WHITE SMOKE, ENGINE NOT WORK
White smoke means you're vaporizing water. It could be a culmination of
1. You've got coolant leaking through your headgasket
2. You've managed to get water in your exhaust through condensation or
When you say it doesn't start what to you mean? It just churns and
churns or it doesn't crank.
If it's not cranking at all you may have hydrolocked the engine or
simple have a dead battery. Parking down slope can causes water to run
into the engine bay. Usually your rubber liners will channel water away
from critical components but you do have your major electrical and ECU
located in the top left portion of your engine bay. This sits right next
tot he windshield and having heavy rains with your car parked down
slope will channel alot of water into this area.
Was your passenger footwell damp? The ECU has a firewall gromet that
runs to the passenger footwell. Water may drain through this point if it
manages to make it's way into the cavity of the ecu bay.
all in all, let the car dry out, give it a go again. Keep your senses at
peak, listen for odd sounds, try to get a whiff of that white smoke,
check for coolant odor and be prepared to stop if something isn't right.
Don't risk a major problem just because you don't want to give up
trying to identify a smaller one. It just gets more expensive.
Hope this help.
