Why does my Nissan Patrol have white smoke?

Bad injector spray patterns have been known to cause white smoke too. This comes about when the engine attempts to burn through dribbling injector droplets when it’s not atomising the fuel correctly. Dribbling injectors tend to make the engine noisier than normal and also can contribute to black smoke problems.”

Is it bad for a diesel engine to have black smoke?

Whether or not is bad for your engine depends on what the cause of the black smoke is. A little black smoke is normal on a properly functioning diesel engine, but if the amount of smoke changes at different RPMs and loads you have an issue. Here are the things it could be and then we will go into what to look for and steps to diagnose the problem…

Is it possible for an intercooler to fail?

Intercooler failure is fairly rare, at least compared to failures in the plumbing between it and other components. All substances in this universe — at least those warmer than absolute zero, or negative 459 degrees F — contain a certain amount of energy in the form of heat.

What does blue smoke from a diesel truck mean?

Gray or Blue Smoke from Diesel Exhaust. Newer, low mileage truck owners can skip this paragraph, but many of us like to have a worn out beater truck laying around, or maybe your teenager bought their first car from a not-so-honest guy. Blue usually means one thing: you are burning oil.

Where does the intercooler go in a turbocharger?

An intercooler is a heat exchanger that goes in between the two turbos in a series turbocharge system, while an aftercooler goes between the final turbo and the engine. But whatever you want to call that radiator thing in your turbo plumbing, it plays an important role in helping your engine withstand the abuses of boost.

When do you get black smoke from the exhaust?

For instance, when we look at the diesel car, most times you will get a black smoke being emitted from the exhaust is the first moment the engine is switched on. Another time is when the weather is cold or when hard acceleration is applied. That said, in these three cases, the black smoke that comes out of your exhaust is often very thick clouds.

What does Blue Smoke mean in a diesel engine?

Blue Smoke in Diesel Engines Blue smoke is a sign that oil is being burnt. Puffs of blue smoke, often at the back of the engine, suggest it is burning deposits of oil. It is happening most likely because it is entering the combustion chamber.

Why does my diesel engine smoke when I accelerate?

Black smoke from a diesel engine when accelerating is not always a serious problem. Most diesel cars (if not all) emit a small amount of black exhaust smoke while accelerating. It takes some time for the engine system to develop enough revolutions (RPM) and power to burn the fuel.

What makes blue smoke from car when starting and when accelerating?

What makes blue smoke from car when starting and when accelerating? 1. Lots of Blue Smoke When Starting Cars (not Diesel): Bad Valve Seals. If you see blue smoke coming out of exhaust after you have parked your car for a while and the engine is not a diesel, the probable culprit is Bad Valve Seals. Each engine has valves that open and close.

Why do I have black smoke coming from my engine?

Black Smoke usually comes from a rich burn or carbon build-up. Meaning that it’s burning more fuel than it should be, or the engine is building carbon on the valves. If you see the blue smoke, we know that we are burning oil. So why is the engine burning oil?

What does it mean when you have smoke coming from your engine?

Billowing fumes almost always mean there’s something seriously wrong with your car. But the color of that smoke might help you understand what type of repair can help fix it. Many engine problems create abnormal or excessive exhaust smoke. In your engine, fuel is burned in each cylinder, creating exhaust gases.

What kind of smoke is coming from the exhaust?

What does it mean when your car has white smoke coming from the exhaust?

White smoke. Some white exhaust smoke is normal, especially when you first start the car. Condensation can turn to vapor, providing what looks like white exhaust. But excessive white smoke likely means coolant is leaking into the engine combustion chambers.

Why do I get blue smoke when I accelerate?

Otherwise that smoke on acceleration looks exactly like almost every colt I have seen from that era, they have all done it from bad valve stem seals AFAIK. You might be able to do a valve seal job with rope or air but a thicker oil should slow down the consumption a bit. Also probably a new PCV valve if it’s blocked.

Why does my Mitsibushi blow blue smoke when accelerating?

Old Mitsibushi’s have a bad habit of being oil burners. Drop the oil and try a thicker one. I had a colt once. They were very common to wear out the valve stem seals. The best way to tell if its that is to let the car idle for 2-3 min then give it a rev. It will blow a cloud of smoke.

What kind of smoke comes from a diesel engine?

Blue Smoke: 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.

Why is there blue smoke coming from the exhaust pipe?

Blue Smoke From Exhaust When Accelerating. When blue smoke is emitted from a car’s exhaust pipe, this usually indicates that a leak in the engine’s valve seals is allowing oil to leak into the combustion chamber where it is being burned along with the fuel.

Is it normal to have blue smoke from a diesel engine?

No amount of blue smoke is normal. A new engine may burn oil without any evidence of blue smoke because of the good compression it can burn oil cleanly. However, it is not acceptable for any engine to burn large amounts of lubricating oil. A great thing to do as a preventive for your diesel engine is a oil and fuel additive.

What causes Blue Smoke on a cold start?

Why does a diesel engine put out smoke?

and to make things a bit more complicated here, on a diesel engine it works similar but different.

This is why when diesel’s rev they put out a lot of smoke until the engine catches up.

Why does a turbocharger only produce boost when the engine is running?

For example, when rolling down hill, you don’t need to hit the throttle so the entire intake to exhaust path is pumping a smaller air mass. However, driving uphill will require you to open the throttle (give it gas), adding air to the intake.
