about the best pic i have right now is this one

if the link doesn't work, click on it again, put a space before the web addy and hit enter. You can trace the brass check valve back to a metal one, then a hose makes a 90° angle to the metal branch you were talking about

just found another pic

that shows where it connects to the branch better.
An aftermarket BOV shouldn't be hard to install if you get a kit. I've heard that some BOVs will fit the stock hose, but i'm not sure if you wanted it dangling off a hose. If you wanted to do the DIY mod, which alot of people swear against, then you just need a Check Valve like the one in my pic, and a hose to fit it. Then get a threaded nipple to fit the hose and check valve together and you're done. Mine still let a little vacuum leak, so I just tightened the spring a little. good luck
