Can you clarify this setup a little. Are you injecting air into the coolant
side of the system and looking for air bubbles on the raw water
side, or the opposite? Is the engine
running in this configuration?
I also have a leak that I have not been able to trace down yet. I pressurized my coolant
system to 12PSI and there was nearly no drop in 2 hours, and only a drop to 9PSI after 2 days. I'm guessing in my case it's either the radiator cap, or manifesting only when the engine is warm/vibrating.
