Another thing you may want to check if the spark plugs are firing. I had a simular problem once before with the white smoke, and when I pulled the plugs out one wasn't firing. It was wet with n gas. Bad plug was causing the problem. Change the plug, and problem was gone.

The first thing I check when I'm told a car is blowing white smoke is if its low or lossing coolant. White smoke is almost always Steam! check compression if your lucky it'll just be a head gasked, (low compression on to ajoining cylinders ussually indicated aburned through gasket)Low compression on just one cylinder could indicate a gasket blown to out side (rare) cracked head ussually 'tween valve (most common ara for heads to crack)or a cracked cylinder. This last failure will, however usually be accomanied by milky oil (water in oil)or bubbles (lots of 'em,)in radiator as cumbustion gasses are force into the water jacket). Odds are if the enginge hasn't overheated to warp the head or froze to crack the block it a head gasket or cracker head.
