Should I Care About the Color of My Exhaust Smoke?

Should I Care About the Color of My Exhaust Smoke?

Much like your doctor can determine your body’s health based on your output, our ASE-certified technicians can understand the health of your car based on the color of your exhaust smoke.

So what does the color of your exhaust smoke mean? Our professionals answer four exhaust system questions regularly heard at our car shop in Oklahoma City.

Should my exhaust smoke be white?

If your exhaust smoke is thick and white, you may have a problem. You could be in trouble if your engine is burning coolant because of a blown head gasket, damaged cylinder head or cracked engine block.

Thick white exhaust smoke indicates a coolant leak, which could cause overheating and put your engine at serious risk of damage. If this is the case, call our Oklahoma City auto repair shop for an inspection immediately.

However, if your white exhaust smoke is thin, like water vapor, it could be nothing to worry about. Often, condensation will build up inside of your car’s exhaust system and the heat heading through the pipes will create steam.

What causes black exhaust smoke?

While black exhaust smoke is typically easy to diagnose and fix, it can be an expensive issue. If your exhaust smoke is black, it means the engine is burning too much fuel.

This could be caused by several factors, including:

· A clogged air filter

· Clogged fuel injectors

· Damaged fuel-pressure regulator

· Clogged fuel return line

If your vehicle is burning too much gas, it’s wasting fuel and costing you money. Schedule a visit with Christian Brothers Automotive Warwick for a solution today.

What does blue exhaust smoke mean?

One possible reason your car has blue smoke coming from the exhaust is that your engine is burning oil. If the valve guide seals or piston rings are worn out, oil will leak into the combustion chamber, where it will burn with the fuel.

If you see blue smoke coming from the exhaust system, check your oil and continue to monitor your car’s consumption. If the damage is severe, the problem could be complex and expensive to repair. However, a minimal leak could be handled by managing the oil and topping it off regularly.

If your car is turbocharged, the only other possibility is that the blower needs to be rebuilt or replaced. Either way, blue exhaust smoke requires immediate attention. If your car is releasing blue smoke, call for an appointment today.

Why is my exhaust smoke gray?

Similar to white smoke, gray smoke can be difficult to diagnose directly. There are several possible reasons your car is sending gray smoke out of the exhaust system.

These reasons include:

· A faulty transmission vacuum modulator

· Excessive oil consumption

· A bad turbocharger

· An issue with the automatic transmission fluid

· A stuck PCV valve

While these issues could be minor and inexpensive to fix, it’s important to call our shop in Oklahoma City for help if your car is releasing gray exhaust smoke.
