Alloytec Coolant Leak - Rear of block

[Grantedd]

I've got a minor coolant leak at the back of the block on my VZ with an Alloytec V6 Engine.
The thermo Seems to be dry, Any ideas why the coolant comes out the back of the head in this spot ??
(fluid running down over the transmission housing)

Mate have a read through this tread, seems to be similar to your problem, O-rings at front of block, coolant runs down valley to appear to be leaking at rear
