The spout at the front of the engine that connects to your top radiator hose has 2 seals. These seals leak into the area below where the intake manifold bolts up and pools in the valley, When you drive it runs to the back of the motor and down from there.
Commonly misdiagnosed as thermostat when its simply 2 rubber seals that need replacing.
Pressure test doesnt show anything because the leak pools in that valley where you cant see it, then runs out when you drive.
I'll mention this to the mechanic when the car is dropped off on Thursday. Although if it was under pressure for 30 minutes do you think it would have pooled enough to start dripping. The mechanic pulled me under the car as it was raised, and there was a clear line of stain running down the block, just couldn't be 100% sure where it was coming from. I don't doubt there is a leak, I just haven't seen any other signs of it being the thermostat - except for where the stain is coming from and the location of the drops.
Might be an idea to run the car to operating temp tomorrow, but not drive it? And see if theres a drip once she gets warm? If there is, I can assume its the thermostat, and if not, good chance its the leak you mentioned, and I havent had a leak because I havent actually moved the car, therefore the pool hasn't shifted? If thats a decent experiment, I'll give it a try tomorrow before I take it in the following day?
