New mufflers smoke because of the paint burning in or if not painted the raw metal has a slight film of oil from the manufacturing process and to prevent rust of the raw materials. Mufflers typically operate at 300-450 degrees.

Why does the smoke coming from your muffler has a smell?

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.


Can a hole in the muffler cause a car to smoke?

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.

What causes oil to come out of your lawn mowers muffler?

The problem I had was oil and gas flowed out the muffler on my snapper 11 hp lawn tractor. To fix it I had to drain the oil and get a new plug. The issue that caused it was I needed a shut off valve in the gas line to stop the gas frome running back into the engine and eventually getting into the oil causing it to gush out the muffler with a lot of smoke. It is an easy fix and it now runs as smooth as new. I hope this helps you
