Can You Have White Exhaust Smoke With a Blown Intake Manifold Gasket?by Robert Tomashek
Smoke coming from the exhaust indicates a problem with your car, but the color of the smoke can point you towards the correct diagnosis. Different smoke colors can be caused by the following issues: grey or black smoke can be a rich condition, white smoke can be burning coolant, blue smoke can be burning oil.
Intake manifold leaks.
A leaking intake manifold gasket can cause white smoke from the exhaust, if the engine has coolant flowing through the intake manifold. A dry intake manifold will not cause this symptom.
