Exhaust throws smoke

Hi guys, when I start my car in the morning I have a question that strikes my mind, it throws blackish smoke from the exhaust. There is an exaggeration in the car. ? I will make any problems, and if the car starts to throw more and more oil is missing from the top cover, then we will do it, he said. Could this be the reason?

top cover you call my rocker cover & nbsp; the smoke event has nothing to do with the rocker cover or the cylinder head, check the air filter if it is clogged.

thanks for the info .. & nbsp;

No engine burns oil & nbsp;
