Leak on 2g cylinder head below tsat housing

[Talyn]

My head seems to be missing an oil or coolant plug that goes below the tstat housing, its a 2g head, I don't recall removing a plug from here and am having trouble finding a bolt that fits right, don't want to risk crossthreading it. Anyone know the size/thread pitch? Or is this where the oil feed for the turbo would be if I didn't have a filter housing feed? Either way I need a plug for this...Finally had the car running again and had to shut it down when I saw the leak.

EDITED OUT INCORRECT PART: See below for actual p/n. Sorry OP, i was off by a quarter inch , wtf is wrong w me sometimes?

There are a total of 3 of these, iirc. i just pulled my head. They are all the same size and i believe this is the OE part. I dont see any other plugs like this anywhere else on the the block or head so its gotta be it. The one in the front facing the front of the car, is what some use to feed the turbo. I suspect one of the 2 on the side are leaking and im not sure what they hold back but i think they all lead to oil passages. Dont quote me.

there are more than 3. 5 maybe total. regardless, thats the plug you need

boost97gst sounds like he is heading in the right direction. There is no 3/8" BSPT plug on the head so the above linked part is not correct.

It's this guy. So what exactly is the thread type/pitch, anyone?

They are listed as 1/8" BSPT, not something you'll find at your local hardware store.
