Did ant metal come out with the oil? I would believe it is fine, but I would at least take a cover off and look if I could.

A lot of the oil we carry in sumps, etc. is for endurance, sort of like having a 20gal gas tank vs a 1gal tank. need to stop and refill less often. As long as the gears had oil on them and weren't overworked, they should be fine.

Interesting story... A Dash8-300 once landed at an outlying airport and the crew reported problems selecting reverse thrust. The propeller and engine use the same oil supply. The mechanic checked the oil by the sight gauge and thought it was full (as had mechanics for the previous few days). He tried pouring in a quart anyway, to see the line move. It didn't... Eventually 14 qts went into a 12 qt reservoir. So this 2000hp engine was running for several days for multiple flights per day with only the oil that was on the gears. No damage was found when the engine was examined. I don't recommend filling less that manufacturers recommendation, but as long as the oil doesn't get cooked and the parts in contact have a film of oil, lubrication will take place.
