Perhaps all owners of domestic (and not only) cars have heard about such a structural element as crankcase protection, but not all of them know what it is and why it is necessary. In today's article we will talk about where the VAZ 2114 engine protection is located, how it is designed and what functions it performs.

Crankcase protection VAZ 2114

What is protection

Structurally, engine protection 2114 is a metal casing that protects the engine crankcase (essentially a container with oil) from damage when hitting protruding solid objects (for example, large stones).

The absence of this protection, as well as its being in an unsatisfactory condition, can lead not only to oil leakage (which is the most favorable option), but also to complete destruction of the engine due to its sudden wear.

For this reason, you should always check the condition of the engine protection after hitting obstacles when you return home, and if oil leaks appear on the ground after the collision, then immediately after the accident. If it turns out that the protection is severely deformed, you should stop driving and call a tow truck.

The protective casing is located at the lowest point of the engine compartment (which is why all manipulations with it should be done from the pit for greater convenience), directly under the engine. Externally, as mentioned, it is a steel casing that covers the bottom of the crankcase, and therefore it will not be difficult to find it.

Additional protection

But there are several important recommendations in this regard.

1. Do not use low protection, after installation of which the distance from the element to the power unit is less than 3 centimeters. This is due to the fact that the element can sag. Consequently, when hitting a hard object, it will bend and damage the crankcase.
2. Additional protection effectively copes with impacts under the floor, but poses a potential danger in frontal collisions. If during such an impact the usual protection falls from its mounts and the engine also ends up on the ground, then the additional one helps ensure that the engine remains on it and is directed into the cabin. This could result in serious injury to all people sitting in front.
3. If there are good roads in your city and if you live there regularly, there is no point in additional protection. It is designed for difficult road conditions.
4. Additional protection for the engine crankcase is relevant for a city with more or less good roads if you lower the car. Being close to the ground, a simple collision with a stone can lead first to damage to the sump, and then to breakdown of the engine itself.

The procedure for changing such an element is quite simple and does not require professional skills and knowledge. Therefore, you can completely do everything yourself. You only need an inspection hole and a set of keys to dismantle the fasteners.

When to replace and what protection is better to choose

Replacing the engine protection is required if there is a fairly strong collision with an obstacle and it becomes deformed. You should immediately remember that in this case it loses all its protective qualities and, moreover, becomes dangerous for the crankcase itself. So, if angular places concave inwards appear on the protection, then the next time you hit even a small obstacle they can be pressed into the crankcase and seriously damage it.

Thus, a severely deformed crankcase guard is a good reason to replace it. The presence of oil leaks on the ground does not play any role in this case - it is better to be safe once than to replace the car engine later.

Among the protection versions available in car dealerships, two good replacement options should be given preference:

1. Sheriff is a domestically produced security device manufactured in St. Petersburg. It is made of high-quality steel 2 mm thick and completely copies the original VAZ protection (while surpassing it in strength and service life). As an additional safety element, it has plastic wings that protect the space around the motor from soil and dirt. In addition, an important advantage of the Sheriff protection (both in comparison with the original protection and with protection from other companies) is the presence of two service hatches - for changing the oil and for changing the oil filter, which allows you to perform these operations without dismantling the protection itself.
2. Titan is another protection produced in Russia. It is made by stamping from solid sheets of hot-rolled steel 2.5 mm thick, which makes it superior in reliability to welded analogues. Its design also copies the “native” protection 2114.

How to make a replacement

If the engine protection is damaged during a collision with an obstacle, it should be replaced.

It is done in the following order:

1. Raise the car on a lift or place it on a pit (to provide convenient access to the lower part of the engine compartment).
2. Unscrew all fasteners of the old protection and remove it.
3. Clean the area between the guard and the crankcase if there are traces of dirt on it (if necessary, you can also replace the oil filter).
4. Place the new protection in place and secure it with fasteners.

Thus, the entire process will only take a few minutes.

Speaking about replacing the crankcase protection, one cannot fail to mention such an issue that worries many drivers as installing additional protection. It is designed to provide essential protection against damage when driving over very rough terrain and to ensure that even in very severe collisions with obstacles the crankcase will not be deformed.

At the same time, if you decide to install additional protection, you should definitely remember the following:

• if you live in a metropolis or just a city with a very good road surface, rarely travel long distances and never travel out of town on dirt roads, then installing an additional casing does not make any sense - it will simply “hang like a dead weight”, bringing no benefit ;
• if the additional protection has a height of less than 3 cm (that is, its bottom is 3 cm or less from the crankcase), then it is better not to purchase it, since in a very strong collision it can bend and damage the crankcase;
• if the car is lowered and the roads in the city are not of the best quality, then installing additional protection is highly desirable (perhaps this is the only situation when the presence of another casing under the crankcase is necessary when driving in urban conditions).

