Our Recommendation
Our Recommendation
If you hear a brief rattling noise on cold start but have no engine management lights, a specialist tensioner replacement may prevent catastrophic failure. However, once cam/crank codes appear or metallic rattling persists, the risk of piston damage is high - on a Range Rover L405 LWB 5.0 Supercharged valued at £25,000-£45,000, a rebuilt engine with upgraded components offers better long-term value than repeated major repairs.

Range Rover L405 LWB 5.0 Supercharged Engine ReplacementFrequently Asked Questions
Question 1What are the warning signs of timing chain failure on a Range Rover L405 LWB 5.0 Supercharged-
