Heavy “slime” in crankcase ventilation hoses?
Hello,
I drive a 2001 Opel Astra G CC 1.6 16v, and I have a problem where the hoses coming from the throttle body are full of slime. I discovered this when I wanted to clean the throttle body and suddenly saw nothing but slime in the hose that leads from the throttle body, or rather from the valve cover, to the throttle body.
Back then, it was dry or just a little oily, but for the past two or three months, it's been slimy (I check and clean it almost every other week). The other hose that runs from the intake manifold down (right down on the valve cover) is also full of slime. The oil cap and dipstick are normally oily, and there's no sign of slime or cylinder head gasket damage.
I assumed that my KGE was completely dirty and bought a "new" used valve cover because they are tied together and the hoses are still filled with slime.
I drive the car every day for 8 minutes on the highway (to work), and otherwise mostly for short trips to the city center. It doesn't use water, and it doesn't suck in any air.
I'm at my wit's end and don't know what to do. I hope I can at least find someone here who can offer me an explanation or some help.

In the combustion of gasoline, in addition to CO2, there is also a lot of steam. Of this, a bit is always pressed past the natural leaks between piston and cylinder into the crankcase. There it cools off and mixes with the oil and the oil vapors which are sucked in again via the venting. This emulsion looks like this.
It’s normal and like that on every car.
If the engine is warm then the water evaporates and dissolves out of the oil. Therefore it is advisable to drive a longer distance again and again to keep the engine warm for a while. This naturally takes longer in winter than in summer because the starting temperature is lower, the winds cool more and heat is drawn off by the heating.
In this context, you can see if the temperature indicator is still high to its normal value, perhaps the thermostat is also defective and the engine is no longer really warm.
To go to the number safe but also observe the cooling water level.
You can clean as much as you want. If the crate doesn’t get warm when driving, it will always look like that. By the way… It’s total bullshit to suspect a broken ZKD! This looks similar but at best at 10% of the cars where the KGE looks like this!
Drive warm! Then the condensation water can also evaporate and the hoses are clean again. What’s 8 minutes? Your engine oil might come to 50-60°C in winter.
So it told me a worker from a free workshop, apparently also because of which the valve lid seal became leaky as the KGE was “cuffed”. Doesn’t this whole sneak the engine? I’m sorry about these stupid questions, had had 5 cars and none of them had such a slime. Do not want to use my half knowledge and “repair” something provisionally.
There is still a hose in the throttle valve, which is also filled with glue. It is sucked up by the engine. Isn’t it harmful to the engine or is it burned directly into the combustion chamber anyway?
It’s just supposed to go through oil fights. This mud is not really optimal now, but really cannot happen. The throttling valve is stretching, but that happens anyway.
In fact, the simmeringe had to be changed with valve lid seal. So your testimonial is 100%
By the way, the staff of the Free had not been so wrong. When the KGE is cloged, the Motro slowly builds up pressure. in the simplest case, only oil comes to the VDD. m worse fall on one of the shimmer rings of the crank.
Okey, thank you eddi for reply and help
If you drive short distances at this cold season and also you want to have a chubby warmth and the heating completely turned up, the engine is not really warm and it forms condensate in the oil, which normally evaporates.
Drive on the highway and 30 – 40 min (not full gas!) or wait until it gets warmer out again. Then the mud goes away.
This has less to do with Opel, the problem have many cars across the brand just in winter
I know that it doesn’t matter which manufacturer it is.
But without knowing the engine and its components, for example, I do not know whether there is a heater with this engine that should at least minimize the problem. And it could be broken, for example.
At VW there were retrofitting of the heating at the time with certain engines because there were engine damage.
Did I say anything to the contrary?
Engine’s up. Opel had no heating in this respect
Is it not harmful to the car? Zmd’s coming over to me so much. Now, no one who is constantly in the gas, go quietly and stop the short distances to work. In 15 min, hold cool water 90 degrees think that the oil temperature change looks different at only 15 min car ride. I think they’re right
Can also sprinkle the mucus as far as possible
Looks for me emulsion by condensate.
Too much short distance operation favors this.
Since I have nothing to do with Opel, I can’t write you anymore.
Take a look at this in an Opel Forum with like-minded people.
thanks for the quick answer first. I don’t know if these forums are still up-to-date or active as most entries are older than 6 years.
In the Opel Subforum of motor-talk.de you will surely find the right people.
It doesn’t matter what brand this is! Short distances have the more or less the same symptom of any manufacturer and model!
