[Solved] Golf 4 1.6sr floods 3gar - it comes in 3 pots, floods candles, ditches

Hello
After firing for 1km the car goes well, then it starts walking like a tractor for 3gars, burning around 17-18
Injection exchanged for regenerated, we thought that it was because it burns 18 liters and smelled of fuel, candles are flooded on the 2nd cylinder,
I don't know what to do here, candles give a spark.
Do you have any ideas?

What about ignition cables? maybe there is some short circuit after warming up?

Replace the coil.

coil, cables. candles mentioned is still a problem.

Measuring compression pressure?

1 Cylinder: 12.3
Cylinder 2: 11.7
Cylinder 3: 11.9
4 Cylinder: 12.3

There are no spark errors in vagu, after unplugging the injection plug the engine operation does not change.

Hi, compression after oil test?

What are you raving about? Why should it change if the cylinder is not working? Since the compression is correct, there are no miracles - ignition system failure.

What are these nerves for?

Candles give a spark but in the air, inside the cylinder may be too weak or not at all. You have a double ignition coil and the spark jumps simultaneously in cylinder 2 and 3. Since cylinder 3 works, it means that the circuit closes and the spark from cylinder 2 flows somewhere other than the spark plug. Try swapping the ignition cable plugs 2 of 3 and see which one will not work then.

And change the injection places - maybe the injection is pouring?

Hello again, after checking everything, I noticed that the previous owner added gasoline to the oil and there was no carbon deposits on the candle, after replacing "Oil" for normal and changing candles, he walked normally again, after a few days the problem appeared again, I unscrewed the candles and on the 2nd cylinder as if someone in the mud drowned with debris (previously gasoline cleaned it in a sense) ...., after cleaning and putting on the car, it traveled 2-3 km and the candle was in a similar condition again. I will add that the engine on the first start after oil change, etc. buried as if diesel not fired 20 years ^^ and question what could it be ??? Because some say rings, while others that only some "Erasers" on the valves, I'm waiting for help.
Best regards.

Added after 8 [minutes]:

picture from the internet, the candle is like this one in the middle but I have 3 electrodes.

Candle evidently thrown away - flooded with oil.

What do you think, valves or rings?

What does that matter?
And so you have to drop your heads, so you have more work hours and the pistons on top.
Do not count on replacing the sealants on the guides and it will be good.
As I know life, the valves fly loosely in the guides and the replacement of sealants will not do anything.
The head to drop and to check the guides and valve seats or looking for another engine but it's hard to hit what oil does not take.

How much fun would it be if it were rings and how many valves ??

If that's true then search engine. But rather gasoline was added by itself through the inactive pot.

Rings, cylinder honing + head repair, burned candles with oil carbon deposit and had no spark.
