Blue Smoke and Oil from Muffler in Toyota Avensis D4D 116HP - Turbo Regeneration Issues?

Best answers LABEL_AI_GENERATED

Why does a Toyota Avensis D-4D 116 HP smoke white when cold and blue during driving/acceleration, and is the turbocharger likely the cause?

The turbocharger is not the first thing to blame; the replies point first to compression loss, injector/fuel-system faults, or a problem with the crankcase breather system. A bad turbo would more typically cause weak boost and gray exhaust, while the whistle alone does not prove turbo damage [#16236622] One reply advises checking the air pipes and intercooler for leaks, and also checking whether oil is getting past the compressor seals by disconnecting the pipe to the intercooler; a lot of black oil there would be a real warning sign [#16236759] Another reply notes that these engines can suffer from head-bolt thread problems and worn rings, which can create high crankcase pressure and oil spitting, so a general engine repair may be needed before judging the turbo [#16235725] Because the engine also cranked longer in frost and smoked white briefly on cold start, a compression test and diagnosis of injectors/common-rail system are recommended first [#16236622][#16236759]

    Hello, I bought a Toyote with a D4D 116HP engine, theoretically the turbo is fresh after regeneration. I noticed that the pneumothorax that comes out of the engine lid and should be attached to the pipe (which is between the air filter and the turbine) is led out to the car. The second thing, when the toy car is cold and starts to warm up, it seems awful in white after a few minutes is ok, but when driving it starts to kick blue, usually during acceleration, but also blue smoke can fly at low speed. Is this a turbo already?

    I will say this - it will be faster to replace what has not been mentioned. The muffler and side mirrors certainly didn't fall.
    How much did you pay for this gem, because up to PLN 2,000 you can get it back by selling in parts for scrap metal.

    If the pneumothorax is disconnected from the pipe, you can suspect that the engine has scavenge and is large. Engine to be repaired. Have you checked the oil level in the engine?

    These engines have a problem with loose threads in the cylinder head bolts. Threads in the engine block too short and pulling out. Awaiting you for a general overhaul of this engine, Polish mechanics threaded the engine block for larger bolts and set the head again, I have no information how long such a patent can withstand, The second issue is pneumatic if it spits oil and a high pressure is created on the working engine (you can plug it with your hand for a moment) worn lubrication rings, but this must be checked after head repair.

    and how to eliminate that the turbine does not let oil to the muffler ??

    Oh, is oil still pouring from the muffler? Just oil :D There probably already someone put wooden pistons and put on "Alle_luja" :D

    I unscrewed the rubber from the turbine, there is no slack, the mechanic claims that the simering in the exhaust turbine could let go and let oil pass.

    So yes: the white color is only in the morning and appears after 2 minutes of work (kicks quite strongly for a moment and disappears). It's okay later. But when it warms up, the blue smoke will fly at slow times - while there is a lot of blue when accelerating.

    As for the turbo, in fact with a strong addition of gas you can hear the whistle along with the sound of how much the air is pumping (but it also speeds up well - feel the 116KM)

    Yesterday at -5 did not fire from the shot, only a few seconds I had to spin and cast it for a moment, after which it already worked well.

    Emphysema is routed under the car and is behind the rear beam and I tell you that no smoke or steam is coming out of it. maybe a little oil drips sometimes.

  • Suspected crankcase ventilation causing turbo oil ingress

    I have a similar problem with my 2017 Toyota Rav4. While driving, she suddenly started to smoke very much and came into revolutions. The mechanic replaced the turbine and, during the test drive, it went into rotation again. The mechanic removed the hose from the turbine and there was oil. He says the turbine looks ok and the oil is most likely getting in there from a pneumothorax. I wonder if it could be a stuffy pneumothorax or something more. There have never been problems with firing or spinning. No sign, everything happened suddenly. The mechanic insists that the engine needs to be replaced and checked nothing else. I've already spent a lot of money and I don't know anything about the car.

Topic summary

LABEL_AI_GENERATED
The discussion revolves around a Toyota Avensis D4D 116HP experiencing blue smoke and oil emissions from the muffler, raising concerns about potential turbocharger issues. The user notes that the pneumothorax is disconnected, which may indicate engine scavenging problems. Responses suggest that the engine may have compression issues, possibly due to loose cylinder head bolts or worn lubrication rings. The turbocharger's condition is debated, with some suggesting it may not be the primary issue, while others recommend checking for oil leaks from the compressor seals and ensuring the integrity of the air intake system. A similar issue is reported with a 2017 Toyota Rav4, where oil was found in the turbine, leading to concerns about the engine's overall health.
