The Monte and the El Camino have different places where this happens. The El Camino is about 1/2 to 3/4" from the left, The Monty is 2 mm. It might be the plastic thing that controls the plastic tubes (I had to replace on the Monte) that is bad. It was hissing though, and was a vac leak on top of the problems with the heater doors.
