Need to replace cam chain tensioners and chains on a Land Rover Discovery 4 3.0 TDV6 without removing camshafts, but previous mechanic replaced only timing belts, not chains, causing tapping noise.

No clear documentation or guide on whether camshaft removal is required for this specific engine chain replacement; existing repair procedures may be overly complex or incomplete.
