Why does my Audi 80's engine make a ticking sound?

I've noticed a ticking sound coming from my Audi 80's engine. It seems to be more noticeable at idle and gets louder when I accelerate. What could be causing this and how do I fix it?

It's possible that your engine is low on oil. Check the oil level and top it off if needed. This could also be a sign of a worn out oil pump, so it's best to get it checked by a mechanic.

Another possible cause could be a faulty lifter or valve. This could be due to wear and tear or lack of regular maintenance. It's important to have it inspected and replaced if necessary.
