Evap manifold and ported check valves direction of flow
Just when you think you have the lion by the tail, a skunk scurries up behind you and pees on your leg.
When I replaced the emission hoses, I forgot to put the check valves back inline.
Theres one at the manifold pressure coming from the intake manifold on the passenger side and another one at the ported pressure coming from the throttle body next to the MAP sensor.
My stupid question is (I know, there are no stupid question, just stupid people)
: which direction do they go? flow into the intake manifold or out; flow into the throttle body, or out?

Flow goes into the intake manifold. Under the hood should have a sticker of the vacuum diagram. www.autozone.com has their repair section with tons of vacuum diagrams if you need it.

Thanks Crazy. I try to do my research before asking, but even after two hours scouring the net, autozone.com, and even AllData 09, all I found were the same diagrams, but they confused me on the flow. I had concluded the funnel type image of the check valve on the TB meant flow into the funnel end, but the manifold side had me stumped.
Thanks again.
Thanks again.
