i rencently had my b16 rebuilt,and after the rebuild i started it up and i had a cel for my ect sensor.so i did not drive the car now i got the sensor replaced and now no cel,but now it burns oil really bad .all of my friends say lots of blue smoke when i accelerate.the car feels as if its running fine.but it smokes really bad.could oil be getting into my cylinders from my headgasket

 

did you have your rings replaced in the rebuild? who did this rebuild? it is possible that the cylinder walls needed some honing or slight boring. maybe they just replaced the rings and you need to break it in still.
