Black puff followed by blue puff


Stage 1s, the chip is out, and it's about 40 outside, first thing in the morning.

OK start the truck and a slight bit of white haze comes out the pipe continually, give it a little pop of the throttle and a block of black smoke puffs out followed by an equal puff of blue smoke. I can do this three or four times before it starts to clear up. Drive 100 yards and I can't get it to puff the same.

Why is there blue smoke? My oil level is at max, so I'm definitely not loosing any. I havent done a compression test yet.
