Is that caused my rings are done? When i start my car and let it sit to warm up and give the motor a little juice it has a nice cloud of white smoke with a blue tint... i was thinking blown headgasket but if that was the case then wouldnt my oil be milky and my coolent res. be empty, and my car be over heating like crazy? Another thing i noticed my car backfires alot more any idea what tha could be? When i engine break i get back fires that no joke sound like gun shots... im runnin a straight pipe if that makes a diffrence.....
