burnin oil and smoke out the valve cover

[kslice88]

i have a non turbo 1g converted to a turbo. its the 2.0 and im runnin a 14b. i was in 2nd and i hit it and i was pushin around 10-11 psi when i heard what sounded like a coupler blowin off (which know i think was detination in one of my cylenders) so i pulled over and when i pushed in the clutch it died. all the couplers were still on and when i started it back up it started smoking outa the breather filter and outa the oil cap hole. i was leaning towards a cracked piston,at first i thought it was the rings but i havnt lost any power which makes me think cracked piston. just wondering what everyone else thought. any feedback would be helpful
