I have a 97 f350 that blows white smoke gets worse as it warms up . No gauges acting funny no over heating. Coolant is low . Don't have any leaks that I'm aware of . Drove it 120 miles as it sits with no problems besides the smoke. Smoke is white and smells sweet . Really need to figure this out soon. Thanks everyone
It's is a 5.8l

 

Sounds like a head gasket

 

Maybe not head gasket leak, but intake manifold gasket leak. A head gasket leak will push combustion gasses into the cooling system, causing it to overflow, and smell like gasoline. The intake manifold gasket is under vacuum most of the time, which would suck coolant through a leaky gasket into the combustion chamber, which when burned will exit the exhaust as steam.
