Substantial coolant leak somewhere under upper air intake manifold

[SpenserAK]

PHH was pesky at best, but approached properly as described above, no big deal. My bypass was gross on the bottom so I trimmed the end & fixed the small leak, but still need to replace it with the new hose I bought.

Haven’t got all the details yet.

Picked up rig from dealership: 4 hrs of labor to drain coolant, flush system, pull intake manifold, replace both hoses in that area (throttle body hose and PHH) and clamps all OEM, replace a small heater hose at the radiator and clamps all OEM, install intake with new OEM gaskets, fill coolant and burp, test. Inspected entire coolant system. I’m ok with that.
