Oil Hole?

[ZacTsi]

Hey guys, so my car burnt a valve and I had the head machined with all new parts. Now I finally got it all put back together and there is a mysterious hole on the side of my head opposite of the timing, and I saw a little oil in it so I knew it was probably tapped all the way threw. This hole is located by the thermostat housing actually right above it. It looks like a bracket probably goes there but I dont know why they would have it tapped all the way threw the head. I dont remember removing anything that was there so maybe the machine shop forgot to give me a plug bolt or something that fits in there. Any help or someone who knows what this hole is would be great help. Thanks!

Holy crap ok thanks, good thing I haven't ran it yet. That's weird I don't remember taking that off!

Thats an oil galley, the machine shop may have removed it to clean the head.

you're not the only one who was wondering about it. I didn't notice it at first though, just got a new head and rebuild, oil came right out the side haha.

Haha yeah thats what happened when I first started it up. Well thanks for the help guys

Oh wait is that the standard oil feed for my 2g car or is mine fed from the oil filter housing?

 

[BogusSVO]

IIRC 1g is fed from the head, 2g are fed from the OFH

 

[ZacTsi]

Okay thats what I thought, Thanks

Ya, that's the feed for the turbo for the 1G setup. Banjo bolt goes in there.

Wow, I've never noticed that before. I'm soon going to a 6 bolt (with 7 bolt head) and 16g so would this setup be more beneficial than the OFH setup?

Yes but if you see more than 50psi worth of oil pressure up top or on cold starts you should get a restrictor.
