Spark plugs

[Richieboy]

Heavy white ash wow don't know how she was still running. There were boch plugs so I put champs in What cause the white ash

Ash is caused by diff types of oil by products pulled through the pcv or by fuel additives. If problem persists try switching oil types or fuel types. If plugs are consistently white but no residual then it's running to hot or wrong plug heat range used. Coolant will leave a light white residual but no ash.
