what is the piece on the inside of the lower intake manifold (has 3 vacuum lines coming off of it) on an 87 TII? what does it do? do i need it? can i just put caps on the nipples? used with the BAC valve? all emissions devices (EGR, Air pump, etc) are already removed so.....?

 

anyone? diregard comment about being part of BAC sorry i meant ACV....

 

I don't know, but you may need to wait more than 20 minutes before you reply to your opwn post. More knowlegable people will be on tomorrow.

 

hahahaha your right, im just so anxious to get my car back together, been sitting for a few months now....

 

inside of the lower intake manifold....uh there arn't any vac line on the inside of the LIM, though if you are talking about the vacum lines going to the ACV, cap those suckers OFF!!!

 

there are 4 lines the run from the inside of the LIM to the UIM just behind the throttle body

 

well I just looked I my vaccum spider, in my closet and they all 3 goto the ACV so I'd assume you can cap them off if your not running one

 

coo, thank you BlackRX7

 

No Problem man, just lets bump this up so the real gurus can see this...though I'm sure that thats all it is..

 

The Valve on the inside of your LIM is the Sub Zero Start Assist. 1 line should go to the resvoir near the wiper motor. This can be fully removed, and you can JB weld a quarter or a nickle to the hole on the manifold when you are done.
