I recently decided to remove the leads and apply some Förch copper paste to prepare for a cold winter with many short drives and was overwhelmed by the amount of water I found in the spark plug wells.
I did clean the engine using Autoglym motor cleaner and hosed it down with water (which gives excellent results
) just a while ago.
Three of the cylinders (left - right), had plugs basically swimming in water! But the last one was completely dry!
I cleaned them out decently including the leads, which had a slight amount of white cream on them.
I sniffed the fluid found in the holes and it was just water.
Also found two of the rubber boots damaged at the tip and one of them also had a cracked lead (orange part).
The spark plug of the cracked lead is quite corroded and I did the best I could in cleaning it for now.
Copper paste in the leads and back in they went with dry holes.
Now I'm wondering if this water presence is normal which should be considering condensations and short trips, but why was the last cylinder completely dry!
I had misfiring problems due to water in the wells in the spring so it's not always due to washing the engine.
