An unusual xs400 has a leak...

[DANIEL RAMOS ALTEMIR]

Hi I'm Dani, from Spain, I own a sanglas 400y (spanish made with a japanese engine) that has a leak on a crankcase bolt because aparently the PO tightened it too much.

Here you have pictures (bolt 10) to identify it and I would like to know a good way to solve the leak by myself. I was thinking in a gasket or maybe thread sealer, what do you think?

Gracias!

Haven't split the case myself so I can't speculate on why it's leaking.
Crack in the casing?

Could try putting a gasket or crush washer around the bolt head.
