Symptoms: Engine rattle, especially on start-up, power loss and misfires (P0300 to P0304).

Check for the garage: Listen to a cold start, read misfire codes, look for the yellow mark on the timing cover (Astra H) and check chain stretch.
Cost cited in the source: Chain: approx. €650–1,400 (converted from dollars); re-torquing the bearing blocks: far lessA rough figure from the original database, not an up-to-date quote.
