What is a common cause of oil leaks in the Audi 80 engine?

I've noticed some oil stains on my garage floor from my Audi 80. What is the most likely source of the leak and how can I fix it?

A common cause of oil leaks in Audi 80 engines is a faulty valve cover gasket. This gasket can wear out over time and cause oil to leak out.

Another possible cause of oil leaks in Audi 80 engines is a cracked or damaged oil pan. This can happen from hitting a curb or road debris, and the only solution is to replace the oil pan.

Check the oil filter for any leaks as well. It may need to be tightened or replaced to stop the leak.
