check your oil.
if there is a little water in the oil its usually a head gasket.
If nothing, check your engine block for cracks. If it has overheated recently it might have cracked the block, causing loss of both, and messing up the cylinders.
Driving through flood water would cause the ignition to fail and stall the engine.
water pump, oil, water, engine coolant....main cause would be engine coolant, just check to see if you have a leak.
i think it is cause of smoking if someone smokes then he/she coughs black that would be cause of smoking
That would require fixing / replaceing the VALVE SEALS in the heads.
Worn valve guides? New answer : Worn valve guides WILL cause some what of a rough idle and engine would smoke at all times. If engine smokes at start up only and then quites then your problem would be the VALVE SEALS.
The engine overheating, or a faulty gasket, or problems with hot spots in the engine.
When you see white or grey smoke coming out the exhaust more than likely you have water in your engine. when it first begins it smokes a little but when the problem gets worse, it will smoke alot. Your head is either cracked or warped, this will cause your engine to get real hot.
Water in engine-head gasket most likely.
No, low coolant would cause the opposite.
Bad water pump, the seal is gone. Get a new water pump.
white smoke does not always mean oil. Where is the smoke coming from. Sometimes small pin holes in the water system can cause a white smoke or steam which appears to be smoke. If the engine is at idle that would be the only time you could see that type of hole until it gets bigger. Check for any loss of water/antifreeze in the vehicle.
water in the fuel can cause an idling motor to sputter and/or die.
