You have antifreeze in your number 5 plug linclon town car 1997?
Finding antifreeze in the #5 spark plug cylinder of a 1997 Lincoln Town Car is a serious problem. This indicates a head gasket leak or a cracked cylinder head. Antifreeze shouldn't be in the cylinders; it belongs in the cooling system. This is not something you should try to fix yourself. You need to take your car to a qualified mechanic immediately. Continuing to drive the car with this problem could cause significant and costly engine damage.
