Intake manifold ports

[desmo1098s]

My search produced nothing . On the intake manifold there are (3) parallel ports/nipples on the back by the throtle body. On mine the top nipple is capped off, the middle nipple is the pcv hose port.......what is the bottom nipple? Mine has nothing attached. Thanks in advance.

I have the Ty up on stands tuning her up through the next week or two. It also appears that the vaccum line has been cut right after the check valve behind the fpr????......here we go, the fun begins.

I believe you're talking about an unused water connection. Should be a matching port on the front.

Re: Intake manifold ports

You are exactly right. I also found a few dis-connected vaccum lines. Hopefully she will be "back" in a matter of weeks once all my parts get here.
