Have recently noticed clean oil residue from a leak after several flights on top of the reservoir for Rotax 912 ULS. Took cowling off and cleaned up area and removed cap and top of reservoir and checked all including hoses and rubber O Ring on reservoir. All appears normal. Crimped band holding top to bottom of reservoir and reinstalled with proper torque. Still have slight leak. Could the pressure from oil system be causing oil to come out around O Ring and pool on top of reservoir? If so, what is the proper fix? Has any one else had this problem? Thanks for any suggestions and help
