Timing Chain Stretch (Lower Chain Guide/Tensioner Wear)
Engine · severity: High if undetected - the failure mechanism (lower chain guide/tensioner wears, chain stretches, eventually jumps a tooth on the sprocket) can progress to valve/piston contact, requiring an engine rebuild or replacement. · confidence: 68/100 · 4 cited sources
Symptoms to watch for
- Rattling or chain noise from the front of the engine, often most noticeable on cold start
- In advanced cases, rough running or a sudden loss of power if the chain has begun to jump timing
- Engine warning light in advanced cases
What to check before you buy
- Listen for chain rattle on a genuine cold start - a warmed-up test drive at a dealer or by a seller who started the car in advance can mask this
- A workshop can check chain stretch directly against the manufacturer's measurement procedure
- No specific fault code is documented for this issue - do not expect a clean DTC to confirm it; diagnosis relies on noise and direct mechanical inspection
