Why is there a smell of exhaust gases in the car when the stove is turned on

Signs in which you can suspect a breakdown of the exhaust pipe are as follows: collector bolts are poorly tightened, the gasket between the cylinder head and the exhaust manifold is worn out.

Often, motorists have problems with the vehicle. One of the common problems is the smell of exhaust gases in the car when the stove is turned on. First of all, you need to analyze possible malfunctions and correctly eliminate them.

Why does the car interior smell of exhaust gases when the stove is turned on: reasons

It is known that the products of combustion should exit the engine through the hood without causing problems to the driver, passengers, otherwise their leakage adversely affects human health.

Therefore, it is desirable to fix the flaw quickly, finding out the reasons.

Exhaust system leak

Signs in which you can suspect a breakdown of the exhaust pipe are as follows: collector bolts are poorly tightened, the gasket between the cylinder head and the exhaust manifold is worn out. In addition, there may be a lot of noise, vibration during engine operation.

All these violations lead to the appearance of exhausts in the car dealership when the stove is turned on.

Damage to rubber seals

This is the most common problem. Usually, the elastic bands fit snugly to the structure, but over time, the material wears out: tightness disappears, it can creak and burst. Therefore, when driving in a car with this malfunction, exhausts and moisture will leak through the damaged element, bypassing the filter.

Custom exhaust system

Tuning enthusiasts often direct the hood to the side or forward flow, and when this configuration is changed, combustion products can seep into the cabin.

Custom exhaust system

In fact, this system is deliberately tuned to resonance with the engine and is located in the area with the highest vacuum, so the exhaust gases are better off. It is easy to solve the problem - we install a standard exhaust.

How to fix the problem

Eliminating the smell of exhaust gases in the car when you turn on the stove is very simple. You need to act according to the instructions created specifically for this case:

1. We check the oven. First, we inspect the strength of the cylinder head connections, if necessary, tighten the bolts. We examine the exhaust manifold gasket for wear and tear, if necessary, we replace it.
2. We look at the extractor. It is necessary to fit the car on a flyover for a visual inspection of the bottom. While the engine is running, we diagnose the following elements: exhaust pipe, each muffler in turn, rocker boot. Depending on the complexity of the malfunction, we change the part or use welding to fix it.
3. We control the tightness of the pipes. In the absence of visible problems, you should carefully run your hand along the pipes - the flow of invisible gas will be felt immediately. We repair such damage using welding or sealant.

If, nevertheless, the nodes are functioning properly, the sealing gum is new, and the problem of the smell of exhaust gases in the passenger compartment cannot be eliminated when the stove is turned on, it is better to contact a master who has special equipment and training.
