10-PCM P0410HC Air System-B fault

[mdevese]

Hi c4c5 specialist,
I have taken the left check valve off and blown through it both ways, the rubber tube side (into the manifold) air passes, the threaded side (manifold side that should be closed when blown) air did not pass by mouth. While I had it apart I disconnected the 5/8 tube by the washer tank, started the engine blocked the pipe and had air pulsing from the tube that would go onto the check valve I had just removed. Does this mean that the check valve behid the engine that goes to the right bank is faulty? Ant thoughts on this mate. Thanks

Michael.

If the air is still hitting the windshield then there is still holes in the lines. You may have to run a hose from the back of the intake to the cansiter and from the cansiter to the line going into the firewall. The third line comes off the cansiter and almost straight up and over to the inner fender well, most likely this is ok but you should find it and check it out.
