Womala Intake Valve 1311281 for Land Rover Discovery 3 Discovery 4

Product Overview

The Intake Valve 1311281 is a Genuine OE-grade engine component engineered for the 2.7L and 3.0L V6 turbo diesel engines (276DT / 306DT / TDV6 / SDV6) in select for Land Rover and for Jaguar vehicles. Also known as an inlet valve, it controls the flow of air into the engine's cylinders, opening and closing at precise moments in the engine cycle to allow combustion air to enter the combustion chamber . JD61430 is the Jaguar equivalent part number; LR008130 is the Land Rover service kit reference for a complete valve set .

Key Features

• OE-grade quality – manufactured to original equipment specifications; made in Czech Republic (Genuine Land Rover) 

• Chrome-silicon steel construction – hardened tip, chromed stem for durability and wear resistance 

• 45° valve seat angle – factory-spec sealing surface

• Precision dimensions – 97mm length, 5.94mm stem diameter, 27.8mm head diameter 

• Quantity required – 24 valves per engine (4 valves per cylinder × 6 cylinders); available individually or as a set 

OE Cross-Reference

💡 Note: LR008130 is the Land Rover service kit reference for a complete intake valve set. JD61428 is the exhaust valve equivalent; JD61430 is the intake valve .

Vehicle Fitment

Engine codes: 276DT (2.7L V6) · 306DT (3.0L V6) 

⚠️ Important: This intake valve is specifically for 2.7L and 3.0L V6 turbo diesel engines (276DT / 306DT) – not for petrol, V8, or Ingenium variants. 24 valves required per engine (4 per cylinder).

Signs of Failure

• Engine misfires – faulty valve may not seal properly, causing incomplete combustion, rough idle, or hesitation when accelerating 

• Loss of power & poor acceleration – inefficient air intake reduces engine output; vehicle may feel sluggish or struggle on inclines 

• Backfiring or popping sounds – improper sealing can cause fuel-air mixture to ignite in the intake manifold 

• Excessive oil consumption – worn valve guides allowing oil into the combustion chamber

• Compression loss – poor valve sealing reducing cylinder pressure

💡 Valve failure is often caused by worn valve guides or seats, carbon buildup, or timing issues. Replacement is typically performed during cylinder head service.

Critical – Verify Your VIN Before Ordering

Intake valves are VIN‑ and engine‑specific. Confirm your vehicle's engine code (276DT vs. 306DT) and quantity required (24 per engine). Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation required – cylinder head removal is necessary. Replace all valves, valve stem seals, and guides as a set when performing a valve job. Check valve clearance and perform a compression test after installation.
