GMC SIERRA BURNING OIL PROBLEM

2004 GMC Sierra • 100,000 miles

I have recently noticed that I have been losing antifreeze but no visible dips or puddles on garage floor also noticed truck gives off a puff of whats looks like burning oil when I first start it then it goes away. Just bought the truck warranty is gone and not to happy. But truck runs fine. What could this be?

Smoke could be valve seals.

Cooling system has a leak. Get a pressure test to find the leak.
