I have a oil leak in the reversing gear of my 1980 H-27 with the Renault RC8. I had the yard inspect it and they stated that the rear seal was leaking. It's not a lot of leakage just an annoyance. Every once and awhile I add a little oil to it and it seems to run fine. My question-to anyone else who has had this problem, what did you do to fix it? Has anyone used an automotive transmission sealer to fix the problem?
