    Hello,
    Can anyone tell me exactly how it is with this engine suspension in this scrap?
    The engine began to vibrate, "jump", jerk and evidently move in the chamber.
    I noticed the broken right leg (engine) of the engine:
    http://www.tomczesci.pl/index.php/produkt/545...a-silnika-peugeot-407-citroen-c5-hdi-febi.htm
    So I exchanged.
    The rear cushion was also damaged:
    http://sprzedajemy.pl/poduszka-silnika-partner-407-1-6-2-0-hdi-po-nr31247052
    Did not help.
    So I changed the gearbox cushion:
    http://e-katalog.intercars.com.pl/#/produkty/3019213433221-SAS8131981-poduszka-silnika.html
    Still nothing.
    The engine is trembling, when I press the gas pedal, I feel a blow as I let it go. The engine works differently, everything falls into vibration.
    Is there any pillow there? I can not see anything. On the other hand, the logic of the gearbox does not satisfy the engine's holding against forward-> rear forces. There is only gum from below.
    On the internet he also has such an engine cushion / paw:
    http://www.bazarek.pl/produkt/6339065/poduszka-lapa-silnika-peugeot-407-16-20-22-hdi.html
    But I do not see her in my car.
    Should she be in every 407 2.0 HDI? Possibly where?

    If you have already given all the new cushions (good quality) and still the engine "vibrates", I have a question whether the cushions are correctly fitted. Is the engine efficient, i.e. it burns on all cylinders, maybe it is already a high mileage. Check the cylinder pressure, it should be fairly equal in 4 cylinders. A small tolerance is allowed. Did you change the fuel filter.

    Buddy, and maybe see from another side maybe it is not entirely the fault of the cushions, as the clutch may lie somewhere in the beam of the suspension element of the chassis.
    The engine goes out normally and does not go out with a delay. It can also be the cause of Pressure in Cylinders, Timing and many other things.
    I was not long ago on such training of one of the big corporations and said just about a similar situation is not always the cause is the pillow said for the reason that there are many reasons, from the timing to the ending of the engine, the clutch of the wrong combustion ending the beam, etc.

    Gentlemen, I can recognize the incorrect operation of the engine from the smashing element.
    Usually, if something breaks in my suspension, it's hearing and feeling (where the vibrations are spreading) diagnoses the cause, the mechanical checking of the brech only confirms.
    The engine works very well, I have no doubts here.

    Evidently you feel something vibrate, during the transition from acceleration to engine braking something will jump (evidently as if the engine has moved) and when passing from braking the engine in acceleration is the same.

    Because the only element that I did not replace in the engine suspension is the right engine cushion (there is a cushion and such a paw - I replaced the paw on the service when replacing the pins and the control arm.) The cushion under the paw was considered efficient by the service staff. differently.
    I already mentioned the bottom cushion (2 hours of work) because the professionals did not take up because it was supposed to last half a day and cost PLN 400, and a pillow above the chest, which supposedly was efficient.

    Today I installed the camera under the hood (directed to the only element of the old not mentioned, i.e. the right pillow) and I find that this engine is terribly telepiece there.



    So I ordered a new one, it will be for tomorrow. We'll see.

    What still surprises me, why the engine is mounted on the right side with a cushion, a paw, the right side at the bottom of the sleeve, and on the left just above the chest such a cushion on which hangs, which does not give virtually no cushioning and stiffness to the sides and front back.
    A very strange philosophy.

    Those connecting the lower wachacz with the crossover? (if it's called a crossover in this strange suspension).
    I exchanged them three weeks ago.

    Hello,
    I thought I had a similar situation in the Ford when I started and released a certain click, I do not know how to accurately describe it, there was such a situation that the joint had a slight change in the steering knuckle front up back top down after unscrewing the main bolt holding the joint in the steering knuckle there was again putting the magler through other mechanics.
    After replacing the joint and hub on the skf, everything returned to normal.
    Try one more thing, go somewhere on the channel, pull the hand and try to move the front back first, slowly and then faster by touching the hand that you suspect may be defective, you can feel the slack in this way.
    Where are you from, maybe you live somewhere not far away.

