Question about Cars & Trucks

I have gas venting issue that will not allow me to put gas in the tank on a 2005 Alavanche.

I have changed out the chacoal box, vent val sensor and also the other one on the engine.

    Sounds like a venting issue...check the filler neck(where the pump nozzle goes in) for obstruction.. If you disconnect the vent hose from the vent hose extension..the extension might be blocked...

Do i need to change my val cover gasket and do u think that will solve myproblem of my oil leaking so bad i am not sure i think that is my problem the val covergasket needs to be changedchanged

Wipe the cover and the area below it clean with some rags. Then run the car awhile and check if the clean area has new oil that leaked out. Usually oil leaking from the top of the engine is the valve cover.
