SOURCE: White smoke, at the first start of the engine and

Does it use any oil, or lose any coolant? If not, do you make a lot of short trips, then shut it off by chance? If your not using oil, or coolant, then I'd say take it on a long drive at highway speeds to drive out the moisture laying in your exhaust system. Recently had a muffler go on wife's car that does a lot of short trips, and old muffler was almost full of water from condensation and obviously poor exhaust design, that allowed it to build up like that. Took it next night on trip about an hour away. Every time I took off, or passed a car, white smoke rolled out the back. On way home, it stopped and cleared up.

SOURCE: blowing light smoke and burnning engine oil

Blue smoke is usually oil burnig related. White smoke is due to coolant mixing with the oil. (Head gasket leak) You should have the coolant system pressurized by a garage to see if your system holds pressure. This test will tell a lot. Coolant in the oil is a big problem.

SOURCE: My isuzu 4JA1 engine tends to exhaust white smoke

White smoke means that you have a coolant leak. Two possible causes for that - either the head gasket is punctured and must be replaced or the head itself is damaged and must be welded by an expert. 
Either way the engine must be dismantled to make a full diagnose and repair.

2005 Nissan Path:replaced batt, alt, plugs, coils due to rough run & smoke. 1st smoke was blue after new parts it's more gray or white. New plugs smell like fuel. Exhaust is rich in fuel smell. Ideas?


Blue/grey smoke is typically engine oil burning.

Grey/black smoke is typically excess fuel (or insufficient air).

White smoke is invariably water that has turned to steam. (water is a natural product of combustion as well as the stuff the head gasket keeps out of the cylinder).
Sometimes an engine can emit a fine mist of unburned fuel that seems like white smoke.

Clearly your engine is burning some engine oil. Perhaps the valve stem oil seals are failing. When an engine noticably burns oil it must be realised this isn't good for the oxygen sensor and catalytic converter and it is inevitable the life of these things will be shortened.

It is doubtful the replacements you have so far carried out will have changed anything and it is likely to be coincidence the colour of the smoke has changed.

What is needed is a diagnostic check to inspect the live data from the sensors when it will probably be found one or both oxygen sensors will need replacing and perhaps other things have grown tired too - at an extended mileage an injector could start dribbling or the spray patterns be so poor the engine won't be able to burn it all and then it will be expelled into the exhaust.

How do i fix smoke coming off my car?


Don't drive the car. With white smoke, coming out of the exhaust, you must have blown your head gasket. It will also evaporate the cooling fluid, making the engine run without cooling.
Look for a certified repair shop, to get this repaired.

Excessive white smoke from tail pipe


White smoke:

White smoke is caused by raw, un-burnt fuel passing into the exhaust stream. Common causes include:
·Incorrect fuel injection timing
·Defective fuel injectors
·Low cylinder compression

Low cylinder compression may be caused by leaking valves, sticking piston rings, ring wear, cylinder wear, or cylinder glaze. When white smoke occurs at cold start and then disappears as the engine warms up, the most common causes are fouling deposits around piston rings and/or cylinder glazing.
Continuous evidence of white smoke indicates a mechanical defect, or incorrect fuel timing.

White Smoke when i put gas in car


The most common cause of blue (or worse still) being expelled through the exhaust system is extreme wear in the engine, or, if you're extremely fortunate a significant OVERFILL of the engine oil level. One other possible, though unlikely cause, is a fault in the engine's scavenging system.
Has this problem occurred suddenly without warning? Had the car been serviced immediately before this event, or the engine oil topped up?

I got white smoke, changed head and head gasket, intake gasket looked bad. My question is: can a bad intake gasket cause the white smoke?


Not on a Gas engine, but diesel engine yes.

Diesel engine white smoke means leaking head, intake, or your turbo is not working.

Gas engine leaking intake would only cause rough idle, no power, etc,,,,

2004 1.6 vvt renault scenic smoking and juddering and ``check emissions`` message on dash and orange light ?


White smoke is a symptom of coolant entering the combustion chamber which usually indicates a blown head gasket. Blue smoke is a symptom of oil burning. Black smoke is a symptom of an overly rich fuel/air mixture. Have the ECU scanned with an OBD2 scan tool. This will retrieve the cade that has been set by the ECU. That code will tell you what part is being effected and where to start looking. If you see white smoke STOP driving this car immediately as serious engine damage will occur if you continue to run the engine. It must be repaired ASAP.

Heap of white smoke on startup but not always


White smoke usually occurs when there is not enough heat to burn the fuel. The unburned fuel particles go out the tailpipe and typically produce a rich fuel smell. It's not unusual to see white smoke in the exhaust during cold weather until the engine warms up.

Faulty glow plugs or control module can cause white smoke on engine start up.

Low engine cranking speed may also produce white smoke.

If white smoke is still visible after the engine has warmed up, the engine may have one or more bad injectors, retarded injection timing or a worn injection pump.

Low compression or air in the fuel system can also be a source of white smoke.

Cold start up problems and engine runs bad and smokes white smoke


I believe you have a glow plug problem. How long does the (wait to start) light stay on before you try to start it.
