Sometimes my attitude indicator shows a slight bank when aircraft is level. Gyro has between 50 and 100 hrs sense over hauled. Vaccum pump less than 50. My heading gyro drifts maybe 5 to 10 degrees in a 4.5 hr flight... well within limits. So I don't think it's a vaccum issue.
I know by turn cordinator shows a turn in the pic. Aircraft was level. There was some thermal turbulence today when I took that. So aircraft was rocking a bit.
