Is the car runnig little rough on cold start up in themorning for few seconds?? Because I have done quite a few headgaskets on QG18 Sentra aka 1.8 liter nissan sentra. here is the test. Fill up your overflow bottle to the full mark and check the coolant level in about 5 days.(drive it normally as if nothing is going on) If the level is down, your head gasket is gone. How about the check engine light , is it on?? post results.

This is usually an indication of a bad head gasket.I gasket. The white smoke is the coolant leaking out of the engine and winding up in the oil passages, due to a bad head gasket. To confirm this,
1. check oil. Is level increased, or milky appearance?
2. Is coolant level dropping, but u don't see any signs of leaks?
The above indicates a bad head gasket, causing the white smoke u describe. Let me know how u make out.

You must have a leak under your hood. Find the leak and fix it.

White smoke is caused by water and or antifreeze entering the cylinder...If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.
Good luck..i hope this helps.... please rate me a fixya
