The smoke from your muffler has a smell because what is coming out of the muffler is the products of the incomplete combustion of your fuel. Some of those products are gases and vapors that have color and some are dark but small particles - that is what you call smoke. But some of what comes out are various chemicals that your nose detects as odors.
There isn't much a person can do to stop the stinky smell of exhaust from the muffler. This smell, sometimes like sulphur or rotten eggs, is a by-product of the fuels burned.
You may have a blown head gasket.
your car is burning oil.
Hi there,blue smoke on a diesel motor is normally fuel,and the smell will be unburn diesel,rough start and heavy smoke that will disapear as the engine getshot.
Just having a hole in the muffler won't cause smoke to form. Any smoke coming from an engine is caused by either environment changes (white smoke while engine is warming up), or an engine burning oil (blue smoke). Sometimes even a bad catalytic converter can cause smoke. The hole in the muffler simply gives the smoke a way out. Trying looking for external oil leaks or checking he oil level occasionally to see if it is burning oil. You may see water vapor is there is a hole in the muffler but it wouldn't last long once the muffler warms up and the moisture is burned off. She shouldn't see actual smoke unless there is a problem with the engine.
If you see a lot of white smoke coming out of the muffler , that is the sign.
Most of the time it is caused by a hole in the heater core, do you smell a sweet smell? The sweet smell would be the antifreeze.
you need a new heater core

If you have white smoke coming out the tail pipe and the smoke has a sweet smell to it, the car has bad problems.
NO!! White smoke indicates the burning of oil. The law says, "ANY smoke coming from the engine during any part of the test is grounds for failure." I've been an Emissions guy in Denver for 23 years. White smoke is oil. Black is gas (too rich). Black smoke can get pricey. White smoke is always pricey!!
Your headgasket is bad, coolant is getting into the combustion chamber, hence the thick white smoke and fluid. had that happen to my dads thunderbird a few years ago
