HZJ-T80 Headgasket leak ? (2 Viewers)

[AdamFire]

I’ve got a 1990 hzj80 that has 420km on it. It has had a GTurbo on it the past 10k no issues and set at a moderate 13psi with EGTs at a typical 300c.

Ive noticed a recent leak at the back of the engine as shown in photos. It is not coming from the valve cover as far as I can ascertain.

no bubbles in the radiator or fluid mixing.

Is there some other seal that I could be missing or am I looking at replacing the headgasket.

I noticed mine also has a slight leak from that same area. Hasn't impacted any performance and its about ~35,000 KM

I know it’s really hard to see the back of the head, but could it be oil coming from the half moon plug thing at the back of the head, just below the valve cover? Then seeping down and travelling along the top edge of the block?
