Vacuum lines V70-XC70

posted by  someone claiming to be zedzed on  Sat May 28 09:34 CST 2005 [RELATED]

Cleaned flame trap/PCV valve and now hear a strong vacuum leak near passengers side intake manifold. The elbow with the hard plastic vac. line that runs along the maniflod to the flame trap is OK. I can see it clearly attached to the manifold right by the PS pump body. This mystery hose has a fairly large ( 7mm inside diameter ) soft rubber elbow going to a soft rubber sheathed line. It is under the intake manifold, sits naturally by the elbow shown at "Bay 13" photo. Can't see where it goes. Any experience with this one? This is in the area where the oil collector box (?) is. Don't want to pull the manifold for a loose vac. line.
Been to "Bay 13", good site, but does not address this situation.
Also, on non-turbo V70s, does the crankcase have a turbo return oil line plug?
Possible source of oil leaks? I am trying to find an alternative to what appears to be a Rear Main Seal leak. Thats' the original reason for all this.
Thanks...
