* Engine variations: Even within the same model year, Toyota Corolla engines can have slight variations depending on trim level, transmission type, and even regional specifications.
* Maintenance information: The most accurate valve lash settings are always found in your car's owner's manual or a reputable workshop manual specifically for your 1983 Toyota Corolla 4-AC engine.
Where to find the correct information:
1. Owner's Manual: Check the manual that came with your vehicle. Look for a section on engine maintenance or specifications.
2. Toyota Service Manual: Obtain a workshop manual for your specific year, model, and engine. You can find these online or at auto parts stores.
3. Reputable Online Resources: Websites like Haynes, Chilton, or AllData may have repair information, but always double-check the accuracy and ensure it's for your specific engine.
Important Note: Incorrect valve lash settings can lead to engine damage. Always consult reliable sources and follow the manufacturer's recommendations.
