Exclamation Coolant leak. Can't figure out source. Pics inside

I have a decent coolant leak going on right now (1/2 gallon every 2k miles).

Water pump recently replaced.

I looked at all the hoses I could easily see from above and below the car. I can't find a source. There is nothing suspicious around the water pump.

The main accumulation of coolant is to the rear of the water pump near the downpipes and engine mount. I can't see the source which makes me think it is probably going to end up being around the engine supply coolant pipe.

I see there is a DIY for this. Anyone had this replaced by an independent shop? Looks a little more involved than what I am willing to do. I'm worried this is going to be a $500+ repair for a $4 gasket.

You can see coolant accumulating on the oil inlet pipes for the rear turbo (two shorts arrows).

Here's the best picture I could find when I did my turbos's but anyways..Theirs the obvious coolant lines to/from the turbos. But theirs a gasket that leads from the block to the water pump. Usually that's what leaks.

Yep that's what I think is leaking. Without anything removed I can't see the source and that is the last potential source left in that area.

Any clue what one might charge or that? I hate removing the downpipes and refuse to do it ever again

Removing downpipes on RWD are cake. Once theirs out the way. It should be fairly easy to do. Even better if you'd remove the subframe out of the way
