Dear Registered User;
The following new Service Instruction has been released by Rotax:
SI-914-021 - OIL LEAKAGES IN THE AREA OF THE CYLINDER BARREL FOR ROTAX ENGINE TYPE 912 AND 914 (SERIES)
This new service document may be downloaded from www.rotax-owner.com

SI-914-021 - http://www.rotax-owner.com/si_tb_info/getdoc.asp?USERID=byteboy&DOCID=SI-914-021&S_TYPE=NW
THE SUPPLEMENTAL INFORMATION SHOWN BELOW IS GENERAL IN NATURE AND IS NOT INTENDED TO REPLACE THE INFORMATION PROVIDED IN THE SERVICE DOCUMENT.
ALL OWNERS, OPERATORS AND MAINTENANCE PERSONNEL SHOULD OBTAIN AND CAREFULLY REVIEW THE FULL TEXT OF THE SERVICE DOCUMENT.
Due to deviation during the assembly operation, some isolated cases of slight oil leakage in the area of the cylinder barrel have been noted on the new style crankcases. For repair purposes, Rotax has created a special gasket which seals this area.
Please note that only engines which display traces of oil leakage in the area depicted on the appendix of the Service Instruction SI-912 019 / SI-914-021 and for which the serial number falls within range listed in section 1.1 of the Service Instruction need to comply.

I don't think this will effect us that has had aRotax 912 for a while. This is for the newer engine serial numbers. The gasket they are talking about is really a double "O" ring that is stuck together. We went over this bulletin in class. You would only have to do this if you are affected by a leak. These are just "O" rings that slide over the cylinder head studs. The ones in our engines are a single "O" rings and the fix is a double "O" ring.
If you have a leak it will be at the base of the cylinders at the crankcase.
