• Controls oil consumption – seals the valve guide to prevent oil entering the combustion chamber

• OE-grade quality – manufactured to original equipment specifications

• Direct-fit replacement – matches factory valve guide dimensions

• For 3.0L V6 & 5.0L V8 petrol engines – AJ126 / AJ133 engine families

• Quantity required – 24 seals for V6 (4 per cylinder); 32 seals for V8 (4 per cylinder)

OE Cross-Reference

💡 Supersession Note: LR078819 is the current replacement part, superseding LR054369 and LR010753 for 5.0L V8 applications. AJ811473 and AJ813623 are Jaguar equivalents for the same seal.

Vehicle Fitment

⚠️ Important: This valve stem seal is specifically for petrol engines (AJ126 / AJ133) – not for diesel variants. Diesel engines use a different seal (1311285).

Signs of Failure

• Excessive oil consumption – oil being drawn past worn seals into the combustion chamber

• Blue smoke from exhaust – especially on start-up or after idling

• Fouled spark plugs – oil contamination causing misfires

• Engine performance issues – rough running or loss of power

💡 Valve stem seals typically need replacement during cylinder head work or valve spring service. Worn seals are a common cause of oil consumption on higher-mileage AJ126/AJ133 engines.

Critical – Verify Your VIN Before Ordering

Valve stem seals are engine‑specific. Quantity required: 24 for V6, 32 for V8. Provide your VIN – our team confirms exact compatibility and correct quantity before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation required – cylinder head or valve spring removal is necessary. Replace all seals for the affected cylinder bank when performing this service. Use a proper valve spring compressor and seal installation tool.
