It's NOT piston rings, 9 Bar of compression is acceptable, but to loose water and oil, in my experience is 1 of 2 things,
Failed head gasket/warped head,
Water cooled oil cooler,
The first being leaks through to the cylinder, but on ALL 4? I doubt it.
The second meaning the oil and coolant would mix and it's possibly burning off the mix through another gasket, the inlet manifold gasket for example.
