mean the paste will mix up with the oil and then moisture contained in that paste will vent out?
to me its kinda risky n tricky, i would like to wash/clean the milky/paste as much as i can using petrol or acetone etc, then let it dry reassemble and pour fresh oil to be used max 1000/1500 km.
reason: the oil-water mixture losses its lubrication capability and can damage the precious metal, so why take risk.
