irregular tapping noises are not normal. Loud ones mean that camshafts and or small end bearings are on their way out.

Try using an oil additive (Forte's Top End treatment, for example) - it's very likely that you have sticky hydraulic tappets. If this solves the problem then have oil and filter changed ASAP. If it doesn't then you may need to consult a specialist.
