What should I do if my Audi 80's engine starts making strange noises?

I've noticed that my Audi 80's engine has been making unusual sounds lately. What could be causing this and what steps should I take to address it?

It could be a sign of a worn out bearing or a faulty valve. I would recommend taking your car to a trusted mechanic as soon as possible to avoid any potential damage to the engine.

It's possible that the issue is with the oil pump or the timing belt. I would suggest getting your car checked by a professional to determine the exact cause of the noise.
