Was wondering if there should be a vacuum effect going on if I was the pull this line out?
There is air blowing out of the hose that's coming out of the valve cover but there's no air sucking in at the throttle? does this mean I have leak somewhere? the car seem to idle just fine now that I reseal the valve cover gasket.  (pic taken from GetToyota) |

Positive Crankcase Ventilation hose indeed. It's meant to give the various vapours (unburnt fuel, moisture, combustion byproducts) which accumulate in the crankcase someplace to go. In the 5SFE's case, it routes them back into the combustion chambers via the intake manifold.
The vacuum line I like to use for Seafoam is the one attached to the throttle body directly above the PCV hose. This post has been edited by Galcobar: Nov 11, 2011 - 6:18 AM |
