Why do not work EP6 engines

Spoiler

EP6 engines that enabled the best developments of "egg-head" engineers of BMW and PSA are definitely good. However, as it is not surprising, at many even quite "young" Peugeot and Citroen Motors EP6 work unstable and noisy, do not develop the power, "slaughtered" during acceleration, consume too much fuel and oil. After a relatively small mileage, "Flew Phases" timing, on dashboard The error "AntiPollution System Faulty" lights up ... In almost a new car, the cooling fluid temperature sensor can "turn out", which leads to incorrect operation of the motor and replacing the thermostat. Frequent oil leaks add their flue. The main potentially dangerous places are the valve cover laying (especially if the oil flows into the candlestones and corrosive the tips of the ignition coils) and the housing oil filterGasket vacuum pump, Electric oil pump valve.

With a rare oil change and especially when operating an EP6 engine with a reduced oil level fails, the mechanism of lifting valves. There may be options. Either "covers" the motor itself, which moves the valve lifting shaft, or the worm pair of the motor with the shaft is mechanically wearing. Look in the photos, the mechanical wear of the worm drive and the gear of the valve lifting shaft shaft looks like.

Error P2178, indicating overly enriched mixture, can appear for many reasons. But basically, it is of course, pollution of oil Channels CHC.

EP6 valves are covered with nagar, especially on the net on turbo EP6DT valves, errors P0087, P0313, P1336, P1337, P1338, P1339 and 1340 | Peugeot | Peugeot.

To eliminate nagar on the valves, it is necessary to act dramatically, cleaning the valve manually. Another problem of EP6DT turboads - scored all the same sediments of the old oil tube, in which oil is fed to the turbine. When the oil ceases to flow to the turbine, it is "covered."

As for problems with the GDM phases, first of all, it is necessary to correctly determine the source of the problem.

"Drink Blood" can still be the mechanism of lifting valves or worn bed of camshafts.

Of course, first of all it is necessary to elementary check the oil level! EP6 engine due to its complex GDM system is very sensitive to the oil level and "sausage", if not enough "only liter". Most often, the timing phase is shifted simply due to the stretched chain. Nothing amazing. On the chain itself without tears you will not see, the impression is that it is intended for a bicycle "Friendly". Could not put at least a double row ... for EP6 motors worse than a rare change motor oil, widely practiced on dealerships. The heart is bleeding when some kind of cute girl on Peugeot 308 come to us, which was held by the dealers, the service book with which is neatly filled, but at the same time it merges not just exhaust oil, and 2-3 liters of thick black Substances, more reminiscent fuel oil ... It is possible that the oil did not change the oil at all. Or changed every time.

On our modest look, 10,000 kilometers - the limit of the resource of the engine oil, no matter how good it is. In terms of driving in Moscow traffic jams, oil is desirable to change in general thousand through 8 runs. At least once a year you need to change the candles. There are a lot of living examples when people were "scored" for a guarantee and independently changed the oil. One of our grandfather-client on the 308th fawn, engaged in the replacement of oil in his own garage on the old habit, thus drove 170 thousand, and, which is amazing, his motor is still working as a clock!

Conclusion from all the above suggests simple. If you bought new car With the EP6 engine and want it to serve for a long time, "score" for a guarantee (anyway during the warranty period nothing happens) and change the oil every 8-10 thousand kilometers. Oil into the EP6 engine is desirable to fill only Total 5W30 INEO ESC.

Hello, the car heavily accelerates (tupit). For harsh pressed On gas, when driving, after not a big delay, the turnover increases and the thrust lacks. Increased gasoline consumption by 20-25 percent in the city (more than 13 liters). Gasoline 95, filled 98, no difference. In the morning it starts well, turns do not swim, the engine works smoothly. On the diagnosis, the dealers said to change the candles and rinse the nozzles, did not speak about the errors. I read the forums, it does not help, more like the electromagnetic valve and the grid in the tank. Mileage 90000. Tell me what it can be.

Need a diagnostics of the engine.
I recommend to turn the ignition to the angle. Only it seems that the engine is constantly working at the later ignition. Therefore there is no power and big flow. This may be due to a large nagar in the combustion chamber - the degree of compression due to this artificially increases and detonation occurs, due to which the ECU reduces the CHAS. As a rule, until the engine is heated - the power is normal, after heating - the power drops.
When the ECU comes to the minimum value of the Woz, and the detonation continues - the check is ignited.

Peugeot 308, 2008. Gasoline engine. VF34E5FWF55293696. There is no difference in cold and warm. Detonation did not notice. Check does not light up. Diagnostics drove specifically to the dealers of Peugeot. I believed that their scanner should show something. Nothing intelligible did not say.

Hello, perhaps I agree with colleagues, I think the first thing (the cheapest) it will measure all the engine indicators such as: compression in cylinders, fuel pressure, and exhaust toxicity, or at least the first two points. For these parameters, you can say about the viability of the engine. Also, the problem may arise due to the faulty automatic transmission I advise you to check it too, with some faults it spends a lot of engine power for internal needs.

