What is Causing Car Exhaust to Emit Blue Smoke?

Does the engine of your car produce blue smoke? Don’t throw it aside. Usually indicating that your engine is burning oil, blue smoke is dangerous. Though it might not be a serious issue, have it looked out before it gets bad. Knowing what produces blue smoke might help you to know when you need Auto Repair in San Clemente, CA. Let’s examine the causes and their effects on your car.

Oil Leaks in the Combustion Chamber

Oil in the combustion region is a usual source of blue smoke. Oil spills past piston rings and combines with gasoline and air. The engine burns this combination to produce clear blue smoke. This can happen if piston rings wear down. Older engines with high mileages are more likely to do this. Leaving this problem alone might worsen engine damage, so examine the rings if you detect blue smoke.

Unburned Fuel in the Exhaust System

Fuel that isn’t completely burnt during combustion can sometimes produce blue smoke. Fuel might enter the exhaust system due to faulty fuel injectors or an unbalanced air-fuel mix. Blue smoke is unburned fuel. You may also find your car moves slower or uses more petrol. This might indicate that your fuel injectors or other engine parts require cleaning or repair. You could remedy it by getting them checked.

Turbocharger Issues

Perhaps your car’s engine is leaking blue smoke.  The turbo drives air into the combustion region, therefore boosting fuel burning. Seals on broken turbochargers might leak oil into the exhaust system. The oil burns producing blue smoke. Check the turbocharger if your turbocharged car generates blue smoke. Although Turbo problems might be difficult, early identification will help you save Auto Repair in San Clemente, CA costs.

Methanol Injection

Some high-performance cars inject methanol. Adding water and methanol this way increases engine power and cools the intake. However, a poorly set-up system might burn too much oil, producing blue smoke. Make sure your car’s methanol injection system works. Blue smoke often results from this less frequently.

Stuck PCV Valve

Your engine’s fuel system relies on the PCV valve. Jammed PCV valves tighten engine parts. This pressure might force oil into the combustion chamber. This causes oil to burn and emit blue smoke. Changing a jammed PCV valve is usually simple and inexpensive. If you don’t, your engine may suffer more.
