He wrote a little about something else as far as I remember.
The first power units of this family were born in 1975. They were intended to be installed on vehicles such as the Mitsubishi Galant. At that time, the engine had a working volume equal to 1850 - and cubic centimeters. The next version contained more fuel, had a different casting on the block and a different cylinder diameter.
In 1980, an engine was made, equipped with mono injection, turbocharging and having 12 valves. It was most often installed on the Lancer EX2000. The next step in development was 1984, when an injection version of the power unit with 8 valves entered serial production. After some modifications, this modification was installed on various vehicles from 1986 to 1988.

After that, the power unit was significantly changed, thanks to which the DOHS versions were born. Power characteristics have significantly increased, and the adverse effect of exhaust gases on the atmosphere has decreased. In 1987, they began to produce motors with 16 valves. They were a smaller version of the old modification, the cylinder head has not undergone any changes.
In 1993, the power unit underwent another deep modification, and a version appeared in which the flywheel was mounted on 7 bolts. In parallel with the new, the old version continued to be produced. Versions equipped with 8 valves were taken out of series production when environmental regulations tightened.
The latter type, which includes a carburetor, has not ceased to be produced due to its high level of reliability and affordable cost. It was installed on commercial vehicles until 1998. In the period from 1992 to 1997, the power unit was installed on both rally vehicles and city cars.
The mitsubishi 4g13 power unit has a number of features that determine its cost. These include:
The mitsubishi 4g13 power unit is used as a platform for creating a large number of modern 4G engines.
Some motorists have difficulty finding the license plate on the engine. To find it, you need to open the hood and pay attention to the gap between the manifold and the gearbox. There is a small loading on the block, which is an area of about 14 square centimeters. The required set of numbers is located on it.
There are times when they cannot be disassembled due to dirt. It creates tangible interference if the motorist has no idea where the number is. In such a situation, you will have to wash, and then start searching.
The mitsubishi 4g13 engine is quite durable and malfunctions are rare. With timely maintenance and repair, you can extend the life of the engine for several decades. However, certain problems arise with inept care. And if the breakdown is not eliminated in time, then it can lead to undesirable consequences and entail considerable expenses. Typical problems include:
The listed malfunctions can be avoided by timely diagnostics and monitoring of engine operation.
Despite the use of innovative technologies when creating the mitsubishi 4g13 engine, repairs can be made in a personal garage with some skills, knowledge, and basic equipment. The car enthusiast can eliminate some of the problems described above on his own.
The reason for the examination is extraneous noise, the smell of antifreeze or gasoline, as well as smoke from the exhaust pipe. If a malfunction does occur, then the driver on his own can:
The mitsubishi 4g13 engine is a reliable power unit, but even it needs high-quality fuel, original parts and regular maintenance.

