Oil filter cover oil seepage on 4PT
 

Anyone had troubles with oil seeping out of the oil filter cover? I've helicoiled the bolts holding the cover on deep inside the engine, and got a new filter cover and brand new gasket. All original Yammy. Leak is still there.:helpsmilie:

I see. That little rubber seal probably fell out the first time I changed the oil filter, and has been missing ever since. Those seals are few and far between. Nobody seems to know about it. The bike shop didnt. I've since put in a seal from a tap washer kit, which was the right size. The leak has reduced down to almost nothing, but I will be checking if I can get a proper yammy one. Thanks for the advice:thumbup1:
