Thanks!
The drop in level may increase to a pint a week like mine did or more. It will seem to be proportional to the amount of time the motor spends running when hot. Short trips affect it less because the system is pressurized less of the time. At this point when restarting after the motor sits hot, you may get a sweet scent out the exhaust that you recognize is coolant. It'* different than the fuel scent.
When mine was very bad on leaking there was a peppery effect to the scent out the exhaust pipe. This was within minutes of my motor starting to foul the plugs and not run well.
My leak was not through the EGR piping area. It looked like the thin rubbery seal next to one of the openings in the gasket that water goes up into the throttle body through had been leaking.
