my car has been having some problems that seem to be due to a vac. leak...

i have a hear the leak coming from the back of the intake manifold..

i looked back there and it lookes like there is some kind of vac. port that has several different vac. hoses coming out of it.

has anyone had this plastic port thing break and cause a leak?

 

am i the only one who has seen this thing or what?

 

is it plastic? or the metal T?

 

im pretty sure its plastic.. its looks pretty worn/old

 

well then replace it like 3 bucks

 

whats the name of it? i've never seen this thing before
