water jacket leak test result
After cleaning up all of the oil drips and laying down a layer of bentonite, floor dry, to spot any water. And filing the rad and wiping up any water spills, I pressurized the rad to 20psi.
Fixed a couple of hose clamp leaks, but that was it. No seepage or leaks I could find.
The strange thing is that the pressure would drop rapidly to about 15psi after about 10 minutes, then slowly stabilize at 12psi. Can't explain it.
I repeated this test several times, but could find no leaks of any kind. I will recheck it tomorrow night to see if drops below 12psi. If it is stable, back into the car it goes.