At the end of the conversation, it is worth recalling once again that the crankcase protection is not just a metal pan, but an element that protects the engine from failure due to oil leakage. That is why its condition should be checked periodically, and if it is severely damaged, it should be replaced immediately.

Mounting the VAZ 2114 engine to the body

Have you started to notice a strange knocking noise coming from the engine compartment? When driving along

Does the sound appear on a rough road with potholes and bumps, but disappears when accelerating or on a flat road?

Most likely, the engine fasteners are broken, which means it’s time to look under the hood. And if the knocking is accompanied by strong vibration of the body, there is a problem with the engine mounts. What are they and what are they for?

The VAZ 2114 car is equipped with three rubber cushions, two of which support the gearbox, and one serves as a support for the engine.

The direct purpose of rubber supports is to reduce vibrations. When the car moves, strong vibrations occur, transmitted from the engine to the body. To make the ride as comfortable as possible, and the driver not to be distracted by extraneous noise and jolts, airbags are installed.

Without rubber softeners, driving a car would be like riding a cart, just as noisy and shaking.

Engine mount malfunctions

The main damage to a pillow is loss of elasticity. The support is made of rubber, which loses its properties with prolonged use.

This is due to constant loads accompanied by changing weather conditions (cold, heat). In the future, the pillow will begin to deteriorate: it will crack and delaminate.

To prevent destruction of the rubber support, it is necessary to inspect it regularly. If damage is detected, the part should be replaced, otherwise strong vibration and extraneous knocking will be felt in the cabin, which will soon affect the operation of the engine.

It is better to replace the airbags in a timely manner than to later spend money on expensive repairs or purchasing a new engine.

The cost of engine mounts depends on the manufacturer, the minimum price for the front support is from 600 rubles, the rear and left ones are 500 rubles each. Average prices start at 1,200 rubles for the front, and 900 rubles for the rear and left.

It is possible to buy a set of three pillows from 3,500 rubles.

To replace engine mounts at a car service center, you will be asked for 1,500 rubles, but you can replace them yourself.

Replacement

As already mentioned, there are three rubber supports on the “fourteenth”:

1. front;
2. left;
3. rear

Front cushion

• It is necessary to drive the car onto the overpass and make sure that it does not move. To do this, put the handbrake on and engage first gear.
• We remove the crankcase and engine protection, freeing access to the support.
• If the car is not new, to make work easier, all fasteners should be treated with anti-rust solution, and before assembly, all bolts should be cleaned with the same solution.
• Raise the engine slightly using a jack. It is recommended to place a wooden beam or board between them to prevent damage to the part.
• We carry out the lifting very carefully, avoiding damage to the fan housing and radiator.
• On the body cross member we find a long bolt connecting the bracket to the support and unscrew it.
• We unscrew the mounting bolts connecting the support to the engine block.

VAZ 2114 engine protection and installation methods

As you understand, crankcase protection on the VAZ 2114 is necessary in order not to damage or deform the crankcase itself. What is this crankcase? Essentially, this is a container or pan where the engine oil is located. Now it becomes clear why the condition of the crankcase needs to be monitored with special care. Otherwise, an oil leak will occur, the engine will require crankcase replacement at best, and a major overhaul or complete replacement of the power unit at worst.

Installation of crankcase protection VAZ 2114

Installing crankcase protection for VAZ 2114, VAZ 2115, VAZ 2113, Lada Samara 2 The risk of destruction of the crankcase or body of a VAZ 2113 when overcoming obstacles, parking on one side on the curb or a sudden collision with objects falling onto the road from a truck is quite high, so the installation protection is one of the first operations performed on a purchased vehicle. With front eye mounts, the guard covers the extension cord shock mounts and the rear arm mounts of the front control arms. In addition, protection covers the engine from water, dirt flying out from under the front wheels or when driving on the deepest roads. But don't think it's a defense. it is a panacea for all ailments. If the impact is strong enough, the sheet will bend and transfer some of the energy to the device.

In addition, the protection increases the ventilation of the engine compartment, which can lead to overheating of the 2114 engine, especially in hot weather. Security settings are usually more helpful than harmful. However, this will naturally protect the stamped engine crankcase oil pan from damage or deformation due to small objects, and will not allow the oil pickup pipe to bend and push out engine parts without lubrication. But you must choose your protection carefully and carefully.

