I doubt it would be a turbo then, as your entire inlet and intercoolers would be covered in oil. Also unless the inlet manifold is extremely poorly designed you wouldn't get oil vapour or pools of oil into the 1st cylinder only.

Well, that's what I thought. It would be very strange to get oil from intake manifold only into the 1st cylinder.

What nobby said. Also, why would it only be on start up if it was the turbo. Sounds like a drip of oil from the valve stem seal. It it's the case then it will fairly rapidly get worse.
