You may have a loose connecting rod bearing or a hydraulic lifter that makes noise until the oil pressure builds up. Has the engine had an oil change w/new filter lately? Try 'high mileage' oil. Have a service shop check the actual oil pressure by installing a mechanical gauge temporarily. You might have a worn oil pump that is a relatively cheap fix. Hope this helps!

Recentley when I start my 2004 chevy silverado truck, it knocks and blows smoke for a few moments, then it runs fine. I have had the vehicle for 6 months.

It sounds like you have a seal problem and that is when you stop over night and the oil up top runs down past the valve seals and when you start it has adrop of oil going onto the piston,s and it burns that oil and also makes the compression a lot higher than it should be ,,causing the knocking and as soon as the oil burns up the noise stops.
