Need Help - coolant leak from where metal hardline meets thermostat housing!

Hi all!

As the title states, I have a pretty massive coolant leak coming from the middle port of the thermostat housing - a metal hardline that makes a left 90 degree turn. The hardline is secured with an o-ring inside the thermo housing and a t30 screw to the left of it holding it in place.

I just recently replaced the oil filter housing, oil cooler, and oil pan, so there's a solid chance that during one of these installations I bent that metal hardline in a way it didn't like. However I'm not entirely sure what I'm looking to replace here, the hardline or the thermo housing. The hardline seems like more of a PITA to do to be honest. I have a feeling that during the oil cooler installation I pried on the hardline too hard and either cracked the housing or moved the o-ring to a position that does not seal. Has anyone had any experience in this area? Had the car up on jack stands for 3 weeks now addressing various issues so I'd really like to get it dropped back on the ground asap.

Any advice is appreciated. Thanks in advance!
Frankie
