A compression test won't always reveal a blown head gasket. Have you drained your oil to see if there is coolant in it, or done a leakdown test?

White smoke is burning coolant. You need to do a leak down test to verify how coolant is entering the combustion chamber and get back to us with your results. Are you familiar with a leak down test? If not will post a link when I find it.

FYI regardless of how the coolant is entering the cylinder the engine is going to have to come out to be repaired, actually scratch that you can repair a head gasket without removing engine completely. But be prepared for some work ahead


this is the first one I found on leak down tests which is actually a really informative video http://www.youtube.com/watch?v=GvG22YMOzUI

Just recommend this. Take the radiator cap off and crank the motor. See if coolant is forced out. If it is you are getting compression into the coolant jackets.

White smoke is a mixture of vaporized droplets of water and fuel!
