Sounds like you might have a set of glazed rings and bore, what sort of new motor are we talking, is it a complete new pistons, rings, bearing , the whole she bang or is it the old new rings bearings and hope

look if its blowing smoke now how long is it since the engine was fitted and how many Ks has it got on it now, most engine reconditioners will tell you that when you first start her up to give her a couple of good revs to stop this happening and first drive to take it out to 4,500 grand in first and second on about 3/4 throttle and then drive it normally not over reving or labouring the car for about 500 Ks and then change the oil and drive normally
