White Smoke From Tail Pipe/Exhaust

I have a 2004 Suzuki Forenza 04, the oil & engine light were flashing, I checked and topped up the engine oil. Still light flashes. I then did and oil change and replaced plugs.

Now there is white smoke coming from the tail pipe/exhaust. What have I done wrong or what is the problem.

Thank you

    Mine is a 2005 Forenza.  First I notice cool air coming from the heater.  The car did not overheat, it actually ran cooler than normal.  So I'm thinking thermostat.  I checked the fluid level and it was almost empty, so I filled it with antifreeze.  All seemed good so I thought problem solved.  Today, white smoke billows out the exhaust and the check engine light flashed for 15 seconds and went out but the smoke just got worse, engulfing the entire car.  I pulled it over and it is being towed to dealer.  I'll let you know what I find out.

    My 98 Ford Escort Zx2 had white smoke coming from the exhaust, The oil was over full. I have drained the oil and refilled it to the proper amount. This fixed took care of the smoke but there was a slight misfire which started after driving with the excess oil. I replaced the spark plugs and plug wires after which the white smoke had started again. could their just be excess again from the oil drained out of the spark plug holes?

It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling. Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings

Hi Bibio,

As a rule:

  • Black Smoke = Unburnt Fuel, incomplete combustion, bad mix
  • Blue Smoke = Burning Oil
  • White Smoke = Water Vapor, Water getting where it shouldn't be.
White smoke is common in cold weather when you first start your vehicle. It's from condensation. But it should stop as the engine warms up. If it doesn't, the moisture is from another source.

Th oil light and low coolant were likely the first symptoms of a blown head gasket which got worse. It wasn't something you did and there was nothing you could have done to prevent it at that point either.

Your engine running cooler for a time may have been a false reading. Some sensors need to be in contact with the coolant to read the temperature correctly. If the coolant is too low, the gauge reads cool when it's really too hot.

Symptoms:
  • Coolant levels low. As the coolant is burned off, you'll notice white smoke and the levels are lower
  • Oil in the coolant. If oil is present in the radiator, it's coming from the engine. Another indicator of a failed head gasket. Only a confirmation though, lack of oil does not rule out the possibility.
  • Water in the oil. If you recently changed the oil. It should be clear and clean. Pull the oil dipstick. Is the oil still clear and clean? Or is it milky and frothy, like it was whipped? If so coolant is getting into the oil. Again, an indicator, not a confirmation of a blown head gasket. Lack of blue smoke says that oil contamination is unlikely.
  • Lack of power. Just before the smoke screen, was there a sudden loss of power?
The quickest, easiest and (most importantly) cheapest confirmation of this is to run a compression test on each cylinder.

The test should show high and fairly close compression (100psi or more) on all cylinders. If any of them are significantly lower, something is allowing the gasses to escape. Since valve problems are usually accompanied by horrendous noises and piston ring failures would produce blue smoke, that leaves the head gasket.

If you feel comfortable doing it yourself, testers are available at any auto parts store for under $30.00. If you don't, any shop can do it in under half an hour.

All this is to pin point the problem. Then you know what you are dealing with. The solution is to replace the head gasket. Although labor intensive, the parts at least will be relatively inexpensive.

Comment me back with your findings.
Mike

I have a 2005 suzuki forenza.. I loose coolant like its nothing no signs of leak.. Low rough idle..I replaced the plugs and wires and 02 sensor Engine light flashes at idle and stops flashing but remains...


Check your oil----is it very high? Put a piece of cardboard under your car overnight, see if you have any leaks externally. If not, then you have an internal leak, which indicates a blown head gasket.

Smoking was coming out of my hood and my car was shaking. My check engine light was blinking, this never happened before. suzuki forenza 04


If the light flashes on and off, the vehicle has a severe problem that will cause additional damage. You should not be driving the vehicle.

2004 Suzuki Forenza-- flashing check engine light, hesitation


Go to library and get an automechanic's Diagnostic and Repair book or manual.
Simply check out the possibility whether the negative response that you are getting from your car matches the mechanical data found in the repair book and manual.

AND NEVER forget to consult an attorney for FREE advice concerning laws governing the legal responsibilities of auto mechanics (there are attorneys who do NOT charge a fee for the first 30 minutes of advice) Check yellow pages. GOOD LUCK!

Runs rough when cold


On start (Especially in Cold temperatures)it is harder for the oil pump to bring oil to the top of the engine,making noise more prevalent .Keep fluids level and oil clean and you shouldn't have to worry.
