Thread: Spark Plugs

I've just changed the Plugs on my 1999 P38 and each plug is half sooty & half clean.
My concern is there is some water leaking through & ''cleaning'' the plugs on one side??

Has anyone ever had this before with NGK Platinum plugs??

Any advice welcome.

Thanks.

Just the way the engine runs rich when cold, they should normally burn clean as they get hot. Nothing abnormal about them, water makes plugs go a rich dark brown.
