JLR 204DTD ENGINES
The JLR 204dtd (2.0 Ingenium diesel) engine has a known issue with premature timing chain wear, which can lead to a cold start rattle and, if left unaddressed, catastrophic engine damage. This is caused by factors like weak materials, chain stretch, and poor tension, often exacerbated by oil dilution and long service intervals. Symptoms can include a rattling noise, misfires, loss of power, and a check engine light. To mitigate this, regular oil changes and prompt attention to any rattling are crucial. A full replacement of the timing chain, tensioners and guides is the recommended solution once symptoms appear.

We replace the timing chain, tensioners and guides on these engines on a regular basis on the various Land Rover and Jaguar models that are affected. This also includes engine oil and oil filter replacement as part of the process.
