I've got a 91 DA Integra and was trying to replace the PCV valve and of course it broke. I took off the breather chamber to get to the bottom parts of the PCV but ended up with a big mess of broken hose pieces etc.
The first picture is what I have left in the intake manifold, viewed from the top.
The second picture is from the bottom.
My question is: what pieces do I need to get from the dealer to put this all back together?
Is the plastic piece in the intake manifold part of hose #4 in the last picture?
If so, how do you replace it? It seems like a hard plastic piece so I'm not sure how you get it through the intake manifold if you were to replace it.
Any help is appreciated.

In case someone comes across the same issue I thought I'd say how I resolved my problem.
I have a spare B18b engine from a newer Integra and realized the PCV system is essentially identical on it. The hose that goes through the intake manifold seems to be a re-design and is a softer rubber which easily slid out of the hole in the B18b intake manifold.
I cut out the rubber grommet/piece of hose in the above pictures from my current manifold and put in the hose from the B18b. I also swapped over the other breather chamber hose since mine had broken and used the B18b breather chamber as it was almost new looking.
In the future, were I to work on a B18A1 PCV system again and needed to replace these parts, I'd order hose #4 in the above diagram from say a 95 Integra to get the improved hose grommet thing.
