If it's the valve seals it will also smoke when you come off throttle as as engine vacuum sucks oil past the seals. If there isn't any smoke, then either it's not the seals, or not enough of a problem to worry about it. When my turbo seals were going, there was visible oil in the rear housing, but thinking about it, it smoked continuously not just on start up. Also, it might just be nothing... the engine is horizontal so maybe oil is running off the sides of the cylinders and pooling at the bottom... and just gets burned off when you start it up. Probably best not to worry about it if it's not using a lot of oil and you don't have to top up all the time.
