Weak Crank Case Bolts?

[pekingduck]

Update: Did it. Test drove today. No leaks. Thanks for everyone’s help and 2c.

Note: there was hardly any sealer on the right cover from the factory. The left side was removed before. (Probably when the tip-over happened). There was a lot of the original sealer still on and whatever was used to redo it. However the bottom bulb. Where the slow leak was didn’t have much sealer at all.

The most important things IMO are getting those surfaces as CLEAN and degreased as possible and making sure you have a consistent strip of sealer. Had to use a combo of Rasor blade, finger nail, break clean and tweezers to get all the old junk off.

You're quite right about the cleanliness of the surface. I save old toothbrushes for this. The sealant not only keeps oil in, but water out, as pressure washers can blast at 1000-2500 psi, more than enough to penetrate your skin.
