1. Drain the engine oil. 2. Remove the oil pan (FIG 1). The oil pan has to be removed for the following reasons: The timing chain cover cannot be removed without removing the oil pan first. This is because of the two dowel pins on each side of the timing chain cover that mesh with the oil pan. See FIG 1-B. I seen 1.6 crdi with 30.000km and 1.6 crdi with 315.000km+. Both have this sliding chain noise and they have it for a long time, and for a long time this noise is not changing to higher sounds like chain rattling from first video. CRDI timing system is "noise free" few thousand km from when is brand new. 27jSZv.
