Short gist: drained and filled coolant system when replacing timing cover gasket and all heater/radiator hoses. Drove it many times and a few hundred miles to self burp and have been filling the overflow bottle to the proper point when needed.
I smelled a slight faint of coolant through the vents a few weeks ago. I thought either a heater core leak or just that some coolant made it's way into the heater box when changing the hoses and re-filling. I did fill up the core before installing the hoses, to lessen any air bubbles. I do believe some spilled over.
Just in case, I just did a coolant system pressure test to 15 PSI. FSE states that if it drops more than 2 PSI in two minutes, then check for leaks. It dropped only 1 full PSI at the 7:30 mark.
Is that 1 PSI drop after all that time to be expected on a leak free system, when working with a rental pressure tester?
Another note: The coolant system pressure will still hold (to a certain degree, of course) after days of the car sitting, with a small amount of pressure release when removing the cap. I would think on a system with even a minor leak, it wouldn't do that after days of sitting.
