Here is the lowdown. I have an oil leakage at the advance housing. I have installed mikes new style seals, new gasket and new o-ring. Polished the end of the cam before install of the new seal. Polished both sealing surfaces, housing and head area for perfect mating of the gasket and o-ring. Im using new screws with lock washers, torqued to factory spec. It is still leaking. Not a lot, but enough that after I ride to work (30 miles) I have oil blown all over the right side carb/intake and side cover.
It appears that the oil is not leaking from inside the housing, which means the seal is sealing, which in my mind means that there is a breach of some kind in the gasket/o-ring fitment. I have had this housing off five times now and everything appears perfect. No old gasket material or gunk causing the gasket to not seal properly. The o-ring groove is spotless.
Can I and should I just put a thin coat of gasket sealer like yamabond of three bond on the gasket and o-ring?
Any other ideas? Is there anything I could be missing?
