Its called a rubber vacuum line elbow
On a 4 cylinder it's screwed into the back of the intake manifold, just about in the center with a white, round plastic 2 wire connector plugged on to it. On a V6 it's on the top, center of the upper intake plenum (same connector) and pointing towards the firewall.

The connector into the intake manifold of a GM 305 and 350 has been known to be quite fragile. If the connector has broken you have little choice but to replace the manifold.
It's located in the air intake (plastic tube) which runs from the air filter to the air intake manifold. It is plugged into the plastic air intake tube and has a two wire connector plugged into it. It is located near the center/front of the engine bay.
If you look at your air intake tube you should see a connector going to it, that connector is going to your iat sensor. Ther is no connector on air intake tube but severl connector on intake manifold?
The intake manifold is underneath the plastic silver cover held down by four nuts. Take it off and you'll find the intake manifold - also plastic. Even more unusual, the starter is underneath the intake manifold!
That would most likely be the intake manifold. I expect you can get a replacement manifold at any car part replacement shop. If not got to a Chevrolet dealer.
for the 2.3L 4 cyl. motor, it sits on top of the plastic intake manifold which faces the radiator.
A bad intake manifold or manifold gasket can cause water to leak into the oil. Some newer cars have plastic manifolds and they will crack from age.
The e36 M50 has a timing chain. The e30 has a belt. Black plastic intake manifold = Chain Metal intake manifold = Belt
attached to the lower intake manifold on the belt side usually little plastic bushings are broken on those
usually your intake manifold is ok...the manifold gaskets are prone to failure..they are plastic with rubber impregnated seals...if the manifold is actually pitted, you can repair with JB WELD then sand smooth.... ase master certified tech
It has a piece between the lower intake manifold and the upper " plastic " intake manifold . If you look at the engine from the passenger side , approximately 1 + 1/2 inches from the engine oil fill cap / tube you can see the valve where you test the fuel pressure just below the " plastic " upper intake manifold
