My car keeps blowing smoke out the exhaust? Is it because the engine is cold, or it might be cold outside?

not within minutes...could take 20 min before all moisture is vaporised and heated up...

Hi Eric no this is not a lecture but something you do need to know a modern engine uses a fact of physics in that water or coolant kept under pressure can be at a much higher temperature before it boils. so the boiling point of water is 100 degrees C. however in most modern cars the have a radiator pressure cap which makes the coolant get a lot hotter.for every pound of pressure the boiling point is raised by 1.5 degrees C so a 15 pound radiator cap raises the temperature by 22,5 degrees C. so your car should and could get to 120 degrees C which would save you fuel and would be the normal working temperature. Now you have starting issues which does point to a pressure leak. It could be a loose hose or a worn out radiator cap. as the spring becomes weak over time. then there is the other possibility that the head gasket has blown yes although you see no evidence in the exhaust it can still be blowing. small amounts of coolant at a time and the fact it doesn't get up to a working temperature does suggest a pressure leak somewhere in the system. so has it used more fuel recently as that would also be down to not getting to a working temperature.

SMELL the exhasust. Yes i said smell it. If it smells sweet you are burning anti-freeze which means you either have a blown head gasket or cracked head. Also check for green residue in the snow under the tailpipe. Another tell-tale sign are bubbles in the radiator when the car is running.

smoke at start up is a sign of valve trouble, what you saw could be condensation, if you smell anti freeze in this smoke you have a blown head gasket, good luck

Have the cylinder head gasket checked. If this has blown then this could explain the white smoke.

It's just because it's below freezing and the car is putting out very hot air. Same reason you see your breath when it's cold.

If it was thick white smoke you might either be burning oil or bought bad gas. Check your oil levels every couple of days and get gas at a different station then normal. After you get new gas if it still dose it take it to a shop. Just don't forget to check your oil level often!

Sounds like it's due to the cold weather.

Sounds like rings or head gasket. Either way, it needs a shop.

The cold does bring air into the exhaust line...
