Cold-start chain noise
medium priorityWorth checking on: Some chain-driven engines
A brief sound needs professional diagnosis; it does not identify a failed chain by itself. Use it as a reason to seek evidence or an inspection.
Possible signs
- • Rattle immediately after a cold start
- • Irregular idle
Ask the seller
- • Can the engine be left cold for the viewing?
- • Is there evidence of chain or tensioner work?
At the viewing
- • Start it from cold
- • Stop if warning lights remain on
