Passenger side coolant leak help/advice 2.7t

[dirtygrimace]

I am coming here to seek some guidance on what are some potential areas that would cause a leak on the passenger side from behind the alternator. Background : Car idles smooth and revs fine, this mostly came up from oil temp rising too high, not from car overheating, so it runs and drives but it runs the coolant tank empty I have only been testing it with car off at this point, and coolant will run right out the weep hole.I checked out some areas above and behind the car with a boroscope and couldn't see any water around the head gasket area. I want to get some ideas if there is a relief valve or something that maybe broke or lines that could possibly be causing this or if not thermostat.. Any advice would be greatly appreciated as I don't know where to go with this outside of pulling the engine which I would like to avoid.. This link goes to a video of what's going on, sorry for potato vertical camera shifted when I started it. https://youtu.be/I8JplQ1MhfY

Turbo coolant line or thermostat housing would be my guess.

my thoughts as well

Turbo feed line or the return? Like is it the inside of the thermostat housing?

Ok, so pulled off the front, the thermostat housing for checking, the piece seems to be intact. Pulled out the thermostat as well, used a house to route water through the tube that leads to the back side of the block.. By doing this I then received the leak out of the weep hole of the passenger side motor mount, but not when puttting water in the main channel. I looked around with a borescope and flashlight, no water leaking from the backside of the block I can see, and there is no water in the upper channels by the Aux pump.. down to just turbo coolant feed line.. and maybe the return line.. unless I can find a visual leak.. maybe just pull the engine at this point.. very frustrating... if anyone has any ideas I am open to places to look as pulling engine doesn't sound fun.

I doubt it is the turbo hose in the rear. I just got done replacing it and that would leak onto the back of the block or into the intake area. In my case I pulled the rubber portion if the hose off the metal part of the line and replaced with 3/8" (I think that was the size) silicone heater hose. This allowed me to skip pulling the motor. You maybe able to do something similar with the front lines.

I think the front/feed lines hook up at the middle of the head right above the motor mounts. This would explain it coming down on the motor mount.

Edit - the feed linea hook up right below the head in the middle of the block
