How to fix a noisy valve lifter in an Audi 80?

I've been noticing a loud, repetitive ticking noise in the engine of my Audi 80. Upon further inspection, it seems to be coming from one of the valve lifters. Can anyone provide tips on how to fix this issue?

In order to fix a noisy valve lifter in an Audi 80, you will need to first pinpoint which lifter is causing the noise. This can be done by gently pressing down on each lifter with a screwdriver while the engine is running and listening for changes in the noise. Once identified, you can remove the camshaft and replace the faulty lifter. Remember to always use high quality replacement parts for optimal performance.
