Okay... so u know on the b16a head where the upper radiator hose connects in... there's a little nipple on the backside of that big piece... right behind where the hose goes in.

WHERE DOES THAT NIPPLE CONNECT TO? hahaha

I am lost without it. It's one of the last few things... other than axles, alternator, and figuring out what I want to do about power steering. LOL

anyhow, thanks.
