The VE head has a threaded hole right in front of the oil passage. I think a bolt for the water pipe bracket goes there. It won't be used for that after this
Here you can see the stock passage that gets the oil for the soleniods via the block. It's oozing it's last bit of oil.
You need a 11/32 drill bit for the 1/8 NPT tap. I would recommend a drill press, we didn't have one handy.. so we used the eyeball/hand method
I blew air through the hole to get any loose shavings out.
This is kind of a crappy picture, but you can seee the stock oil passage now that we've cut through. I stuck a pick in there to get any extra metal out.
Now it's time to tap. I used a 1/8 NPT tap with some synthetic grease on it. The metal shavings get stuck to the grease leaving us with a clean "hole".
The 1/8NPT to -6AN fitting goes in nicely. I put some teflon tape on the threads when I did the final tightenning for extra insurance.
It's the same process for the oil hole on the bottom of the head. Except you need to plug this hole. I used the 11/32 drill bit to make the hole bigger. Then I used the 1/8NPT tap to thread it. I bought a 1/8NPT plug to uh.. plug the hole. I needed to make sure it was flush at the very least since it wouldn't have sealed right against the headgasket I used. I also used a bit of teflon tape when I did the final assembly.
The head is ready!
