Smoke out the tailpipe
 

I changed myoil about a month and just took a trip to Ft. Lauderdale from Cocoa. Fl. WhenI arrived with in the city limits my oil gauge start moving to the low oil area. The next morning I check my oil and the dipstick read empty so I put more oil in an started the blazer and a large amount of white smoke came out. The same thing happen when I return home. What can be the problem ?

Sounds like a possible blown head gasket...

Well...the gauge is oil pressure, not oil level, and white smoke is coolant, not oil.

Either way, if youve got coolant in the exhaust, its probably headgaskets. But of course, with any coolant leak, you need to get a pressure test done to find the leak.

Also, just in case it is the headgasket, you need to check the oil dipstick and cap to look for evidence of coolant/oil mixing. Also check your coolant level. How fast do you lose it? The oil pressure very well could be linked to a badly blown head gasket.
