Common failure points and repair options

Oil Filter Housing & Cooling System Vulnerability

Affected: Land Rover Defender 130 D350 (AJ20D6 / DT306, 2024-present)
Typical failure mileage: 30,000-60,000 miles (early production units)

Root cause

The oil filter housing, constructed from a specific plastic composite, can become brittle and crack under thermal stress, leading to sudden oil loss and potential engine seizure if not addressed.

Repair options

Repair tier	Dealer price	Specialist price
Preventative Oil Filter Housing Replacement	£800-£1,200	£500-£800
Full Replacement - rebuilt/reconditioned engine	£9,000-£14,000	£6,500-£10,000 [ESTIMATED]

Our recommendation

Proactive inspection and replacement of the oil filter housing is a highly recommended, low-cost preventative measure. If oil starvation has already occurred, a full rebuilt engine replacement is the safest and most reliable solution to protect your investment.
