2003 4.6 Blown Out Spark Plug
4x4 XLT Ext Cab#7 plug blew out, bent plug bottom tip and damaged threads. Installed new plug and sat coil on it (broken bolt hold down) and limped home.230,000 miles on engine, so is a costly time-sert kit worth it? Assume from other posts that thread chaser and heli coils are unreliable.Appreciate any insight.
