This may be due to improper bolt clamping of the starter motor.
1. Remove the starter motor.
2. Using a M10 x 1.5-6H tap, clean the threads of both upper and lower starter motor bolt holes in the engine block to remove any excess material. Clean the holes with shop air.
3. Reinstall the starter motor.
