Fact is; it's a substantial amount. So much so that there is research on the acids formed from combustion byproducts dissolved in said water.

But lets say someone came up with a hypothetical high heat hydraulic like seal that never leaked anything to under the piston.
IF
I dissolve Boric Oxide in water and add it to the engine BELOW said seal.
THEN
How is the seal pertinent to the lubrication and surface protection abilities of BA on the other side of said seal..?
As for a completely clean, same as before, magnet on a sump plug:
Yes they are much cleaner once the engine is run in, but there's always a small amount of very fine particles on the sump plug magnets of an engine with std engine oil.
I looks like a grey/er layer with a sheen in sunlight.
I rebuilt my 1st engine at the age of 10 or 11, so no; I DO NOT consider a sump plug magnet that looks like a school experiment with iron filings normal wear. 
(Makes me wonder what exactly your opinion of me is..? And, as respect is mutual; why you should expect mine of you to be any better..?) |
* 'Water' cannot exist within the combustion chamber during oxidation of the charge.
* 'Water vapor' does exist, created by the hydrogen in the long chain hydrocarbon molecule combining with oxygen from the atmosphere.
* The only way it can make it to the crankcase, to compromise the engine oil, is by 'blowby' past the compression rings and oil-control ring.
* Whenever the crankcase temperature is at, or below the 'dewpoint' of the water vapor-charged gases, the water vapor will condense into liquid water, which on wintry days you'll see 'draining' out of the tailpipe, and, or, forming visible 'clouds.'
* Other by-products of combustion can possess a pH low enough to be acidic, which can eat away at certain metallic surface treatments. This is one reason for the oil change interval recommendation.
* Properly functioning piston rings exhibit a magnitude of blowby that is statistically meaningless.
