The PCV valve on my truck is connected to a hose that branches into a Y. One side of the Y connects to the back side of the Air Intake. The other side of the Y looks as if it goes to something behnd the engine but I cannot find or locate where it connects to. If anyone can tell me or has an emmisions diagram it would be greatly appreciated.

Wish, I could answer better. My 02 4.2L goes throttle body to pass. side then angles back to just behind DIS and into valve cover.
