[Solved] Renault Megane 2 1.9 DCI 2006 - Engine Noise, Power Loss, Smoke & Ignition Issue at 230,000 Mileage

Hello, yesterday I was returning from Warsaw and I was standing in huge traffic jams on Wisłostrada when I freed myself and went on, I drove some ~ 150km and I was disturbed by a strange sound in the engine, I pulled into the parking lot, opened the hood and the problem disappeared, I continued my journey I drove about 40 km and noticed that the car does not have power, it collects less and less and even adds gas (after pressing the clutch, the revs jumped to the maximum) but it was temporary and the problem disappeared, I pulled to the side of the road because the car started to "scratch" strangely, I opened the hood and heard a strange hitting yes as if some sheets of metal and the noise came from the sides of the head or the turbine.
After a while, the car started adding gas at idle speed, so I quickly tried to shut down the engine so as not to turn the engine, unfortunately the car refused to obey and would not go out (starting and extinguishing with the button) I decided to throw it on the one and slowly move, the car calmed down but released a huge a cloud of smoke from the muffler (blue and white color) and the oil indicator came on, I added oil, I drove from a kilometer and this smoke appeared again and the oil indicator again. I know that it certainly does not burn the coolant because the condition is correct, but it burns the oil in huge amounts (before the failure there was not a drop of loss) I turned on the intercooler intake today and there are significant amounts of oil (photo) and there was oil in the vicinity of pneumothorax (the engine was dry before) please help what it can be. best regards

For example, a damaged turbine throws oil into the intake.

What about, for example, this tapping as if the badge hit somewhere?

The oil I get in causes knocking combustion.

Most likely it twisted the bushing, you had no oil in the engine anymore and it rubbed. Standard death 1.9 dCi.

Not necessarily because of the lack of oil, more oil has been sucked in and such chaust can bend the cranks (the liquid is incompressible). It is possible that only the knocking combustion (not fully revved) and the engine survived. It is also possible that, however, shells or cranks went.

So probably the engine to be replaced or dust the car and buy gas for only what the car is worth now

Check the turbine.
The price of the car is now very low.

Disconnect the intake, fill the engine with oil and start it as naturally aspirated. When it walks nicely and does not knock, it's just Turbo to do and wash intake.

A mechanic friend has just checked me and said that the turbo has fallen, I am in the process of disassembling the turbo, if I manage to change it, he will write if it helped. Greetings


Ps does anyone know how many bolts the turbine is caught in megane 2? two are definitely at the top and what next? After disconnecting all the wires, the turbine itself hangs, but it still sticks to something

I pulled out the turbo and here's what I found:

Turbo replaced and everything works
