You've noticed before...

...that when the spark plugs are pulled off, you can clearly hear the cracking of the spark in the candle channel when the engine is running?
I just ran into it, as I was on the track of my ignition dropouts again.
If it's wet outside and also when it's cold, I miss at least. One cylinder. Now I have just pulled the plugs one after the other and found that in the case of cylinder 6 this cracking noise is NOT heard. Even if I hold the plug against the ground, no spark jumps over, with the others this is the case.
So I think that there is a rather weak spark there, which does not ignite the mixture properly at cold start and damp conditions, only in the warm engine condition it is enough to ignite.
I'll change the cable and see what happens.

Another question. Are your tailpipes pretty rusty, too? I polished mine about 300km ago and now they look like an old golf diesel! However, consumption is ok, driving it short distance (approx. 7km) with 16-17l, so there is no talk of drinking. How's that with you with the rusty tailpipes?

Thank you and have a nice EM evening!!
