Worcestor Danesmoor 15/19 leaking above bleeder

Hi

Boiler guy came for service and put a new jet in but we now have a bad smell, I can see a steady oil leak from the Allen socket screw above the bleed valve. Its loose, whats that for please? I can feel its on a spring so I guess not something I can just tighten up?

I called him, no reply as yet.

Sounds like its the pressure screw and I need a new pump.

Can we have a picture of the leaking screw please?

It’s a Danfoss MSLB032. Plumbers merchant don’t seem to recognise it so don’t know the replacement.
