Engine case - sealant?

[Bretty]

Hi all,

I'm going to split my engine case to replace the gearbox.

What is the best readily available sealant to reseal it?

Thank you!

When I did the gearbox on my Jawa 350 I reassembled the crankcases with Hylomar Blue. It worked a treat. If it's good enough for Rolls Royce it's good enough for me.
