Checked the air vent is slacked off, The lockshield valve has an outer collar, you probably new that a radiator key is too small. I don’t want to damage the outer brass collar anymore, it’s already slightly bent. I’ve order a 4 way utility key that comes today. Can you tell me, If adjusting this valve stops the noise, can I leave this lockshield valve like that long term ? Or is this a temporary solution, in which we need a ABV installed going forward? Typically it hasn’t vibrated/ droned much in the short time I’ve been at home this week; but I’m here home most of tomorrow, with my new 4 way key!
Vibrating/ droning sound since new hot water cylinder was installed.

Yes, no problem.
A ABV installation is still recommended even if the boiler (like yours?) has a internal one, to cool down the boiler heat exchanger but if there is no banging/noise from the boiler on pump overrun when it shuts down without it, maybe leave it.
