take a look at my spark plugs please

Oh, and if water is getting into #5, you should be seeing a loss of coolant over time OR a mixing of oil coolant which would retain your resevoir level. Probably already been answered, but do you see oil scum in the coolant resevoir? Frothy oil mix on the dipstick?

The plug pictures I posted in the first page are the set of 6 plugs I just replaced. (may not have a picture of each individual plug up though)

Not just 1 cylinder. At random one of the 6 will completely fail. I lose power, vibrations go through the car... Thats what the set comes out looking like.

The dipstick is normal. Just simple oil.
As far as I can tell, the coolant is clean too. No presence of oil in the reservoir.

I never need to add coolant too. There is no smoke I can detect in the exhaust. Hand stays dry if I place it near the exhaust.
