My dad has reported that the X5 3.0i has been using 1 qt. per 2000 miles now and it hasn't been that bad in a while. Recent maintenance has been valve cover gaskets and oil separator with hoses all within the last 15 months and 12k miles.

The valve cover isn't leaking. Would the oil separator and hoses need replacing again? What else could be leaking causing this oil loss?

2 years ago, oil consumption was 1 qt. per 8000 miles.