Moscow, Ford Focus St.

Thank you, I'll do it.

Transmission this type On your car is very sensitive to operating conditions and maintenance. In the cold season, it must be warmed, in the summer you should not overheat.
Often requires checking oil level and replacement. Checking the level is not less than 20 thousand km run.
A frequent problem of this kind is the clogging of the hydroblock, failure electromagnetic valvesthat change to identical to another manufacturer.
First of all, pay attention to the gearbox, spend it maintenance, replacement of oil, cleaning. Next, make the diagnostics of its modules.

It is alarming your words about increasing revolutions with an insufficient acceleration, because you are about the power of the motor's motion, it is precisely at acceleration, so this testifies to the clutch slip, if the car is on mechanics or faulty automatic transmission.

The box has already changed on the bu (old often stood in emergency mode) With the replacement of oil, no difference noticed. On the computer diagnostics Boxes of problems have not been detected.

* Answer of this user is not expert

The computer is not a wizard. If the motor turnover is growing, and the speed does not increase, this is the problem of exclusively transmission, and not a motor.

I didn't quite rightly wrote about turnover, I think the turnups correspond to the transfer, compared with another brand of the machine. Regarding, growing and does not go.

Good day! Nevertheless, the cause of a malfunction is not in the engine, and you should look for it in the checkpoint, you set the gearbox similar how to choose? Also checked the level of fluid, possibly automatic transmission from another motor (she has a different gear ratio, hydrotransformer etc.)?

Rostov-on-Don, Kia Ceed

Hello, automatic transmission with Peugeot 308 2010 120l.s. The oil changed. The engine works just like with an old box, absolutely nothing has changed.

Condensate is a liquid that has passed from gas to a liquid state. Water in the engine will inevitably cause its damage - it will start rust. A B. winter time, under reduced temperature, water turns into ice, why the engine freezes. This may cause the cooling system nozzles or a cylinder head simply burst. Therefore, the appearance of condensate must be taken with due attention.

The condensate in the engine may look like a plaque or a small amount of whitic color foam, formed on the lid of the neck for the oil bay. This is a sign that there is water in the system. Its presence can alert a motorist, as similar signs can signal about certain problems. Abundant formation of foam can speak of a damaged strip in the head of the cylinder block, or about the attachment of antifreeze into the oil system. With such problems, the engine is often overheated. But if foam is a bit, in such cases, as a rule, it is not worth worrying.

Why is this foam formed in the engine? It remains on the engine after it cools out and is the result of the mixing of oil with water. As a rule, after a short time after starting the engine, this raid will be washed from the valve cover, but it can remain on the neck for the bay of oil. Does it say about the need to replace oil? Not. The amount of water in it is not so much to reflect on his quality.

In addition to the engine, condensate can be formed in others. automotive systems. For example, in the muffler, it appears from a sharp drop temperature. If the water appears in the gas tank - the first thought may often be that she fell there with gasoline. But this is not the only reason - if you leave the car warm, condensate may also appear. Special fluids will help to cope with this problem - water removers from the tank. They convert water in such a way that it turns into easily burning compounds. It is enough to use them just once a year. Condensate may also appear in the body due to temperature differences. The most optimal solution in this situation will be the use of special protection against corrosion.

After the trip, the air in the crankcase cools and its volume decreases. As a result, an additional wet atmospheric air is suused in the crankcase. In the further cooling of moisture condenses on the walls of the engine.
Condensate accumulation promotes short trips when the engine does not have time to breathe.

Why emulsion appears in the engine

The substance of white color with a yellow tump on the dipstick, under the lid of the oil-tank neck indicates an impurity in the engine oil of foreign liquid. But where exactly appears an emulsion in the engine and why does this occur mainly in the cold? Consider the main causes and methods of diagnosing faults.

Emulsions are formed by two unsuccessful fluids. In most cases, one of the phases of the emulsion is water. In other words, when motor oil and water mixed in the engine, in the pallet, on the dipped, the lid of the oil-tapping neck you will find a white and yellow flare. The reasons for the appearance of the emulsion in the engine is only 2:

Getting into the coolant oil, part of which is water. The leakage of antifreeze manifests itself not only by the emulsion, but also by a decrease in the amount of coolant in the tank, an increase in the oil level in the pallet;
In no case continue to exploit the car if you have found an emulsion on the dipstick. In such a state, the oil loses its lubricating ability. No less dangerous to enter the engine oil into the cooling system, which is why the likelipatibility of engine overheating is large.

The formation of condensate on the lid of the oil-tank neck in the winter season.

White raid on the covered neck

Many drivers are frightened, seeing white emulsion on the inside of the cover. But in most cases, their concerns are unjustified, since the flaw occurs due to the features of the engine in the frosty time of the year.

