(I initially posted this is the performance section before realizing it should go in here. Sorry for the cross-post if I can't figure out how to delete the other one)
I need help identifying where a vacuum line begins and ends on my '04 Alero 3.4L. I discovered, quite accidentally, that the line was broken. I could not find where the other end of it is supposed to terminate.
I looked all through AllData but there is no information on it other than two part numbers (also not sure why there are two part numbers for the same diagram point). Those part #s are 12581196 (Harness, Emission System) and 24508188 (Tube, Crankcase Ventilation).
Still not being able to answer the question of what it is and where it's supposed to be connected on the other end, they had a mechanic come out and look at it. He couldn't figure it out either.
Here is a photo of the top of the engine where one end connects. Can someone take a look at theirs and tell me, with a photo if at all possible, where the other end of the tube should be going?
