Case oil leak

Hi guy's, I have developed a oil leak in the case coming out of the threads from one of the bolts that hold the two halves together, the particular bolt is the one directly behind the water pump, has anyone else seen this issue?

I was thinking of going in and pulling the bolt and putting some tread locker on it and seeing if that stops the weeping.

Regards,
Kent

"one of the bolts that hold the two halves together"?? Are you referring to the center seam of the engine? Bolt heads are on the LH side of the bike?
You could degrease, dry & try some Loc-tite blue. Snug to about 70-80 INCH Pounds on all those small bolts.


"behind the water pump"?? Do you mean holding Clutch Cover on?

Bolt at 3:00, try some Loc-tite blue, on the threads & under the head.

Bolt at 6:00, Refer to JT Crow's post.

Sorry about the confusion, the bolt that is leaking is one of the bolts that holds the two case halves together, the threads where the leak is coming from are located looking from the front of the bike back at the engine on the left side to the right of the water pump, yes I think that pulling the left side stator cover off I should be able to access the bolt and pull it out and lock tight the bolt and tighten to spec.

Hummmmmm!

There is no reason yet to pull the stator cover off. Use brake cleaner & compressed air to back flush and dry the threads in place. Then use Penetrating Grade or Wick-n-Loc thread sealant.

My engine has had a slight 'weep' from the upper center seam, under & behind the starter motor, for about 30 years.
I spray it down with Engine Degreaser & hot water, once or twice a year.