Motorists who do not have the minimum skills to troubleshoot engine malfunctions should contact specialized car services at the first sign of a problem. It is necessary to choose organizations that have established reliable channels for the supply of Japanese auto parts directly from the manufacturer. The employees of such a service station will be able to carry out any type of repair or maintenance with the highest quality, quickly and at reasonable prices.
The durability and stability of the motor directly depends on the quality of the lubricant. If you choose the right oil, it will be possible to reduce natural wear and tear and make it as easy as possible for the motor to perform its basic functions. For the mitsubishi 4g13 engine, a lubricant is suitable, which is marked:
5W-20. The oil can significantly increase the service life of both old and new power units. It helps to remove previously formed carbon deposits from the components and retains its properties even under adverse conditions, for example, during cold start-up. During extreme operation, the lubricant forms a protective layer on the parts, which softens hard shocks as much as possible;
5W-30. This type is synthetic and is recommended for use in motors with high mileage. The oil retains its properties at both high and low temperatures. It is widely used for movement in urban conditions and includes a number of additives that provide additional wear resistance, increase the resistance of parts to oxidative processes and do not require frequent replacement;
10W-40. It is all-season and is used in both diesel and gasoline powertrains. The oil provides fairly effective protection against premature wear, leaves no residue when operating at low or high temperatures, provides resistance to oxidation processes and prevents the formation of soot on engine components.
The described types of lubricant have their own characteristics that must be taken into account by the motorist when applying. The right choice will allow you to get many benefits and avoid unnecessary costs.
The engine has become widespread due to its high power characteristics and reliability. It is used to install on:
The listed cars are very different from each other, but they have one thing in common, the mitsubishi 4g13 engine plays its role. It is assembled in different modifications and has certain characteristics that allow the machines to ideally perform the tasks for which they were designed.
Before us is the 4G13 engine of the Mitsubishi Orion family, with a displacement of 1.3 liters, originally from the 80s, developed for small cars, like the Mitsubishi Colt, Carisma, Lancer, Mirage and used in their simplified versions. The engine itself is simple, based on a cast iron cylinder block, with a cylinder head for 12 or 16 valves, and all these valves are on one camshaft (SOHC).
In the area of faults and shortcomings, the 4G13 engine copies the older 4G15, their description can be found here.
By and large, tuning such a small motor is a very strange thing and is designed only for the most ardent fans of your car. Nevertheless, since we have a reduced version of 4G15, then all the methods used on a poltorashka can be implemented here, the description of the 4G15 revision is here.
Car: MMS Libero 1999 onwards, 4g13 engine cb-1v body, carburetor, automatic.
The crux of the problem: Large oil consumption 1 liter per 1000 km, oil flows in the area of the sump, cylinder head, compression 12.5.
Option 1. In general, one car service said that a capital of the engine is needed, specifically, the replacement of kalpachs, rings, liners, boring of the shaft and block of cylinders, replacement of the piston well, and replacement of gaskets that leak. they take 20t.r for work, together with spare parts I figured out 35-40t.r
Option 2. Another car service said that only the replacement of valve stems, rings, replacement of old oil seals of gaskets that podtikayut and possibly replacement of liners is required. for work they take 6t.r, with spare parts it comes out 12-15t.r
Question: Advise what is the best to do? I myself think that with such a compression, there can be no talk of any boring and I tend more towards option 2.
The valve is not lapped. Most likely misses. See valve chamfer
PS: rings are purchased, gaskets are purchased, valve seals are purchased. wait for the report later.
master cleans piston: crazy:
that's what happened

in the order of actions.
remove the bottom, pull out the pistons, measure the cylinders, wash the pistons, knock out the rings and put everything back with new rings for about 3500-5000r.
dry the valves, pull out the valves, wash your head from coke (spending a lot of chemistry at the same time and time), clean the valves on the machine from carbon deposits (coke), lapping valves (I have 12 of them) 2400-3200 rubles. + cost of chemistry (xs about 1000-1500r) total: 3500-5000r.

Good health to all!
I drove to the Alt.Krai and all over again! I removed the fuel pump, the tank is clean, there is no dirt. I went to the diagnostics, looked at all the candles and armored wires - everything is in order. The gas pump showed a pressure of 3 atm.
Symptoms: cold wild vibrations! as they warm up, they go away and work normally at idle. The car does not run at all! More than 40 km / h does not accelerate! gas to the floor - she screams, but does not go. Even driving into the garage became a problem! She just rested on a 5cm nut and could not drive on it!
Can you please tell me what could be the reason?
kind people, they suggested that this happens when the 1st (small) catalyst is clogged. But is it on this car? I understand that he must go after the collector. And after the collector, I just have a pipe, then a corrugated muffler, then a large catalyst, which is made of mesh.
today I will try to post a video of how the engine works.
Increased oil consumption is a common problem for many Mitsubishi Lancer IX car owners. Most likely, a rare oil change at an authorized dealer is the culprit. Agree, 15,000 km. on one oil this is a lot. Therefore, in order to avoid this, it is better to reduce this interval at least two times.
But if you are reading this now, then this problem has touched you too. Let's try to fix this by replacing the piston rings and valve stem seals in the engine.

