Vacuum leak on '81 ZX non-turbo

[Takeiuchi]

I've got a vacuum leak in my 280ZX, and I can't seem to find a Vacuum diagram online or in my Haynes manual. I'd rather not go out and buy a Chilton's JUST for the diagram.
If you could help me out, it'd be greatly appreciated.

the vac lines on thes car are pretty easy to ge to an inspect or replace, I suspect your issue might not be a vac leak, what is the car doing?

The car seems to run fine, but there's a pretty loud hissing noise somewhere in the engine.
It's also leaking antifreeze, but that's a different, easy fix.

Sorry for the double post, but now I have ANOTHER problem.
The hood's stuck. The hood release won't do anything, and prying open the hood with hands/screwdriver's isn't doing anything.

thats nto good

when you pull the handle, does it feel normal? one person prying up while the other pulls handle not working? any idea why it's stuck? I've ehard of people getting the saftey latch jammed into the catch but you shouldn't be able to get it closed all the way, I can't remember if you can get the hinge e bolts woth the hood closed ont eh s130
