After the truck is parked for a while when I start it up white smoke comes from underneath the hood. It only last for a few second then its ok. The truck isnt leaking oil or fluids nor is it overheating. Smells like burned oil. I just had all of the spark plugs replaced and a coil replaced

No, it started after I got the spark plugs changed and a coil changed as well.

Before that there was no smoke coming from underneath the hood when I start the car

Open the hood and have a helper start the car so you can see aprox where the smoke is coming from. There has to be some kind of leak.

Ok. I was thinking valve stem seals, worn rings, PCV valves. I will look and let you know. I just hope it isnt serious

It appear to be coming from the drivers side. It also sound like the spark plug are not firing together on the same side. All fluid levels are good.

Start by checking to make sure the plugs are all tight. Also, is there a misfire?
