How does a head gasket fail within 10kMiles?
Poor parts quality? Overtemping? Over-rev'ing?
..and more importantly, are there any ways that an owner can prevent it?

Thank you

I'd think that overheating or extreme oil pressure would do it.

The interesting thing for me working in the oil and gas industry is that the 550 dry sump reservoir is acting like a water separation tank, this process is often used in crude oil/water separation where the mixture of oil and water that comes out of the oil well is then allowed to separate by natural gravity (oil floats on water) in a settling tank for a few days.

The 550 dry sump reservoir is having the same effect, maybe due to lack of use, cooling effects, the high height of the reservoir (aids the gravitational settling) or entrainment (the flow is trapped in the reservoir).

Of course, the oil you buy from the store should never have more than a very low % of water in it, so the water is coming from the 550 coolant system via the head gasket leak.

One addition to this thread, as well as head gasket, water in oil can also be caused by leaking cylinder liner, other symptoms are water spurting out the spark plug hole during a compression test.
