SOURCE: vacuum leak
mine is doing the same, it's your pcv receptor on the manifold. that hard plastic cover is actually part of the intake itself, if it "came off" it would cut your intake in half. that seem seals the two halfs together. you gotta pull the whole intake off and replace it... or jimmy rig it.

Code P1491 is not the PVC Valve.It is the Vacuum Cut Valve Bypass Valve.
Which is located above and away from the egr canister under the driver side rear bumper it is round and have about 3 hoses connected to it. if it is from a check engine light that says look at vacume cut valve check the egr canisters purge valve some times they stick and throw the wrong code
