Isl 400 smoking on startup

[Alfa Gold isl 400]

I would say it’s gray color smoke. It’s about 55 degrees out. The grid heater gets hot when the wait to start light is on then turns off when light goes off. The heater does not come back on after the engine starts. According to Cummins it won’t come on after the engine starts at this temperature. I looked inside the turbo. No oil on the inlet and outlet of the turbo. I did not look in the exhaust side of the turbo. I did part of the gasket missing on the leaving side ignition the turbo. Between the cac and the turbo. Would this cause smoke on startup?
