I know that the subject of oil leaks has been covered countless times and apologise for raising it again. However, I can't find a previous answer for this particular set of circumstances.
When I leave the bike parked, it leaks oil from the RH side of the engine (nothing unusual about that, I know).
Removing the outer timing cover shows oil pooling and weeping out through the join; it actually drips from the rear RH stud of the sump, but this is only because it tracked to that low point.
The oil is entering that cover through the small breather hole low down in the gearbox inner cover - presumably this is the timed crankcase breather?
On some occasions this leak is barely more than a drip, on others however, it makes a fairly massive puddle. I can only surmise that the difference is due to whether the breather is timed open or not.
So, I have a two-part request.
1. Can anyone suggest a method of curing the leak?
2. If not, is there a method of determining whether the breather is open or closed without waiting for the puddle to form?
Any insights will be gratefully received.
