question about oil injectors (2nd Gen) T
 

ok after a week of looking for vaccum leaks i sprayed some starting fluid where one of the oil injectors is and the idle changed. so i assumed thats where the vaccum leak was at. took the UIM off and went to replace the lines and used zip ties to secure the hoses but i still have the leak when i blow thru the oil injector. so after some water and soap bubble test i noticed that it wasn't the hoses leaking the air is comming from the sides of the top plate on the oil injector. now is this normal or my oil injectors need to be replaced? attached is a pic of where the leak is at. thanks in advance.

here is a drawing of the top of the oil injector maybee this gives you a better idea.
the air is comming out by areas painted in yellow.

You're gonna want to replace those injectors. Just do all 4, since they are too important to not have working properly.