Remove the ignition coils, then unscrew the spark plugs.
2. Remove the outlet manifold.
3. Remove the cover of the block head, having disconnected before that almost all the connectors of the sensors:
4. Next, you need to remove the timing belt:
5. After removing the block head, carbon deposits and deposits on the pistons are clearly visible
6.They unscrewed the bolts of the oil pan (there are a lot of them, they were tortured to unscrew) and with a screwdriver they pried it off the block. Having removed the pallet, we saw that some garbage was hanging on the strainer of the oil channel ... Apparently the decay products of oil or something else. They are already missing in the photo.
7. Unscrew the connecting rod bolts and pulled out the pistons:
8. Clean the pistons and oil pan with a knife, kerosene, WD, carburetor cleaner and a toothbrush.
9. Clean pistons were put back. The sleeve bearings were quite good.
10. Next, they began to disassemble the head of the block. By the way, it is better to unscrew the inlet, otherwise it is inconvenient.
11. We removed the crackers with a decanter from a 12-valve 16-valve, slightly drilling a hole in it. But some of the crackers did not want to come out and it was inconvenient to crawl to the valve with this decanter. As a result, we used a homemade decanter ... very convenient compared to what I bought.
This tool is:
12. The main thing is not to lose or confuse anything:
13. Exhaust valves with very heavy carbon deposits:
14. Intakes are a little cleaner:
15. Carefully removed the valve stem seals:
16. Cleaned the head, rinsed with gasoline, dried, blown.
17. The valves were cleaned. They look much better now:
18.We rub the valves with a coarse and fine paste. This process takes a very long time, but it turns out beautifully. For comparison, the right saddle is ground in, the left one is not:
19. Then they put everything back together:
Addendum: I ordered original exhaust caps, but they did not fit during assembly. They returned them back to the store and ordered caps from another company, where the diameter of 9 mm was written. For the original, this information is not prescribed, because of this, the repair was delayed for a week.
After the first start, the engine worked like a tractor. But after 10-15 minutes everything became quiet and calm. Now I go to run-in no more than 3000 rpm. After 400 km of run, the oil remains at the same level.

