Reliability, problems and repair of the Mitsubishi 4G63 2.0 liter engine.

The most famous, popular and iconic representative of the Mitsubishi Sirius 4G6 series (the family includes 4G63T, 4G61, 4G62, 4G64, 4G67, 4G69, 4D65 and 4D68) appeared in 1981 and replaced the previous inline four-cylinder 4G52 engine. It is based on a cast-iron cylinder block with two balance shafts, covered with a simple single-shaft cylinder head with 8 valves,which was later replaced by a more modern 16 valve with the same SOHC configuration, and since 1987 the 16 valve DOHC was used. These heads were equipped with hydraulic lifters and do not require valve adjustment. The diameter of the intake valves is 33 mm, the exhaust valves are 29 mm.The timing belt is driven by a belt, the average belt resource is about 90 thousand km.
In parallel with the naturally-aspirated engine, since 1988, the turbocharged and most famous Mitsubishi engine, the 4G63T, has been produced; it is the turbo version that most motorists associate with the name 4G63.
The production of the two-liter Sirius continues to this day by third-party manufacturers under the Mitsubishi license, while the Japanese company itself replaced this engine with the next generation of 2 liters. motor - 4B11.

Mitsubishi 4G63 engine tuning

Camshafts. Turbine on 4G63

The easiest and most affordable way to increase the power of the atmospheric 4G63 is to put the shafts. Our choice falls on camshafts with a phase of 264/264, to which we add a cold intake, a 4-2-1 exhaust and firmware. This will allow the motor to build 15-20 hp. and acquire a slightly more sporty character.
For turbocharging atmospheric 4G63, you need to buy a connecting rod-piston group, liners, pallet, head, head gasket, turbine, intercooler, intake manifold, ramp, injectors, gas pump, exhaust, ECU, engine mounts, everything from Evolution, weld the exhaust manifold, assemble and adjust, as a result we get near-Evolution power.
Alternatively, you can simply buy a Mitsubishi RVR Turbo engine, with TD04 and swap it, the Evo motor will not be installed easily and simply, improvements are needed.

The 4g63 power unit is one of the most popular, massive and well-known internal combustion engines of the Mitsubishi concern of the Sirius 4G6 series. Its very first representative appeared back in 1981 and, with minor modifications, continues to be produced to this day. Those motorists who seek to buy a 4g63 engine from Japan do so not only because of its more than 30 years of glorious history, but also focusing on the excellent technical characteristics of the unit.

Technical capabilities

Throughout its existence, the inline 4-cylinder engine has enjoyed unprecedented popularity. In terms of sales and technical improvements, it can be called the Mitsubishi record holder, and indeed a very reliable and resourceful unit.

In the engine device, the developers applied:

• 2 counterbalance shafts installed in antiphase;
• single-shaft 1-valve cylinder head until 1987;
• 1987 2-shaft 16-valve cylinder head;
• timing belt drive;
• cast iron cylinder block;
• throttle valve;
• hydraulic compensators;
• nozzles.

It was this configuration that contributed to the widespread use of the 4g63 internal combustion engine. Owners of a fairly wide range of car models can buy this unit in Moscow or in another region, the list of which is presented in the table.

Possible problems

One of the design features of the unit often becomes its problem. Lack of lubrication on the bearings of the balancer shafts leads to their jamming and belt breakage. As a result, a malfunction leads to malfunctions in the timing drive, then the cylinder head, etc. There are times when the owners have no choice but to buy a Mitsubishi 2.0 4g63 bu engine for replacement, because they missed the problem. To avoid malfunctions in the balance shafts, it is necessary to monitor the quality of the oil used and the condition of the belt.

Import of units under a contract

The quality of consumable fuels and lubricants affects the operation of hydraulic lifters, idle speed regulator and injectors. That is why it is better to buy a contract one to replace a worn-out 4g63 unit. Its price will most likely be higher than that of a used one with domestic mileage, but there will be no malfunctions caused by the use of low-grade consumables.

Our company will help to buy a contract motor 4g63, as well as any unit without run across the Russian Federation. Just fill out the order form on our website or place a request over the phone, and we will take the best offer for you.

