Evap error caused by PCV valve?
Would a leaky PCV valve cause an evap problem? I have noticed that my PCV valve is whistling and making some strange noises, and probably sucking air in. Would this cause a problem with my EVAP system? I think low vacume would.

I doubt it. Our 2000 F250 SD with a 5.4L here at work has buzzed/whistled for years and never thrown a code. If it was sucking too much air, you would get the dreaded P0171 and P0174 lean codes. I would go ahead and replace the PCV valve and check the hose elbows.

that's fine if its not, i assume i still have a problem with my evap, its a 1451, evap circuit malfunction... my edge evo reads out the text for the code as well. I also know my pcv valve is bad and will be replacing it shortly...

Sounds like a bad evap solenoid over the gas tank.
Did this just occur, or has it been going on since the engine swap?

Check the wiring adjacent to the vent solenoid for damage. The solenoid itself should have a coil resistance around 50 ohms.
There is ZERO probability that the PCV valve is responsible for anything related to this fault code.

Thanks thats what i was wanting to know, sho89,
LX ya the 1451 is only a few months old, so it deff not related to the swap.
Speaking of the swap, my new updated edge is in the mail with my stock 5.4l tunes, after i get it i will be working with the company to get it dialed in for custom ones... WOOOT...
