How do you fix a blue smoke from a diesel engine?
Clean The Engine. A clogged cylinder head can cause blue smoke. To clean it, remove the valve cover, and do the necessary cleaning. Also, clean the drain back holes carefully and recheck and reassemble them. After all of this, wait for 2 or 4 more days for the remaining oils to clean away.
What causes blue smoke from diesel exhaust?
Blue engine smoke is the rarest type of smoke emanating from a diesel engine. The presence of blue smoke is an indication of burning oil. Blue smoke should not be ignored but is common when starting an engine in a cold weather. The oil thins out when it is cold and some could escape into the cylinder and be burnt.
What does Blue smoke indicate on a diesel engine?
Blue exhaust smoke in a diesel vehicle could still mean oil is being burned, but it could also mean the engine oil is being atomized. This could be caused by: High engine oil levels. Worn out piston rings.
Can a faulty diesel injector cause blue smoke?
Constant blue smoke on a turbocharged diesel is unlikely to be caused by worn valve stem seals. Instead, the problem is more likely to be: Diesel fuel contaminating the oil. This may be caused by faulty injector pump and/or lift pump (which allows engine lubricating oil to mix with the diesel).
What does Blue smoke indicate?
Blue smoke can often look like grey smoke at first. But if you notice a distinctive bluish tint, it may signal that the engine is burning lots of oil. This could be due to worn engine components like piston rings, valve seals, or PCV (Positive Crankcase Ventilation) valves.
Can a bad turbo cause blue smoke?
If your car has a turbocharger, a blown-out turbo may be causing the blue cloud behind your car. A blown-out turbo can be identified by a broken or damaged oil seal. In this case, oil gets sucked into your engine’s combustion chamber. There, oil mixes with fuel and leads to blue smoke.
Can a blocked DPF cause blue smoke?
Blue smoke coming from your exhaust or DPF during regeneration comes from the burning of engine oil. This means that valves or piston rings may be worn out and allowing oil into the engine, or that you’re putting too much oil into the engine.
How do you fix blue smoke from exhaust?
How to Fix Blue Smoke from Exhaust
- Remove Excess Oil. The simplest fix is to remove some oil from the system.
- Clean Engine. If the engine hasn’t been cleaned in a while, it’s time to take a look at it.
- Replace Piston Rings.
- Fix Turbocharger.
- Replace PCV Valve.
- Repair Valve Seals.
Can a bad EGR valve cause blue smoke?
The exhaust gas recirculation (EGR) valve might be sticking occasionally and ti can give you blue smoke, when it sticks open it allows in spent exhaust gases which interfere with the combustion process but usually gives other symptoms like rough idle and possible EML warnings.
Does Blue smoke mean blown head gasket?
The most common sign of a blown head gasket is exhaust smoke. White smoke indicates that your car is burning coolant that is leaking into the cylinders. A similar problem is indicated by blue exhaust smoke, though this is a sign of oil leaking from the gasket.
Can Turbo cause blue smoke?

What does white smoke coming out of the exhaust mean?
The white “smoke” is likely steam, which should disappear after the engine and exhaust system warm up. If it does not, you may have a leaky cylinder head gasket, or a crack in the block somewhere. The blue smoke is from burning engine oil. The most common causes are worn piston rings or valve stem seals.
Why is there blue smoke coming out of the crankcase?
The blue smoke is from burning engine oil. The most common causes are worn piston rings or valve stem seals. Another cause coul be that your crankcase ventilation valve is malfunctioning.
What does it mean when your engine is smoking black?
Black Smoke. Black smoke is caused by excess, unburned or partially combusted fuel, or conversely by inadequate air supply to your engine. In either case the fuel-to-air ratio for your engine has been altered significantly.