GTI is an abbreviation for Gasoline Direct Injection, which means direct injection of fuel into the combustion chamber on a gasoline engine. At its core, such an engine is a mixture of the more common diesel and gasoline engines.

GDI engine: principal features.

From the diesel engine GTI received, which is capable of supplying fuel to the injectors of the combustion chamber under a pressure of about 5 MPa and the principle of fuel injection at the final stage of compression. It is also worth noting here the increased compression ratio in the cylinders, which is not characteristic of conventional gasoline internal combustion engines.

From the gasoline engine, the GTI received, first of all, the type of fuel used - gasoline, and also spark plugs.

As a result of the synthesis of these two systems, the GTI found the following modes of operation.

Principle of operation.

On everyday, measured city trips, the lean fuel mixture enters the last compression stage and is subsequently ignited by the spark plug. This mode of operation on a lean mixture only at low loads is due to the fact that a lean air-fuel mixture with an increased compression ratio can lead to overheating of the internal parts of the cylinder and such bad moments as glow ignition and detonation. It is for this reason that in conventional gasoline engines the compression ratio does not exceed 12 units, in contrast to diesel engines, where it is about 18.

During intensive urban and suburban high-speed trips that do not require a sharp increase in power, the fuel in the classic (stoichiometric) mixture for a gasoline engine enters at the intake stage.

If you need a sharp start, GTI works in two of the above modes at once. First, at the intake stage, an over-lean mixture is supplied, which is not capable of igniting from the hot elements of the cylinder (glow ignition), and at the last stage of compression, an additional portion of fuel is supplied to it, which generally increases the engine output, but at the same time excludes detonation.

The main pros and cons of the GDI engine.

Pros.

The following advantages speak in favor of using GDI engines:

1. increased compression ratio of the air-fuel mixture, at which destructive processes such as detonation and glow ignition are avoided;
2. the ability of the engine to operate in excess of the lean mixture without loss of power (the result is significant fuel economy);
3. reduced amount of emitted carbon dioxide and other harmful substances into the environment by reducing the amount of fuel burned.

Minuses.

However, due to the use of highly loaded and complex mechanisms in such systems, their owners still have to put up with:

1. higher cost at the stage of purchasing a car;
2. higher maintenance cost, since more complex fuel equipment requires more qualifications from the service personnel. Including consumables and spare parts will be more expensive.

Perhaps this situation will change in the future, but for now it is as it is: any additional comfort and pleasure from driving a more powerful car, in comparison with those in the adjacent lane, requires additional investment.

The Mitsubishi 4g63 engine is a four-cylinder engine designed for installation in passenger cars. It was first introduced in 1975 on vehicles such as the Mitsubishi Galant and Lambda. Then it was called G62B, after which the G63B appeared. Unlike its predecessor, it had a larger working volume, a different cylinder diameter and a different casting on the block.

In 1980, a new version of the engine appeared, including a mono-injection, as well as turbocharging and 12 valves. It was mounted on passenger cars, namely the Lancer EX2000 and Galant Lambda. The next stage in development began in 1984, when an inverter version of the motor was introduced, equipped with 8 valves. After 1988 the line of motors was renamed and the new version became known as 4g63. Compared to its predecessors, it had increased power and caused less damage to the environment.

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

In 1993, significant design changes took place. A modification appeared that had a unique method of attaching the flywheel to the crankshaft by 7 bolts. In parallel with the new one, the old version with 6 fixing bolts was produced. The motor has been produced by MITSUBISHI MOTORS throughout its history. Tightening global environmental standards have led to the fact that the production of 8 - valve versions of the engine has ceased. The last modification, equipped with an injector, was assembled in 1993. A similar version of the engine with a carburetor remained in serial production longer, due to its high reliability and low price.

In 1995, a modification that had a 7-bolt mount was called 4g63T. By the end of 1997, the 6- and bolt-on version of the injector and turbocharged engine was finally discontinued. In 2003, the engine received a number of improvements and was supplemented with the MIVEC system.