The next step is to repair the 4g13 engine itself. It is usually divided into three types, depending on the complexity:
Good day to all! I ask you to help me figure out the reasons for the following malfunction.
There is a car Mitsubishi Lancer 9 2006 onwards, 1,3L, 82 hp. 4G13 16 valves engine, car mileage 170 thousand kilometers. At 120 t.km. there was a major overhaul of the engine (oil zhor was eliminated). Now, by the way, it also began to eat up, there is gray smoke from the chimney.
The client complains of a chaotically arising sharp loss of traction when driving on the highway, that is, it can drive normally for a long time, and then the car cannot even pick up speed when changing gear; claims that the difference is very tangible.
What was revealed during the diagnosis:
Scanner diagnostics revealed that the fuel trim is in a small minus (-5%), and the throttle valve opens not 100%, but 94.5%, and this is precisely the figure. I moved it anyway: 94.5%. I checked the TPS oscilloscope, there were no dips and noises in the signal.
Sparking at different speeds is normal, the shape of the spark is not distorted. The primary on the coils is normal, there are no dips / distortions.
Connecting a vacuum sensor gave the following picture:
Seemingly good painting and mechanics in perfect condition. But for these motors, the closing angle of the exhaust valve is 7 degrees after TDC! Here is a link to the official manual:
The deviation from the norm is 5-6 degrees.
I tried to raise the speed, take measurements, the picture changed, but did not add clarity to the situation:
There was an attempt to test the efficiency of the cylinders, I found a signal pin in the connector, but there just rectangular pulses were removed from it, and it seems to me that therefore the test did not want to be processed at all.
The inlet is checked for leaks - no leaks.
I did not check the fuel pressure, since the BN was changed, it did not help.
The owner himself checked the “non-motorized” reasons for braking: he watched the brakes, etc. When you open the lid of the gas tank, the vapors break out, and it puffs so much. The tank is not concave, there should be no vacuum.
I could not check the oil pressure, because in the conditions of my workshop it is almost impossible: there is no hole and there is no way to crawl there even with the wheel removed.
I myself believe that the problem is still in the pressure, since the knock of the hydraulic lifters and the appearance of a malfunction occur simultaneously. But I could not prove it in essence today, since the car looks absolutely serviceable. The only difference is that the picture from the vacuum sensors differs from the factory by the closing phases of the exhaust valves.
I ask you to express your opinion, otherwise I am sitting in limbo. Well, I agreed with the client that I will call you back tomorrow and share your opinion as well.
The 4G13 engine is a power unit manufactured by Mitsubishi. Quite a lot of modern engines of the 4G series have been developed on the basis of the installation. The applicability of the engine is quite wide and many vehicle models have received this unit.
4G13 is a popular Mitsubishi Motors engine. The engine comes from the 80s, with a displacement of 1.3 liters. Treat the power unit to the Orion series. Cast iron block, which is covered with a 12 or 16 valve head.
There are no hydraulic compensators, the valves are adjusted every 90 thousand km, the valve clearances are as follows: inlet 0.15 mm, outlet 0.25 mm (hot), inlet 0.07 mm, outlet 0.17 mm (cold).
The timing belt drive is belt-driven, the belt service life is 90 thousand km (it is advisable to change it earlier), if the timing belt breaks at 4G13, the valve bends. The engine power supply system is carbureted (for the first modifications), later the engine became an injection engine.
Technical characteristics of the 4G13 motor:
Mitsubishi Motors Corporation
6.4 liters for every 100 km of run in mixed mode
Mitsubishi carisma
Maintenance of the 4G13 power unit is carried out as standard for the entire line of 4G engines. The service interval, according to the manufacturer's standards, is 15,000 km. To preserve the resource of the engine, it is recommended to carry out the procedure for changing the oil and filter every 10,000 km of run.
Repair of the 4G13 block head.
Like all power units, the 4G13 has a number of flaws that appear throughout the entire production line. Let's consider the main ones:
Increased oil consumption. The malfunction begins to occur at a large development of the resource (approximately 200,000 km). Solved by replacing the oil scraper rings.
Vibration. There are two options for the problem - a malfunction of the pillow or an increase in idle speed.
High or floating revs. Throttle problem.
Difficulty starting the motor. The problem lies in the gas pump or simply flooded the candles.
The 4G13 engine is a fairly powerful and reliable power unit manufactured by Mitsubishi Motors. He loves high-quality parts and consumables, and is picky about fuel. Service is recommended every 10,000 km.

Repair of the Mitsubishi Lancer 9 1.3 4G13 (16V) engine can be major, or it can be partial. The type of repair is determined only after diagnostics by a minder. Partial overhaul of the Mitsubishi Lancer 9 1.3 4G13 (16V) engine may include replacing the GBK gasket, replacing valve stem seals, replacing valves. Partial repairs usually do not include removing the engine block, boring, grinding, liner, etc.
You should not decide to repair the Mitsubishi Lancer 9 1.3 4G13 (16V) engine yourself. People often come to the service who say - “my neighbor told me that I need to change the cylinder head gasket and everything will go away”. Of course, we can listen to the client and go to a meeting, but if this does not help in solving the problem, all responsibility will fall on the client, and not on the service minder who diagnoses and is responsible for him.

From experience - in systems where there is only a Hall sensor in the distributor, and the ECU controls the spark moment - with the correct installation of the distributor drive - the slider will not be opposite, but with a significant deviation from the contact of the first explosive wire on the cover. You stubbornly do not want to pay attention to the correct installation of the drive.
