Most of those reading this will know that I've now replaced all my coils with Accel components originally designed for a SOHC 4.6. They work just fine. FWIW, although I found oil in several wells, it had not gotten as far as the coil body in any case. The boot was messy, but not the coil itself. Since the well is composite next to the boot, I believe the oil to be a 'red herring'.