Specifications

The Mitsubishi 4g63 engine today is one of the most popular four-cylinder in-line internal combustion engines. It has a number of technical characteristics:

• The weight is 160 kg.
• Cast iron is used in the production of cylinders.
• The power system belongs to the carburetor or injection type.
• Engine power reaches 109 horsepower at 5500 rpm.
• The number of cylinders is four.
• There are 2 valves per cylinder.
• The piston stroke is 88 mm.
• The cylinder diameter is 85 mm.
• The 95th gasoline is used as fuel.
• Fuel consumption reaches 13.9 liters per 100 km when it comes to combined cycle operation.
• An oil change is made every 10,000 km.
• The engine resource is 200,000 km, according to the manufacturer's information, but in practice this figure can more than double with proper care.
• The power unit has specific features, for example, it has two balancing shafts installed in antiphase. Thanks to them, there is an almost complete elimination of vibrations that occur when operating at maximum speed.
• The 4g63 engine can be mounted on vehicles in which both longitudinal and transverse installation of the power unit are provided. This feature makes it possible to use the engine not only on full-size sedans, but also on compact cars intended for movement in urban environments.
• The motor number is located on the left-hand side under the exhaust manifold. To see it, you have to use a mirror.

Over the years, the power unit has established itself as a reliable and durable element of a car, regardless of the presence of turbocharging, mono injection or an injector.

Modifications

As mentioned above, over the years of its existence, the 4g63 motor has been improved and produced in various modifications, for example:

1. 4g63T, a feature of which was the presence of a turbocharger and a system that includes 12 valves. It had a fairly high level of reliability and durability, but was not widely used due to problems with the turbine used. It was often mounted on a sports vehicle. The power unit could produce up to 300 horsepower, which provided the cars with high dynamics.
2. It appeared in 1986 and used a gas distribution system called DOHC. Its presence made it possible to improve the power characteristics of the engine. This version fully complied with the strict requirements of Japanese environmental variety legislation.
3. 4g63 with four valves on one cylinder. This option was equipped with a modified gas distribution system called SOHS. The distinctive features of this type were high dynamic performance and low fuel consumption.
4. The 4g64 appeared in 1993 and included a 7 bolt mount flywheel. The characteristic features of this modification are the improved injection and the fuel injection system. Some Chinese manufacturers continue to install the 4g63 engine in their vehicles even today.

Citizens who purchase a vehicle with a similar power unit highly value their car. The motor has high reliability and maintainability.

Thanks to the special design, it is possible to tune the engine. Craftsmen wishing to improve their power unit should know that power can be increased in various ways, for example, using modified shafts, installing a turbocharger from 4g63T, using spare parts from a sports version, or installing a direct-flow exhaust system.

How reliable is the motor?

The 4g63 engine has a long service life and practically does not cause problems to its owner. Its use will save a large amount of money spent on maintenance and repairs. Despite the high level of reliability, the motor tends to fail over time. It is characterized by several problems that can be quickly eliminated without contacting a specialized car service, for example:

1. Vibration over time. The cause of this problem is the balance shafts, which do not receive enough lubrication when under high load conditions. If you do nothing, then the vibration can increase significantly, the shafts will eventually jam. Repair consists in replacing worn-out components and thoroughly lubricating rubbing parts in the future. In such a situation, it is recommended to replace the engine mountings, as vibration can also damage them.
2. Unstable turnover. The cause of such problems is a faulty temperature sensor, injectors or throttle valve that requires cleaning. When troubleshooting a problem, the most difficult moment is diagnostics, since it is not possible to use a computer in most cases.
3. An unexplained knocking noise occurs on an engine under load. A similar phenomenon occurs after 50,000 km of run. The fact is that hydraulic expansion joints are subject to natural wear and tear and become unusable over time. The motor begins to malfunction, and the characteristic knock plays the role of a harbinger of more serious problems. Problems can be eliminated by replacing worn parts. To prevent such problems from being observed in the future, it is required to use high-quality oil and replace it every 10,000 km.

