Small hair crack in cast aluminium sump

[AndyStobbs]

How deep is the sump? Must be considerable stiffness in the sides.

Oh it must be about 170mm or there abouts. Im probably worrying over nothing, hopefully get it back together tonight anyways.

I doubt if your'll find any distortion on the gasket surface, I'd be more worried about the drain plug sealing, personally.

it looked like a good tight fit this morning before i left for work.
Some have suggested using a nylon washer as a seal

 

[zzr1200]

A soft copper washer or a dowty seal would be my choice if the drain plug has the correct mating surface, possibly an "O"ring depending on the drain plugs design.

PTFE the catch all for when the surface isn't flat haha

Well, its all back together, after 100km no signs of leakages!
