If the cylinder failed you'll have a crankcase thats filled with coolant as the two will intermix at the point where the cylinder fails.

Being a 99, the cylinders are inherently compromised. See if you find any blue paint marks on the crankcase from the factory. It almost looks like overspray.
The oil and coolant seem fine

What would blue paint indicate?
