Had a few moments this afternoon to pull the heater box out to put a new core into it. It wasnt leaking, but im bloody surprised it wasnt making my feet wet:

Has leaked and corroded so badly that the corrosion (cupric chloride and efflorescence) has actually sealed it up again. When i put the garden hose on it after coming out of the heater box it was leakier than an incontinent geriatric.
Thankfully i had already started lining up an NB unit which will drop in and make future core changes much easier.
I also added some lightness by gutting the aircon box:

The heat exchanger is easily the heaviest part there, and just gutting it will make for a good weight saving.
