I don't know how it'll sound this time, I haven't put it back together yet. Last time I had it done at the dealer, after I picked it up, the car smoked all the way to my house. i didn't see the white smoke until I got home bc its after 9PM and its dark, and my gf told me she saw it skmoke all the way from the dealership (she's driving behind me). I swear I could hear something strange in the engine. I had to take it to the dealer the next day because they were closed. By the time I got there the smoke's gone and the strange noise didn't sound that strange anymore, go figure h:
