Definition of Exhaust Emissions

Your car’s exhaust fumes directly result from the combustion process taking place inside the engine. A spark ignites gas and air, and the resulting fumes are expelled through the car’s exhaust system. A catalytic converter reduces harmful emissions, and a muffler dampens noise from the exhaust.

What do Exhaust Emissions appear as?

In normal driving conditions, you won’t be able to tell if your car’s exhaust is coming from the back. Water vapor can occasionally be seen in the atmosphere, as was mentioned in the introduction. It’s crucial to acknowledge that this is not the same as the thick white smoke that led you to us.

Why does White Smoke emit from your Exhaust?

You’ll understand the significance if you’ve ever seen people stranded on an island sending bonfire smoke signals to passing planes and ships. Likewise, white, black, or blue exhaust smoke is an indication that something is wrong with your car. Your car has sent out a distress signal.

If you see white smoke coming from your exhaust, coolant or water may have made its way into your engine. When burned, it produces a thick, white plume of smoke, which is expelled through the block’s exhaust.¬†

How does Water or Coolant enter Combustion Chamber?

The presence of thick, white smoke coming from the exhaust usually signifies one of three things: either a blown head gasket, head crack, or an engine block crack. The fluid can travel through cracks and defective gaskets. The problems begin when it travels.

The most important thing to remember is to stop driving the car. Further contamination or overheating could result from a gasket failure or crack in your engine, which would spell the end of your engine.

You have two options if you want more evidence of a coolant leak in your block. First, the coolant level should be checked. For example, head gasket leaks or cracks can be confirmed if you notice a low coolant level and no other coolant leaks. Additionally, you can purchase an engine block leak detection kit that uses chemistry to detect coolant contamination.

The reality of a blown head gasket, cracked cylinder head, or broken engine block is that it’s time for you to accept that you’re going to need a lot of money and time to fix it. Only by dismantling half of the engine can these issues be confirmed.

It’s entirely up to you where you go from here. We don’t recommend doing this in your garage if you don’t have the right tools because it’s one of the most difficult car repairs. Depending on the car’s value, a repair may or may not be worth it, so consult your mechanic. Whether you want to fix or replace the engine you’re up to you.

Use a proper service manual, and plan, and have the right tools on hand instead if you’re confident in completing the project. When removing everything, don’t rush, and don’t forget to label everything.
