Had the same issue several years ago with a CFM56 on a B737NG we had to ground the aircraft to remove the engine for a shop investigation due to high oil pressure,the warranty covered the engine removal/replacement and shop work but did not cover loss of revenue, after all an operator could claim any amount to cover that with no really clarification or proof of income lost.
