What causes white smoke to come from the tail pipe with strong fumes while in idle?


A heavy presence of white smoke from the tail pipe is usually caused by a bad headgasket. If this gasket is bad, the vehicle may run rough as well as overheat.

Why is a very strong gas smell coming from my tailpipe?


White smoke is water vapor and in this cold climate it is normal. Strong gas smell is not normal although you may smell some while engine is warming up. Bad cat converter can produce smells, but usually more like rotten eggs. If engine is running rough and seems rich, check coolant temp sensor. Bad converter can cause stalling too. Otherwise, idle speed is controlled by idle air contol motor which can get dirty and stick. Any codes set?

Engine concern


Smoke (blue or black) or steam (white)? White smoke is really steam that is caused by water leaking onto hot surface. Could be leaking from hose running to heater coil under dash, or something else. Check radiator water level to make sure water level is ok. Blue smoke is oil burning. This could be dangerous, caused by similar scenario of oil leaking on a hot surface (from a gasket leak, etc), or exhaust fumes. Black smoke means something is actually burning and could indicate fire. Black or blue some could fill vehicle cabin with toxic fumes, even if you don't smell anything bad.

I have a Hyundai Trajet 2002 Gasoline. I have a problem with keeping the engine alive.


The engine is running very rich that is why the exhaust is emitting black smoke. The engine needs a tune up so the air fuel mixture is correct.

I have a 2000 volvo S70 i smell fumes in side car when driving went to get exhaust checked no problem there what can the problem be?


What type of fumes are they exhaust or oil burning.
Exhaust ..Idle engine and put glove on hand put hand over the tail pipe and if engine stops in 20 seconds then the exhaust is good if it keeps running then its the exhaust is your problem..
2 if ex ok then its due to the breather pipe on the engine and it should go back into the inlet manifold to be reburnt but if its not fitted or rubber hose split or broken then thats what you can smell.
So check out under the bonnet and see if you can smell or see any smokey fumes or sucking noise.
Can you see smoke when you start engine.
Let me know ASAP Ron

I would check the exhaust pipe a little closewr. White smoke can also mean a blown head gasket. Check the tail pipe to see if moisture is present. Also check coolant level. A blown head gasket can also cause related problems.

White smoke exhaust


White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event. If its less then there leak coolant leak in the car engine which is causing this problem....
