Symptoms
A rattle for a second or two on a cold start, later joined by cam-timing codes P0016, P0017, P0018 or P0019.
The fix, step by step
- Lock the engine at the correct position with the JLR timing tools before anything comes apart.
- Replace both cam chains, the tensioners and blades, both guides, the auxiliary drive chain with its tensioner and guide, and the cam lubricating jets, then refit with new rocker-cover gaskets and spark-plug seals.
- Don't reuse old tensioners or guides: reusing tired parts is the shortcut that brings the truck back on a hook.
