Much like your doctor can determine your health based on your output, our ASE-certified technicians can understand the health of your vehicle based on the color of your exhaust smoke.
So, why is your exhaust smoke colorful? And what does the color of your exhaust smoke mean? Our Texas auto experts answer four exhaust system questions regularly heard at our car shop in Schertz.
What does blue exhaust smoke mean?
Blue exhaust smoke can be quite a surprise. Unfortunately, if your car has blue smoke coming from the exhaust, your engine is burning oil.
There are two possible reasons why engine oil is being burned:
- The valve guide seals or piston rings are worn out
- Oil will leak into the combustion chamber
Blue exhaust smoke requires immediate attention. If your car is releasing blue smoke, call our auto repair shop in Schertz for an appointment today.
Should my exhaust smoke be white?
Actually, your car shouldn’t be releasing smoke at all. However, thin, white exhaust smoke could be nothing to worry about. The heat heading through the exhaust pipes will often create harmless steam.
On the other hand, thick, white exhaust smoke may indicate a problem. White exhaust smoke could be caused by:
- A cold engine
- Leaking head gasket
- Cracked block
- Cracked cylinder head
Thick, white exhaust smoke could cause overheating and put your engine at serious risk of damage. If this is the case, call our automotive shop for an inspection immediately.
What causes black and gray exhaust smoke?
Gray or black exhaust smoke usually means the engine is burning too much fuel. There could be several reasons for this, most commonly related to incomplete fuel combustion.
If your vehicle has a diesel engine, the likely causes include:
- Malfunctioning fuel injector
- The wrong grade of fuel
- An overheating engine
- The ignition timing is off
If your car has a gasoline engine, the reasons typically include:
- Clogged air filter
- Clogged fuel injectors
- Blocked manifold
- Leaking oil
A car or truck burning too much gas wastes fuel and costs you money. Schedule a visit with Christian Brothers Automotive Schertz for a solution today.
