It is on a P72 head. It's a brass bolt that has an allen key socket. On the back of the engine by the fuel rail and distributor. Right on that corner, i guess upper-left if you're looking from the front of the car.

 

don't have a pic?

I would assume it's just a tapped oil hole thats been plugged up because honda was thinking ahead when casting the head. though of course, that's just a guess.

 

probably the plug to the vtec oil supply

 

THe one in the upper right of this pic?

 

Yeah that's the one....what is that brass plug?

 

Can't find it in my Helms....ttt

 

Looks to be tapped into a coolant galley. Maybe a drain plug? Tis all i got.

HTH,

It's for oil. That's the plug that gets take out and replaced with an AN fitting going to a steal braided hose that runs down to the block in an LS/VTEC setup.

 

can you use that bolt to tap for an oil feed to a turbocharger

 

You serious?

 

im just wondering dude,,shut up.

 

Whups thought you said that you could use it. I asked in FI and they said yeah.
