Default SHM - Change tolerance to deal with gaps in CAD geom

I have a geometry which has some gap in the CAD, but I am not able to edit this. Is there any way to change tolerance in snappyHexMesh in order to make such gaps invisible to the mesh generator?

The problem is that I have fluid inside this geometry, and I should not. The figure shows the geometry. In the top, it was well recognized, but the bottom part of the engine it was meshed inside it..

Best regards,

I would have thought it would be better to repair the STL using something like the MeshLab:
Then use surfaceConvert function to clean your stl and see that its good for use.
