How urgent is timing chain rattle?
A cold-start rattle that clears after 5–10 seconds means the tensioner is losing pressure overnight — replace the timing chain kit within 2 weeks before the chain jumps timing (catastrophic engine damage costing ₹1,50,000–₹3,00,000). Continuous rattle means immediate stop and tow. GarageNation has done 500+ timing chain kits for BMW N20, VW EA888, Mercedes M271/M274, and Maruti K-Series.
