Peugeot 3008 1.6 THP Engine: Odma Modification, Intake Channels & Turbine Valve Issues

If it were only gases, then there would be no need to rewrite the pneumothorax. The problem is that large amounts of oil are released in the form of oil mist, which passes through the entire intake system and is then burned.

In addition, the engine has direct injection, so an additional problem is that there is a sinter of oil (coming from pneumothorax) on the valve stems and in the inlet channels of the head because only air flows there and not the mixture that washed this section of the system as in old gasoline.

I leave the matter of the flow meter because it is not in this engine.

A few months ago I was working on a pneumothorax in 1.6HDi because the oil was dripping from the intake system and the engine had just 50,000 driven. km. and it wasn't turbo's fault.

greetings

I will modify the pneumothorax.
0.7 L of oil for about 1000 km. Oil on the valve cover. It's hard to start the engine after a long idle time. Now, after parking the car, if it has to stand for more than 5 hours, I cool the engine down (the car runs at low speed for about 2 minutes and fires like new.
Pszemo1194 you are great.

Hello, I have the same problem, an oily line and oil consumption. I would like to order such modifications. Recently, I did a continuous route of 2700 km, I added about 1.25l of oil on the entire route. It was the cheapest Full Synthetic 5w30 because I knew it was getting something. Przemo1194 where do you live? I need to redo it and I have concerns whether I will do it as it should be. Possibly someone present will undertake it? I'm from the area of Tarnów. Greetings to all forum members.

Gentlemen, I do not contribute to the topic because I sold my 308 1.6 THP with great joy. Let me just mention that a moment before the sale I replaced the valve cover with a new one, but here I also made a modification, namely into the gas and vapor inlet which is in the cover, I put two wires into the pots that did a great job and captured the oil vapors very well and condensed back to the engine by gravity. Thanks to that, the cable that goes from the cover to the turbine was dry. Nevertheless, I diagnosed myself with the problem of flushing the oil on the rings and personally I did not want to break the engine to do it. Someone else has already taken care of it? Let me just add that the modification was also applied to the old valve cover with the gas output to the atmosphere.

Hello everyone, today, to be sure, I checked the compression pressure and the result of 16bar is practically minimal differences on each cylinder (a bit strange when the service shows 11-14bar) I will add that before changing the oil, I did a rinse, maybe that's why this result. It is possible that in my case it is enough to change the oil to the target good oil deal with the pneumothorax to further reduce oil loss.

Unfortunately not. Here, oil consumption is dictated not so much by its "burning" in the cylinder or the low Noack index (evaporation rate), but by the design of the rings, which were assumed by the manufacturer, due to its concept of the lowest possible rolling resistance. Rings are available for purchase, and more precisely a set corrected by the company from what I remember well Mahle. Instead of the OEM oil ring which consisted of a very delicate spring placed in a ring with drainage holes, which for a moment burnt and lost its properties, Mahle replaced this structure with an oil ring consisting of a traditional "harmonica" and it does its job. In addition, one should also mention the very quickly hardening valve seals, which release oil in huge amounts, which may manifest itself in e.g. oiling / clogging of the exhaust valves (a typical defect of BMW engines - in fact it is a BMW engine: code N14B16), which should also be replaced if someone will be having fun replacing the rings and removing the head. In addition, when the engine is ripped out, the cylinder honing should be done because it is very delicate and the oil has nowhere to stay on the cylinder bearing surfaces to fulfill its role. Their stroke was not too big because it also leads to oil loss and few people remember about it. If you do all this, plus the modification of the pneumothorax, or as Przemo wrote, you can reduce the consumption of the lubricant to zero.

Does the modification work

The replacement of the covers from Allegro helped; the engine was dry.

Hi everyone, I looked out of curiosity what kind of patent it is for this unfortunate pneumothorax? We reworked this engine from A to Z, so as I can see here some people don't feel up to such a modification, maybe you will be close enough to me. I invite

Moderated By T5:

regulation 3.1.10

, there you will find all contact and address information? We have a very nice patent, but personally I would add a catch can, because not everything will be separated by this sponge, and why bother with ecological problems later??

Hello. A very helpful topic. However, I have a problem with the vacuum created by the intake in this tube on the left. I disconnected the tube from the cover (I didn't change anything in the cover) and I didn't block the outlet with anything and the engine started throwing me a little. I read somewhere that this suction (quite strong) "draws" oil and lubricates the top. I also noticed that my valve began to slap during my attempt. Can someone explain it better. Like in BMW, connect this outlet from the cover in a way before air filter? Can you mount a suction pump?
I'm interested because it bothers me that from time to time the engine has some slight vibrations at a standstill and I'm trying to get an oil catch tank because there is a lot of water and in winter it smokes the most compared to others.

I have a question, przemo, Did you use a finger cutter to make a hole through? Please reply.

as you can see in the picture. I have made an isthmus like this but from what I remember it makes a small hole in the lid but it doesn't really matter.

So I don't need to make a hole at all?

I have this question. If one buys a new cover with a new air purge will the oil burning problem go away? Or will it not change anything?

Hey can such problems also occur in 1.6 VTI? I recently replaced the valve cover with a new one because the old one was leaking terribly and before that it was drawing oil I can't remember but about 0.2 per 1500km, now the car draws 1l per 1000km and I wonder if the new cover has caused me to draw oil through the air purge.
