I'd use Marvel Mystery Oil and soak overnight.

Two clicks on the plug. The coils go one pretty easy. I used dielectric grease on the plug boots it made it easier. As for the Sea Foam idea I've never tried it that way. I have put it in the gas, oil, and sprayed the throttle body. It should do the job. At that point you may as well do all the cylinders.

mines done the same thing since i bought it hasn't got worse runs just fine and oil pressure holds around 50lbs when driving and 40 at an idle if something happens then i'll find a 6.0 to drop in it
