Help with vacuum lines
A while back, the engine belt on my camaro (L99 engine) had to be replaced because somehow, from what I understand, a vacuum hose got in the way and damaged the belt and also de hose was cut. My mechanic said it was fine to just take the hose from the vacuum out and just put a plug in the hole where it use to connect. i did that and have never noticed anything strange. but now i really wonder what was the function of that hose? I tried looking up the part, finding if it connected to something else to other hole in the engine but i cant find any information. i attached a picture so you see what I am talking about. the house used to connect to the hole im pointing at. does anyone know what it is and if I should fix this? or trust my mechanic? In the picture i took out the plug I normally have on it so dust doesnt get inside.
