Depends on why the oil is 1 qt high.
There was a classic call in on the Klick and Klack car talk show involving a high mileage Mercedes diesel. When the caller's son drove the car it used quite a bit of oil, when the caller drove it, the car didn't use any oil, but when the caller's dad drove the car, it made oil.
It was all caused by different driving styles and when the old man gently drove the car, fuel was leaking past the rings and accumulating in the sump, which diluted the oil.(not good) At any rate, if yours was just overfilled, remove enough oil to bring it back to the upper line.
There was an old tech bulletin warning of problems with some M119 V8 (gas) engines caused by overfilling the oil. My M119 never uses any oil, and I keep the level about mid way between the two marks. Don