READ Which Engine For VAZ 2114

There are many knockoffs and very poor designs that are cheap but do not have holes for engine compartment ventilation or access to the oil drain plug or front suspension. If after installing the protection you notice a deterioration in the performance of your car, it must be removed and replaced with another one. It is better to choose more expensive, but tested and certified products. After deformation from the impact, the protective sheet may begin to touch vehicle parts, such as the VAZ 2114 engine oil pan, as indicated by a corresponding vibrating sound. In this case, the protective sheet must be straightened; otherwise the oil pan may be damaged. The guard is usually made of cast iron (in rare cases duralumin) stamped sheet about 2 mm wide, with mounting eyes and ventilation holes, as well as access to the crankcase and crankcase drain plugs. Work is carried out on a ditch or overpass.

Using socket 17, unscrew the front suspension mounting bolt. In the same way, unscrew the bolt of the front mounting bracket of the other extension . Use 19 wrenches to remove the front suspension bolt nut, holding the bolt from turning with a wrench of the same size. Similarly, loosen the bolt nut that secures the other arm. We use VAZ 2115 protection. If necessary, the hammer bends the eyes of its fastening.

Where is it located?

If you open the hood of your car, you will have a hard time seeing the protection. To do this, direct your gaze to the lowest point of the engine compartment.

Location

In order not to torment yourself and your eyesight, approach the car from the other side, that is, from below. It is under the bottom that you have to work with the crankcase protection.

When replacement is required

If the old device no longer copes with its direct responsibility, that is, it has become deformed and is as close as possible to the pallet itself, immediately begin the replacement procedure.

When the position of the protection approaches the sump, the slightest collision with even a small bump can lead to the fact that the element that initially plays the role of protection itself will cause damage to the engine crankcase.

What to choose?

When choosing new protection, it is important to pay attention to the individual characteristics and features of your particular car.

The design of the selected element directly depends on the type of body, the gearbox used, the engine and other parameters. Therefore, when going to an auto parts store, collect all the necessary information.

Sheriff

Based on the experience of VAZ 2114 owners, devices from two brands are excellent for this model.

1. Sheriff. Despite the foreign name, it is actually a company from the Russian city of St. Petersburg. To make the protection, the manufacturer uses high-strength steel 2 millimeters thick. The design of the element completely replicates the parameters of the factory device, but has higher reliability and durability. Plus, the Sheriff device is offered with auxiliary wings made of plastic or metal. They allow you to additionally cover the engine space from dirt, dust and other “pests”. Another important advantage of Sheriff devices is two hatches. One is for replacing the filter, and the second is for draining the oil. This will allow you to change the oil or oil filter without removing the protection.
2. Titanium. Also a Russian manufacturer that uses hot-rolled steel to produce protection for the VAZ 2114. The thickness of the element can be up to 2.5 millimeters. The popularity of the company is largely due to the fact that for production they use hot rather than cold rolled products. This has a positive effect on the performance characteristics of the part, which are superior to analogues made from cold-rolled steel. Titanium uses stamping, that is, the protection structure is monolithic and not welded. Consequently, we get a durable, reliable design.

Replacement

Replacing the engine crankcase protection on a VAZ 2114 is not at all difficult. You don't need to be a professional mechanic to handle this task.

1. First of all, you need to remove the old device. To do this, place the machine over an inspection hole or lift it with a lift. One way or another, you should end up under the car.
2. Now examine the structure to see what nuts and bolts hold it in place. All found fasteners are dismantled, after which the protection is easily removed from its place.
3. If you have the desire and opportunity, do a little “cleaning” of the space. Removing the crankcase protection allows you to get to some components - the same oil filter. It is quite possible that the time has come to replace it or change the oil in the crankcase. This is a good time to perform such procedures.
4. Now take the new piece you purchased and secure it in place with the new fasteners. If the old bolts and nuts are in good condition, clean them and use them for the new element.

How is crankcase protection installed on a VAZ 2114?

To perform installation, you do not need to have professional skills. Every motorist can cope with the task. To do this, you need to perform a number of actions:

• remove the second plate. The vehicle must be placed above the pit and raised using a jack;
• Next, you need to familiarize yourself with the design features. The plate is held in place with bolts. It is necessary to find fasteners and dismantle the steel sheet;
• It is recommended to clean the tray after removing the protection. There will certainly be dirt at the bottom of the power unit. It is possible that after removing the steel plate you will need to change the oil or filter;
• After “cleaning” the lower part of the power unit, it is necessary to install and secure a new sheet. You can use old as well as new bolts, depending on their condition.
