Until you change the thin viscosity 30 weight break in oil thats in there to 20w 50 oil and you know it's not more than halfway up the safe range on the dipstick it may smoke like you're describing.
It also depends on if new Mahle pistons and cylinders from a sealed box were installed, used ones, or JE pistons, and if they are used ones or JE what the piston to cylinder wall clearance is and are the ring lands in good condition and not worn.

Not enough information to make a good guess.. but first thing you have to do is get the thin viscosity 30 weight break in oil out and 20w 50 in and don't over fill it.
For now don't fill it above halfway on the dipstick safe range while the motor is idling at operating temperature. Only time I would fill the oil tank to the top of the safe range dipstick marks is before starting out on a long trip or before a track day if you do that.

It would be best to use non synthetic oil until the motor has at least 600 variable rpm and engine load street miles are on it so the rings seat in completely. That depends on how you drive it too. Baby it too much and rings take longer to seat.
After that 20w 50 full synthetic oil is better than non synthetic.
