Engine noise

[Brucey89]

2010 pegeout partner making a popping/tapping sound from engine. Goes away once engine has warned up and driving. Any ideas?

Oil pressure when cold - when was the oil last changed (and how frequently has it been changed), and additionally, the oil filter changes?

Has it always sounded like this, or is it a sudden recent thing?

Injectors can be noisy when on a cold start.

Last oil change about 18 months ago, van has only done 3500 miles since last service. Been doing it the oast week but seems to be getting louder.
