If the components were not installed correctly this is possible to cause this issue here.White smoke can generally indicate a head gasket leak as well as the coolant in the oil pan.I suspect this may be what is occuring here more then anything else.I would have a block test done to see if a head gasket leak is present causing this here.This is a quick test most shops can do taking less then an hour and you can purchase a block tester from a local parts store as well to do this testing.
