ok. yung last tune-up was a long time ago. that can be also a culprit.
another reason is that probably, you have been going through floods the past few days. may water sa loob ng exhaust system.

afaik, white smoke is water, black smoke is oil.

most probably it needs tune up nga, or check mo yung end ng exhaust pipe kung maitim or may langis,baka kumakain na kasi ng langis pero wag naman sana

Yes, white smoke in your exhaust is an indication of water and if it does not go away after a few minutes could mean engine trouble. If it's just moisture due to flooded roads, then the steam in the exhaust should stop. If the white smoke persists, it could mean water mixing with oil/fuel in your pistons. You may need an overhaul. Check the water in the radiator for oil or if you always need to top up the engine oil. Oil in the radiator means there might be a leak in the cylinder head. Engine oil that gets used up quickly can mean loose compression. I suggest your bring your car to a mechanic or shop so they can look at it.
