Odd V8 coolant leak - any advice?

I’ve had a few coolant leaks on my V8. I had a cracked thermostat housing; easy fix at $40. Then the the thermostat body sprung a leak. $140 for that. Now I have a new leak from a different part. I’ve taken pics using UV light. The leak appears to be at the union of the parts shown, definitely the upper join and possibly the lower also. Pics should make sense.

Can anyone advise if there’s a gasket here that may have failed or anything else to try?

That's a leak from the EGR cooler. You'll have to take off the EGR and examine the body of the cooler section to see where the leak is. Worst case scenario, there'll be a crack in the cooler or the inlet or outlet pipes and you'll need a new EGR Part Nº 4536857. About £244.00
