Ok so i started to notice like bad white smoke. In my mind I'm thinking already about the headgasket >.< But i noticed smoke coming from under the hood but from the header. Once i removed the heat shield from the header i see a nice line crack its not huge but still a crack about 3" long between the inner 2 cyl exhaust from. Could this be the the problem of the smoke? My temp is normal, no coolant loss, no leaks on the parking spot. Should i just get someone to weld the crack on the header? Any clues? Well any help will be great!

I have this same crack when I bought the car. You can't weld, header gets too hot. I had it braised so I can do emissions. But this is a temp fix only. It's already opened up again. You will need a new header. Thing is the cat is attached to it so it's really a cat/header therefore expensive. I'm currently searching for a good afforable header and am going to custom high flow cat at the bottom like normal systems. I suggest the same for you. As for smoke? This crack does not cause it. Your problem lies elsewhere.

it only smokes when it revs. Idle no issues there, plugs got changed yesterday as well oil change.
