CA18DET Oil leak - HEELP!

[JDMgravy.]

Hi guys, hoping you can help me out!

I had the cam covers off and checked over the half moon seals, there are no splits in them and theyre in really good nic, so I put some sealant on them and the cam cover seals and put them back on the head.

Fired the car up to check for leaks around the cover+half moon seals, they where fine so I then turned it off after 2 mins.

I looked under the car and there was some oil that had ran down the passenger side of gearbox bell housing!!!

Got under and tried to see where it had come from, looks to me like its coming from the back of the head:

So I had a dig around the back of the head and took some pictures to see if I could locate where its leaking from:

You can see here where the block tranny and head join, this is the turbo side bulkhead end corner:

Is it only water hoses that run around the back of the head/above the gearbox, this threaded coreplug on the head was the only thing I could see that would leak oil? And it doesnt seem to be coming from there either:

The only thing in my head now, is perhaps a blown headgasket? The car runs really well though so im totally stumped and need some help!!!

Valve cover gaskets?
I had mine go on me, leaked oil everywhere.
