So I ran out of oil and after 4 days of it being delivered and working just fine, my boiler is now showing the lockout light and the rest buttons aren't working. I can't locate the bleed valve, how tf do I bleed the air out of the system? Help! The boiler is a Worcester Greenstar heatslave 12/18

You look to have a 2 pipe oil system which probably means you have a tiger loop system.
If so chances are it's not air locked.
As you have run out of oil blocked filter/oil line possible.
Your oil hoses need changing urgently I would suggest a competent oil engineer required.
