Land Rover Range Rover Valve Cover PCV Diaphragm - LR041443

A diaphragm in the Range Rover valve cover forms part of crankcase ventilation. As it wears, cracks or breaks, air not measured by the airflow meter can enter the system, with unstable idle, whistling from the cover or increased oil consumption.

Vehicle Applications

• Land Rover / Range Rover valve cover applications identified by the references below.
• The 5.0 engine uses 2 diaphragms; the 3.0 engine uses 1 diaphragm.

Cover Selection and Quantity

The diaphragm is listed for valve covers LR041443, LR010780, LR113201, LR041684, C2Z29186, AJ814002 and T2R93535. The quantities of two and one above describe engine requirements, not a confirmed package quantity.

When to Inspect This Diaphragm

• Oil leakage or seepage around the valve cover.
• Burning oil smell after the engine has warmed up.
• Unmetered air entering through the cover or crankcase ventilation system.
• Unstable engine idle.
• Increased oil consumption.
• Whistling, abnormal vacuum or mixture faults associated with loss of sealing.
• Increased effort to open the oil filler cap with the engine running.
• Engine oil leakage associated with damage to engine seals.

These symptoms call for inspection of the relevant system; they do not confirm this diaphragm as the cause on their own.

Repair Scope

Replacing the worn diaphragm separately avoids replacing a serviceable valve cover. Inspect the cover, oil separator housing and ventilation hoses for cracks or damage. A damaged housing may require more than a diaphragm replacement.

Important Before Ordering

Compare the installed assembly reference, diaphragm design and any stated dimensions before ordering. Check the housing and ventilation hoses for damage.

FAQ

How many diaphragms does the 5.0 engine use?

The 5.0 engine uses 2 diaphragms. This is the engine requirement, not a statement of the quantity supplied in a package.

How many diaphragms does the 3.0 engine use?

The 3.0 engine uses 1 diaphragm.

Which cover references can I compare first?

The listed cover references include LR041443, LR010780, LR113201, LR041684, C2Z29186, AJ814002 and T2R93535.

Does a difficult-to-open oil filler cap warrant inspection?

Increased opening effort with the engine running is one of the described signs of a damaged cover diaphragm. Inspect the diaphragm and crankcase ventilation system rather than treating this sign alone as a diagnosis.
