Antifreeze leak, not Water pump

[KentuckyC]

Leak in this air intake area. Back of RH side, below the reservoir. Reservoir is good, no spray on block from water pump or any joint on block. Running down from area above, toward clamp Any ideas?

I've been losing about a 1/2 pint every 3k no leaks that I can find, not ending up in the oil and it doesn't seem to be burning any. I just top it off and send it

Most leaks from coolant come from Pressure forcing it out. You need to have a test run on the coolant system. Doing this as a DIY is somewhat risking. You would get the engine HOT and then look for a "stream of mist" in the area you already suspect. It must be HOT to create the pressure that you need or you can use a Pressure Gauge. Perhaps Auto Zone or other parts shop can lend you one. Good Luck.

I am confused by the photo. You indicate RH side. Does this mean the driver’s side or passenger side?

Also, the “air intake area” or air box is on the driver’s side. The “reservoir” is on the passenger side.

Have you removed the air box and are we looking at the transmission vent tube in the photo?

RH is passenger side. This is the tube coming from air box around behind top of engine, then turned down to turbo. This point shown, is just past point where it turns down, easily identified by the hose clamp.
I pulled the hose clamp and mounting bolt , reached inside to find tube is wet internally with antifreeze. Assumption is, one of the vacuum lines off top of motor is sucking on antifreeze from crack in head.
