* 1.0L 3-cylinder: This was the most likely engine. The timing specification will be in your owner's manual or a repair manual specific to that year and engine. It's typically expressed in degrees Before Top Dead Center (BTDC).
* 1.3L 4-cylinder: Less common, but possible. Again, you need a repair manual specific to this engine and year to find the correct timing.
To find the correct timing:
1. Identify your engine: Look for an engine code or displacement (1.0L or 1.3L) on an engine sticker or in your vehicle's paperwork.
2. Consult a repair manual: A Haynes or Chilton repair manual for your specific 1988 Chevy Metro will have the precise timing specifications for your engine. This is the most reliable source.
3. Use a timing light: You'll need a timing light to actually set the timing. The repair manual will show you where to connect the timing light and how to interpret the markings on your engine's timing pulley.
Without knowing the specific engine, I cannot give you the correct timing. Attempting to set the timing without the correct information could damage your engine.
