After changing the oil, smoke came out of the exhaust pipe: reasons for what to do
You need to contact the automatic if you changed the oil in the engine and smoke came out of the exhaust pipe, where specialists will diagnose. If there is no experience in repairing the engine and fuel system, it is advisable not to try to fix the breakdown at home - there is a risk of making things worse.
After changing the oil, you can see quite thick smoke of different colors: from light to very dark. Disappears when the engine is warm enough, but the problem cannot be ignored. If the car owner changed the oil in the engine and smoke came out of the exhaust pipe, then this is a sign of a malfunction.
Source of the problem
Smoke is evidence of traffic disruption. Available in light, blue or black.
When the internal combustion engine warms up, the problem usually disappears, but this does not mean that you can forget about the malfunction - the motor is clearly not in order. By the color of the exhaust, the motorist will know how serious the failure is.
The main problems
The engine in the car smokes after changing the oil for a number of reasons:
- The engine on a cold car starts with effort.
- The motor runs but is unstable. This is noticeable both at idle and while driving.
- Turnovers of transport change extremely sharply, sometimes spasmodically.
- Too much flow in the fuel system.
- Overfilled with oil when changing.
- The power plant is faulty, does not gain the required power.
Next, you need to find out how serious the problem was.
Blue smoke from the exhaust pipe
Exhaust fault definition:
- Blue - during the replacement, the oil was poured, the substance burns, and therefore there is smoke.
- Black is a sign that there is unburned gasoline in the system, which lacks oxygen. It is necessary to pay attention to the nutrition of the car.
- White is not smoke, but steam. The likely cause is condensation.
If a motorist changed the oil in the engine and smoke came out of the exhaust pipe, this may indicate both one sign of a malfunction and a number of difficulties that need to be resolved as soon as possible. Attention to transport must be paid until the problem becomes more serious, and the car is not out of order.
What to do
You need to contact the automatic if you changed the oil in the engine and smoke came out of the exhaust pipe, where specialists will diagnose. If there is no experience in repairing the engine and fuel system, it is advisable not to try to fix the breakdown at home - there is a risk of making things worse.
Produced by different manufacturers, but works about the same:
- Creates a protective layer on the rubbing parts of the motor. Mechanisms are less subject to wear.
- Cleans from various deposits and dirt accumulated during the operation of the car.
- Fills cracks and defects in metal. So the nominal size comes to its original state.
Additives do not eliminate the malfunction of the motor, but only help to keep the engine in working position until a thorough repair.
Why You Can't Ignore the Problem
When, after changing the oil, the smoke from the exhaust pipe began to bother, it was time to undergo a serious diagnosis. If ignored, many parts will be subject to excessive wear due to increased loads. This especially affects the main oil seals, and in the cold season, when the oil is thicker than usual, the load on the part will be double.
Blue smoke indicates an overflow of oil into the engine, which leads to the extrusion of oil seals located in the crankshaft. Soon, excess will begin to pour out of all the gaskets, even from under the valve cover.
Smoke from muffler
If, after changing the oil, smoke appears from the muffler, the machine will begin to actively absorb the lubricant. As a result, the engine can run without the required substance, resulting in a costly overhaul.
Spark plugs also suffer. The part will fail when, after an oil change, smoke comes out of the exhaust pipe - a black coating appears on the surface. The engine speed will also drop, idle will become unstable.
The first warning signs are a signal that repairs should not be postponed. When the exhaust pipe smokes after an oil change, and the driver is inactive, you will have to pay at least 20 thousand rubles. in a car service.
