Folgendes tritt bei meinem Fahrzeug auf! Ibiza AFN 324 TKM, die letzten 6TKM mit wegen Defekt der Einspritzpumpe mit zu früher Pumpeneinstellung gefahren! Pumpe wurde zwischenzeitlich ersetzt; Problem nunmehr Weissrauch beim Kalt und Warmstart! Vermutlich hat es die ZKD erwischt, welche ich kommendes Wo-end wechseln will! Nozzles are in good condition.

It's strange that the white smoke only appears when the vehicle is in a specific position! For example, my parking spot has a slight incline. If I park the car facing downhill, I see white smoke early on, but if I park it the other way around, there's no white smoke. icon_eek.gif I've tested this for the last three days, and the result is always the same.

'Can anyone explain this to me? What could be the reason for this??? The valve timing and top dead center are perfectly accurate! There is a slight coolant leak, but it has always been present! There is no oil in the coolant!'

Well...

White smoke is evaporated water (sometimes also unburned diesel fuel).

The water always flows downwards. If the "downwards" direction leads to a place where it doesn't enter the combustion chamber, there will be no smoke. However, if the water enters the combustion chamber, it will produce smoke.

If I knew that for sure, I would always park it in a way that prevents it from smoking. Because water not only creates funny puffs of smoke when starting, but it could also cause more serious damage.

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

... there was another T.

I don't know what the f*ck it was.

The important question of whether it's water or diesel can be easily answered by smelling it.
