Re: smokes blue and white but not burning no oil or
If u have a 302 or 5.0L it probably is early warning signs of burning oil. Check pcv valve and change oil and use a quart of lucas engine restore. It may also be valve stem seals if only smokes when u start it up.

if the smoke is white you have a water vapor problem and it will probably be your egr water cooler and oil cooler. if the smoke is blue, you may have a blown head-gasket or it could be the oil cooler also. take it to a ford dealer and let them put it on their computor, it will cost you a little but it will confirm what you may already know. hope this help's.

This is symptoms of a blown head gasket. White smoke is antifreeze burning in the combustion phase. Oil is also seeping through and being eliminated in the same manner. Check your tailpipe for oil. Also - check your oil. If it is brown/milky instead of black - you have a head gasket failure or cracked block/cylinder. Check the coolant quality too. Floating oil or a brown murk - means the same.

HAVE YOU NOTICED COOLANT LOSS,RECENTLY?KEEP THE COOLANT LEVELS FULL,CHECK TO SEE FOR ANY LOSS AT ALL! OIL SMOKE IS MORE BLUE THAN WHITE,BUT FUEL CAN HAVE A LIGHT BLUE SMOKE.Antifreez more whitesh with a similar smell of antifreeze.
If its smoking that bad you should be able to tell if its oil or antifreeze by the smell, stand behind the car as its running, if its white and you smell a sweet smell its antifreeze if its blue and smells like a oil refinery its oil.