The described malfunctions occur most often after prolonged operation of the motor. To prevent their occurrence, you need to carry out regular maintenance, monitor the operation of the engine and diagnose when the first signs of failure appear.

The power unit is not difficult to repair and the motorist can perform all the necessary operations on his own. The motor is not suitable for low temperature operation. If the thermometer drops below -30 degrees, then it is not recommended to start a car equipped with 4g63, since difficult starting in such a situation is quite common, therefore it is not recommended to use it in severe frost.

For proper operation over an extended period of time, it is necessary to fill the engine with only the recommended oils. If we are talking about a 4g63 engine, then it is necessary to use a lubricant with the following marking.

Grease	Characteristic
0W-40	It is great for working in extreme conditions. The oil has features, namely, a stable base, a small amount of additives, a long service life of additives, immunity to high temperature conditions, a decrease in the amount of heat generated, a strong protective film, as well as an easy start of the engine in frost.
5W-30	Well suited for engines installed in vehicles operated in urban environments. It ensures stable operation and prevents premature wear if the power unit has been idling for a long time, is in a traffic jam, operated when traveling over short distances and in conditions of high dust content in the environment.
5W-40	It has a low fluidity and flash point. Its use will avoid the formation of deposits that negatively affect the operation of the power unit. There is no need to flush on a regular basis, since such oil does not have the property of clogging the engine.
5W-50	It can be used for both a new engine and a power unit with a solid mileage. This grease is suitable for all seasons and provides reliable protection against early wear and corrosion. The lubricant has the property of restoring the performance characteristics of the engine components, thanks to the antioxidants included in the composition.
10W-30	Well suited for all-season use. In the manufacture, special technologies are used, as well as natural substances based on paraffin. It is able to significantly reduce the level of toxicity of exhaust gases, is not subject to oxidative processes, does not leave rust stains, prevents the formation of carbon deposits on various engine components and parts, and prevents premature wear.
10W-40	Suitable for a car enthusiast who wants to ensure stable engine operation in any climatic conditions. The oil contributes to economical fuel consumption, resists oxidation and forms a minimum amount of soot.
10W-50	Includes both mineral and synthetic substances. The use of such a lubricant increases the time intervals at which it is replaced. It has the property of significantly increasing the service life of the car, protecting against the deposition of unwanted compounds on the metal elements of the engine and producing cooling during operation.
10W-60	This lubricant has a high viscosity and contains components that have a beneficial effect on seals. Its use is recommended for engines that have previously undergone significant wear. The grease is capable of eliminating a variety of deposits formed in a high-mileage engine.
15W-50	It is a fully synthetic oil suitable for both gasoline and diesel engines. It includes three esters supplemented with the latest additives to ensure maximum performance. The lubricant is well suited for modified or sporty versions of the engine.

All types described can be used in the 4g63 engine at the request of the motorist or due to the prevailing circumstances. It is recommended to refill the engine with new grease every 7000 - 10000 km. The motor will intervene up to 4 liters, but when replacing, you should not pour in more than 3.5 liters. To do everything right, you need to perform all actions in accordance with the following algorithm:

1. Warm up the engine by letting the vehicle idle for a while.
2. Wait until all the components of the internal combustion engine have completely cooled down for 30 - 40 minutes.
3. Select a suitable container for the used lubricant.
4. Unscrew the drain plug located on the bottom of the oil pan. To avoid spilling old oil, you need to unscrew the plug with a key, then carefully remove it with your hands, substituting a container into which the working off will pour with a strong stream.
5. Wait 5 minutes for all the grease to leave the oil pan.
6. Fill in new lubricant through the top filler neck. When performing this operation, it must be remembered that a complete replacement is impossible. In any case, there will be about 3-4% of mining, which will not affect the operation of the internal combustion engine.

The drained grease is checked for contamination and unwanted impurities. Its analysis will determine whether the engine needs flushing or you can perform this procedure later.

When refilling, it is imperative to use a dipstick. First of all, 80% of the required volume is poured, after which the remainder is gradually topped up to the desired mark. Finally, a new oil filter must be installed.
