2017 1500 keeps blowing heater control valves

[Ofc1500]

I've replaced this damn heater control valve probably 6 times now in a year can't find any other issue but every couple of months it starts leaking. Anyone have any clue or had this issue? 68k miles

Also it's the v6.

OEM or aftermarket?
Have they all leaked from the same spot? Are they cracking?
Are you getting codes?
Are you topping up and bleading using the thermostat housing bleed screw after swapping the part?
