During a routine 100hrly inspection/oil change, a substantial quantity of solid debris [crushed aluminum in appearance] was found in the oil tank. The engine was removed and sent to the Rotax agent, where it was stripped and inspected. No sign of contaminant or damage was found. Only other way for debris to enter the oil tank, is through the oil filler cap.'