    Listen up.
    Recently (about 3 weeks ago) I was in one of the better (and, unfortunately, more expensive) websites in my area, because I got pissed at the nearby for apologies for sleepers.
    The car hit the jack, it was bent on each side, then it hit the channel, there the same and finally a solid tug.
    Gentle soft joints / sleeves were found in the switches and knocked out lower pins. All these elements have been replaced, where they had to smash the front suspension slightly when replacing.
    No additional damage was found.

    As for this skipping, I would feel if it was skipping directly in the drive unit.
    The situation is that even when I am accelerating and pressing the clutch to change gear, I feel something fall on the rubber floor and twitch a few times. It is also visible on the film, when I press the clutch, the engine suddenly returns to its initial position, hopping a few times.
    I bet on 99% that it is a problem with the engine assembly,
    The thread was made because I wanted to find out why this engine is so strangely mounted, only on the right side and just hung on the left.

    So I exchanged the upper right cushion:
    Peugeot 407, 2.0 HDi 136KM - Engine suspension - the engine moves
    The culture of work has changed very much. After starting the engine, if it was not that it could be easily heard in the cabin, I would not know that it was working.
    However, I still did not fit the cushion above the gearbox.
    The old original also had such rubber bumpers to protect against excessive front-rear displacement. She did not have this.
    I noticed, however, that the cushion is adapted to mount fenders but they are not included in the set.

    I made them from old bumpers:
    Peugeot 407, 2.0 HDi 136KM - Engine suspension - the engine moves
    I still feel a certain click like a forest from acceleration to braking and vice versa, but this is a lot different than before.
    However, now I do not know if there is any oversensitivity, because the gearbox itself is not loose.
    Possibly, I still have to look for ideas, for the reason for less flexibility of the engine, because maybe there is a reason.

    It can be made of a dual-mass wheel and does not dampen as it should. Possibly set the engine on the cushions.

    The engine is already well positioned on the cushions. Nothing shakes, I do not get into the vibration of the entire cockpit as before, I can use the benefits of diesel, or how to blame and accelerate what is not necessarily everything to jump at once. Everything is fine from this side.
    The only thing that still puzzles me is, for example, I drive in 5th gear and accelerate, suddenly I release the gas pedal and the car begins to brake the engine.
    For some time, then, a slight jump is audible and felt (now as if it is simply on the gearbox because it is not loose).
    It's just that I have the impression that only a few years ago this jump was better suppressed or the motor was more flexible and such a sudden change of dose did not cause such a torque jump.

    Hello.
    Do you handle the problem of skipping / moving the engine with a sudden release of the leg from gas?

    I join the same problem, i.e. leapfrog. Release the clutch, add gas, change gear, tap with the team. Tiresome. Pillows changed to new, it gave a button.

    Drzasiek, you didn't originally change the right upper cushion because it didn't look worn out?

    Hello!
    I also join the topic.
    I replaced the complete clutch with a new hatch, all cushions except the lower one, but it looks good in addition to the gearbox because I thought there was a problem in it. Unfortunately, the same when adding and releasing the gas is a strong shift of the engine almost hits, when replacing the clutch everything was checked in the suspension and it is fine, the sleeves of the sleds have no sign of wear. Hands are falling !!! . I do not have vibrations.
    Only when moving forward and backward there are slight vibrations

    I also changed almost all the pillows and didn't get rid of the problem. From what many people write, only the original pillows get back into working order. I made this mistake that I bought replacements ...

    Have the driveshafts been checked?

    Half axles were checked, I replaced the left outer joint because it had play, while the inner joints have minimal play, practically imperceptible.
    I am wondering whether the box cushion should be so soft, because I did not replace it as a new part, but I bought it on the Allegro. Overall, compared to mine, there was practically no difference, one and the other were not torn, both have oil

    Maybe it is worth replacing the lower pillow, sometimes the appearance does not reflect its actual condition. Good advice, because it's a lot of work - replace it with the original one. Many people write that substitutes do not work here ...
