WHITE SMOKE

2004 Ford Expedition

Smells problem
2004 Ford Expedition 6 cyl Two Wheel Drive Automatic 67000 miles

i have an xlt that had recently been parked for about a year my truck now has a knocking noise coming from the muffler that gets worse when the truck is heated there is also white smoke coming from the muffler that has a strong smell to it as if something were burning its really shaky while parked and even while driving at some points
it does not accelerate as it should when I press the gas it hesitates to go.
when I turn it on first thing in the morning it hesitates also as if it were going to turn off (sometimes it does) then after a while it accelerates and kicks in as if I was stepping on the gas while parked

White exhaust usually indicates a blown head gasket. Has the coolant level gone down? Have you checked the motor oil to see if there is coolant mixing with the motor oil? Has the check engine light come on?
