How to properly adjust the valves on an Audi 80?

I recently purchased a used Audi 80 and have noticed some valve noise. I was wondering how can I properly adjust the valves on my car to ensure optimal engine performance?

To properly adjust the valves on an Audi 80, you will need a feeler gauge, a proper tool to adjust the valves, and a good understanding of engine mechanics. Start by setting the engine at its proper idle speed and remove the valve covers to access the valves. Use the feeler gauge to check the valve clearance and adjust as needed. It may take some trial and error to get it just right, so be patient and take your time.