Moisture getting into the ventilation system of crankcase gases is a natural process. But when operating a car in the warm season, she has time to evaporate. With the onset of frost moisture is actively condensed on all cooled surfaces. When driving the engine, this moisture is completely evaporated from the surface of the heated parts. But since the lid of the oil-wave neck in frost does not always have time to warm up, condensate accumulates on its inner part. Water drops, mixing with oil pairs, forms yellow emulsion.

In other words, the main reason for the emulsion on the lid is short car runs, during which all the details of the engine do not have time to warm up. That is why such a plaque owners most often notice in winter, late autumn and early spring. If you have discovered an emulsion on the lid of the oil-tank neck, but at the same time the oil is in normal condition, it is not worth worrying. It is enough to wipe the lid and periodically observe the condition of the oil in the engine.

To reduce the amount of emulsion, periodically overcome by car a greater distance than a few kilometers from home to work and back. At the same time, we are extremely advisable for a long time to warm the engine at idle.

How can antifreeze get into the oil?

Breakdown gBC pads. It is extremely rare cause of a malfunction in the production marker. Much more often, a loose fit of the cylinder head to the BC becomes the consequence of engine overheating. The gasket weakening zones appear due to the deformation of the GBC, BC. It is in such places that the antifreeze is a breakthrough from the engine cooling shirt in the oil circulation channel. Also, the cause of the leaks of the conjugated surfaces can be the use of elongated bolts, poor-quality milling / grinding of bollard planes, incorrect order and moment of tightening of cylinder bolts.
Erosion of the cylinder block. The poor-quality coolant is capable of devouring the blocks of cylinders and the GBC. The consequence of such aggressive behavior is the crater near the circulation channels of the coolant. If the erosion zone is spreading in the direction of the oil circulation channel, then over time, this will lead to the weakening of the gasket of the GBC and the formation of an engine emulsion.
The crack between the oil circulation channels and antifreeze. The cause of microcracks, through which when the engine is heated, mixing occurs, most often in the engine overheating.
Grinding heat exchanger. The node is designed for efficient cooling oil and maintain the thermal balance of the engine. On some cars, the oil cooler of this type is a real headache. First of all, it's about opel owners, in particular, auto models with Z18XER engines. The problem of the emulsion on the dipstick, in the coolant tank on such engines is a common structural defect of the heat exchanger.

How to determine why antifreeze gets into the oil?

Pretty rarely mixing coolant with oil occurs unilaterally. It is more likely that by finding the emulsion on the dipstick and under the valve lid, you will find traces of oil in an expansion tank.

In search of the cause of the emulsion in the engine, we recommend going through the smallest resistance, starting checking from easily accessible aggregates. If an oil exchanger is installed on the car, inspect its housing on the subject of leaks of antifreeze, oil fifumes. These symptoms can serve as an indirect sign that the cause of a malfunction is in the cooler.

Having found a white emulsion on the dipstick and leakage of antifreeze in the initial stage of the problem of the problem, you can restrict ourselves to the engine washing by N-multiple oil replacement. Even cheap mineral-based products can be used for such purposes. But even it is important to know how not to buy counterfeit.

If the entire filling volume of engine oil has turned into an emulsion, without complete disassembly of the engine can not do. At the same time, it is necessary to blow the channel lubrication channels crankshaft, oilball piston group. The emulsion can clog the channels, which will lead to the sad consequences of oil starvation.

BC defecting, block head and gasket

After removing the GBC, carefully inspect the gasket and the flushing planes. Weakening zones, which become the cause of mixing oil and antifreeze, are usually clearly visible on the old gasket.

If the gasket does not cause complaints, most likely, a microcrack formed into the GBC or BC. In the article on the replacement of the cylinder block, we told how using kerosene you can check the BC at home. If possible, we recommend using the help of professionals. As practice shows, only checking on the crimping stand can reliably determine the fact of the leakage of the sleeves, oil circulation channels, coolant.

How to deal with emulsion?

Do not warm the engine for a long time idling. First of charge, the crankcase ventilation system is blocked at idle, Secondly heating on idle is very slow. It is necessary to start the movement after a short warm-up (as well as advise the operating manuals). If you suspect a breakdown of the cylinder head head and gas or antifreeze in the oil system, then for this you should watch a radiator of a heated car for bubble, as well as a freezed engine crankcase for a significant emulsion in the crankcase. On the valve lid, the emulsion disappears when the engine will adequately work under load - i.e. Riding without frequent stops, such as the country highway at speeds above 80 km / h.

If the abundant emulsion on the oil probe is detected, then it is a reason to take care of the engine in more detail, it is pretty warm and make diagnostics aimed at finding possible problems.

Also increased emulsion formation will be if the crankcase ventilation system or crankcase gases are made not forced, but simply hose hanging down from the engine cover. ATTENTION: Making businesses to the crankcase ventilation system, namely hanging the hose into the atmosphere, significantly reduces the service life of the engine oil due to its contamination as vapor of fuel and water and the sediments of the resin and other fuel combustion products. Therefore, if you are all the same, the interval between the oil changes should be reduced.
