Where is the number 1 piston on 1.6 liter Chevy chevette?

On a 1.6L Chevy Chevette engine (typically an inline-four), the number 1 piston is located at the front of the engine, on the driver's side (when viewed from the front of the vehicle). However, always double-check your specific engine's markings as there might be minor variations. Look for casting marks on the engine block itself – they'll usually clearly indicate cylinder number 1.
