Day three: cracked nipple coming off of manifold... (Pics/Questions)
Alright, I found that leak coming from the back of the engine, and it wasn't that the line was blown, or torn, but rather the nipple itself had cracked below where the clamp was located.
Day 1: https://www.rx7club.com/3rd-generation-specific-1993-2002-16/intercooler-line-blew-way-work-now-there-big-coolant-leak-ideas-438344/
Day 2: https://www.rx7club.com/3rd-generation-specific-1993-2002-16/found-coolant-leak-worst-spot-ever-cant-even-get-438812/
Talk about a bitch. Here is what she looked like. (Notice the pool under the nipple)
Access was difficult but we managed...
The leak was about here...
So now we dropped the hose, lowered the clamp, and this fixed the leak. We will be returning to this nipple later in the year when we rebuild the engine and look into our options about sealing it up a bit.
Now, we are trying to put the manifold back on, and we have a few busted vacuum lines and plastic nipples. We know where most of them go and how to replace them, but I do have a few questions.
*Searched* Are there any diagrams that show you which connectors go where on the underside of the manifold? I have the shop manual and it does not help too much, also I couldn't find anything at robrobinette.com.
Firstly, what are these? (The green part) The previous owners seemed to like "glue" instead of solid plastic nipple connections...
Can I just pick up replacement parts for these are the local store? Thank you all in advance for your help!

PM DaleClark, IIRC he has viton check valves for sale (I think it was the 4 units for $20 or something like that) that supposedly are much more durable than the stockers. Definitely replace them before the rest start failing on you.

Also, these were plugged.
Also, two of the hoses coming off of the manifold were plugged intentionally by the previous owner.
The car was boosting 10--6--10 with them plugged.
At this point, I'm going to leave them plugged. They seem to connect down into the rats nest for a solinoid, what happens if that solinoid is not functioning?
When I get replacement check valves, I will unplug them, and properly connect them.
Also, I should be able to access these without the manifold being put back on, correct?

just fyi:
one way check valves are..well, one way check valves. go to auto bone or pick n pull and grab one off of any car. that'll save money over the dealership. there's nothing special about them.
