What are common engine issues in the Audi 80?

I recently bought a used Audi 80 and noticed some strange noises coming from the engine. I want to know about the common engine issues in this model so I can take preventative measures.

The most common engine issue in the Audi 80 is a faulty oil pump, which can lead to engine failure if not addressed promptly. It is recommended to check the oil pump regularly and replace it as needed.

Another common issue is a leaky valve cover gasket, which can cause oil to leak onto the exhaust manifold and create smoke. It is important to replace the gasket to prevent potential fire hazards.
