It sounds like you may have a problem with your valve lifters. They could be sticking or worn out, causing the clicking noise. I suggest taking it to a trusted mechanic to have them inspected and potentially replaced.

One possible cause of the clicking noise could be low engine oil. Check your oil levels and if they are low, top them up. If the noise persists, you may also want to get your oil filter checked and changed if needed.

Another potential culprit could be a loose or damaged timing chain. This is a more serious issue and should be addressed by a professional mechanic as soon as possible to avoid further damage to your engine.
