SMOKING WHEN STARTING

1988 Mazda RX7

Engine Mechanical problem

I just had a new rebuilt engine installed. When first started, a good amount of white smoke blew out the back. This was after the car sat for a couple of months. The smoke lessened with each start, and now only a small puff of smoke exits when started cold. Nothing when started warm or while driving. Is this normal, and will it stop as the engine get broken in. Thank you.

Could be if it wears in-if not replace the valve seals
