My sled was on it's side for awhile on the hill while getting unstuck and when I fired it up there must have being some oil in the exhaust or turbo as it smoked a bit, probably 10-20 seconds. Then it cleared up and never did it again all day. There was also a little bit of oil on the suction side of the compressor upon inspection when I got home. Any ideas on this. Did a little oil get pressured through the seal in the turbo? You would think if a seal was bad it would smoke all the time. I ran it hard for the rest of the day and never missed a beat. Thanks.
