Lincoln Navigator Check Engine Light due to Water/Coolant in Spark Plug Recesses
Lincoln Navigator Problem
Average Mileage: 144,750 mi (125,000 mi - 155,000 mi)
Replaced spark plugs and since then I have to drain water from the spark plug holes. Was both sides but now just the drivers side. Back holes are the worst. Siliconed the wire harness but still occurs. Does the area need to "breathe"? Seems that if that is the problem, high humidity would condensate and drip down in the plug holes. But after hard rains with no driving, the problem occurs. Any ideas? firstname.lastname@example.org
