Are you blowing smoke? Is there blue, white or black smoke coming from your exhaust? This is a sign that something is wrong with your vehicle. A vehicle should not produce any smoke if operating properly. Now you may see steam on a cold morning from the condensation and that’s normal. Hi, I’m Nancy at Kneble’s Auto Service Center. Blue smoke from the exhaust usually signifies that the engine is burning oil. Many reasons can be the cause for this symptom, so have your auto technician determine what the cause is for that blue smoke so you can have it repaired. When your vehicle burns oil, you are at risk of damaging your catalytic converter and oxygen sensors. Also, you must be aware of your oil level as a low oil level can cause your vehicle to lose oil pressure. Now the white smoke from the exhaust, that usually signifies the engine is burning coolant.
This can be a serious problem, so don’t ignore the symptom. Leaking coolant can be because you are leaking coolant from the head gasket or possibly a cracked cylinder head. And finally, black smoke can be normal in older diesel engines. But today’s diesel engines, have systems in place to prevent the black smoke. Black smoke coming out of a tailpipe in a vehicle signifies a problem. This can mean your fuel mixture is too rich. So you should have your vehicle diagnosed by your auto technician as the cause can be many different things, from faulty fuel injectors, a sticking fuel pressure regulator, or a faulty sensor. So don’t blow smoke out of your tailpipe.
