Water in sump

[trxtim]

Have a problem with no.1 t-rex, fill the rad with water and watch it come straight out the sump oil drain plug hole
Is this likely to be a head gasket or cracked barrel or something silly like an o-ring
I have ruled out the water pump and seals as that still holds about a pint after the sump has stopped draining.

I`m afraid it`s an engine strip to ascertain the problem.
