Passat B5 116KM 99: Oil Presence in Intercooler Lines - Impact on Turbine Efficiency & Renovation

I have a passat b5 116KM 99. I have a question about the presence of oil in the intercooler. Should it be there? I heard that if it is not a clear amount, it is not a problem. does it also require immediate renovation and does it have any impact on the turbine's efficiency? I noticed that there was dust or sand, rather dust with oil, it worried me. I will add that I have no problems with the engine, I know that the turbine is on the "descent" but the engine still has power (5 people 190 km / h but it was not the end of it yet possibilities in addition is a station wagon) it does not smoke in black or gray blue-well, maybe slightly, but it's a negligible amount, please give feedback-advice!

well, theoretically, the whole system should be without oil, but in practice it is impossible, for example due to odor or oil vapors getting through the turbine seals ...
in any case the system must be tight! each insensitivity is dust in the inlet and pressure losses in recharging!
ps. The fallen turbine pours oil in most cases, but it does not cause a drop in power - unless the blades are broken

ok! thanks for the opinion and advice. looks like I'll have to disarm the front again

a small amount of oil is normal, I would not touch a small hole in the IC, you can try to patch up with poxipol or other strong glue I would not panic with turbawa and if I do not take the oil engine, I would not bury anything

Turbine pouring is standard, if I do not "take" a dose of oil, I would recommend driving

with this disarming, I meant the intercooler itself, otherwise it is impossible to get it out of there?

you take off the bumper and you have access

The intercooler is made of aluminum and the small hole can be nicely soldered
And if there is so much oil that after leaving the car for 8-10 hours, you have a few drops on the floor, such spills are not from pneumothorax, but the turbo is pouring.
I do not recommend riding on a "incident" turbine, because it can do more harm than save some money ... the rotor is not balanced and has more and more vibrations.
I had a similar action with the GT20 at home and I replaced it immediately - as it turned out, the rotor had 3mm of play already: /
As for the intake system itself, if someone has a free pneumothorax and a healthy turbo, the system is 100% dry and clean - that's what I had at home until the first piece started to end now it is true that the 2nd GT20 is already sitting, but I did not clean the system.

As for the amount of oil, so far I can not say anything because, first of all, I have the car for a short time, about 2 months, the oil level was checked the day after the purchase and it was below the minimum level, of course, immediately replaced with the filter. on the website it turned out that the lower engine salt is screwed to the metal intercooler pipe !!!!!!!!!!!!!!! when replacing the timing, I welded everything up. after the amount of oil on the cover, it's hard for me to say how much it has been and is decreasing, while when changing the oil, the guy poured me a little bit of oil too much, about 150-250 ml, so it's like you don't know the amount of oil (I didn't know then either) but myself the engine will deal with such quantity. now it is max and I will start to monitor the level with mileage

I think you have an AJM engine and in these engines there is often a problem with "releasing". Download the pneumothorax and check if there is oil there. It is the tube that extends from the left-front corner of the valve cover facing the engine. Give an answer and then I will tell you what to do next.

ok, tomorrow I will look there and write it as it is.

hello! i took this wire off and there are traces of oil in there. any suggestions?

Was it a bit sweaty there or was the oil standing there, because it's a big difference?

rather slightly sweaty, I wiped the inside with a rag and it was soiled as if I had wiped the dust! that was the amount of this oil, i.e. traces of it (on a cold engine). but write if you can answer the second option and if you can, I will know for the future.

Well, it's not the pneumothorax's fault. It turns out, however, that the turbine is letting go. I used to have a pouring edema. I dismantled the valve cover and there is something like a bulkhead with round holes through which the gases come out. This bulkhead did not fit tightly with its sides to the walls of the cover and along these walls the oil flowed into the emphysema. I sealed the contact areas with silicone and the oil is gone.
