    Loud Hissing coming from under the hood

    I just got my car back from the dealer 2 days ago from them replacing the engine. I have an 09 wrx that had the dreaded spunner bearing issue..

    This morning when i started my car it sounded like a loud air hiss coming from under the hood. Then as i started to drive it almost sounded like a pressure release from time to time as if i had a BOV, which i dont. I did notice it stopped makin the hissing noise once i got to the first red light, but faintly heard the hissing as i was driving.. Just curious if anyone has a clue what this might be, but im at work now and havent had a chance to check under the hood, just looking for ideas because im a tad paranoid now that the engine is new and freshly installed.. Let me know thanks!

    +1^..Do you have an aftermarket intake on the car or anything? Where there any drive ability problems? Did the CEL come on? Either way as mentioned I would take it right back...However I find it kind of odd that the tech who hopefully drove the vehicle after the engine swap didn't notice it...
